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

Communicable diseases in Filipino children remain a public health challenge, despite the Expanded Program on Immunization (EPI) coverage. The most common preventable childhood exanthems—measles, mumps, varicella, pertussis, diphtheria, and rubella—are vaccine-preventable through the DOH EPI schedule. Non-vaccine-preventable diseases, particularly dengue fever and diarrhoeal illnesses (often viral, caused by rotavirus), account for significant hospitalisations and deaths. Understanding the epidemiology helps nurses identify risk factors: crowded living conditions, poor sanitation, incomplete immunisation, and malnutrition are common in rural and urban poor communities in the Philippines. The nursing role encompasses PRIMARY PREVENTION (health education, immunisation campaigns, environmental sanitation advocacy), SECONDARY PREVENTION (early identification of disease, prompt isolation, contact tracing), and TERTIARY PREVENTION (managing complications, preventing sequelae). According to RA 9173 (The Philippine Nursing Act of 2002), nurses are mandated to engage in health promotion and disease prevention at all levels of healthcare—from the barangay health station (BHS) to the regional medical center (RMC). The IMCI strategy operationalizes this mandate by placing the frontline RHU nurse as the first-line assessor and classifier of the sick child.

Measles remains a leading vaccine-preventable cause of child mortality globally and in the Philippines. The measles virus is highly contagious and spreads via AIRBORNE DROPLET NUCLEI—a single infected child can infect 12–18 susceptible contacts. The incubation period is 10–14 days (range: 7–21 days). CLINICAL PRESENTATION follows a predictable pattern: The PRODROMAL PHASE (2–4 days) includes the "3 C's"—high fever (often 39–40°C), COUGH, CORYZA (rhinorrhea/runny nose), and CONJUNCTIVITIS—accompanied by photophobia (light sensitivity) and malaise. During this phase, the nurse observes the child's preference for dim lighting and cries when the lights are turned up. The PATHOGNOMONIC HALLMARK SIGN is KOPLIK SPOTS: tiny (1–3 mm), bluish-white spots with red halos appearing on the BUCCAL MUCOSA (inside the cheeks, opposite the molars). Koplik spots appear 2–3 days before the rash and fade as the rash emerges. They are highly specific for measles and crucial for early diagnosis before widespread rash transmission occurs. The RASH PHASE begins as the fever often spikes higher. The maculopapular rash appears first on the face, hairline, and behind the ears, then spreads CEPHALOCAUDALLY (head to toe) over 3 days, reaching the feet by day 3. The rash is confluent on the face/trunk and blanches on pressure. As it fades, the rash turns brownish and desquamation may occur. The rash fades in the SAME ORDER it appeared (cephalocaudal). COMMON COMPLICATIONS include: (1) PNEUMONIA—the leading cause of measles-related death in children, presenting with tachypnea, chest indrawing, and hypoxia; (2) OTITIS MEDIA—secondary bacterial infection of the middle ear; (3) ENCEPHALITIS—a severe neurologic complication with high fever, altered consciousness, and seizures; (4) Secondary bacterial infections (impetigo, abscess) from scratching. Malnourished or immunocompromised children are at highest risk. NURSING MANAGEMENT emphasizes AIRBORNE PRECAUTIONS: isolate the child in a single room or cohort with negative-pressure ventilation (if available), use N95 respirators for healthcare workers, and restrict non-immune visitors. Symptomatic management includes: rest, adequate hydration (broths, oral rehydration solutions), antipyretics (paracetamol, NOT aspirin), and maintenance of dim lighting to reduce photophobia. VITAMIN A SUPPLEMENTATION is mandatory for all children with measles: the WHO/DOH recommends 200,000 IU for children ≥1 year; 100,000 IU for 6–11 months; 50,000 IU for <6 months—given on day 1, day 2, and 2 weeks later. Vitamin A reduces severity, duration, and mortality by 12–24%. Monitor for complications: if pneumonia develops (tachypnea ≥40/min for age, chest indrawing), refer for oxygen and antibiotics (amoxicillin or ceftriaxone). If encephalitis is suspected (severe altered consciousness, seizures), refer for supportive care and possible ICU monitoring.

