Detailed explanations for NLE Paediatric Nursing — Communicable & Infectious Diseases in Children (IMCI). This page treats you like a serious reviewer: we unpack the concepts thoroughly, show worked examples of how Professional Regulation Commission (PRC) — Board of Nursing frames Communicable & Infectious Diseases in Children (IMCI) questions, and explain the underlying reasoning that gets you to the right answer every time.

Exam context

The Philippine Nurse Licensure Examination (PNLE) is conducted by Professional Regulation Commission (PRC) — Board of Nursing and is scheduled for Bi-annual. The Paediatric Nursing subtest is marked as "Core" in the official pattern, and Communicable & Infectious Diseases in Children (IMCI) appears in position 6th of 6 in the NLE Paediatric Nursing review rotation. Passing mark: 75% weighted average with no sub-test below 60%. Recent NLE 2026 papers have drawn roughly 50 questions from this subject.

Communicable & Infectious Diseases in Children (IMCI) - Detailed Explanation

Communicable and infectious diseases remain among the leading causes of morbidity and mortality among Filipino children under five years old. As a BSN graduate preparing for the NLE, you must master the hallmark signs, transmission routes, isolation precautions, complications, and management of the most common childhood infections — measles, mumps, varicella, rubella, pertussis, diphtheria, dengue, and diarrhoeal disease. Equally important is the Integrated Management of Childhood Illness (IMCI) strategy, a WHO/UNICEF/DOH framework that guides nurses and other frontline healthcare workers in systematically assessing, classifying, treating, counselling, and following up sick children under five at the primary-care level. Under RA 9173 (Philippine Nursing Act of 2002), the professional nurse is accountable for accurate clinical assessment, timely referral, health teaching, and implementation of DOH-prescribed disease control programs. This chapter integrates the DOH Expanded Program on Immunization (EPI) and Garantisadong Pambata (GP), which are critical for NLE scenario-type questions. Mastery of this chapter is essential — expect at least 10–15 NLE items drawn from this content area.

Concepts

Measles (Rubeola) — Airborne Exanthem with Koplik Spots

Measles is caused by the measles virus and is one of the most contagious infectious diseases known. Transmission is AIRBORNE — the virus travels via respiratory droplet nuclei that remain suspended in the air for up to two hours, meaning a child does NOT have to be in direct contact with an infected person to acquire the disease. This is why airborne precautions (N95 mask, negative-pressure room, door closed) are mandatory for hospitalised measles patients. The classic presentation follows a predictable prodromal phase of 3–5 days with the hallmark '3 C's': Cough, Coryza (profuse runny nose), and Conjunctivitis (red, watery eyes), along with high-grade fever and photophobia (sensitivity to light — dim the room). The PATHOGNOMONIC sign appearing before the rash is KOPLIK SPOTS — tiny bluish-white spots on a red base found on the buccal mucosa (inside the cheek, opposite the lower molars). They are described as 'grains of sand on a red background.' Koplik spots appear 1–2 days BEFORE the rash, making them extremely important for early diagnosis. The NLE will ask you to identify Koplik spots as the FIRST or EARLIEST sign specific to measles. The maculopapular rash appears first on the FACE and HAIRLINE and spreads DOWNWARD (cephalocaudal progression) to the neck, trunk, extremities, and finally the feet. The rash later turns brownish and fades in the same top-to-bottom order. Fever typically begins to subside as the rash reaches the feet. MANAGEMENT is supportive: adequate fluids, paracetamol for fever, rest, and dim lighting for photophobia. The critical intervention specific to measles is VITAMIN A SUPPLEMENTATION — given to ALL children with measles regardless of nutritional status because measles rapidly depletes Vitamin A stores, and deficiency worsens complications. Doses: <6 months: 50,000 IU; 6–11 months: 100,000 IU; ≥12 months: 200,000 IU — given on Day 1 and Day 2. COMPLICATIONS: PNEUMONIA is the #1 cause of death in children with measles (caused by secondary bacterial infection). Others include otitis media, croup, diarrhoea, and encephalitis. Prevention: measles-containing vaccine (MCV1 at 9 months, MCV2 at 12–15 months under EPI).

Examples

Koplik spots + 3 C's + cephalocaudal rash = classic measles presentation. The nurse's priority intervention unique to measles is Vitamin A. Airborne precautions prevent nosocomial transmission.

Scenario

A 2-year-old child is brought to the RHU with 4 days of high fever, runny nose, cough, and red watery eyes. The nurse inspects the mouth and sees tiny whitish spots on the inner cheek. A red rash is beginning to appear on the face.

Solution

The nurse correctly identifies KOPLIK SPOTS on the buccal mucosa — the pathognomonic early sign of measles. The nurse should: (1) place the child on AIRBORNE PRECAUTIONS; (2) report to the physician; (3) administer Vitamin A supplementation; (4) provide supportive care (fluids, antipyretics, dim lighting); (5) counsel the mother on home care and when to return (signs of pneumonia, convulsions, ear discharge).

While encephalitis is the most SERIOUS complication, PNEUMONIA (due to secondary bacterial infection) is the MOST COMMON cause of measles-related death in children. This distinction is a favourite NLE trap.

Scenario

An NLE item asks: 'Which complication is the LEADING CAUSE OF DEATH in children with measles?' Options: A) Encephalitis B) Otitis media C) Pneumonia D) Diarrhoea

Solution

Answer: C) Pneumonia

Applications

Apply airborne precautions immediately upon suspicion of measles — before laboratory confirmation
Administer Vitamin A supplementation on Day 1 and Day 2 of illness
Dim lighting and reduce environmental stimuli to manage photophobia
Monitor for signs of pneumonia (tachypnoea, chest indrawing, grunting) — the deadliest complication
Educate the mother to continue breastfeeding and encourage adequate fluid intake
Report confirmed measles cases to the local epidemiology surveillance unit (LESU) — notifiable disease in the Philippines
Check immunisation status and vaccinate susceptible contacts within 72 hours of exposure (post-exposure prophylaxis)

Misconceptions

MISCONCEPTION: Koplik spots appear WITH or AFTER the rash. TRUTH: Koplik spots appear 1–2 days BEFORE the rash — they are the earliest specific sign.
MISCONCEPTION: Measles requires only droplet precautions. TRUTH: Measles is AIRBORNE — requires N95 respirator, not just surgical mask.
MISCONCEPTION: Vitamin A is only given to malnourished children with measles. TRUTH: Vitamin A is given to ALL children with measles regardless of nutritional status.
MISCONCEPTION: The rash spreads from trunk to head. TRUTH: The rash spreads CEPHALOCAUDALLY — from face/hairline downward to the feet.

Common Exam Questions

Example

A child presents with fever, cough, and coryza. The nurse notes small bluish-white spots on the buccal mucosa. This finding is MOST consistent with: A) Mumps B) Measles C) Rubella D) Roseola — Answer: B

Approach

The NLE will present a clinical vignette and ask you to identify the EARLIEST or MOST SPECIFIC sign of measles. Always choose KOPLIK SPOTS — they are pathognomonic (only seen in measles) and appear BEFORE the rash.

Question Type

Identification of pathognomonic sign

Example

A child is admitted with confirmed measles. Which nursing intervention is SPECIFIC to this disease? A) Administer Vitamin C B) Apply calamine lotion C) Administer Vitamin A D) Give antihistamines — Answer: C

Approach

When asked the PRIORITY or SPECIFIC intervention for measles (beyond general supportive care), the answer is VITAMIN A supplementation. For isolation, always answer AIRBORNE precautions.

Question Type

Priority nursing intervention

Example

'The nurse monitors the child with measles most closely for which complication?' — Pneumonia, because it is the leading cause of death.

Approach

Distinguish between 'most serious' (encephalitis) and 'most common cause of death' (pneumonia). The NLE often tests this distinction.

Question Type

Complication identification

Key Points To Remember

Transmission: AIRBORNE — use airborne precautions (N95, negative-pressure room)
Hallmark: KOPLIK SPOTS on buccal mucosa — appear BEFORE the rash (pathognomonic)
The '3 C's': Cough, Coryza, Conjunctivitis — plus high fever and photophobia
Rash spreads CEPHALOCAUDALLY (head to feet) — maculopapular, fades in same order
Give VITAMIN A to ALL children with measles — reduces severity and mortality
Top cause of death: PNEUMONIA (secondary bacterial infection)
Other complications: otitis media, encephalitis
Prevention: EPI vaccine — MCV1 at 9 months, MCV2 at 12–15 months
Contagious period: 4 days before to 4 days after rash onset
Dim the room — child has photophobia

Mumps (Epidemic Parotitis) — Painful Parotid Swelling

Mumps is caused by the mumps virus and transmitted via DROPLET transmission (large respiratory droplets that travel less than 1 metre — requires a surgical mask, not N95). It primarily affects the salivary glands, with the PAROTID GLAND (the largest salivary gland, located just in front of and below the ear) being most commonly affected. The classic presentation includes LOW-GRADE FEVER, HEADACHE, and then the hallmark PAINFUL SWELLING OF ONE OR BOTH PAROTID GLANDS. The swelling causes the face to look puffy or chipmunk-like. The swelling is painful, particularly when eating sour or acidic foods (which stimulate saliva production and worsen pain — so patients are told to AVOID SOUR FOODS). Pain is also worse with chewing and swallowing. MANAGEMENT is supportive: analgesics and antipyretics (paracetamol or ibuprofen), SOFT BLAND DIET to minimise chewing pain, warm or cool compresses applied to the parotid area for comfort, increased fluid intake, and DROPLET PRECAUTIONS. COMPLICATIONS are what the NLE tests most heavily: - ORCHITIS (testicular inflammation): occurs in post-pubertal males — presents as sudden testicular pain and swelling, usually unilateral. While painful, it rarely causes infertility when unilateral. Bilateral orchitis can impair fertility. Management includes scrotal support, ice packs, and analgesics. - OOPHORITIS (inflammation of the ovaries) in post-pubertal females — may cause lower abdominal pain. - VIRAL MENINGITIS and ENCEPHALITIS. - SENSORINEURAL DEAFNESS (sudden, usually unilateral) — a rare but permanent complication. - PANCREATITIS (epigastric pain, nausea, vomiting). Prevention is the MMR vaccine (Measles-Mumps-Rubella), given at 12–15 months and again at school entry.

Examples

Orchitis is the most feared complication of mumps in post-pubertal males. The nurse prioritises comfort measures and reassures the patient about prognosis, while monitoring temperature and pain levels.

Scenario

A 14-year-old male is admitted with fever and swollen, painful jaw area. He is in visible pain when he attempts to eat his snack. The nurse notes swelling just below and in front of both ears. Two days later, he develops sudden pain and swelling in the right testicle.

