Midwife Licensure Exam Infant & Child Health (Growth, Development & IMCI)Communicable & Infectious Diseases in Children (IMCI)Revision Notes

Condensed revision notes for Communicable & Infectious Diseases in Children (IMCI), built for the final weeks before the Midwife Licensure Exam 2026. These are the distilled key points you need when there is no time left for full study notes — just the concepts, formulas, and traps Professional Regulation Commission (PRC) — Board of Midwifery tests.

Exam context

For the Midwife Licensure Examination, Professional Regulation Commission (PRC) — Board of Midwifery tests Infant & Child Health (Growth, Development & IMCI) under a "Core" label, with Communicable & Infectious Diseases in Children (IMCI) in the 6th slot across 6 chapters. Midwife Licensure Exam candidates must clear the 75% weighted average cut on the 2026 paper, which draws about a meaningful share of Infant & Child Health (Growth, Development & IMCI) questions. Date to watch: April and November 2026 (expected).

Communicable & Infectious Diseases in Children (IMCI) - Revision Notes

Communicable diseases are among the leading causes of under-5 morbidity and mortality in the Philippines. As a future registered nurse (RN) under RA 9173, you are expected to accurately assess, classify, and manage sick children at the community and hospital level. This chapter covers the classic childhood exanthems (measles, mumps, varicella, rubella, pertussis, diphtheria), dengue, diarrhoeal disease, and the WHO/DOH Integrated Management of Childhood Illness (IMCI) framework — all heavily tested areas in the NLE. Mastery of hallmark signs, isolation precautions, complications, and nursing management is essential for safe, effective pediatric nursing practice.

Sections

Exam Tips

  • Make a quick mental table: Disease → Transmission → Hallmark → Main complication → Key nursing action.
  • If the question mentions 'pathognomonic' or 'hallmark,' think: Measles = Koplik spots; Diphtheria = pseudomembrane; Pertussis = inspiratory whoop; Dengue = tourniquet test.
  • Questions about isolation: identify the transmission route FIRST, then choose the correct precaution level.
  • Any child who is lethargic, unconscious, convulsing, vomiting everything, or unable to drink = URGENT REFERRAL under IMCI (Pink classification).

Key Points

  • Most classic childhood communicable diseases are vaccine-preventable through the DOH Expanded Program on Immunization (EPI).
  • The THREE most important items to know for each disease: (1) causative agent and MODE OF TRANSMISSION, (2) hallmark/pathognomonic sign, and (3) main complication.
  • Isolation precautions follow transmission route: AIRBORNE (measles, varicella) requires N95 mask and negative-pressure room; DROPLET (mumps, rubella, pertussis, diphtheria) requires surgical mask and 1-meter distance; CONTACT (varicella — also) requires gloves and gown.
  • The nursing process guides all management: ASSESS (signs/symptoms, vitals, hydration, rash, lymph nodes), DIAGNOSE (NANDA), PLAN, IMPLEMENT, EVALUATE.
  • Priority nursing diagnoses across communicable diseases include: Hyperthermia (Maslow physiologic), Risk for Infection Transmission, Impaired Skin Integrity (varicella), Ineffective Airway Clearance (pertussis, diphtheria), and Deficient Fluid Volume (dengue, diarrhoea).
  • Under RA 9173 (Philippine Nursing Act of 2002), the RN has the legal authority to assess, plan, implement, and evaluate nursing care — including initiating isolation precautions and health education independently.

Definitions

Term

Exanthem

Definition

A skin rash that appears as a symptom of a systemic (body-wide) infectious disease, such as the rash in measles or chickenpox.

Importance

Recognizing the type and progression of a rash is key to differential diagnosis in the NLE.

Term

Pathognomonic Sign

Definition

A sign or symptom that is so specific to a disease that its presence alone confirms the diagnosis.

Importance

NLE questions frequently ask for the hallmark or pathognomonic sign of each childhood disease — memorize these.

Term

Isolation Precautions

Definition

Infection control measures used to prevent the spread of communicable diseases, classified as airborne, droplet, or contact precautions based on the mode of transmission.

Importance

A common NLE question stem asks which type of isolation room or PPE to prepare — always base your answer on the route of transmission.

Term

Cephalocaudal Rash Spread

Definition

A rash pattern that begins on the head/face and spreads downward toward the feet, characteristic of measles.

Importance

Distinguishes measles rash from other childhood rashes — tested frequently in NLE.

Section Title

Overview: Key Concepts in Childhood Communicable Diseases

Common Mistakes

  • Confusing AIRBORNE vs. DROPLET precautions — measles and varicella are AIRBORNE (N95 required); mumps, rubella, pertussis, diphtheria are DROPLET.
  • Forgetting that varicella requires BOTH airborne AND contact precautions.
  • Mixing up which disease's complication is orchitis (mumps) vs. myocarditis (diphtheria) vs. encephalitis (measles).
  • Giving aspirin for fever in varicella — this causes REYE'S SYNDROME; always use paracetamol.

Exam Tips

  • Memory aid: 'KOPLIK SPOTS COME BEFORE KOPLIK STOPS' — they appear before the rash and stop when the rash begins.
  • If a question asks 'Which sign is PATHOGNOMONIC for measles?' — always answer KOPLIK SPOTS.
  • Vitamin A is given in measles to reduce blindness and pneumonia risk — this is a WHO/DOH-recommended nursing action.
  • Rash direction: CEPHALOCAUDAL = top to bottom = measles. This distinguishes it from other rashes.