Mumps is a vaccine-preventable viral infection spread by DROPLET TRANSMISSION. The mumps virus infects the salivary glands, particularly the parotid glands, though it is a systemic illness affecting multiple organs. Incubation is 16–18 days (range: 12–25 days). CLINICAL PRESENTATION: The hallmark and defining sign is BILATERAL PAROTID SWELLING (or sometimes unilateral), which is firm, tender, and palpable in front of and below the ears. The onset is often sudden, with HIGH FEVER (38–40°C), MALAISE, ANOREXIA (loss of appetite), and PAIN ON CHEWING or SWALLOWING. The pain is often severe and worsens when the child eats sour or acidic foods (citrus, vinegar). The child may refuse meals or complain of ear pain. The swelling peaks around day 3–5 and resolves over 7–10 days. COMPLICATIONS vary by age and sex: (1) MENINGITIS (viral meningitis is the most common CNS complication, presenting with headache, neck stiffness, and fever); (2) ENCEPHALITIS (less common, with altered consciousness and seizures); (3) ORCHITIS (testicular inflammation in post-pubertal males, occurring 1–2 weeks after parotitis onset; presents with severe testicular pain, swelling, and fever; risk of sterility/subfertility if bilateral); (4) OOPHORITIS (ovarian inflammation in adolescent females, causing lower abdominal pain); (5) MYOSITIS, MASTITIS, PANCREATITIS, and DEAFNESS (rare but serious). Deafness may be permanent and unilateral or bilateral. NURSING MANAGEMENT requires DROPLET PRECAUTIONS: isolate for 5 days from symptom onset (or until swelling resolves), use surgical masks for healthcare workers and visitors, and maintain respiratory hygiene. Pain and fever management are central: administer ANALGESICS (paracetamol or ibuprofen, but note: NSAIDs may worsen pancreatitis if it develops) and ANTIPYRETICS. Apply warm or cool COMPRESSES to the parotids (as tolerated by the child) to ease pain. Encourage a SOFT, BLAND DIET—avoid hard, sour, or spicy foods. Broth, mashed potatoes, yogurt, and milk are well-tolerated. Hydration is important; offer water and bland drinks. STRICT AVOIDANCE OF SOUR FOODS is critical—citrus, vinegar-based foods, and acidic drinks provoke pain and further salivary secretion. For suspected MENINGITIS (headache, stiff neck, photophobia), refer urgently. For ORCHITIS in adolescent males, pain management and warm scrotal support (suspensory) are important; high-dose analgesia may be needed. Counsel adolescent males that orchitis carries a risk of reduced fertility if bilateral. Monitor for signs of encephalitis (altered consciousness, seizures). Ensure the child is kept WARM and has COMPLETE BED REST during the acute phase. Vaccination with MMR (measles, mumps, rubella) is the best prevention—two doses provide >99% immunity. Post-exposure prophylaxis with MMR vaccine within 72 hours may offer some protection if given before incubation period is complete.

Varicella (chickenpox) is a highly contagious, vaccine-preventable illness caused by the varicella-zoster virus (VZV). Transmission occurs via AIRBORNE DROPLETS and DIRECT CONTACT with vesicular fluid—it spreads easily in crowded settings like schools and day-care centers. The virus can remain viable in the air for up to 2 hours. Incubation is 10–21 days (typically 14–16 days). CLINICAL PRESENTATION: Prodromal symptoms (low-grade fever, malaise, mild cough) may appear 1–2 days before the rash. The HALLMARK is the CHARACTERISTIC VESICULAR RASH appearing in "CROPS" or successive waves over 3–7 days. A key feature is that lesions are present in ALL STAGES SIMULTANEOUSLY: MACULES (flat red spots), PAPULES (raised bumps), VESICLES (fluid-filled blisters), and CRUSTS (dried scabs) are visible on the same child at the same time. Individual vesicles are classically described as "DEWDROPS ON A ROSE PETAL." The rash is intensely PRURITIC (itchy) and typically involves the trunk and face first, then spreads to limbs; palms and soles are usually spared. The CONTAGIOUS PERIOD is crucial: from approximately 1–2 days BEFORE the rash appears until ALL lesions have CRUSTED OVER (typically 7–10 days). Unlike measles and rubella, varicella contagion is prolonged because scabbing takes days; therefore, isolation is necessary to prevent spread. COMPLICATIONS include: (1) SECONDARY BACTERIAL INFECTION (from scratching)—the most common complication, presenting as impetigo or abscess; (2) ENCEPHALITIS (CNS involvement with fever, altered consciousness, ataxia); (3) VARICELLA PNEUMONITIS (especially in immunocompromised children or infants); (4) CONGENITAL VARICELLA SYNDROME (if infection occurs in the first or early second trimester of pregnancy—cataracts, limb atrophy, CNS damage); (5) REYE SYNDROME (a rare but severe encephalopathy and hepatitis associated with aspirin use during varicella or influenza). Immunocompromised children face disseminated disease risk. NURSING MANAGEMENT emphasizes INFECTION CONTROL with AIRBORNE + CONTACT PRECAUTIONS: isolation in a single room (or cohort with other varicella cases), N95 respirators for healthcare workers entering the room, restricted non-immune visitors, and careful handling of soiled linens/dressings. Symptomatic management is symptomatic: (1) ANTIHISTAMINES (chlorpheniramine, cetirizine) to reduce pruritus; (2) TEPID BATHS or COOL OATMEAL SOAKS (NOT hot water, which worsens itching); (3) CALAMINE LOTION application to lesions (cooling, soothing); (4) ANTIPYRETICS (paracetamol for fever)—but NEVER ASPIRIN or NSAIDs (Reye syndrome risk, salicylate teratogenicity); (5) KEEP NAILS SHORT and encourage non-scratching to prevent secondary infection; consider soft mittens for young children. For HIGH-RISK CHILDREN (immunocompromised, neonates born to varicella-infected mothers within 5 days of birth, premature infants <28 weeks), ACYCLOVIR is indicated (10–20 mg/kg IV or oral, depending on severity and age). For immunocompetent children, antiviral therapy is not routine but may be considered if started within 24 hours of rash onset in select cases. VACCINATION (varicella vaccine, 2 doses) is the best prevention. In the Philippines, the varicella vaccine is not yet part of the EPI but may be available in private and select public facilities. Post-exposure prophylaxis (vaccine within 3–5 days or acyclovir) may modify or prevent disease. EDUCATION is critical: Emphasize to caregivers that scratching prolongs healing, introduces bacteria, and leaves scars. Counsel on keeping the child's environment clean, washing hands frequently, and monitoring for signs of secondary infection (warmth, pus, spreading redness).