Solution

This patient has MUMPS with the complication of ORCHITIS. Nursing interventions: (1) Place on DROPLET PRECAUTIONS; (2) Provide scrotal SUPPORT (briefs or improvised support); (3) Apply ICE PACKS to the scrotum for comfort; (4) Administer prescribed analgesics; (5) Instruct the patient to AVOID SOUR FOODS; (6) Offer a SOFT BLAND diet; (7) Reassure the patient — unilateral orchitis rarely causes permanent infertility.

Applications

Apply droplet precautions — instruct visitors and family to wear surgical masks
Instruct the child and caregiver to AVOID SOUR, SPICY, or ACIDIC foods (citrus, vinegar, sinigang, achara) — these stimulate salivary flow and worsen pain
Offer soft, bland foods: lugaw, mashed potatoes, scrambled eggs, soup
Apply warm or cool compresses to the parotid area — whichever provides more comfort
In orchitis: provide scrotal support and ice packs, administer analgesics as ordered
Monitor for signs of meningitis: severe headache, stiff neck, photophobia
Educate about MMR vaccination for susceptible contacts

Misconceptions

MISCONCEPTION: Mumps requires airborne precautions. TRUTH: Mumps is transmitted via DROPLET — surgical mask and droplet precautions are sufficient.
MISCONCEPTION: Orchitis from mumps always causes infertility. TRUTH: BILATERAL orchitis may impair fertility; UNILATERAL orchitis rarely does.
MISCONCEPTION: Sour foods should be given to stimulate appetite. TRUTH: Sour foods WORSEN pain in mumps by stimulating salivary secretion — they must be AVOIDED.
MISCONCEPTION: The submandibular gland swells in mumps. TRUTH: The PRIMARY gland affected is the PAROTID gland, though submandibular may also swell.

Common Exam Questions

Example

A child with mumps cries when drinking orange juice. The nurse should: A) Administer analgesics before meals B) Encourage more citrus for Vitamin C C) Advise the mother to avoid sour and acidic foods D) Apply ice packs before meals — Answer: C

Approach

When the NLE asks about nursing instructions for a child with mumps, the key dietary teaching point is to AVOID SOUR/ACIDIC FOODS. This is the most-tested mumps-specific intervention.

Question Type

Dietary instruction

Example

An 18-year-old male with mumps reports sudden right testicular pain. The nurse recognises this as: — Answer: Orchitis, a complication of mumps.

Approach

If the vignette involves an adolescent or adult male with mumps, always watch for orchitis as the key complication to monitor. The NLE may ask you to identify this complication or describe the priority assessment.

Question Type

Complication identification in post-pubertal males

Key Points To Remember

Transmission: DROPLET — use droplet precautions (surgical mask, private room or cohorting)
Hallmark: Painful swelling of the PAROTID GLANDS — looks like 'chipmunk cheeks'
Pain is WORSE with sour/acidic foods — AVOID sour foods (key nursing instruction)
Diet: SOFT BLAND food — no sour, spicy, or hard foods
Primary complication in post-pubertal males: ORCHITIS (testicular inflammation — can affect fertility if bilateral)
Other complications: oophoritis, meningitis, encephalitis, sensorineural deafness, pancreatitis
Management: supportive — analgesics, compresses, soft diet, fluids
Prevention: MMR vaccine
No specific antiviral treatment

Varicella (Chickenpox) — Vesicular Rash in Crops

Varicella (chickenpox) is caused by the Varicella-Zoster Virus (VZV) and is highly contagious — more so than most other childhood infections. Transmission is both AIRBORNE (via respiratory droplet nuclei) AND by DIRECT CONTACT with vesicle fluid. This dual transmission route means BOTH airborne AND contact precautions are required. The hallmark is the distinctive PRURITIC (intensely itchy) VESICULAR RASH that appears in 'CROPS' — meaning new lesions keep forming over several days, so all stages of lesion development (macule → papule → vesicle → crust) are present SIMULTANEOUSLY on the body. This is the key distinguishing feature from smallpox (which had lesions all at the same stage). Each vesicle is described classically as a 'DEWDROP ON A ROSE PETAL' — a clear fluid-filled blister on a red base. The rash begins on the TRUNK and SCALP and spreads to the face and extremities (centrifugal from trunk outward — the opposite of measles). Contagious period: from 1–2 days BEFORE the rash appears until ALL LESIONS HAVE CRUSTED OVER. The child cannot return to school or group care until every single lesion is crusted — even one active vesicle means the child is still contagious. MANAGEMENT focuses on relieving the intense itching and preventing secondary bacterial infection from scratching: - CALAMINE LOTION — applied to vesicles for soothing and anti-itch effect - ANTIHISTAMINES (e.g., diphenhydramine) — to reduce pruritus - COOL BATHS (tepid or oatmeal baths) — relieve itching - KEEP NAILS SHORT AND CLEAN — prevents skin breakdown and secondary bacterial infection (staphylococcal or streptococcal) from scratching - Mittens for young infants and toddlers to prevent scratching - ACYCLOVIR — antiviral used for HIGH-RISK or IMMUNOCOMPROMISED children, adolescents, and adults; most effective when started within 24 hours of rash onset - ABSOLUTELY NEVER GIVE ASPIRIN to children with varicella — causes REYE'S SYNDROME (a life-threatening encephalopathy with fatty liver degeneration) Complications: secondary bacterial skin infection (most common), pneumonia (varicella pneumonia in adults/immunocompromised), encephalitis, cerebellar ataxia, congenital varicella syndrome (if infection occurs in first trimester of pregnancy). Prevention: Varicella vaccine (not yet part of routine EPI in the Philippines but highly recommended).

Examples

Aspirin in children with viral infections (especially varicella and influenza) is associated with Reye's syndrome — a life-threatening condition with cerebral oedema and hepatic failure. Paracetamol is the ONLY safe antipyretic choice.

Scenario

A 5-year-old with chickenpox is scratching intensely. The mother asks if she can give the child aspirin for the fever and discomfort.

Solution

The nurse must FIRMLY ADVISE against aspirin. Instruct the mother to use PARACETAMOL (acetaminophen) instead for fever. For itching: apply calamine lotion, give antihistamines as ordered, give cool oatmeal baths, keep the child's fingernails short and clean. Recommend mittens at night if the child scratches during sleep.

The rule is ALL lesions crusted — not most. Even one active vesicle represents infectious virus that can be transmitted via direct contact.

Scenario

A school nurse is deciding when a child with chickenpox can return to school. The child has had lesions for 6 days. On inspection: most lesions are crusted, but 3 vesicles on the abdomen still have fluid.

Solution

The child CANNOT return to school yet. The child is still CONTAGIOUS because not all lesions have crusted over. The child must remain isolated until EVERY SINGLE vesicle has formed a dry crust.

Applications

Apply BOTH airborne AND contact precautions in hospital settings
Apply calamine lotion to vesicles — use gentle dabbing, not rubbing
Administer prescribed antihistamines and monitor for sedation (especially in young children)
Provide tepid or colloidal oatmeal baths for pruritus relief
Keep fingernails SHORT and CLEAN — trim daily; use mittens for infants
Administer paracetamol for fever — NEVER aspirin or NSAIDs in children
Administer acyclovir as prescribed for immunocompromised children — start within 24 hours for maximum effectiveness
Educate the family on the infectious period — ALL lesions must be crusted before child can return to school or public areas
Monitor for secondary bacterial infection: watch for increasing redness, warmth, purulent discharge, and fever after the initial fever subsides

Misconceptions

MISCONCEPTION: Chickenpox only requires contact precautions. TRUTH: VZV is AIRBORNE AND contact — both types of precautions are needed.
MISCONCEPTION: The child can return to school once the rash starts to crust. TRUTH: ALL lesions must be completely crusted over — even one active vesicle means contagious.
MISCONCEPTION: Ibuprofen (an NSAID) is safer than aspirin for children with varicella. TRUTH: While ibuprofen is safer than aspirin, PARACETAMOL remains the PREFERRED antipyretic for varicella; some guidelines caution against all NSAIDs in varicella due to risk of necrotising fasciitis.
MISCONCEPTION: Varicella and smallpox rashes look the same. TRUTH: In varicella, lesions are in ALL STAGES simultaneously; in smallpox, all lesions are in the SAME stage.

Common Exam Questions

Example

A child with chickenpox has a temperature of 38.5°C. The nurse should administer: A) Aspirin 10 mg/kg B) Ibuprofen 200 mg C) Paracetamol 15 mg/kg D) Mefenamic acid — Answer: C (Paracetamol)

Approach

A very high-yield NLE topic: aspirin is CONTRAINDICATED in children with varicella. If any option includes aspirin for a child with chickenpox, it is WRONG. The correct antipyretic is always PARACETAMOL.

Question Type

Drug contraindication

Example

When can a child with chickenpox return to school? — When ALL lesions have crusted over (no active vesicles remain).

Approach

The NLE will test when a child is no longer contagious. The answer is always when ALL lesions have crusted — not when the child is afebrile, not after a set number of days.

Question Type

Return-to-school criteria

Example

A child with varicella is admitted to the paediatric ward. The nurse should implement: A) Contact precautions only B) Droplet precautions C) Airborne and contact precautions D) Standard precautions only — Answer: C

Approach

Varicella requires BOTH airborne AND contact precautions — not just one or the other. If only one precaution type is offered as an option, look for the answer that combines both.