Key Points

  • Causative agent: Measles virus. Transmission: AIRBORNE — the most contagious of all childhood diseases.
  • Incubation period: 10–14 days. Infectious period: from 4 days BEFORE to 4 days AFTER rash onset.
  • PRODROMAL PHASE (3–4 days): High fever, the '3 C's' — Cough, Coryza (runny nose), and Conjunctivitis — plus photophobia.
  • PATHOGNOMONIC SIGN: KOPLIK SPOTS — tiny bluish-white spots on a red base found on the BUCCAL MUCOSA (inner cheek). They appear BEFORE the rash and disappear as the rash emerges.
  • RASH: Erythematous (red) maculopapular, begins at the HAIRLINE/FACE and spreads CEPHALOCAUDALLY (downward). Fades in the same order (brownish discoloration, then desquamation).
  • Complications: PNEUMONIA (most common cause of measles death in children), otitis media, encephalitis, blindness.
  • Management: Supportive — adequate fluids, paracetamol for fever, dim room for photophobia. GIVE VITAMIN A to ALL children with measles (reduces severity and mortality). AIRBORNE precautions.
  • Vitamin A dose in measles: 50,000 IU (<6 months), 100,000 IU (6–11 months), 200,000 IU (≥12 months) — given for 2 consecutive days.
  • Prevention: MMR (Measles-Mumps-Rubella) vaccine — given at 9 months and 12–15 months per EPI schedule.

Definitions

Term

Koplik Spots

Definition

Tiny bluish-white spots on a reddish base, found on the buccal mucosa (inner cheek lining), appearing 1–2 days BEFORE the measles rash. They are PATHOGNOMONIC for measles.

Importance

The single most-tested sign of measles on the NLE — know that they appear BEFORE the rash.

Term

The 3 C's of Measles

Definition

Cough, Coryza (runny nose), and Conjunctivitis — the classic triad of the prodromal phase of measles, occurring before the rash.

Importance

A question describing these three symptoms with high fever in a child likely refers to measles — high-yield NLE pattern.

Section Title

Measles (Rubeola)

Common Mistakes

  • Saying Koplik spots appear WITH or AFTER the rash — they appear BEFORE and disappear as rash emerges.
  • Giving the wrong dose of Vitamin A for the child's age group during measles management.
  • Forgetting that PNEUMONIA (not encephalitis) is the most common cause of death in measles.
  • Using contact-only precautions — measles requires AIRBORNE precautions (N95 mask, negative-pressure room).

Exam Tips

  • Memory aid for mumps diet: 'No sour, no salty — keep it bland and soft.'
  • If the question mentions a teenage boy with mumps developing testicular pain → orchitis → risk for infertility.
  • Mumps = DROPLET (surgical mask, 1-meter distance) — NOT airborne.

Key Points

  • Causative agent: Mumps virus. Transmission: DROPLET. Incubation: 14–21 days.
  • HALLMARK: Painful, tender swelling of the PAROTID GLANDS (salivary glands just below and in front of the ears), bilateral in most cases — giving a 'chipmunk' facial appearance.
  • Symptoms: Fever, earache, pain on chewing and swallowing (especially with sour/acidic foods which stimulate saliva flow).
  • Complications: ORCHITIS (testicular inflammation — can cause infertility in post-pubertal males), oophoritis (in females), aseptic meningitis, encephalitis, sensorineural DEAFNESS.
  • Management: Supportive — analgesics/antipyretics (paracetamol/ibuprofen), soft BLAND diet, AVOID SOUR/ACIDIC foods (triggers pain), warm or cool compresses to parotid area. SCROTAL SUPPORT if orchitis develops. DROPLET precautions.
  • Prevention: MMR vaccine.

Definitions

Term

Parotitis

Definition

Inflammation and swelling of the parotid (salivary) glands, the hallmark of mumps, causing facial swelling just in front of and below the ears.

Importance

The physical appearance of parotid swelling is the classic NLE image-based question on mumps.

Term

Orchitis

Definition

Inflammation of one or both testes, a complication of mumps in post-pubertal males, which may lead to infertility if bilateral.

Importance

The most feared complication of mumps in adolescent/adult males — a common NLE distractor question.

Section Title

Mumps (Epidemic Parotitis)

Common Mistakes

  • Giving sour foods or juices (like orange juice) to a child with mumps — this stimulates saliva and WORSENS pain.
  • Forgetting to apply scrotal support for orchitis — important comfort nursing measure.
  • Confusing mumps complications with measles complications — orchitis = mumps; pneumonia = measles; myocarditis = diphtheria.

Exam Tips

  • Key phrase: 'All stages at once' = varicella. This is the single most important differentiating feature.
  • 'Dewdrops on a rose petal' = varicella vesicles on an erythematous base — a classic NLE descriptor.
  • Reye's syndrome prevention = NO ASPIRIN in children with ANY viral illness, especially varicella or influenza.
  • Isolation is lifted only when ALL lesions are crusted — not when new lesions stop appearing.

Key Points

  • Causative agent: Varicella-Zoster Virus (VZV). Transmission: AIRBORNE + DIRECT CONTACT with vesicle fluid. Incubation: 10–21 days.
  • HALLMARK: Pruritic (very itchy) vesicular rash appearing in 'CROPS' — meaning lesions are present in ALL stages simultaneously: macule → papule → vesicle → crust. Vesicles are described as 'dewdrops on a rose petal.'
  • The rash starts on the TRUNK (face, scalp, trunk) and spreads CENTRIFUGALLY (outward) to extremities — opposite pattern from measles.
  • CONTAGIOUS PERIOD: From 1–2 days BEFORE rash until ALL lesions have CRUSTED OVER (no more weeping vesicles).
  • Management: Symptomatic relief — CALAMINE LOTION (soothes itch), ANTIHISTAMINES (oral), COOL BATHS, KEEP NAILS SHORT (prevent scratching → secondary bacterial infection). ACYCLOVIR for immunocompromised/high-risk children. AIRBORNE + CONTACT precautions.
  • CRITICAL: NEVER GIVE ASPIRIN to children with varicella — causes REYE'S SYNDROME (acute encephalopathy and liver failure). Use PARACETAMOL.
  • Prevention: Varicella vaccine (Varivax) — 2 doses.