Pertussis is a vaccine-preventable respiratory infection caused by *Bordetella pertussis*, spread via DROPLET TRANSMISSION. It is mandatory reportable in the Philippines. The disease is particularly dangerous in young infants (<6 months), who face the highest risk of severe complications and death. Incubation is 7–21 days (typically 10 days). Infectivity is highest during the catarrhal and early paroxysmal stages. CLINICAL PROGRESSION occurs in THREE DISTINCT STAGES: (1) CATARRHAL STAGE (1–2 weeks): Indistinguishable from a common cold—mild rhinorrhea, low-grade fever, mild cough, sneezing. The child appears minimally ill. Parents often do not suspect pertussis at this point, delaying diagnosis. The nurse should maintain high clinical suspicion in unvaccinated or incompletely vaccinated children. (2) PAROXYSMAL STAGE (2–8 weeks, sometimes longer): The hallmark and defining feature is PAROXYSMS OF SEVERE COUGHING. A paroxysm is a sudden, explosive burst of rapid, repetitive coughs without inhalation—the child may cough 5–20 times in a single breath. After the paroxysm, the child attempts to inhale, producing the characteristic HIGH-PITCHED INSPIRATORY "WHOOP" sound (from laryngeal narrowing). The paroxysm may be followed by POST-TUSSIVE VOMITING (vomiting after coughing), mucus expectoration, and cyanosis (bluish discoloration from temporary hypoxia). Between paroxysms, the child appears relatively well, which is unusual for such severe coughing. Paroxysms may occur many times per day, especially at night, disrupting sleep. In infants, the whoop may be absent; instead, they present with apnea (cessation of breathing) or gasping, which is life-threatening. (3) CONVALESCENT STAGE (weeks to months): Gradual decrease in paroxysm frequency and severity over weeks; cough may persist for months ("100-day cough"). COMPLICATIONS are especially serious in infants: (1) APNEA (most dangerous in <6 months; infant stops breathing during or after paroxysm); (2) SECONDARY BACTERIAL PNEUMONIA (superinfection, complicating recovery); (3) OTITIS MEDIA; (4) SEIZURES (from hypoxia or rarely from toxin); (5) ENCEPHALOPATHY (brain inflammation); (6) MALNUTRITION (repeated vomiting and poor intake); (7) RIB FRACTURES (from vigorous coughing, especially in infants); (8) RECTAL PROLAPSE (straining from coughing). NURSING MANAGEMENT requires DROPLET PRECAUTIONS: isolate for at least 5 days from the START OF ANTIBIOTICS (or 3 weeks from cough onset if no antibiotic is given). Healthcare workers and close contacts wear surgical masks. Symptomatic care emphasizes gentle handling and close monitoring: — ANTIBIOTIC THERAPY: MACROLIDE antibiotics (erythromycin, azithromycin, or clarithromycin) are the first-line treatment, effective if started early (catarrhal or early paroxysmal stage). Dosing varies: azithromycin is commonly used (10 mg/kg on day 1, then 5 mg/kg daily for 4 days). These antibiotics reduce the duration and severity of disease and allow earlier return to normal activities. Close contacts (family members, caregivers, classmates) should also receive prophylactic macrolides to prevent secondary cases. — GENTLE SUCTIONING: Use soft suction to remove secretions, avoiding aggressive suctioning which may trigger apnea. — OXYGEN: For infants or children with cyanosis or apnea spells, supplemental oxygen should be available. Consider continuous pulse oximetry monitoring in infants. — POSITIONING: Keep the child upright or semi-recumbent to ease breathing; avoid supine position (increases apnea risk). — HYDRATION: Offer small, frequent feeds (breast milk, formula, or water). Post-tussive vomiting may require refeeding after 20–30 minutes. Monitor for signs of dehydration. — NUTRITIONAL SUPPORT: Multiple small meals are better tolerated than large ones. NG feeding may be needed in severe cases or infants unable to feed safely. — MONITORING FOR APNEA: In infants, continuous observation or pulse oximetry/apnea monitor is critical. Teach caregivers to recognize apnea signs (cessation of breathing, color change, altered consciousness) and initiate basic life support if needed. — EMOTIONAL SUPPORT: The relentless cough is distressing; provide reassurance and calm environment. Hospitalization is indicated for infants <6 months, children with apnea, severe cyanosis, pneumonia, or poor nutritional intake. Secondary bacterial pneumonia requires additional antibiotics (amoxicillin, ceftriaxone). VACCINATION (DPT/pentavalent at 6, 10, 14 weeks; booster at 18 months) is the cornerstone of prevention. Close contacts without up-to-date vaccination should receive prophylactic antibiotics (same macrolide regimen) and catch-up vaccination.