Question Type

Isolation precautions

Key Points To Remember

Transmission: AIRBORNE + DIRECT CONTACT — requires BOTH airborne AND contact precautions
Hallmark: Pruritic vesicular rash in CROPS — all stages present simultaneously (macule, papule, vesicle, crust)
Vesicles described as 'DEWDROPS ON A ROSE PETAL' — clear fluid on red base
Rash begins on TRUNK and SCALP, then spreads outward (centrifugal — opposite of measles)
Contagious until ALL LESIONS ARE CRUSTED OVER
NEVER give ASPIRIN — risk of REYE'S SYNDROME
Use CALAMINE LOTION, antihistamines, cool baths, short nails
ACYCLOVIR for high-risk, immunocompromised, adolescents, adults
Keep nails short and clean to prevent secondary bacterial infection from scratching
Most common complication: secondary bacterial skin infection from scratching

Rubella (German Measles / 3-Day Measles) — Congenital Risk

Rubella is caused by the rubella virus and is transmitted via DROPLET. In the child, it is a relatively MILD ILLNESS — low-grade fever, a pink maculopapular rash that lasts only about 3 days (hence '3-day measles'), and characteristically ENLARGED LYMPH NODES particularly at the POSTAURICULAR (behind the ear), OCCIPITAL (back of the head), and POSTERIOR CERVICAL (back of the neck) regions. This lymphadenopathy is the CLINICAL HALLMARK of rubella and distinguishes it from measles and other exanthems. The rash starts on the face and spreads downward like measles, but fades much faster (3 days vs. 7 days for measles). The child with rubella itself is not seriously ill — the GREATEST DANGER of rubella is NOT to the child, but to the DEVELOPING FETUS. If a pregnant woman (especially in the FIRST TRIMESTER) contracts rubella, the virus crosses the placenta and causes CONGENITAL RUBELLA SYNDROME (CRS), characterised by: - CATARACTS (eye opacity) - CONGENITAL HEART DEFECTS (patent ductus arteriosus, pulmonary artery stenosis) - SENSORINEURAL DEAFNESS - INTELLECTUAL DISABILITY - Microcephaly, hepatosplenomegaly, thrombocytopaenic purpura (blueberry muffin baby) The MOST CRITICAL nursing responsibility for a hospitalised child with rubella is to ENSURE THE CHILD DOES NOT COME INTO CONTACT WITH PREGNANT WOMEN. This includes pregnant healthcare workers, visitors, and other patients' mothers. MANAGEMENT is supportive: rest, fluids, analgesics/antipyretics for comfort. DROPLET PRECAUTIONS are implemented in the hospital. No specific antiviral is available. PREVENTION is via the MMR (Measles-Mumps-Rubella) vaccine, which provides excellent protection. Women of childbearing age who are seronegative should be vaccinated, but the MMR vaccine is a LIVE ATTENUATED vaccine and must NOT be given during pregnancy.

Examples

The postauricular and occipital lymphadenopathy is the classic hallmark of rubella. Protecting pregnant women from exposure is the highest priority nursing action specific to rubella — this is a classic NLE priority question.

Scenario

A 4-year-old child is admitted with low-grade fever and a faint pink rash that began on her face 2 days ago and is now on her trunk. The nurse palpates tender lymph nodes behind both ears and at the back of her head. The nurse also notes that the pregnant ward clerk frequently passes by this room.

Solution

This presentation is consistent with RUBELLA. The nurse must: (1) Implement DROPLET PRECAUTIONS; (2) IMMEDIATELY ensure the pregnant ward clerk and any other pregnant women do NOT enter or pass near the room; (3) Inform the physician and infection control team; (4) Provide supportive care; (5) Counsel the parents about the significance of keeping the child away from pregnant women.

Applications

Implement droplet precautions — place child in a private room or with other rubella patients
Immediately identify and prevent contact between the rubella-infected child and any pregnant women (staff, visitors, other patients' mothers)
Document and report to infection control and the attending physician
Counsel parents: mild illness for the child; explain the danger to pregnant women and why isolation is crucial
Teach about MMR vaccine for household contacts who are not immune
Reassure the caregiver that rubella in the child is manageable with supportive care

Misconceptions

MISCONCEPTION: Rubella is dangerous primarily for the infected child. TRUTH: Rubella is mild for the child — the PRIMARY DANGER is CONGENITAL RUBELLA SYNDROME in the fetus of a pregnant woman.
MISCONCEPTION: The MMR vaccine can be given to pregnant women to protect them. TRUTH: MMR is a LIVE ATTENUATED vaccine — CONTRAINDICATED in pregnancy. Women should be vaccinated BEFORE pregnancy.
MISCONCEPTION: Rubella and measles have the same rash duration. TRUTH: Rubella rash lasts 3 days; measles rash lasts 7 days. That is why rubella is called '3-day measles.'

Related Concepts

Congenital rubella syndrome vs. congenital CMV vs. congenital toxoplasmosis (TORCH infections)
MMR vaccine — live attenuated, contraindicated in pregnancy and immunosuppression
Postauricular lymphadenopathy as a clinical sign
First-trimester teratogenesis — critical period of organogenesis
Measles vs. rubella vs. roseola — differential diagnosis of childhood exanthems

Common Exam Questions

Example

A child with rubella is in a ward where a pregnant nurse works. The PRIORITY nursing action is: A) Administer MMR vaccine to the child B) Apply droplet precautions C) Ensure the pregnant nurse does not care for or enter the room D) Give Vitamin A supplementation — Answer: C

Approach

When rubella is the diagnosis and a pregnant person is in the scenario, the PRIORITY is always to PROTECT THE PREGNANT PERSON from exposure — this outweighs all other interventions.

Question Type

Priority nursing action

Example

A mother had rubella in her first trimester. The nurse anticipates the newborn may have: A) Cleft palate only B) Cataracts, congenital heart defects, and deafness C) Clubfoot D) Neural tube defects — Answer: B

Approach

The NLE tests whether you can link first-trimester rubella exposure to the classic triad of defects. The classic triad is cataracts + congenital heart defects + deafness.

Question Type

Congenital rubella syndrome identification

Key Points To Remember

Transmission: DROPLET precautions
Hallmark: Postauricular, occipital, and posterior cervical LYMPHADENOPATHY — appears before the rash
Rash: Pink maculopapular, lasts 3 days (hence '3-day measles'), spreads face to feet
Mild illness in children — the MAJOR DANGER is to the FETUS
CONGENITAL RUBELLA SYNDROME (CRS): cataracts, congenital heart defects, deafness, intellectual disability
First-trimester exposure causes the most severe CRS defects
CRITICAL NURSING RESPONSIBILITY: KEEP CHILD WITH RUBELLA AWAY FROM PREGNANT WOMEN
Prevention: MMR vaccine — do NOT give during pregnancy (live vaccine)
Management is supportive — no specific antiviral

Pertussis (Whooping Cough) — The Inspiratory Whoop

Pertussis is caused by the bacterium BORDETELLA PERTUSSIS and is transmitted via DROPLET. It is vaccine-preventable through the DPT (or pentavalent vaccine: DPT-Hib-HepB) given at 6, 10, and 14 weeks under the Philippine EPI. Despite vaccination, pertussis still causes outbreaks — particularly dangerous for young INFANTS under 6 months who are too young to be fully vaccinated. Pertussis has THREE stages: 1. CATARRHAL STAGE (1–2 weeks): Resembles a simple cold — runny nose, mild cough, low-grade fever. MOST CONTAGIOUS in this stage, but often not recognised as pertussis. 2. PAROXYSMAL STAGE (2–6 weeks): The hallmark — PAROXYSMS of rapid, forceful coughing (10–25 consecutive coughs in one exhalation) followed by a SUDDEN DEEP INSPIRATION that produces the characteristic high-pitched 'WHOOP' sound. The child's face may turn RED or CYANOTIC during the paroxysm. Episodes often end with vomiting. Young infants may NOT produce the whoop — instead they have APNEA (life-threatening cessation of breathing). 3. CONVALESCENT STAGE (weeks to months): Gradual recovery; cough gradually decreases. COMPLICATIONS: PNEUMONIA (most common), apnea (most dangerous in infants), seizures, encephalopathy, subconjunctival haemorrhages (from severe coughing), rectal prolapse. MANAGEMENT: - MACROLIDE ANTIBIOTICS: ERYTHROMYCIN, AZITHROMYCIN, or CLARITHROMYCIN — started early to eradicate the bacteria and reduce contagiousness; even in the paroxysmal stage, antibiotics are given to prevent spread to contacts. - Hospitalise young infants and severe cases. - Gentle suctioning for secretions. - Supplemental OXYGEN. - Small, frequent feeds (to reduce vomiting from post-tussive emesis). - Avoid triggers that provoke paroxysms (e.g., sudden stimuli, crying). - MONITOR CLOSELY FOR APNEA in infants — have resuscitation equipment at bedside. - DROPLET PRECAUTIONS. Key prevention: PERTUSSIS-CONTAINING VACCINES (pentavalent at 6, 10, 14 weeks) and Tdap booster for adolescents and adults, especially pregnant women (to protect newborns via passive immunity — 'cocooning strategy').

Examples

Young infants with pertussis do NOT produce the classic 'whoop' — they present with APNEA, which is immediately life-threatening. The nurse's priority is airway management and continuous monitoring. The apnea makes infant pertussis a medical emergency.

Scenario

A 3-month-old infant is brought to the emergency room because of repeated episodes of rapid coughing followed by brief periods where the baby stops breathing and turns blue. The mother says the baby has had a runny nose for 2 weeks before these episodes started.

Solution

This presentation is consistent with PERTUSSIS in a young infant, with the complication of APNEA. The nurse should: (1) Place on DROPLET PRECAUTIONS immediately; (2) Attach pulse oximeter and cardiorespiratory monitor; (3) Ensure resuscitation equipment (bag-valve mask, oxygen) is at bedside; (4) Notify physician urgently for admission; (5) Administer prescribed macrolide antibiotic; (6) Provide oxygen during apnoeic episodes; (7) Suction gently as needed; (8) Offer small, frequent feeds.

Applications

Implement DROPLET PRECAUTIONS until the child has completed 5 days of appropriate antibiotic therapy
Administer macrolide antibiotics (erythromycin, azithromycin, or clarithromycin) as prescribed
For infants: CONTINUOUS CARDIORESPIRATORY MONITORING for apnea; keep resuscitation equipment at bedside
Provide a CALM, QUIET environment — avoid stimuli that trigger paroxysms
Offer SMALL, FREQUENT MEALS — feed after a paroxysm (not during) to reduce vomiting
Use gentle, careful suction to clear secretions before they trigger coughing
Educate parents about completing the full antibiotic course and vaccination schedule
Offer pertussis booster (Tdap) to unvaccinated household contacts and pregnant mothers (cocooning)

Misconceptions

MISCONCEPTION: All children with pertussis produce the 'whoop.' TRUTH: Young INFANTS (especially <6 months) may ONLY present with APNEA — the whoop may be absent.
MISCONCEPTION: Penicillin is the antibiotic of choice for pertussis. TRUTH: MACROLIDES (erythromycin, azithromycin, clarithromycin) are the drugs of choice.
MISCONCEPTION: Pertussis is only dangerous in the paroxysmal stage. TRUTH: The CATARRHAL stage is when the child is MOST CONTAGIOUS — but it looks like a simple cold, so it's often missed.
MISCONCEPTION: Vaccinated children cannot get pertussis. TRUTH: Pertussis immunity wanes — older children and adults can still get pertussis and infect unvaccinated infants.