Definitions

Term

Crops of Lesions

Definition

The characteristic rash pattern of varicella where new lesions appear in waves (crops), so at any given time, lesions in ALL stages (macule, papule, vesicle, crust) are present on the body simultaneously.

Importance

This is the pathognomonic feature of varicella — distinguishes it from smallpox (all lesions same stage) and other rashes.

Term

Reye's Syndrome

Definition

A rare but serious condition causing brain swelling (encephalopathy) and liver damage, associated with aspirin use during viral illnesses like varicella or influenza in children.

Importance

A critical safety point — always use paracetamol, NEVER aspirin, in children with varicella. Commonly tested on the NLE.

Section Title

Varicella (Chickenpox)

Common Mistakes

  • Giving aspirin for fever in a child with varicella — this is a SERIOUS MEDICATION ERROR leading to Reye's syndrome.
  • Discharging the child before ALL lesions have crusted — the child remains contagious until complete crusting.
  • Using only CONTACT precautions — varicella requires BOTH AIRBORNE and CONTACT precautions.
  • Forgetting to keep fingernails short — scratching breaks vesicles, causing secondary bacterial infection (impetigo).

Exam Tips

  • Memory aid: 'Rubella = 3 days, Mild, but Menace to the Mother's baby.'
  • If a question mentions a pregnant nurse exposed to a child with rubella — the concern is CRS in the fetus.
  • Postauricular lymphadenopathy + 3-day rash + low-grade fever = RUBELLA (not measles).
  • MMR vaccine protects against all three: Measles, Mumps, Rubella — given at 9 months and 12–15 months per EPI.

Key Points

  • Causative agent: Rubella virus. Transmission: DROPLET. Incubation: 14–21 days. Generally MILD in children.
  • HALLMARK: A pink maculopapular rash starting on the FACE, spreading downward — lasts only ~3 days (hence '3-day measles'). Accompanied by LOW-GRADE FEVER.
  • DISTINCTIVE SIGN: POSTAURICULAR (behind the ears), OCCIPITAL (back of head), and POSTERIOR CERVICAL LYMPHADENOPATHY — tender lymph nodes in these areas, appearing BEFORE the rash.
  • GREATEST DANGER: NOT to the infected child, but to the FETUS. Rubella in a pregnant woman (especially first trimester) causes CONGENITAL RUBELLA SYNDROME (CRS): cataracts, congenital heart defects (PDA, VSD), sensorineural deafness, intellectual disability ('CCHD' triad).
  • Nursing action: KEEP INFECTED CHILDREN AWAY FROM PREGNANT WOMEN. Report to local health authority (communicable disease is reportable).
  • Management: Supportive — analgesics, fluids, rest. DROPLET precautions.
  • Prevention: MMR vaccine — the most important intervention.

Definitions

Term

Congenital Rubella Syndrome (CRS)

Definition

A set of birth defects caused by the rubella virus crossing the placenta during the first trimester of pregnancy, resulting in cataracts, congenital heart defects, deafness, and intellectual disability in the newborn.

Importance

The primary reason rubella is a public health concern — the child's illness is mild, but the fetal consequence is devastating. A high-yield NLE topic.

Term

Postauricular Lymphadenopathy

Definition

Swelling of lymph nodes located BEHIND the ears (postauricular) and at the back of the head (occipital), a characteristic finding in rubella that appears BEFORE the rash.

Importance

Distinguishes rubella from measles and other exanthems — an NLE differentiator.

Section Title

Rubella (German Measles / 3-Day Measles)

Common Mistakes

  • Thinking rubella is dangerous for the CHILD — it is MILD in children; the danger is to the FETUS of a pregnant contact.
  • Confusing rubella (3-day mild rash + postauricular nodes) with measles (3 C's + Koplik spots + pneumonia risk).
  • Forgetting to segregate rubella-infected children from pregnant women — a critical nursing responsibility.

Exam Tips

  • Pertussis drug of choice: MACROLIDE (erythromycin/azithromycin) — NOT penicillin, NOT cephalosporins.
  • Infant + apnea + cough = suspect pertussis — hospitalize immediately and monitor respirations.
  • The 'whoop' is caused by the forced inhalation after prolonged expiratory coughing — the airway is briefly obstructed by thick mucus.
  • Pertussis = DROPLET precautions = surgical mask + 1-meter distance + hand hygiene.

Key Points

  • Causative agent: Bordetella pertussis (bacteria). Transmission: DROPLET. Incubation: 6–20 days.
  • THREE STAGES: (1) CATARRHAL stage (1–2 wks) — resembles URI, runny nose, mild cough, most contagious; (2) PAROXYSMAL stage (2–4 wks) — HALLMARK: severe coughing paroxysms ending with a high-pitched inspiratory 'WHOOP,' followed by post-tussive vomiting and cyanosis; (3) CONVALESCENT stage — gradual recovery.
  • Most DANGEROUS in YOUNG INFANTS (< 6 months) — instead of a 'whoop,' infants may have APNEA (life-threatening cessation of breathing). Requires hospitalization and monitoring.
  • Complications: Pneumonia (most common), apnea, seizures (from hypoxia), subconjunctival hemorrhage (from coughing pressure).
  • Management: MACROLIDE ANTIBIOTICS — erythromycin, azithromycin, or clarithromycin (antibiotic of choice). Supportive: gentle suctioning, supplemental oxygen, small frequent feeds, hydration, APNEA MONITORING for infants. DROPLET precautions.
  • Prevention: DPT/Pentavalent vaccine (given at 6, 10, 14 weeks per EPI). Tdap booster for caregivers (cocooning strategy).