Diphtheria is a vaccine-preventable, potentially life-threatening respiratory infection caused by *Corynebacterium diphtheriae*, which produces a potent exotoxin. Transmission occurs via DROPLET INHALATION. Although EPI coverage has reduced incidence in the Philippines, sporadic cases and outbreaks occur in areas with low immunisation coverage or in immunized individuals waning immunity. Incubation is 2–7 days (typically 3–4 days). CLINICAL PRESENTATION is often insidious. Early signs mimic a sore throat: low-grade fever (often <39°C), sore throat, and malaise. The HALLMARK and PATHOGNOMONIC SIGN is a THICK, GREYISH-WHITE PSEUDOMEMBRANE over the tonsils, pharynx, larynx, or (in cutaneous diphtheria) over skin wounds. The pseudomembrane is adherent and bleeds if forcibly removed, distinguishing it from the friable membrane of strep throat. The membrane can spread, potentially obstructing the airway. A characteristic finding is "BULL NECK"—cervical edema and swelling from enlarged lymph nodes and soft-tissue inflammation, giving a bull-like appearance. This swelling increases airway obstruction risk. COMPLICATIONS are severe: (1) AIRWAY OBSTRUCTION (from membrane extension or edema, requiring emergency airway management); (2) MYOCARDITIS (the most dreaded complication)—the diphtheria toxin damages the myocardium, causing cardiac arrhythmias, heart failure, shock, and sudden cardiac death; typically occurs 1–3 weeks after symptom onset; (3) NEURITIS (peripheral nerve inflammation, especially the phrenic nerve leading to respiratory paralysis, or cranial nerves causing weakness); (4) TOXIC COMPLICATIONS (seizures, delirium). Myocarditis can be fatal even with treatment. NURSING MANAGEMENT requires HIGH CLINICAL SUSPICION and IMMEDIATE ACTION: — DROPLET PRECAUTIONS: Isolate for 2–7 days (typically 5 days) from the start of antibiotics, or until two consecutive nasopharyngeal swabs (taken 24 hours apart) are negative for *C. diphtheriae*. Use surgical masks. — DIPHTHERIA ANTITOXIN (DAT): This is the CORNERSTONE of treatment and should be given IMMEDIATELY upon clinical suspicion, WITHOUT WAITING for culture confirmation (cultures take days). Delay in antitoxin administration worsens prognosis. Antitoxin neutralizes circulating toxin but cannot reverse tissue damage already done. Dosing depends on the site and severity: 5,000–10,000 IU for pharyngeal diphtheria; up to 100,000 IU for severe or laryngeal disease. Antitoxin is usually given IV or IM (depending on formulation). Before administration, a sensitivity test (intradermal injection of a small amount) must be performed to check for hypersensitivity reactions (anaphylaxis), as antitoxin is derived from horse serum. Epinephrine and resuscitation equipment must be immediately available. — ANTIBIOTICS: Penicillin G (IV preferred for severe disease) or erythromycin (IV or oral). Penicillin dosing: 1.2 million IU IV Q4H for 10–14 days. Erythromycin: 500 mg IV Q6H or oral. Antibiotics eliminate the organism and prevent relapse but do NOT replace antitoxin. — AIRWAY MANAGEMENT: Assess airway patency closely. If stridor (high-pitched breathing sound) or respiratory distress develops, be prepared for emergency intubation or tracheostomy. Keep emergency airway equipment (endotracheal tubes, laryngoscope, tracheostomy tray) immediately available. — STRICT BED REST: Essential because activity increases myocarditis risk. The child should remain flat or in a semi-recumbent position to minimize cardiac workload. — CARDIAC MONITORING: Continuous ECG monitoring for arrhythmias and signs of myocarditis. Monitor for palpitations, chest pain, dyspnea, or syncope. Any sign of cardiac compromise warrants urgent intervention (inotropic support, antiarrhythmics, ICU-level care). — AVOID MEMBRANE REMOVAL: DO NOT attempt to remove or strip the membrane—this risks severe bleeding and dislodgment of the membrane into the airway, causing obstruction and acute death. — NUTRITION AND HYDRATION: Provide liquid diet initially (soft foods may cause membrane irritation and bleeding). If swallowing is compromised, consider IV or NG feeding. — MANAGEMENT OF BULL NECK: Warm compresses may provide comfort. Elevate the head of the bed to reduce neck edema. Hospitalization in a secondary or tertiary facility is MANDATORY. Diphtheria requires ICU-level monitoring for myocarditis and airway complications. Mortality rates range from 5–15% despite treatment, with death typically from myocarditis or airway obstruction. VACCINATION (DPT/pentavalent at 6, 10, 14 weeks; boosters) is the cornerstone of prevention. Post-exposure prophylaxis with antibiotics (erythromycin or azithromycin) and catch-up vaccination is recommended for close contacts.