Common Exam Questions

Example

The physician orders antibiotic therapy for a child with pertussis. The nurse expects which antibiotic? A) Penicillin G B) Amoxicillin C) Azithromycin D) Tetracycline — Answer: C (Azithromycin — a macrolide; erythromycin also correct)

Approach

The NLE will ask for the antibiotic of choice for pertussis. Always answer MACROLIDE — erythromycin is the classic answer; azithromycin is acceptable and may be the correct modern answer.

Question Type

Drug of choice

Example

A 2-month-old has had a runny nose for 10 days and now has episodes of breath-holding and cyanosis. The nurse suspects: A) Pneumonia B) Pertussis C) Bronchiolitis D) Croup — Answer: B

A vignette describing an infant with apnea following 1–2 weeks of cold-like symptoms should raise suspicion for pertussis. Young infants do NOT whoop — they STOP BREATHING.

Question Type

Clinical identification in infants

Key Points To Remember

Cause: Bordetella pertussis (bacteria) — DROPLET transmission
Vaccine-preventable: DPT/pentavalent at 6, 10, 14 weeks (EPI)
Hallmark: Paroxysmal coughing ending in a HIGH-PITCHED INSPIRATORY 'WHOOP' + post-tussive vomiting
Young infants: may present with APNEA instead of whoop — MOST DANGEROUS group
Most contagious in the CATARRHAL stage (cold-like symptoms)
Treatment: MACROLIDE antibiotics — erythromycin, azithromycin, or clarithromycin
Most common complication: PNEUMONIA
Monitor for APNEA in infants — keep resuscitation equipment at bedside
Small frequent feedings to minimise post-tussive vomiting
Droplet precautions — isolate until 5 days of antibiotic therapy completed

Diphtheria — Pseudomembrane and Myocarditis

Diphtheria is caused by CORYNEBACTERIUM DIPHTHERIAE (a bacterium) and is transmitted via DROPLET. Like pertussis, it is vaccine-preventable through the DPT/pentavalent vaccine under the Philippine EPI. It can affect the pharynx (most common), larynx, nose, and even skin. The HALLMARK is the formation of a THICK GREYISH-WHITE PSEUDOMEMBRANE covering the TONSILS and PHARYNX. This membrane is tough, adherent, and BLEEDS if you attempt to remove it — DO NOT attempt to remove the membrane. The membrane can extend downward into the larynx and trachea, causing progressive AIRWAY OBSTRUCTION (the primary cause of death from local disease). Associated features include: sore throat, LOW-GRADE FEVER (the mild fever differentiates diphtheria from strep throat which causes high fever), hoarseness, and a 'BULL NECK' appearance from significant cervical lymphadenopathy and soft-tissue oedema. The C. diphtheriae bacteria produces an EXOTOXIN that spreads systemically and causes: - MYOCARDITIS (inflammation of the heart muscle) — the most serious systemic complication, can cause heart block, arrhythmias, and heart failure; patients must be on STRICT BED REST to minimise cardiac workload; cardiac monitoring is essential - NEUROPATHY/NEURITIS — CN palsy (soft palate palsy causing nasal voice and regurgitation, diplopia from oculomotor CN palsy), descending peripheral neuropathy MANAGEMENT — must be done urgently: 1. DIPHTHERIA ANTITOXIN (DAT) — the MOST IMPORTANT and SPECIFIC treatment; neutralises the circulating toxin; must be given even before culture results return (do not wait for confirmation); administer after a skin test for horse serum sensitivity (it is derived from horse serum) 2. ANTIBIOTICS (PENICILLIN or ERYTHROMYCIN) — kill the bacteria and end toxin production; given concurrently with antitoxin 3. KEEP EMERGENCY AIRWAY EQUIPMENT at bedside (tracheostomy tray, suction, oxygen) — airway obstruction is the primary immediate danger 4. STRICT BED REST — reduces cardiac workload during the myocarditis phase 5. CONTINUOUS CARDIAC MONITORING — for arrhythmias 6. SOFT DIET — minimise swallowing discomfort 7. DROPLET PRECAUTIONS CRITICAL RULE: DO NOT ATTEMPT TO REMOVE THE PSEUDOMEMBRANE — it will bleed profusely and may cause complete airway obstruction.

Examples

The pseudomembrane + bull neck + hoarseness + incomplete vaccination = diphtheria until proven otherwise. Airway protection is the immediate priority; antitoxin is the definitive treatment.

Scenario

An 8-year-old child with incomplete vaccination history presents with sore throat, hoarseness, and difficulty breathing. On inspection, the nurse notes a greyish-white membrane firmly covering the tonsils and extending toward the soft palate. The child's neck appears swollen.

Solution

The nurse suspects DIPHTHERIA. Priority actions: (1) Implement DROPLET PRECAUTIONS; (2) Keep AIRWAY EQUIPMENT at bedside — do not leave the child unattended; (3) DO NOT ATTEMPT TO REMOVE THE MEMBRANE; (4) Alert the physician IMMEDIATELY for antitoxin order; (5) Prepare for skin test before DAT administration; (6) Administer prescribed antibiotics; (7) Enforce STRICT BED REST; (8) Attach cardiac monitor; (9) Provide humidified oxygen.

Applications

Never attempt to remove the pseudomembrane — this is a cardinal rule in diphtheria nursing care
Keep a tracheostomy tray, suction equipment, and oxygen at the bedside at all times
Perform skin test for horse serum sensitivity BEFORE administering DAT
Administer DAT (diphtheria antitoxin) as ordered — the SPECIFIC treatment; do not delay pending culture
Enforce absolute strict bed rest to reduce cardiac workload during the myocarditis phase
Monitor cardiac rhythm continuously — report any arrhythmias immediately
Implement droplet precautions; educate family and staff
Provide a soft, easy-to-swallow diet; avoid hard or scratchy foods
Report to LESU — diphtheria is a notifiable disease under the Philippine Integrated Disease Surveillance and Response (PIDSR)

Misconceptions

MISCONCEPTION: Antibiotics alone are sufficient to treat diphtheria. TRUTH: Antibiotics kill the bacteria but do NOT neutralise the EXOTOXIN already in the bloodstream. ANTITOXIN is the specific treatment and must be given with antibiotics.
MISCONCEPTION: The pseudomembrane should be carefully peeled off to relieve airway obstruction. TRUTH: Removing the membrane causes BLEEDING and may precipitate COMPLETE AIRWAY OBSTRUCTION.
MISCONCEPTION: Diphtheria causes high fever like strep throat. TRUTH: Diphtheria typically causes LOW-GRADE fever — the combination of membrane + low fever + bull neck distinguishes it.

Related Concepts

EPI DPT/pentavalent vaccine — prevention of diphtheria
Exotoxin mechanism vs. endotoxin — clinical relevance
Cardiac monitoring — heart block and arrhythmias in myocarditis
Antitoxin vs. antibiotic therapy — different mechanisms
Croup vs. diphtheria — differential diagnosis (both cause hoarseness and stridor)

Common Exam Questions

Example

A nurse is caring for a child with diphtheria. Which action should the nurse AVOID? A) Maintaining airway equipment at bedside B) Enforcing strict bed rest C) Attempting to remove the pseudomembrane D) Administering diphtheria antitoxin — Answer: C

Approach

A favourite NLE question: 'Which action should the nurse AVOID?' In diphtheria, the answer is always DO NOT REMOVE THE PSEUDOMEMBRANE. If the question asks what the nurse should NOT do, identify 'removing the membrane' as the wrong action.

Question Type

Do NOT do — negative intervention

Example

The nurse prepares the PRIORITY treatment for a child with confirmed diphtheria. This is: A) Amoxicillin B) Diphtheria antitoxin C) Corticosteroid D) Erythromycin — Answer: B

Approach

The NLE will test: What is the SPECIFIC treatment for diphtheria? The answer is DIPHTHERIA ANTITOXIN (DAT) — not the antibiotic. Antibiotics are given concurrently but antitoxin is the PRIMARY specific treatment.

Question Type

Specific treatment identification

Key Points To Remember

Cause: Corynebacterium diphtheriae (bacterium) — DROPLET transmission
Hallmark: THICK GREYISH-WHITE PSEUDOMEMBRANE on tonsils/pharynx — DO NOT REMOVE (will bleed and obstruct airway)
'BULL NECK' appearance from cervical swelling and oedema
Low-grade fever (distinguishes from streptococcal pharyngitis which causes high fever)
Primary immediate danger: AIRWAY OBSTRUCTION from membrane extension
Systemic complication: MYOCARDITIS (exotoxin effect) — can cause arrhythmias and heart failure
SPECIFIC treatment: DIPHTHERIA ANTITOXIN (DAT) — given FIRST (do skin test for horse serum sensitivity)
Antibiotics: PENICILLIN or ERYTHROMYCIN — kill bacteria
STRICT BED REST — to protect the heart during myocarditis phase
Keep EMERGENCY AIRWAY EQUIPMENT at bedside — tracheostomy tray, suction, O2

Dengue Fever — Vector-Borne Disease Management

Dengue is caused by the dengue virus (4 serotypes: DENV 1–4) and is transmitted by the AEDES AEGYPTI MOSQUITO — a daytime biting mosquito that breeds in CLEAN STAGNANT WATER (e.g., flower vases, water containers, clogged drains, discarded tyres). There is NO human-to-human transmission — the vector (mosquito) is required. Dengue is one of the most common vector-borne diseases in the Philippines. CLINICAL PHASES: 1. FEBRILE PHASE (Days 1–3): Sudden high fever (39–40°C), SEVERE HEADACHE, RETRO-ORBITAL PAIN (pain behind the eyeballs — classic dengue sign), myalgia/arthralgia ('breakbone fever'), flushed face, anorexia, nausea/vomiting. A faint maculopapular rash may appear. 2. CRITICAL PHASE (Days 4–6): Fever decreases (DEFERVESCENCE — temperature drops). This is the MOST DANGEROUS PHASE. Plasma leaks from blood vessels into body cavities (pleural effusion, ascites), causing haemoconcentration (rising HAEMATOCRIT), thrombocytopaenia (dropping PLATELET COUNT), and risk of DENGUE HAEMORRHAGIC FEVER (DHF) and DENGUE SHOCK SYNDROME (DSS). The TOURNIQUET TEST (Rumpel-Leede Test) may be positive (≥10 petechiae in a 1-inch circle after blood pressure cuff inflation at the midpoint between systolic and diastolic for 5 minutes). 3. RECOVERY PHASE (Days 7–10): Fluid reabsorption, platelet count rises, general improvement. DENGUE WARNING SIGNS (require IMMEDIATE hospital admission — these indicate progression to severe dengue): - Severe ABDOMINAL PAIN or tenderness - Persistent VOMITING - MUCOSAL OR GUM BLEEDING - RESTLESSNESS or rapid deterioration - LETHARGY - Rapid DROP IN TEMPERATURE with COLD, CLAMMY SKIN (shock) - Liver enlargement >2 cm - Rapid increase in haematocrit with rapid decrease in platelet count MANAGEMENT: NO SPECIFIC ANTIVIRAL exists for dengue. Treatment is SUPPORTIVE: - FLUID MANAGEMENT is the CORNERSTONE — adequate oral or IV hydration to compensate for plasma leakage - Monitor PLATELET COUNT and HAEMATOCRIT closely (rising Hct = haemoconcentration = plasma leak) - PARACETAMOL for fever — NEVER ASPIRIN or NSAIDs (ibuprofen, mefenamic acid) — these increase bleeding risk due to platelet inhibition - Bed rest - Monitor for signs of bleeding: petechiae, ecchymosis, gum bleeding, melaena, haematuria - Platelet transfusion ONLY for active bleeding with very low platelets — NOT given prophylactically for low platelet count alone DOH 4-S PREVENTION STRATEGY: 1. SEARCH and DESTROY mosquito breeding sites (remove stagnant water containers) 2. SELF-PROTECTION measures (insect repellent, long sleeves, window screens, mosquito nets) 3. SEEK EARLY CONSULTATION at the first sign of fever 4. SUPPORT FOGGING — only during outbreaks (not as routine control — fogging kills adult mosquitoes but not larvae)