Definitions

Term

Inspiratory Whoop

Definition

The characteristic high-pitched crowing sound produced when a child gasps for air after a prolonged coughing paroxysm in pertussis, caused by turbulent airflow through a narrowed airway.

Importance

The pathognomonic sound of pertussis — if a question describes 'barking cough followed by a high-pitched inspiratory sound,' the answer is pertussis.

Term

Post-tussive Vomiting

Definition

Vomiting that occurs immediately after a coughing paroxysm, a classic finding in pertussis, due to the force of coughing stimulating the gag reflex.

Importance

Triad of pertussis: coughing paroxysm + inspiratory whoop + post-tussive vomiting.

Section Title

Pertussis (Whooping Cough)

Common Mistakes

  • Forgetting that young infants may NOT produce the 'whoop' — instead presenting with APNEA, making pertussis harder to recognize in this age group.
  • Using penicillin instead of macrolides — the drug of choice is ERYTHROMYCIN or AZITHROMYCIN (macrolide class).
  • Administering large feeds — should be SMALL, FREQUENT FEEDS to reduce post-tussive vomiting and aspiration risk.

Exam Tips

  • Priority nursing action in diphtheria: Give ANTITOXIN first (neutralize toxin), then antibiotics (eliminate bacteria).
  • Complication to always monitor: MYOCARDITIS — watch for dysrhythmias, chest pain, poor pulse quality.
  • Airway emergency: Have tracheostomy set at bedside for possible airway obstruction from pseudomembrane extension.
  • Strict bed rest rationale: Prevents increased cardiac demand in a heart already compromised by the toxin.

Key Points

  • Causative agent: Corynebacterium diphtheriae (bacteria, produces exotoxin). Transmission: DROPLET. Incubation: 2–5 days.
  • HALLMARK: A tough, adherent, GREYISH-WHITE PSEUDOMEMBRANE over the tonsils and pharynx that BLEEDS when removed — DO NOT attempt to forcibly remove it (causes bleeding and spreads toxin).
  • Clinical features: Sore throat, LOW-GRADE FEVER, 'BULL NECK' appearance (from cervical lymphadenopathy and edema), hoarseness, and possible stridor (airway obstruction).
  • COMPLICATIONS: (1) AIRWAY OBSTRUCTION (from membrane extension to larynx/trachea) — have emergency airway equipment ready; (2) MYOCARDITIS (cardiac toxicity from diphtheria exotoxin — leading cause of death); (3) Neuritis (peripheral nerve damage).
  • Management: (1) DIPHTHERIA ANTITOXIN (DAT) — neutralizes unbound toxin, given IMMEDIATELY regardless of culture results; (2) ANTIBIOTICS — penicillin or erythromycin (to eliminate the bacteria); (3) STRICT BED REST (to reduce cardiac workload — myocarditis risk); (4) Keep emergency airway equipment (tracheostomy set) at bedside; (5) DROPLET precautions.
  • Prevention: DPT/Pentavalent vaccine.

Definitions

Term

Pseudomembrane

Definition

A thick, tough, greyish-white fibrinous membrane that forms over the tonsils, pharynx, and possibly the larynx in diphtheria. It bleeds when forcibly removed and can extend to obstruct the airway.

Importance

The hallmark of diphtheria — if a question describes a 'grey membrane over the throat,' the answer is diphtheria.

Term

Diphtheria Antitoxin (DAT)

Definition

A horse-serum-derived antitoxin that neutralizes the diphtheria exotoxin circulating in the bloodstream, given as soon as diphtheria is clinically suspected (before lab confirmation).

Importance

Antitoxin is the MOST IMPORTANT treatment — given immediately to prevent myocarditis and neuritis. Do not wait for culture results.

Term

Bull Neck

Definition

The swollen, thick-appearing neck caused by massive cervical lymphadenopathy and soft tissue edema in diphtheria.

Importance

A classic NLE descriptor for diphtheria — helps distinguish it from other throat infections.

Section Title

Diphtheria

Common Mistakes

  • Attempting to remove the pseudomembrane — this causes BLEEDING and can dislodge pieces that obstruct the airway. NEVER remove it forcibly.
  • Forgetting to prescribe strict BED REST — diphtheria toxin causes myocarditis, and physical exertion can trigger fatal cardiac arrhythmias.
  • Waiting for culture results before giving antitoxin — DAT must be given IMMEDIATELY on clinical suspicion.
  • Using only antibiotics without antitoxin — antibiotics eliminate bacteria but do NOT neutralize the toxin.

Exam Tips

  • Dengue fever = DAY-biting mosquito + CLEAN stagnant water = Aedes aegypti. NOT Anopheles (malaria).
  • Warning signs mnemonic: 'SUPER ABD' — Severe abdominal pain, Unstable (restless/lethargic), Persistent vomiting, Epistaxis/mucosal bleeding, Rapid drop in temperature, Abdominal bleeding, BP narrowing, Diaphoresis (cold clammy).
  • Fluid management in dengue: oral hydration first; escalate to IV if warning signs appear.
  • DOH 4-S: Search → Self-protect → Seek early → Support fogging. Know all 4 for NLE.