Dengue is a mosquito-borne viral infection endemic in the Philippines, caused by one of four dengue virus serotypes (DENV 1–4). The vector is the *Aedes aegypti* mosquito—an urban, day-biting mosquito that breeds in clean, stagnant water (stored in containers, flowerpots, discarded bottles, tires, and other receptacles). This is the ONLY vector of dengue in human populations. Aedes egypti typically bites during dawn and dusk but may bite anytime in heavily shaded areas. Transmission does NOT occur via person-to-person contact but only via mosquito bite. CLINICAL PRESENTATION typically progresses through THREE phases: (1) FEBRILE PHASE (3–7 days): Abrupt onset of HIGH FEVER (40–40.5°C or higher), with SEVERE HEADACHE, RETRO-ORBITAL PAIN (pain behind the eyes, made worse by eye movement), MYALGIA (muscle/body aches), and ARTHRALGIA (joint pain)—the syndrome is sometimes called "BREAKBONE FEVER" because the pain is so severe. A generalized MACULOPAPULAR or PETECHIAL RASH often appears. The POSITIVE TOURNIQUET TEST (also called Rumpel-Leede test) is a key sign: a blood pressure cuff is inflated on the arm to a pressure midway between systolic and diastolic for 5 minutes; afterwards, if >20 petechiae (tiny red/purple spots from capillary fragility) appear in a 1 cm² area on the forearm, the test is positive, indicating increased capillary fragility (early bleeding tendency). During this phase, the platelet count begins to drop. (2) CRITICAL PHASE ("PLASMA LEAKAGE PHASE," around days 3–7, typically days 3–5): This is the most dangerous period. As fever falls, the child may appear to "recover," but this is DECEPTIVE. Increased capillary permeability leads to PLASMA LEAKAGE: fluid shifts from the intravascular space to the interstitial space, causing: (a) HEMOCONCENTRATION (increase in hematocrit and hemoglobin), (b) THROMBOCYTOPENIA (severe drop in platelets), (c) BLEEDING MANIFESTATIONS (petechiae, gum bleeding, epistaxis—nosebleed, hemoptysis—coughing blood, melena—black tarry stools, hematuria—blood in urine), and (d) DENGUE SHOCK SYNDROME (DSS)—a potentially fatal state of circulatory failure from severe fluid loss, presenting with tachycardia, narrowed pulse pressure, hypotension, cold clammy extremities, and altered consciousness. WARNING SIGNS are RED FLAGS that should prompt IMMEDIATE referral and intensification of monitoring and fluid management. The DOH/WHO lists key warning signs: — **SEVERE ABDOMINAL PAIN** (right upper quadrant pain is common) — **PERSISTENT VOMITING** (three or more times in 1 hour) — **MUCOSAL/GUM BLEEDING or other bleeding** — **RESTLESSNESS or LETHARGY/altered consciousness** — **RAPID FALL in PLATELET COUNT** (especially if falling faster than hematocrit rising) — **RAPID RISE in HEMATOCRIT** (especially >20% increase from baseline) — **HEPATOMEGALY** (enlarged liver) (3) RECOVERY PHASE (days 7–10 onwards): If the child survives the critical phase, gradual resolution occurs. Platelets recover, plasma leakage stops, and appetite returns. A secondary rash (desquamating rash with islands of sparing) may appear on days 5–7. SEVERE DENGUE (dengue hemorrhagic fever or dengue shock syndrome) is defined by: (1) sustained fever AND (2) bleeding manifestations (petechiae, gum bleeding, hemoptysis, melena, hematuria) + evidence of plasma leakage (hemoconcentration, pleural effusion, ascites, or thrombocytopenia <100,000/μL). DSS adds circulatory failure (tachycardia, narrow pulse pressure, hypotension, cold extremities, altered consciousness). NURSING MANAGEMENT is PRIMARILY SUPPORTIVE, with emphasis on FLUID RESUSCITATION and MONITORING: — NO SPECIFIC ANTIVIRAL: There is no antiviral drug for dengue. Management is supportive. — FLUID MANAGEMENT (THE CORNERSTONE): The goal is to maintain adequate perfusion and prevent hypovolemic shock without over-hydrating and worsening plasma leakage. IV fluid is indicated if the child cannot maintain oral intake due to vomiting or if there are signs of plasma leakage/early shock. IV fluids are typically ISOTONIC CRYSTALLOID (normal saline or Ringer's lactate). Fluid boluses (10–20 mL/kg over 15–30 minutes) are given for signs of shock; then maintenance fluids are calculated based on the child's weight. Careful reassessment is needed every 1–2 hours; fluid rate is adjusted based on vital signs, urine output, hematocrit, and platelet trends. OVER-HYDRATION is dangerous (worsens pulmonary edema, pleural effusion, and plasma leakage); therefore, fluid intake and output must be meticulously recorded. — PLATELET AND HEMATOCRIT MONITORING: Serial platelet counts and hematocrit measurements are critical (every 6–12 hours during the critical phase). A rapidly rising hematocrit (>20% increase) or rapidly falling platelets (<100,000/μL) signals plasma leakage and increased DSS risk; these findings prompt more aggressive fluid resuscitation and consideration of platelet transfusion (if platelets <50,000/μL or if active bleeding). — AVOID ASPIRIN and NSAIDs: These increase bleeding risk. PARACETAMOL is the fever-management drug of choice (15 mg/kg Q4–6H, maximum 60 mg/kg/day). — BLEEDING PRECAUTIONS: Institute contact precautions, avoid unnecessary blood draws, use soft toothbrush, avoid IM injections (use IV or oral routes), monitor for bleeding signs. — REFERRAL: Any child with warning signs, severe dengue, or DSS must be referred to a secondary or tertiary facility immediately. Dengue shock syndrome is a medical emergency requiring ICU-level care, aggressive fluid resuscitation, vasopressor support (dopamine, dobutamine), and possible packed RBC or platelet transfusion. — COUNSELING: Educate caregivers on dengue transmission, *Aedes* habitat, and mosquito-reduction strategies. Teach recognition of warning signs and when to seek immediate care. PREVENTION ("DOH 4-S"): (1) **SEARCH AND DESTROY** breeding sites (empty containers, water storage, flower pots); (2) **SELF-PROTECTION** (wear long-sleeved shirts, use insect repellent containing DEET, install window screens); (3) **SEEK EARLY CONSULTATION** (report fever to healthcare provider promptly); (4) **SUPPORT FOGGING** (community-wide mosquito control during outbreaks). A dengue vaccine (Dengvaxia) is now available in the Philippines but is reserved for individuals with prior dengue infection (seropositive) due to risk of severe dengue in seronegative vaccinees.