Examples

The DROP IN TEMPERATURE during the critical phase is a TRAP — many caregivers think the child is getting better when the fever breaks, but this is actually when dengue becomes most dangerous. Restlessness + cold clammy skin = early shock.

Scenario

A 7-year-old child in Cebu City has had high fever for 4 days. Today (Day 5), the mother notes the child's temperature is now normal, but the child is restless, not wanting to drink, and complaining of severe abdominal pain. The skin feels cool and clammy. Platelet count this morning was 40,000/mm³.

Solution

The child is exhibiting DENGUE WARNING SIGNS (severe abdominal pain + restlessness + cold clammy skin + thrombocytopaenia) during the CRITICAL PHASE of dengue. This indicates progression toward DENGUE SHOCK SYNDROME. The nurse should: (1) Assess vital signs (BP, PR, RR, capillary refill); (2) NOTIFY THE PHYSICIAN IMMEDIATELY; (3) Establish IV access and prepare for IV fluid resuscitation as ordered; (4) Continue to monitor platelet count and haematocrit; (5) Maintain the child on strict bed rest; (6) AVOID aspirin and NSAIDs; (7) Monitor urine output.

Applications

Educate families: Aedes aegypti is a DAY-BITER — use repellent DURING THE DAY, not only at night
Perform and teach the TOURNIQUET TEST as a bedside screening tool
Monitor platelet count and haematocrit trends (not single values) — trend is more important
Instruct families to seek consultation IMMEDIATELY if warning signs appear, especially when fever breaks (Day 4–6)
Administer PARACETAMOL for fever — clearly warn family about aspirin and ibuprofen
Maintain fluid balance record — input and output, urine output (adequate = ≥1 mL/kg/hour)
Counsel on DOH 4-S strategy for community-level prevention
Report dengue cases to LESU (dengue is notifiable under PIDSR)

Misconceptions

MISCONCEPTION: When the dengue fever breaks, the child is getting better. TRUTH: The CRITICAL PHASE occurs when fever DROPS (defervescence) — this is when plasma leakage and shock are most likely.
MISCONCEPTION: Aedes mosquitoes bite at night. TRUTH: Aedes aegypti is a DAYTIME BITER — peak biting times are early morning and late afternoon.
MISCONCEPTION: Fogging should be done routinely to prevent dengue. TRUTH: Fogging is recommended only DURING OUTBREAKS — routine fogging is not recommended and does not eliminate larvae.
MISCONCEPTION: Low platelet count always requires platelet transfusion. TRUTH: Platelet transfusion is given only for ACTIVE BLEEDING with critically low platelets — NOT routinely for low count alone.
MISCONCEPTION: Dengue can spread from person to person. TRUTH: Dengue requires a mosquito VECTOR — no direct human-to-human transmission.

Common Exam Questions

Example

A child with suspected dengue has a temperature of 38.9°C. Which medication should the nurse AVOID? A) Paracetamol B) Ibuprofen C) Cetirizine D) ORS — Answer: B (Ibuprofen — an NSAID)

Approach

The NLE will ask what medication to AVOID in dengue. Always answer ASPIRIN and/or NSAIDs (ibuprofen, mefenamic acid) — they inhibit platelet aggregation and worsen bleeding. Safe choice: PARACETAMOL.

Question Type

Drug contraindication

Example

A child with dengue on Day 5 has a sudden temperature drop and becomes restless with cold hands. The nurse should: A) Reassure the mother that the fever has broken B) Offer more oral fluids and observe C) Notify the physician immediately — this is a warning sign D) Discharge the child — Answer: C

Approach

The NLE tests knowledge of dengue warning signs. Memorise: severe abdominal pain, persistent vomiting, mucosal bleeding, restlessness/lethargy, cold clammy skin with temperature drop.

Question Type

Warning sign identification

Key Points To Remember

Vector: AEDES AEGYPTI — DAY-BITING mosquito, breeds in CLEAN STAGNANT WATER
No human-to-human transmission — mosquito required
Classic signs: sudden high fever, RETRO-ORBITAL PAIN, severe headache, myalgia ('breakbone fever')
Tourniquet test: positive (≥10 petechiae per 1-inch square)
WARNING SIGNS: severe abdominal pain, persistent vomiting, mucosal bleeding, restlessness, cold clammy skin (shock)
CRITICAL PHASE: when fever drops (defervescence, Days 4–6) — most dangerous time for plasma leakage and shock
NO specific antiviral — SUPPORTIVE CARE with FLUID MANAGEMENT is the priority
PARACETAMOL for fever — NEVER ASPIRIN or NSAIDs (increase bleeding risk)
Monitor: PLATELET COUNT (dropping) and HAEMATOCRIT (rising) daily
DOH 4-S: Search and Destroy, Self-protection, Seek early consultation, Support fogging

Diarrhoeal Disease and ORS/ZINC Management (IMCI Dehydration Plans)

Diarrhoeal disease is a leading cause of under-5 mortality in the Philippines and worldwide. The greatest danger is DEHYDRATION, which can rapidly lead to hypovolaemic shock and death. The most common cause in children is ROTAVIRUS (now vaccine-preventable), followed by bacterial and parasitic causes from contaminated food and water. DEHYDRATION ASSESSMENT (IMCI-based): The nurse assesses three clinical signs to classify the degree of dehydration: 1. General condition (alert/restless/lethargic) 2. Eyes (normal/sunken/very sunken) 3. Skin turgor (goes back quickly/slowly/very slowly — 'skin pinch') 4. Drinking (drinks normally/drinks eagerly/not able to drink) DEHYDRATION CLASSIFICATION AND TREATMENT (IMCI): PLAN A — NO DEHYDRATION: - Child is alert, eyes normal, skin turgor normal, drinking normally - Managed AT HOME - Instructions: EXTRA FLUIDS after each loose stool; ORS 50–100 mL after each stool for children <2 years, 100–200 mL after each stool for children ≥2 years - ZINC supplementation: 10 mg/day for infants <6 months; 20 mg/day for children ≥6 months — for 10–14 days - CONTINUE FEEDING/BREASTFEEDING throughout — do NOT restrict food - Teach warning signs that require returning to the facility immediately PLAN B — SOME DEHYDRATION: - Child has 2 or more signs: restlessness, sunken eyes, skin goes back slowly, drinks eagerly - Managed at the HEALTH FACILITY under supervision - ORS: 75 mL/kg over 4 HOURS — given slowly in small sips; if child vomits, wait 10 minutes then resume slowly - Reassess after 4 hours and reclassify — if better, proceed to Plan A; if same/worse, proceed to Plan C - ZINC supplementation as above PLAN C — SEVERE DEHYDRATION: - Child has 2 or more signs: lethargic/unconscious, very sunken eyes, skin goes back very slowly, not able to drink - MEDICAL EMERGENCY — IV FLUIDS IMMEDIATELY - Standard: RINGER'S LACTATE (or normal saline if not available) — 100 mL/kg divided: - For infants <12 months: 30 mL/kg in 1 hour, then 70 mL/kg in 5 hours - For children ≥12 months: 30 mL/kg in 30 minutes, then 70 mL/kg in 2.5 hours - As soon as child can drink, start ORS - Reassess every 15–30 minutes ZINC SUPPLEMENTATION — CORNERSTONE OF DIARRHOEA MANAGEMENT: - ZINC supplementation REDUCES the DURATION, SEVERITY, and RECURRENCE of diarrhoea - Dose: INFANTS <6 MONTHS: 10 mg/day; CHILDREN ≥6 MONTHS: 20 mg/day - Duration: 10–14 DAYS (even after diarrhoea resolves — to replenish zinc stores and prevent future episodes) - Zinc is available as dispersible tablets — dissolve in a small amount of breastmilk, ORS, or water ORS FORMULA (WHO Low-Osmolarity ORS): sodium 75 mEq/L, chloride 65 mEq/L, glucose 75 mmol/L, potassium 20 mEq/L, citrate 10 mEq/L — osmolarity 245 mOsm/L. Lower osmolarity than the old formula — reduces vomiting and stool output. FEEDING: CONTINUE breastfeeding throughout — breast milk is protective and provides nutrition. For non-breastfed children, continue age-appropriate foods. DO NOT withhold food — this prolongs recovery and worsens malnutrition. PREVENTION: Hand washing with soap and water (before eating, after defaecating), safe water (boiling or use of water purification), proper food handling, sanitation, and rotavirus vaccination.

Examples

Restlessness + sunken eyes + slow skin turgor + drinks eagerly = 2+ signs of SOME dehydration = Plan B. After 4-hour ORS rehydration, the child is reassessed. If fully rehydrated, Plan A is initiated and the mother is educated on home management.

Scenario

A mother brings her 10-month-old infant to the BHU. The infant has had watery diarrhoea 6 times in the past 24 hours. On assessment: the infant is restless, eyes appear sunken, skin goes back slowly when pinched, and is drinking eagerly when offered water.

Solution

Assessment reveals SOME DEHYDRATION. The nurse implements PLAN B: (1) Supervise ORS administration at 75 mL/kg over 4 hours; (2) Demonstrate to the mother how to give ORS — small sips, frequently; (3) Prescribe ZINC 20 mg/day for 10–14 days (child is ≥6 months); (4) Continue age-appropriate feeding and breastfeeding; (5) Reassess after 4 hours; (6) If improved, transition to Plan A with discharge instructions.