Key Points

  • Causative agent: Dengue virus (DENV 1–4, four serotypes). Vector: Aedes aegypti mosquito — a DAY-BITING mosquito that breeds in CLEAN, STAGNANT WATER (pots, tires, flower vases).
  • NOT transmitted person-to-person. Second infection with a DIFFERENT serotype carries higher risk of severe dengue.
  • CLINICAL PHASES: (1) FEBRILE phase (Days 1–3) — high fever, severe headache, retro-orbital pain, myalgia/arthralgia ('breakbone fever'), flushed face, rash; (2) CRITICAL phase (Days 4–6) — fever defervesces, plasma leakage → hemoconcentration, risk of DENGUE SHOCK SYNDROME (DSS); (3) RECOVERY phase (Day 7+) — reabsorption of fluids, diuresis.
  • TOURNIQUET TEST (Rumpel-Leede test): Inflate BP cuff to midpoint between systolic and diastolic for 5 minutes. POSITIVE if ≥20 petechiae per 1 square inch — indicates capillary fragility.
  • WARNING SIGNS (must report/admit IMMEDIATELY): Severe abdominal pain, persistent vomiting, mucosal/gum bleeding, restlessness or sudden lethargy, rapid drop in temperature with cold clammy skin (early shock).
  • Laboratory: THROMBOCYTOPENIA (↓platelets <100,000/mm³), HEMOCONCENTRATION (↑hematocrit ≥20% above baseline).
  • Management: NO specific antiviral. FLUID RESUSCITATION is the priority — oral fluids for mild dengue, IV fluids (Ringer's lactate or normal saline) for severe dengue/DSS. Monitor platelet count and hematocrit q4–6h. Use PARACETAMOL for fever. AVOID ASPIRIN and NSAIDs (increase bleeding risk).
  • DOH '4-S' Prevention Strategy: (1) Search and destroy breeding sites; (2) Self-protection (repellents, long clothing, window screens); (3) Seek early consultation; (4) Support fogging (only during outbreaks, not routine).

Definitions

Term

Tourniquet Test (Rumpel-Leede)

Definition

A clinical test for capillary fragility: inflate the BP cuff to midpoint between systolic and diastolic pressure for 5 minutes; a POSITIVE result is ≥20 petechiae per square inch, suggestive of dengue.

Importance

Commonly tested as both a procedural step and an interpretation question on the NLE.

Term

Dengue Shock Syndrome (DSS)

Definition

The most severe form of dengue, occurring during the critical phase, characterized by massive plasma leakage leading to circulatory failure, hypotension, narrow pulse pressure (<20 mmHg), and signs of shock.

Importance

Recognizing the transition from dengue fever to DSS (warning signs) is a critical nursing safety competency.

Term

Hemoconcentration

Definition

An increase in hematocrit (≥20% above baseline) due to plasma leakage out of blood vessels in dengue hemorrhagic fever, causing the blood to become more concentrated.

Importance

Rising hematocrit signals worsening dengue — a key lab monitoring parameter.

Section Title

Dengue Fever and Dengue Hemorrhagic Fever

Common Mistakes

  • Giving aspirin or ibuprofen (NSAIDs) for dengue fever — these inhibit platelet function and WORSEN BLEEDING. Always use PARACETAMOL.
  • Fogging as a routine prevention measure — DOH 4-S specifies fogging ONLY during outbreaks, not for regular prevention.
  • Missing warning signs during the afebrile 'critical phase' — mistaking defervescence for recovery when it actually signals plasma leakage.
  • Forgetting to monitor BOTH platelets AND hematocrit — platelet count alone is insufficient.

Formulas

Example

A 10 kg child with some dehydration: ORS = 75 mL × 10 kg = 750 mL over 4 hours (approximately 187.5 mL/hour). After 4 hours, reassess the child's hydration status.

Formula

ORS Volume for Plan B = 75 mL × body weight (kg)

Variables

75 mL/kg is the WHO/DOH recommended ORS dose for 'some dehydration'; administered over 4 hours

Application

Calculate the total volume of ORS to give a child with some dehydration at the health facility over 4 hours of supervised rehydration.

Exam Tips

  • IMCI dehydration plans: No dehydration = Plan A (home/ORS + zinc); Some dehydration = Plan B (ORS 75 mL/kg × 4h supervised); Severe dehydration = Plan C (IV fluids immediately).
  • ORS + Zinc = the two non-negotiable components of diarrhoea management at all levels.
  • Zinc duration: 10–14 days regardless of how quickly the diarrhoea resolves.
  • If a question asks about IV fluid choice in severe dehydration → Ringer's Lactate is preferred over Normal Saline.

Key Points

  • Leading cause of under-5 death globally and in the Philippines. The DANGER is DEHYDRATION.
  • Most common cause in children: ROTAVIRUS (viral — vaccine now available); also bacterial (E. coli, Salmonella, Shigella) and parasitic (Entamoeba, Giardia).
  • IMCI/DOH DEHYDRATION ASSESSMENT and TREATMENT PLANS:
  • PLAN A (No Dehydration): Home management — give EXTRA FLUIDS after each loose stool, continue breastfeeding/feeding, give ZINC, return if worsens.
  • PLAN B (Some Dehydration — 2 signs: restless/irritable, sunken eyes, drinks eagerly/thirsty, decreased skin turgor): Supervised ORS administration — 75 mL/kg over 4 HOURS at health facility, then REASSESS.
  • PLAN C (Severe Dehydration — lethargic/unconscious, sunken eyes, unable to drink, very poor skin turgor): IV FLUIDS IMMEDIATELY — Ringer's Lactate (preferred) or Normal Saline. If unable to insert IV, use nasogastric ORS or refer to hospital.
  • ZINC SUPPLEMENTATION: 10 mg/day for infants < 6 months; 20 mg/day for children ≥ 6 months — given for 10–14 DAYS to reduce duration, severity, and recurrence of diarrhoea.
  • CONTINUE BREASTFEEDING and FEEDING throughout diarrhoea — DO NOT withhold food (worsens malnutrition and prolongs illness).
  • ORS formula: Low-osmolarity ORS (DOH/WHO standard) — sodium 75 mEq/L, glucose 75 mmol/L, osmolarity 245 mOsm/L.
  • Nursing diagnosis priorities: Deficient Fluid Volume (priority), Diarrhoea, Risk for Impaired Skin Integrity (perianal), and Deficient Knowledge (caregivers).