Diarrhoeal disease (acute diarrhea: ≥3 loose/watery stools in 24 hours for <14 days; persistent: 14–29 days) remains a leading cause of death in children <5 years in the Philippines, particularly in low-resource settings. The primary danger is DEHYDRATION—loss of water and electrolytes from the intravascular space, leading to hypovolemia, shock, and death if untreated. While most cases of acute diarrhea are VIRAL (rotavirus, norovirus, adenovirus, enteroviruses), significant cases are BACTERIAL (*Enterotoxigenic E. coli* [ETEC], *Campylobacter*, *Salmonella*, *Shigella*) or PARASITIC (*Giardia*, *Entamoeba*). Malabsorption and insufficient food intake also contribute. The goal is rapid rehydration and continuation of feeding/breastfeeding to maintain nutrition and reduce illness duration. DEHYDRATION ASSESSMENT is the first critical nursing action. The nurse assesses and CLASSIFIES the degree of dehydration using clinical signs (per IMCI and WHO/DOH guidelines): **No Dehydration:** Child appears well; skin turgor normal (skin pinch goes back immediately); mucous membranes moist; eyes normal (not sunken); can drink normally; urine output normal; no signs of shock. **Some Dehydration:** ≥2 of the following: skin turgor abnormal (skin pinch goes back slowly over 1 second), mucous membranes dry, eyes sunken, unable to drink or drinks poorly, urine output decreased. **Severe Dehydration:** ≥2 of the following: skin turgor very abnormal (skin pinch goes back very slowly, >2 seconds), mucous membranes very dry, eyes very sunken, lethargic or unconscious, weak pulse or undetectable, low or undetectable BP, extremely cold extremities, deep/rapid breathing (compensatory for metabolic acidosis). IMCI DIARRHEA MANAGEMENT PLANS: **PLAN A — No Dehydration: HOME MANAGEMENT** — Give extra fluids plus ORS (WHO low-osmolarity ORS: sodium 75 mmol/L, glucose 75 mmol/L, potassium 20 mmol/L, chloride 65 mmol/L, citrate 10 mmol/L) after each loose stool. Recommended volumes: <1 year: 50 mL; 1–5 years: 100 mL per stool. — ZINC SUPPLEMENTATION: 10 mg once daily for infants <6 months; 20 mg once daily for children ≥6 months, for 10–14 days. Zinc reduces diarrhea duration by ~25% and recurrence by ~34%. — CONTINUE BREASTFEEDING if <2 years; do NOT restrict food. — Return immediately if child develops: persistent vomiting, inability to drink, increasing number of stools, blood in stool, signs of dehydration, or severe abdominal pain. **PLAN B — Some Dehydration: ORS THERAPY AT THE HEALTH FACILITY** — Supervised ORS rehydration: approximately **75 mL/kg body weight over 4 hours** using an IV pole (drop rate calculated) or frequent small spoonfuls (15 mL every 1–2 minutes) if child refuses bottle/cup. Formula: **Total volume (mL) = 75 mL/kg × body weight (kg)** Example: 12 kg child = 75 × 12 = 900 mL over 4 hours. — Monitor ongoing losses: if child vomits or has >5 mL/kg additional diarrhea during rehydration, give extra ORS 10 mL/kg and reassess. — After 4 hours, reassess child's hydration status: if dehydration has resolved, switch to Plan A home management; if still some dehydration, repeat ORS for another 4 hours; if severe dehydration has developed, switch to Plan C. — ZINC SUPPLEMENTATION (as above). — CONTINUE FEEDING: exclusive breastfeeding if <2 years; age-appropriate foods once