Applications

Teach ORS preparation: dissolve 1 sachet in 1 litre of boiled, cooled water; do not add sugar or salt
Demonstrate how to give ORS — by spoon for young infants; small sips every few minutes
Administer ZINC as dissolved tablets in a small amount of liquid — continue for full 10–14 days
Continue breastfeeding throughout diarrhoeal illness — breast milk reduces severity and duration
Monitor weight, urine output, and vital signs as indicators of rehydration progress
Educate mothers on WHEN TO RETURN: blood in stool, repeated vomiting, high fever, sunken eyes, poor feeding, child not improving after 3 days
Implement Plan C immediately for severe dehydration — IV access, fluid calculation, close monitoring
Reinforce handwashing with soap as the single most effective prevention measure

Misconceptions

MISCONCEPTION: Food should be withheld during diarrhoea to 'rest the gut.' TRUTH: CONTINUE FEEDING AND BREASTFEEDING throughout — withholding food prolongs illness and worsens malnutrition.
MISCONCEPTION: Plain water is as effective as ORS for rehydration. TRUTH: ORS contains the correct balance of electrolytes and glucose — plain water does not replace lost sodium and potassium and can cause dangerous electrolyte imbalances.
MISCONCEPTION: Zinc should only be given for the duration of diarrhoea. TRUTH: Zinc must be given for the FULL 10–14 DAYS — even after diarrhoea resolves — to replenish stores and prevent future episodes.
MISCONCEPTION: Antibiotics are routinely given for all diarrhoea. TRUTH: Most childhood diarrhoea is VIRAL (rotavirus) and does NOT require antibiotics. Antibiotics are given only for specific bacterial or parasitic causes.

Common Exam Questions

Example

A child has diarrhoea, is irritable, has sunken eyes, and is drinking eagerly. The nurse implements: A) Plan A — extra fluids at home B) Plan B — ORS 75 mL/kg over 4 hours at facility C) Plan C — IV fluids immediately D) Plan A — zinc only — Answer: B

Approach

The NLE will describe dehydration signs and ask which Plan to implement. Count the signs: none = Plan A, 2+ moderate signs = Plan B, 2+ severe signs = Plan C.

Question Type

Plan selection based on dehydration signs

Example

A 9-month-old child has diarrhoea. The nurse prepares zinc supplementation. The correct dose is: A) 10 mg/day for 7 days B) 20 mg/day for 10–14 days C) 10 mg/day for 10–14 days D) 20 mg/day for 5 days — Answer: B

Approach

Memorise the zinc doses: <6 months = 10 mg/day; ≥6 months = 20 mg/day — both for 10–14 days. The NLE may give the age and ask for the correct dose.

Question Type

Zinc dosage

Key Points To Remember

Primary danger of diarrhoea: DEHYDRATION — assess degree first before selecting Plan A, B, or C
PLAN A: No dehydration — home management with extra ORS + ZINC + CONTINUE FEEDING
PLAN B: Some dehydration — supervised ORS 75 mL/kg over 4 HOURS at the facility
PLAN C: Severe dehydration — IV RINGER'S LACTATE immediately
ZINC: <6 months = 10 mg/day; ≥6 months = 20 mg/day — for 10–14 DAYS
CONTINUE BREASTFEEDING/FEEDING throughout — do NOT withhold food
DOH uses LOW-OSMOLARITY ORS (osmolarity 245 mOsm/L)
Rotavirus = most common viral cause — vaccine available
Prevent with handwashing, safe water, sanitation, rotavirus vaccine
Key nursing role: educate mothers on ORS preparation, zinc use, and when to return to facility

Integrated Management of Childhood Illness (IMCI) — Assess, Classify, Treat, Counsel, Follow Up

IMCI (Integrated Management of Childhood Illness) is a strategy developed by WHO and UNICEF, adopted by the Philippine DOH, for managing the sick child under 5 years old at the PRIMARY CARE level. The key principle of IMCI is INTEGRATED management — rather than treating one disease at a time, the nurse assesses the WHOLE child for all major causes of illness simultaneously, then classifies, treats, counsels, and follows up. IMCI applies to children aged 1 WEEK to 5 YEARS and uses TWO AGE-BASED ASSESSMENT CHARTS: - Chart 1: THE YOUNG INFANT (1 week – 2 months) - Chart 2: THE SICK CHILD (2 months – 5 years) THE IMCI PROCESS (the sequence every nurse must know): STEP 1 — ASK AND ASSESS: Greet the caregiver, ask about the child's main complaint, then ALWAYS CHECK FOR GENERAL DANGER SIGNS first. GENERAL DANGER SIGNS (apply to ALL sick children 2 months – 5 years): - UNABLE TO DRINK or breastfeed - VOMITS EVERYTHING - CONVULSIONS currently or during this illness - LETHARGIC or UNCONSCIOUS (abnormally sleepy or hard to wake) Any ONE general danger sign = URGENT REFERRAL (PINK classification) STEP 2 — CLASSIFY BY COLOUR-CODED SYSTEM: - 🔴 PINK = URGENT referral/hospitalisation needed — SEVERE DISEASE (e.g., severe dehydration, severe pneumonia, severe malnutrition, general danger sign present) - 🟡 YELLOW = Specific treatment and home care with follow-up — moderate disease (e.g., some dehydration, non-severe pneumonia, anaemia, malnutrition) - 🟢 GREEN = Home management with advice — no identifiable disease (e.g., no dehydration, no pneumonia) STEP 3 — IDENTIFY TREATMENT: Based on classification: - PINK: Refer URGENTLY; give pre-referral treatment as indicated (e.g., first dose of antibiotic, ORS in shock, Vitamin A for measles) - YELLOW: Give specific treatment at the facility (e.g., ORS Plan B, oral antibiotic for pneumonia, antimalarial) - GREEN: Give advice on home care, feeding, fluids, and when to return STEP 4 — COUNSEL: Provide health education to the caregiver: - How to give oral medication at home - How to give ORS - When to return IMMEDIATELY (warning signs) and when to come for follow-up - Feeding advice (breastfeeding, complementary feeding) - Immunisation status and catch-up STEP 5 — FOLLOW UP: Schedule and conduct follow-up visits to monitor progress. MAIN SYMPTOMS ASSESSED in children 2 months – 5 years: 1. COUGH OR DIFFICULT BREATHING — assess respiratory rate and for chest indrawing/stridor 2. DIARRHOEA — assess dehydration and classify 3. FEVER — assess for malaria, measles, dengue 4. EAR PROBLEM 5. NUTRITIONAL STATUS — weight, oedema, MUAC (Mid-Upper Arm Circumference), pallor for anaemia 6. IMMUNISATION STATUS 7. FEEDING ASSESSMENT FAST-BREATHING THRESHOLDS (IMCI pneumonia cut-offs — must memorise): - AGE <2 months: ≥60 breaths per minute = fast breathing - AGE 2–12 months: ≥50 breaths per minute = fast breathing - AGE 12 months–5 years: ≥40 breaths per minute = fast breathing PNEUMONIA CLASSIFICATION: - FAST BREATHING ONLY: Non-severe pneumonia → ORAL AMOXICILLIN + home care + follow-up in 2 days - CHEST INDRAWING and/or STRIDOR: Severe pneumonia → URGENT REFERRAL (PINK); first dose of antibiotic before referral THE YOUNG INFANT (1 week – 2 months) IMCI: Young infants deteriorate fastest and have different presentations. The nurse assesses for POSSIBLE SERIOUS BACTERIAL INFECTION OR VERY SEVERE DISEASE. Danger signs in young infants triggering URGENT REFERRAL: - NOT FEEDING WELL - CONVULSIONS - FAST BREATHING (≥60/min) - SEVERE CHEST INDRAWING - FEVER (≥37.5°C) OR LOW BODY TEMPERATURE (<35.5°C) - Movement ONLY WHEN STIMULATED or NO MOVEMENT at all The nurse ALWAYS checks for JAUNDICE, assesses BREASTFEEDING ATTACHMENT AND TECHNIQUE, corrects any feeding problems, and keeps the young infant WARM during referral (prevents hypothermia).

Examples

Fast breathing (45 ≥ 40/min threshold) without chest indrawing = non-severe pneumonia = YELLOW classification = oral antibiotic at home. The nurse must count respirations for a FULL minute — not estimated.

Scenario

A mother brings a 14-month-old boy with 3 days of cough and fever. The nurse counts the respiratory rate: 45 breaths per minute. No chest indrawing. No stridor. The child can drink. No history of convulsions. The child is alert.

Solution

Assessment: No general danger signs. Respiratory rate 45/min = FAST BREATHING for age 12–59 months (cut-off ≥40/min). No chest indrawing. IMCI Classification: NON-SEVERE PNEUMONIA (YELLOW). Treatment: Oral AMOXICILLIN; continue feeding; ORS for fever; Paracetamol. Counselling: Teach mother to give medications, continue breastfeeding/feeding, and RETURN IMMEDIATELY if: child is not able to drink, condition worsens, fast breathing worsens, develops chest indrawing, or fever continues >3 days. Follow-up in 2 days.

Young infants with danger signs are classified as PINK and require URGENT referral. Hypothermia in a young infant is a serious danger sign — maintain warmth during transfer. The nurse gives pre-referral treatment to stabilise before transport.

Scenario

A 3-week-old infant is brought to the RHU. The mother says the baby has not been feeding well for 2 days and feels cold to touch. The nurse measures temperature: 35.0°C. The baby moves only when stimulated.

Solution

This young infant has MULTIPLE danger signs: (1) not feeding well; (2) low body temperature (<35.5°C) = hypothermia; (3) moves only when stimulated = altered level of consciousness. IMCI Classification: POSSIBLE SERIOUS BACTERIAL INFECTION / VERY SEVERE DISEASE = PINK = URGENT REFERRAL. Pre-referral actions: (1) Keep infant WARM — skin-to-skin contact (kangaroo care), wrap with warm blanket; (2) Give first dose of intramuscular antibiotics as prescribed; (3) Ensure airway and breathing; (4) Transport urgently with mother maintaining warmth.