Definitions

Term

Oral Rehydration Solution (ORS)

Definition

A glucose-electrolyte solution used to replace fluid and electrolyte losses from diarrhoea. The DOH/WHO standard is low-osmolarity ORS (245 mOsm/L). It works by using the sodium-glucose cotransport mechanism in the intestine.

Importance

ORS is the CORNERSTONE of diarrhoea management. Knowing when and how to use Plans A, B, and C is critical for the NLE.

Term

Zinc Supplementation in Diarrhoea

Definition

Zinc is given as an adjunct to ORS for 10–14 days: 10 mg/day for infants <6 months, 20 mg/day for children ≥6 months. It reduces intestinal permeability and supports immune function, reducing diarrhoea duration and severity.

Importance

A commonly tested NLE fact — know the dose by age group and the duration (10–14 days).

Section Title

Diarrhoeal Disease and ORS/ZINC Management

Common Mistakes

  • Withholding food or breastfeeding during diarrhoea — this is WRONG and worsens nutritional status. CONTINUE feeding.
  • Giving the wrong zinc dose: 10 mg (<6 months) vs. 20 mg (≥6 months) — mixing these up is a common NLE error.
  • Stopping zinc after 2–3 days when the diarrhoea improves — zinc must be given for the FULL 10–14 days.
  • Confusing Plan B volume — it is 75 mL/kg over 4 HOURS (not 100 mL/kg, not 1 hour).

Exam Tips

  • Mnemonic for IMCI danger signs: 'VLC-B' — Vomits everything, Lethargic/unconscious, Convulsions, Cannot drink/Breastfeed.
  • Fast-breathing cutoffs: Under 2 months = 60; 2–12 months = 50; 1–5 years = 40. Think: '60-50-40 going down with age.'
  • IMCI color sequence: Pink = serious/refer; Yellow = treat at facility; Green = home. Think traffic light: Red (stop/refer), Yellow (treat), Green (go home).
  • Chest indrawing in a child ≥2 months = severe pneumonia = Pink = refer. But in a young infant <2 months, ANY chest indrawing = severe disease = refer.
  • IMCI integrates curative AND preventive care: always check immunizations and nutrition at every visit.

Key Points

  • IMCI is a WHO/UNICEF/DOH strategy to reduce under-5 mortality by managing the WHOLE sick child — not one disease at a time — at the PRIMARY CARE (RHU/health center) level.
  • The approach: ASSESS → CLASSIFY → TREAT → COUNSEL → FOLLOW-UP.
  • TWO AGE-BASED CHARTS: (1) YOUNG INFANT: 1 week to 2 months; (2) CHILD: 2 months to 5 years.
  • COLOUR-CODED CLASSIFICATION SYSTEM: PINK = Urgent referral/hospitalise (severe disease); YELLOW = Treat at facility + home care; GREEN = Home management with advice.
  • GENERAL DANGER SIGNS (any sign = URGENT REFERRAL, PINK classification): (1) NOT ABLE TO DRINK OR BREASTFEED; (2) VOMITS EVERYTHING; (3) CONVULSIONS during current illness; (4) LETHARGIC OR UNCONSCIOUS.
  • MAIN SYMPTOMS ASSESSED IN CHILDREN 2 MONTHS – 5 YEARS: (1) Cough or difficult breathing; (2) Diarrhoea; (3) Fever; (4) Ear problem; PLUS check nutrition/anaemia, immunisation, feeding, and counsel the caregiver.
  • FAST BREATHING THRESHOLDS (pneumonia cutoffs): <2 months = ≥60 breaths/min; 2–12 months = ≥50 breaths/min; 12 months–5 years = ≥40 breaths/min.
  • CHEST INDRAWING (lower chest wall draws IN with inspiration) = SEVERE PNEUMONIA → urgent referral (PINK). Non-severe fast breathing without indrawing → oral amoxicillin + home care.
  • YOUNG INFANT DANGER SIGNS (trigger urgent referral): Not feeding well, convulsions, fast breathing ≥60/min, severe chest indrawing, fever ≥37.5°C OR low temperature <35.5°C, movement only when stimulated or no movement at all.
  • The IMCI chart also assesses: breastfeeding/attachment (young infant), jaundice, malnutrition (MUAC, oedema), and immunisation status — integrating preventive care with curative care.
  • The RHU nurse in the Philippines is the front-line IMCI implementer — this aligns with the community health nursing role under RA 9173.

IMCI (Integrated Management of Childhood Illness)

Definition

A WHO/UNICEF/DOH clinical strategy for assessing, classifying, treating, and counseling caregivers of sick children under 5 years at the primary care level, using standardized color-coded classification tools to ensure holistic, integrated management.

Importance

The framework that organizes ALL of pediatric primary care in the Philippines — essential for NLE and RHU nursing practice.

Term

General Danger Signs (IMCI)

Definition

Four critical signs in any sick child that indicate severe illness requiring IMMEDIATE URGENT REFERRAL: (1) unable to drink/breastfeed, (2) vomits everything, (3) convulsions, (4) lethargic or unconscious.