the child can eat. — Counsel mother on ORS use at home and warning signs. **PLAN C — Severe Dehydration: IV REHYDRATION IMMEDIATELY** — Establish IV access (peripheral or central, depending on severity and availability). — **First bolus (30 minutes):** 100 mL/kg Ringer's lactate (or normal saline if Ringer's unavailable) IV over 30 minutes. Formula: **Volume = 100 mL/kg × body weight (kg) ÷ 0.5 hour** Example: 12 kg child = 100 × 12 ÷ 0.5 = 2400 mL over 30 minutes. — After first bolus, reassess: if signs of shock have resolved and child can drink, switch to Plan B (ORS) or Plan A. If shock persists, give second bolus (another 100 mL/kg over 30 minutes). — After rehydration, calculate ONGOING MAINTENANCE + ONGOING LOSSES (from stool, vomit, etc.). Maintenance formula: 50 mL/kg for first 10 kg + 20 mL/kg for next 10 kg + 1 mL/kg above 20 kg. Example: 12 kg child = (50 × 10) + (20 × 2) = 540 mL per 24 hours maintenance. Add: 10 mL/kg per diarrheal stool as replacement. — IV fluid rate is calculated and adjusted hourly based on reassessment. — Once child can drink, transition to ORS (Plan B or A) and oral feeding. — **ZINC SUPPLEMENTATION** (as above). — REFERRAL to a secondary facility if: signs of shock do not resolve after two boluses, severe malnutrition or visible blood in stool, age <6 months with severe dehydration, suspected cholera or typhoid (endemic areas). ADDITIONAL MANAGEMENT PRINCIPLES: — **CONTINUE FEEDING:** WHO/UNICEF/DOH guidelines strongly recommend continuation of age-appropriate feeding throughout diarrhea management. Feeding reduces stool output, improves nutrition, and shortens illness duration. Exclusive breastfeeding should continue if <2 years. Once the acute phase resolves, resumption of adequate feeding is critical to prevent malnutrition. — **ASSESSMENT FOR UNDERLYING CAUSE:** While most acute diarrhea is viral/self-limiting, assess for: (1) BLOODY DIARRHEA (suggests *Shigella*, *Salmonella*, or dysenteric diarrhea)—may require specific antibiotics; (2) PERSISTENT DIARRHEA (14–29 days)—higher risk of malnutrition and may require investigation; (3) SIGNS OF MALNUTRITION or EDEMA—suggest chronic malnutrition or PEM, increasing severity risk. — **INFECTION PREVENTION:** Teach handwashing after defecation and before eating/food preparation, safe water storage and treatment, and safe disposal of feces. These prevent transmission and reduce community burden. — **MONITORING:** Record all intake (fluid, food, IV) and output (stool, urine, vomit) meticulously. Check weight daily (if <5% loss, no dehydration; 5–10% loss, some dehydration; >10% loss, severe dehydration—can guide reassessment). Monitor vital signs (tachycardia, hypotension indicate inadequate rehydration). Watch for complications: secondary infection, electrolyte imbalance (hyponatremia, hyperkalemia), acute kidney injury (from severe dehydration), and malnutrition. — **MICRONUTRIENT SUPPLEMENTATION:** Beyond zinc, provide Vitamin A (100,000 IU for 6–11 months; 200,000 IU for ≥1 year) to reduce secondary infections and mortality, especially in malnourished children. ROTAVIRUS AND EPI SCHEDULE: Rotavirus vaccine is now part of the WHO/DOH EPI schedule (doses at 6, 10, 14 weeks) and has significantly reduced severe rotavirus diarrhea and hospitalizations in vaccinated populations.