Applications

Always check for GENERAL DANGER SIGNS first in every sick child before assessing the main complaint
Count respiratory rate for a FULL 60 seconds — not 15 or 30 seconds — for accurate pneumonia assessment
Use the correct age-based fast-breathing cut-off: memorise <2 mo ≥60, 2–12 mo ≥50, 1–5 yr ≥40
Apply the colour-coded classification system to prioritise care and determine disposition
For PINK classifications, give pre-referral treatment before transporting the child
Counsel every caregiver on feeding, medications, and WARNING SIGNS requiring immediate return
For young infants: ALWAYS check temperature (hypo and hyper), jaundice, breastfeeding technique
Keep young infants WARM during assessment and referral — prevent hypothermia
Check and update immunisation status at every IMCI visit
Follow up all YELLOW cases in 2 days — reassess and reclassify

Misconceptions

MISCONCEPTION: IMCI only applies to one disease at a time. TRUTH: IMCI is INTEGRATED — the nurse assesses ALL major causes simultaneously, not one by one.
MISCONCEPTION: Chest indrawing indicates non-severe pneumonia. TRUTH: Chest indrawing classifies as SEVERE pneumonia = PINK = URGENT REFERRAL. Only fast breathing without chest indrawing = non-severe (YELLOW).
MISCONCEPTION: IMCI uses the same chart for all children under 5. TRUTH: IMCI has TWO charts — one for YOUNG INFANTS (1 week–2 months) and one for the SICK CHILD (2 months–5 years).
MISCONCEPTION: A normal temperature in a young infant means the child is not seriously ill. TRUTH: HYPOTHERMIA (<35.5°C) in a young infant is a DANGER SIGN just as much as fever — young infants with infection may be hypothermic, not febrile.

Common Exam Questions

Example

A 10-month-old child has a respiratory rate of 52 breaths per minute. The nurse classifies this as: A) Normal B) Fast breathing C) Borderline D) Severe chest indrawing — Answer: B (≥50/min for 2–12 months)

Approach

Memorise the three age-based cut-offs exactly. The NLE will give an age and a respiratory rate and ask whether it is fast breathing. Apply the correct threshold for the age group.

Question Type

Respiratory rate threshold identification

Example

A 2-year-old child is lethargic and unable to drink during assessment. The nurse classifies this child as: A) GREEN — home management B) YELLOW — treat at facility C) PINK — urgent referral D) BLUE — palliative — Answer: C (Lethargic = general danger sign = PINK)

Approach

IMCI colour-code is directly tested. PINK = refer, YELLOW = treat at facility, GREEN = home care. Any general danger sign = PINK. Chest indrawing = PINK (severe pneumonia). Fast breathing only = YELLOW (non-severe pneumonia).

Question Type

Classification by colour code

Example

A 1-month-old infant has a temperature of 38.2°C, fast breathing, and is moving only when stimulated. The nurse should: A) Give paracetamol and observe B) Initiate urgent referral C) Begin Plan B oral rehydration D) Give Vitamin A supplementation — Answer: B

Approach

Know the young infant (1 week–2 months) danger signs by heart. These are different from older children and the NLE tests them separately. Temperature thresholds: fever ≥37.5°C and hypothermia <35.5°C are both danger signs in young infants.

Question Type

Young infant danger sign identification

Key Points To Remember

IMCI: Assess → Classify (PINK/YELLOW/GREEN) → Treat → Counsel → Follow up
GENERAL DANGER SIGNS (any 1 = PINK = URGENT REFER): can't drink/breastfeed, vomits everything, convulsions, lethargic/unconscious
PINK = Urgent referral; YELLOW = Treat at facility + home care; GREEN = Home management
Fast-breathing cut-offs: <2 months ≥60/min; 2–12 months ≥50/min; 12 months–5 years ≥40/min
CHEST INDRAWING = Severe pneumonia → PINK = Urgent referral
No chest indrawing, only fast breathing = Non-severe pneumonia → YELLOW = Oral amoxicillin
Young infant danger signs: not feeding, fast breathing ≥60, temp <35.5 or ≥37.5°C, convulsions, no movement
Always check immunisation status and counsel on feeding in every IMCI visit
Count respirations for ONE FULL MINUTE for accuracy
Two IMCI charts: Young Infant (1 wk–2 mo) and Sick Child (2 mo–5 yr)

DOH Programs — EPI and Garantisadong Pambata (GP)

Two major Philippine DOH programs form the backbone of childhood communicable disease prevention and must be thoroughly known for the NLE. EXPANDED PROGRAM ON IMMUNIZATION (EPI): The Philippine EPI provides FREE vaccines to all Filipino children. The current EPI schedule includes: - BIRTH: BCG (tuberculosis prevention) + Hepatitis B (first dose — within 12–24 hours of birth ideally) - 6 WEEKS (1.5 months): Pentavalent vaccine (DPT-Hib-HepB) + Oral Polio Vaccine (OPV) + Pneumococcal Conjugate Vaccine (PCV) — 1st dose - 10 WEEKS (2.5 months): Pentavalent + OPV + PCV — 2nd dose - 14 WEEKS (3.5 months): Pentavalent + OPV + PCV — 3rd dose; INACTIVATED Polio Vaccine (IPV) — 1 dose - 9 MONTHS: Measles-Containing Vaccine 1 (MCV1) — first measles/MMR dose - 12–15 MONTHS: MMR (Measles-Mumps-Rubella) — MCV2 (second dose) Note: Rotavirus vaccine has been included in some expanded EPI programmes. GARANTISADONG PAMBATA (GP) — 'Guaranteed for Children': GP is a BIANNUAL (twice yearly — typically held in January and July) child health package delivered by the DOH, usually at the barangay level. It provides: 1. VITAMIN A SUPPLEMENTATION: - Infants 6–11 months: 100,000 IU — ONCE - Children 12–59 months (1–5 years): 200,000 IU — EVERY 6 MONTHS 2. DEWORMING (for children 1–5 years) — mebendazole or albendazole, twice yearly 3. IMMUNISATION CATCH-UP — for children with missed vaccines 4. GROWTH MONITORING — weighing and plotting on growth charts 5. HEALTH EDUCATION for mothers and caregivers VITAMIN A SUPPLEMENTATION IN MEASLES: Vitamin A is also given specifically in MEASLES regardless of the GP schedule: - <6 months: 50,000 IU on Day 1 and Day 2 - 6–11 months: 100,000 IU on Day 1 and Day 2 - ≥12 months and older: 200,000 IU on Day 1 and Day 2 Vitamin A deficiency worsens measles severity, increases pneumonia risk, and contributes to measles mortality — hence the WHO/DOH recommendation to supplement ALL children with measles. The community nurse's role in EPI and GP includes: administering vaccines correctly (route, dose, site, cold chain maintenance), educating parents, recording and tracking immunisation status, conducting outreach activities, and integrating GP with IMCI during well-child visits.

Examples

The GP biannual activity is an opportunity to reach children who missed earlier vaccines. The nurse integrates catch-up immunisation with Vitamin A supplementation and growth monitoring.

Scenario

During a Garantisadong Pambata activity in January at the barangay health centre, a mother presents her 18-month-old child who has never received Vitamin A supplementation and missed the measles vaccine at 9 months.

Solution

The nurse should: (1) Administer VITAMIN A 200,000 IU (child is 12–59 months) — this is the GP dose; (2) Administer MCV1 (measles-containing vaccine) — give the missed dose now as catch-up; (3) Update the child's immunisation card; (4) Counsel the mother to return in 6 months (July GP activity) for the next Vitamin A dose and immunisation check; (5) Record in the barangay immunisation register.

Applications

Know the complete EPI schedule by heart — the NLE tests which vaccine is given at which age
Maintain cold chain: most vaccines are stored at +2 to +8°C; OPV at -15 to -25°C
Administer Vitamin A doses correctly based on age (GP vs. measles-specific dosing)
Record all immunisations in the mother-child health book and the health centre's immunisation register
Conduct GP biannual activities in January and July — coordinate with the barangay
During IMCI visits, always CHECK and UPDATE the child's immunisation status
Educate mothers on the importance of completing all doses — incomplete vaccination leaves children susceptible

Misconceptions

MISCONCEPTION: The MMR vaccine is given at 9 months. TRUTH: MCV1 (measles-only or measles-containing) is at 9 months; MMR (measles-mumps-rubella) is at 12–15 months.
MISCONCEPTION: Garantisadong Pambata is conducted once a year. TRUTH: GP is BIANNUAL — conducted TWICE a year (January and July).
MISCONCEPTION: Vitamin A in the GP is the same dose for all children. TRUTH: 6–11 months = 100,000 IU; 12–59 months = 200,000 IU — different doses for different age groups.
MISCONCEPTION: All EPI vaccines are stored at the same temperature. TRUTH: OPV is stored frozen (-15 to -25°C); all other EPI vaccines are stored refrigerated (+2 to +8°C).

Common Exam Questions

Example

A 2-year-old child attends the January Garantisadong Pambata activity. The nurse administers: A) 100,000 IU Vitamin A B) 200,000 IU Vitamin A C) 50,000 IU Vitamin A D) No Vitamin A — Answer: B

Approach

The NLE will state a child's age and ask for the correct GP Vitamin A dose. Memorise: 6–11 months = 100,000 IU once; 12–59 months = 200,000 IU every 6 months. Also memorise the measles-specific doses.

Question Type

Vitamin A dose identification

Example

A 9-month-old child visits the health centre for immunisation. The nurse administers: A) BCG B) Pentavalent 1st dose C) Measles-containing vaccine (MCV1) D) MMR — Answer: C

Approach

Know which vaccines are given at birth, 6 weeks, 10 weeks, 14 weeks, 9 months, and 12–15 months. The NLE tests these frequently in vignette format.

Question Type

Measles Vitamin A: 50,000 IU (<6 mo), 100,000 IU (6–11 mo), 200,000 IU (≥12 mo) — Days 1 and 2
COLD CHAIN must be maintained for vaccines — store at 2–8°C (except OPV at -15 to -25°C)
The nurse records all immunisations in the child's health card (Immunization Card)

Practice Problems

The Koplik spots + 3 C's + high fever = classic prodromal measles. Measles is transmitted via the AIRBORNE route — the most important nursing action is preventing nosocomial transmission to other patients and staff. Vitamin A is the disease-specific supplementation for ALL children with measles, regardless of nutritional status, given to reduce severity and mortality. Dim the room for photophobia and monitor for pneumonia (most common cause of death).

Problem

A 6-year-old child is admitted to the paediatric ward with high fever (39.8°C), runny nose, red watery eyes, and cough for 4 days. On inspection of the buccal mucosa, the nurse notes tiny white spots on a red base inside the cheeks. The attending physician expects a rash to appear within 1–2 days. What is the PRIORITY nursing intervention, and which specific supplementation must the nurse prepare?