Importance

MUST be assessed in EVERY sick child before any other evaluation. Any one of these = Pink = Refer NOW.

Term

Chest Indrawing

Definition

A sign of severe respiratory distress in which the lower chest wall visibly draws INWARD during inspiration, indicating the child is using increased effort to breathe. It is a sign of severe pneumonia in IMCI classification.

Importance

Chest indrawing = severe pneumonia = Pink classification = urgent referral. Frequently tested NLE scenario.

Section Title

Integrated Management of Childhood Illness (IMCI)

Common Mistakes

  • Counting respiratory rate for less than a full MINUTE — must count for a full 60 seconds for accuracy.
  • Applying the wrong fast-breathing threshold for the child's age group — memorize all three cutoffs.
  • Forgetting to check GENERAL DANGER SIGNS first in every sick child visit.
  • Confusing chest indrawing with intercostal retractions — IMCI specifically refers to LOWER chest wall indrawing.
  • Failing to counsel the caregiver on when to RETURN IMMEDIATELY — a required component of every IMCI visit.

Exam Tips

  • Vitamin A memory aid: '6–11 months = 100,000 IU (1 dose once); 12–59 months = 200,000 IU (every 6 months).' The dose DOUBLES after 12 months.
  • GP = April + October (twice a year) = Vitamin A + Deworming + Immunization catch-up.
  • EPI schedule: Birth (BCG + Hep B); 6–10–14 weeks (Pentavalent + OPV + PCV ± Rotavirus); 9 months (MCV1/Measles); 12–15 months (MMR).
  • NLE often presents scenarios about which vaccines are due — calculate age and match to the EPI schedule.

Key Points

  • EXPANDED PROGRAM ON IMMUNIZATION (EPI): The DOH's national program to prevent vaccine-preventable childhood diseases, providing free vaccines through RHUs and health centers.
  • EPI SCHEDULE KEY VACCINES: BCG + Hepatitis B (at BIRTH); Pentavalent (DPT-HepB-Hib) + OPV + PCV at 6 weeks, 10 weeks, and 14 weeks; Measles-containing vaccine (MCV1) at 9 months; MMR (MCV2) at 12–15 months; Rotavirus vaccine (2 doses) at 6 and 10 weeks.
  • GARANTISADONG PAMBATA (GP): A DOH program delivering a package of health services to children TWICE a year (biannual) — typically in April and October.
  • GP PACKAGE includes: (1) Vitamin A supplementation; (2) Deworming (mebendazole/albendazole); (3) Immunisation catch-up; (4) Weight monitoring; (5) Health education for caregivers.
  • VITAMIN A DOSES under Garantisadong Pambata: 100,000 IU ONCE for infants 6–11 months; 200,000 IU every 6 months for children 12–59 months (1 year to 4 years 11 months).
  • Vitamin A is ALSO given therapeutically in MEASLES cases (regardless of age) to reduce complications.
  • These programs align with NCM 103 (Community Health Nursing) competencies and are frequently referenced in NLE scenario questions.

Definitions

Term

Expanded Program on Immunization (EPI)

Definition

The DOH national immunization program that provides free, universal vaccines to children to prevent tuberculosis, polio, diphtheria, tetanus, pertussis, hepatitis B, Hib, measles, rubella, mumps, pneumococcal disease, and rotavirus diarrhoea.

Importance

The EPI schedule is tested in NLE — know which vaccine is given at birth, 6–10–14 weeks, and 9–12 months.

Term

Garantisadong Pambata (GP)

Definition

A DOH biannual (twice-yearly) child-health campaign providing Vitamin A supplementation, deworming, immunization catch-up, growth monitoring, and health education for children under 5 years.

Importance

GP Vitamin A doses by age group are frequently tested on the NLE — memorize the doses: 100,000 IU (6–11 months) and 200,000 IU (12–59 months).

Section Title

DOH Programs Supporting Child Health: EPI and Garantisadong Pambata

Common Mistakes

  • Giving 200,000 IU of Vitamin A to a 9-month-old infant — the dose for 6–11 months is 100,000 IU (NOT 200,000 IU).
  • Saying Garantisadong Pambata is annual — it is BIANNUAL (twice a year, typically April and October).
  • Forgetting that measles cases ALSO receive therapeutic Vitamin A, separate from the GP schedule.

Connections

  • IMCI integrates the assessment and management of all communicable diseases (measles, diarrhoea, dengue, pneumonia) into ONE systematic framework — understanding IMCI helps you remember and organize ALL the individual disease management principles.
  • The EPI schedule prevents MOST of the communicable diseases covered in this chapter: measles (MMR), pertussis (Pentavalent), diphtheria (Pentavalent), rubella (MMR), mumps (MMR) — failure to immunize is the root cause of most childhood disease outbreaks.
  • Vitamin A connects measles management and Garantisadong Pambata — it is given therapeutically for measles AND preventively through GP, reinforcing the link between curative and preventive nursing care.
  • Dengue management (fluid resuscitation, monitoring hematocrit/platelets) connects to the broader nursing competency of hemodynamic monitoring and shock management, which also applies to diarrhoea with severe dehydration (Plan C).
  • The NANDA nursing diagnosis 'Hyperthermia' applies across all communicable diseases — management (paracetamol, tepid sponge, adequate fluids) is the same, while the CAUSE and specific medications to AVOID (aspirin in varicella, NSAIDs in dengue) differ by disease.
  • Maslow's hierarchy guides priority nursing actions: PHYSIOLOGIC needs first (airway in diphtheria/pertussis, fluid in dengue/diarrhoea, fever management) → SAFETY (isolation, preventing transmission) → LOVE/BELONGING (caregiver counseling and support) → SELF-ACTUALIZATION (health education, disease prevention).
  • RA 9173 (Philippine Nursing Act) authorizes the RN to independently implement IMCI, administer EPI vaccines, initiate isolation precautions, and refer to higher-level care — all competencies directly applicable to the community health nursing role at the RHU level.
  • Diarrhoea ORS Plan B (75 mL/kg over 4 hours) connects to the nursing skill of fluid calculations — the same mathematical approach used in IV therapy calculations, reinforcing the need for accurate weight-based dosing.

Exam Strategy

For the NLE on Communicable Diseases in Children and IMCI, use the following strategy: STEP 1 — For each disease question, immediately identify the KEY TRIAD: (a) mode of transmission → isolation precaution, (b) hallmark/pathognomonic sign, and (c) most dangerous complication. STEP 2 — For IMCI questions, apply the ASSESS → CLASSIFY → ACT sequence: identify the general danger signs FIRST (any danger sign = Pink = refer now), then classify by severity using the color-coded system. STEP 3 — For diarrhoea management, identify the dehydration level from clinical signs and apply the correct Plan (A/B/C) with accurate ORS volumes and zinc doses. STEP 4 — For medication safety questions, remember the two critical drug contraindications: NO ASPIRIN in varicella (Reye's syndrome) and NO ASPIRIN/NSAIDs in dengue (bleeding risk). STEP 5 — For Garantisadong Pambata and EPI questions, recall the two Vitamin A doses: 100,000 IU (6–11 months) and 200,000 IU (12–59 months). Always choose the option that prioritizes PHYSIOLOGIC SAFETY first (airway, circulation, hydration), consistent with Maslow-based prioritization. Eliminate options that give aspirin to children, remove the diphtheria pseudomembrane, or withhold food during diarrhoea — these are classic NLE wrong-answer distractors.

Quick Review Questions

A 3-year-old child is brought to the RHU with high fever, runny nose, cough, conjunctivitis, and photophobia. On examination, the nurse notices tiny bluish-white spots on the inner cheek before the rash appears. What are these spots called, and what disease do they confirm?

Koplik spots appear on the buccal mucosa 1–2 days BEFORE the measles rash emerges. They are the definitive clinical sign of measles. The nurse should initiate AIRBORNE precautions immediately and prepare Vitamin A supplementation as part of management.

The nurse is caring for a 2-year-old child with varicella. The mother asks if she can give aspirin for the child's fever. What is the nurse's best response and rationale?

Reye's syndrome is a critical safety concern in children with varicella or influenza. Paracetamol is the safe alternative for fever management. This is a high-priority patient safety nursing action that is commonly tested on the NLE.

Using IMCI, a nurse assesses a 10-month-old child with cough and counts the respiratory rate as 52 breaths per minute with visible chest indrawing. How should the nurse classify this child and what is the appropriate action?

In IMCI, chest indrawing in a child 2 months to 5 years = severe pneumonia = Pink (urgent referral). Fast breathing alone (without indrawing) would be non-severe pneumonia (Yellow = oral amoxicillin at home). The nurse must never delay referral for a Pink child.

A 7-month-old infant presents at the health center with diarrhoea for 2 days. Assessment reveals: restless and irritable, sunken eyes, drinks water eagerly/with thirst, skin pinch goes back slowly. What IMCI dehydration plan should the nurse implement, and how much ORS should be given?

Plan B is for 'some dehydration' — defined by 2 or more signs: restless/irritable, sunken eyes, thirsty/drinks eagerly, slow skin turgor. The nurse administers ORS under direct supervision (not sent home), then reassesses dehydration status after 4 hours to determine if Plan A, B, or C is needed next.

A child with suspected diphtheria is admitted. The nurse observes a thick grey membrane over the tonsils. What is the FIRST priority nursing and medical intervention?

In diphtheria, the exotoxin causes the most life-threatening complications (myocarditis, neuritis). Antitoxin neutralizes only UNBOUND toxin in the bloodstream — delay worsens cardiac and neurological outcomes. Antibiotics (penicillin/erythromycin) are given concurrently to eliminate the bacteria but do not neutralize toxin. The nurse must NEVER attempt to remove the pseudomembrane.

A 6-year-old child with dengue fever becomes suddenly afebrile on Day 4, appears restless, has cold clammy hands, and the mother reports blood in the gums. What phase of dengue is this, and what is the nurse's priority action?

The 'apparent recovery' when fever drops is DECEPTIVE — it actually signals the start of the critical phase. Warning signs present here include: restlessness, cold clammy extremities, and mucosal bleeding. These mandate immediate intervention. Paracetamol only for fever; absolutely NO aspirin/NSAIDs which worsen bleeding.

During Garantisadong Pambata, the nurse is administering Vitamin A supplementation. What dose should be given to a 14-month-old child?

Under Garantisadong Pambata: 6–11 months = 100,000 IU (given ONCE); 12–59 months = 200,000 IU (given every 6 months, i.e., biannually). A 14-month-old falls in the 12–59 months group. Therapeutic Vitamin A is also given in all measles cases using age-appropriate doses.

A 4-year-old child presents with paroxysmal coughing followed by a high-pitched sound when breathing in, and vomiting after each coughing episode. The child's lips turn bluish during the attack. What is the most likely diagnosis, what is the drug of choice, and what specific danger must the nurse monitor for in a younger infant with the same disease?

Pertussis is caused by Bordetella pertussis, transmitted by droplet. The classic paroxysmal cough + inspiratory whoop + post-tussive vomiting + cyanosis occurs in older children. In infants, apnea is the most dangerous manifestation and requires hospitalization, apnea monitoring, and oxygen. Penicillin is NOT the drug of choice — macrolides are.