Solution

PRIORITY INTERVENTION: Implement AIRBORNE PRECAUTIONS immediately (N95 respirator, private room with negative pressure or closed door, limit visitors). SPECIFIC SUPPLEMENTATION: Prepare VITAMIN A. For a 6-year-old (≥12 months): 200,000 IU on Day 1 and Day 2.

The IMCI dehydration classification requires careful assessment of ALL four signs simultaneously. 'Drinks eagerly' indicates the child is thirsty — a sign of SOME dehydration. Plan B means supervised ORS at 75 mL/kg over 4 hours. Zinc supplementation for ≥6 months is 20 mg/day for the full 10–14 days. The nurse must teach the mother how to give ORS by spoon and when to return immediately.

Problem

The nurse is conducting an IMCI assessment at the Rural Health Unit. A mother brings her 8-month-old infant who has had diarrhoea for 2 days. Assessment findings: alert and responsive; eyes appear normal; skin returns to normal position immediately when pinched; drinking eagerly when offered ORS. How should the nurse classify this child, and what is the treatment plan?

Solution

CLASSIFICATION: SOME DEHYDRATION (YELLOW). Rationale: The child has 2 signs: 'Drinks eagerly' (eager for fluids = thirsty = dehydrated) + restlessness OR alternatively 'drinks eagerly' alone suggests some dehydration. Wait — reassess: eyes normal + skin turgor normal suggests NO dehydration; but 'drinks eagerly' is a sign of SOME dehydration. Correct classification with 'drinks eagerly' as one sign plus any other = SOME DEHYDRATION. If only 1 sign: reassess. In this case, treat as PLAN B cautiously or Plan A depending on full context. Applying Plan B (some dehydration confirmed): ORS 75 mL/kg over 4 hours under facility supervision. For 8 kg infant: 8 × 75 = 600 mL ORS over 4 hours = 150 mL per hour. ZINC: 20 mg/day for 10–14 days (child is ≥6 months). Continue breastfeeding/feeding. Reassess after 4 hours. Counsel on warning signs.

The critical phase of dengue occurs when the FEVER DROPS (defervescence) around Days 4–6. This is when plasma leakage is most active. Restlessness + severe abdominal pain + temperature drop = dengue warning signs requiring URGENT action. The positive tourniquet test and low platelets support the dengue diagnosis. Fluid management is the cornerstone of dengue treatment — IV fluids are needed if the child cannot tolerate oral fluids or is in early shock.

Problem

A 3-year-old child is brought to the BHU with high fever for 5 days, severe headache, pain behind the eyes, and a red rash on the body. The nurse performs the tourniquet test and counts 12 petechiae in the 1-inch square area. The platelet count done yesterday was 95,000/mm³. Today, the child's temperature has dropped to 37.0°C, but the mother says the child is restless and the abdomen is very painful. What are the dengue warning signs present, and what is the priority nursing action?

Solution

WARNING SIGNS PRESENT: (1) Severe abdominal pain; (2) Restlessness; (3) Rapid drop in temperature (defervescence during critical phase). Additionally: Positive tourniquet test (≥10 petechiae = positive); Thrombocytopaenia (platelets 95,000 = low and may be dropping). PRIORITY NURSING ACTION: IMMEDIATELY notify the physician — the child is in the CRITICAL PHASE of dengue and showing warning signs of progression to dengue haemorrhagic fever or dengue shock syndrome. Prepare for IV fluid resuscitation; assess vital signs (BP, pulse pressure, capillary refill); establish IV access; monitor urine output; DO NOT give aspirin or NSAIDs — use paracetamol only.

Young infants under 2 months are assessed using the YOUNG INFANT IMCI chart. FOUR danger signs are present simultaneously — any single danger sign mandates urgent referral. Hypothermia in a young infant is as serious as fever. The nurse's pre-referral priority is MAINTAINING WARMTH (skin-to-skin), ensuring the airway is clear, and giving the first dose of antibiotics before transport. The 'keep warm' instruction is critical — young infants cannot regulate body temperature and hypothermia worsens prognosis during transport.

Problem

During an IMCI assessment, a nurse sees a 6-week-old infant brought by the mother because 'the baby is not feeding well and feels cold.' Vital signs: temperature 35.2°C, RR 65 breaths/min, PR 160 bpm. The baby moves sluggishly and only when stimulated. There is no yellow discolouration of the skin or eyes. How does the nurse classify this infant and what pre-referral actions should be taken?

Solution

CLASSIFICATION: POSSIBLE SERIOUS BACTERIAL INFECTION / VERY SEVERE DISEASE — PINK (URGENT REFERRAL). Young infant danger signs present: (1) Not feeding well; (2) Low body temperature 35.2°C (<35.5°C = hypothermia); (3) Fast breathing ≥60/min (RR 65); (4) Movement only when stimulated. ANY ONE of these = urgent referral. PRE-REFERRAL ACTIONS: (1) KEEP WARM — skin-to-skin kangaroo care, wrap in warm blanket; (2) Ensure airway is clear; (3) If able to swallow, give expressed breastmilk or ORS to prevent hypoglycaemia; (4) Administer first dose of IM antibiotics as prescribed; (5) Prepare for URGENT TRANSPORT to hospital; (6) Accompany/ensure the mother keeps the baby warm during transport; (7) Write a referral note for the receiving facility.

All three answers involve high-yield NLE concepts: (1) Aspirin contraindication in varicella → Reye's syndrome; (2) Infectivity until ALL lesions crust — not 'most'; (3) Varicella in pregnancy — peripartum varicella poses severe risk to the neonate (different from congenital varicella syndrome which is first trimester). The nurse must give clear, specific advice to protect both the child and vulnerable contacts.

Problem

A nurse is counselling a mother whose 7-year-old child has been diagnosed with varicella (chickenpox). The child has had lesions for 4 days. Most lesions are crusted, but 5 vesicles on the chest and arms still contain clear fluid. The mother asks: (1) Can I give aspirin for the fever? (2) Can my child go back to school tomorrow? (3) My neighbour is 7 months pregnant — can she visit? Answer all three questions with rationale.

Solution

(1) NO — aspirin is ABSOLUTELY CONTRAINDICATED in children with varicella. Give PARACETAMOL instead. Aspirin in viral illness in children causes REYE'S SYNDROME — a life-threatening encephalopathy with fatty liver degeneration. (2) NO — the child cannot return to school until ALL lesions are crusted over (dry scabs). Even 5 active vesicles mean the child is still CONTAGIOUS via both airborne route (respiratory droplets) and direct contact with vesicle fluid. (3) The nurse should STRONGLY ADVISE against the pregnant neighbour visiting. A woman in the third trimester of pregnancy who contracts varicella risks severe varicella pneumonia for herself, and the fetus risks NEONATAL VARICELLA (peripartum infection) which can be fatal to the newborn if delivery occurs within 5 days before to 2 days after maternal rash onset.

Exam Preparation Tips

MEMORISE THE TRANSMISSION ROUTES as your first anchor: Airborne = Measles, Varicella; Droplet = Mumps, Rubella, Pertussis, Diphtheria; Vector (Aedes aegypti) = Dengue. The NLE frequently asks about precautions, and the precaution depends on the route.
LEARN THE HALLMARK SIGNS as a rapid trigger: Koplik spots = Measles; Postauricular nodes = Rubella; Parotid swelling = Mumps; 'Dewdrops on rose petal' vesicles in crops = Varicella; Grey pseudomembrane = Diphtheria; Inspiratory whoop = Pertussis; Retro-orbital pain + positive tourniquet test = Dengue.
MEMORISE THE 3 DRUG CONTRAINDICATIONS that the NLE tests repeatedly: (1) NO ASPIRIN in varicella (Reye's syndrome); (2) NO ASPIRIN/NSAIDs in dengue (bleeding risk); (3) NEVER REMOVE the diphtheria pseudomembrane (bleeding/obstruction).
IMCI FAST-BREATHING CUT-OFFS — use a simple mnemonic: '6-5-4 rule': Less than 2 months = 60, 2–12 months = 50, 12 months–5 years = 40 breaths per minute.
MEMORISE THE GENERAL DANGER SIGNS of IMCI by the mnemonic 'VCVL': Vomits everything, Convulsions, can't drink/breastfeed (V = very unable to drink), Lethargic/unconscious. ANY ONE = PINK = URGENT REFERRAL.
ZINC DOSES: Create a simple two-point rule — under 6 months = 10 mg; 6 months and above = 20 mg — BOTH for 10–14 days. This is tested in scenario questions about diarrhoea management.
DEHYDRATION PLANS: Think in numbers — Plan A = home; Plan B = 75 mL/kg over 4 hours at the facility; Plan C = IV fluids. If you can drink = A or B; if you cannot drink at all = C.
COMPLICATION LINKAGES to memorise for NLE: Measles → Pneumonia (most common death); Mumps → Orchitis (post-pubertal males); Varicella → Reye's syndrome if aspirin given; Rubella → Congenital Rubella Syndrome (CRS); Diphtheria → Myocarditis; Pertussis → Apnea in infants; Dengue → Dengue Shock Syndrome.
GARANTISADONG PAMBATA: Biannual (January and July). Vitamin A doses: 6–11 months = 100,000 IU once; 12–59 months = 200,000 IU every 6 months. This is a favourite NLE dosage calculation question.
DENGUE CRITICAL PHASE TRAP: When the fever DROPS (defervescence, Days 4–6), that is when the patient is MOST AT RISK — not recovering. Teach this to prevent missing the warning signs during the critical phase.
RUBELLA PRIORITY QUESTION RULE: Whenever a rubella scenario includes a pregnant person, the PRIORITY nursing action is ALWAYS to separate/protect the pregnant person — this supersedes all other interventions.
PRACTICE IMCI CLASSIFICATION QUESTIONS: The NLE gives a clinical vignette and asks for the colour classification. Identify: General danger signs first (PINK), then assess each symptom for severity (PINK or YELLOW or GREEN). Practise until classification becomes automatic.
STUDY THE EPI SCHEDULE AS A TABLE: Create a flashcard with ages on one side and vaccines on the other. Know that BCG + HepB = birth; pentavalent + OPV + PCV = 6/10/14 weeks; MCV1 = 9 months; MMR = 12–15 months.
FOR PERTUSSIS: The ANTIBIOTIC answer is always MACROLIDE (erythromycin, azithromycin, or clarithromycin). NOT penicillin. NOT amoxicillin. NOT tetracycline (contraindicated in children).
FOR DIPHTHERIA: The SPECIFIC TREATMENT is DIPHTHERIA ANTITOXIN (DAT) — not the antibiotic. Antibiotics kill bacteria; antitoxin neutralises the toxin. Always give antitoxin first (after skin test). Do a skin test before DAT administration because it is derived from horse serum.