The Integrated Management of Childhood Illness (IMCI) is a WHO/UNICEF-endorsed, DOH-adopted strategy designed to reduce under-5 mortality by improving the quality of care at the PRIMARY-CARE LEVEL, particularly at the Rural Health Units (RHUs) and barangay health stations. IMCI recognizes that a sick child often has multiple problems simultaneously (e.g., pneumonia + malnutrition + incomplete immunization) and that managing each problem in isolation is inefficient and ineffective. Instead, IMCI provides an integrated assessment and treatment approach for the most common childhood illnesses: PNEUMONIA, DIARRHEA, MALARIA (in endemic areas), MEASLES, MALNUTRITION, and ANEMIA. The IMCI FRAMEWORK is organized around THREE KEY COMPONENTS: (1) **CASE ASSESSMENT:** The nurse/frontline health worker uses a standardized checklist to assess the sick child quickly and systematically, asking key questions and performing focused physical examination. (2) **CLASSIFICATION:** Based on assessment findings, the child is classified into COLOR-CODED TRIAGE CATEGORIES that guide urgency of action: — **PINK (Urgent — REFER/HOSPITALISE):** Severe disease or general danger signs that require immediate referral or hospitalization. The child needs more advanced care than the primary-care facility can provide. — **YELLOW (Specific Treatment at the facility):** Signs of moderate disease that can be managed with specific treatment at the health facility (oral antibiotics, ORS, etc.) and home care advice. The child may need follow-up or referral if symptoms worsen. — **GREEN (Home Management):** Mild disease or no disease; child can be managed at home with advice to the caregiver. Follow-up within 3–5 days. (3) **TREATMENT & COUNSELLING:** Once classified, the nurse provides specific treatment (if indicated), practical advice on home care, and counseling on feeding, fluid, and when to return immediately. THE IMCI ASSESSMENT FOCUSES ON TWO AGE-BASED CHARTS: **YOUNG INFANT CHART (1 week – 2 months):** Because young infants deteriorate rapidly, IMCI assesses them differently. The chart checks for: — **Possible serious bacterial infection (PSBI):** fever (≥37.5°C) or low body temperature (<35.5°C), movement only with stimulation or no movement, convulsions, not feeding well, severe chest indrawing, moderate tachypnea (≥50/min). — **Jaundice** (physiologic vs. pathologic; breastfeeding failure jaundice). — **Diarrhea and dehydration:** assess using the young infant-specific Plan A/B/C. — **Feeding problems:** assess breastfeeding attachment, express, and position; correct feeding problems on the spot. — **Low weight:** screen for failure to thrive or underlying illness. — **Local bacterial infection:** skin/umbilical infection, purulent eye discharge. — **Malaria risk** (if endemic area and fever present). Danger signs in the young infant triggering PINK classification (urgent referral): **not feeding well, convulsions, fast breathing (≥60/min), severe chest indrawing, fever ≥37.5°C or hypothermia <35.5°C, movement only on stimulation or no movement, suspected meningitis (bulging fontanelle, neck stiffness).** **CHILD CHART (2 months – 5 years):** The main symptoms assessed are: 1. **Cough or Difficult Breathing:** Determine presence of cough/difficult breathing. If YES, count respiratory rate: — Assess for FAST BREATHING (tachypnea threshold varies by age: <2 mo ≥60, 2–12 mo ≥50, 12 mo–5 yr ≥40). — Assess for GENERAL DANGER SIGNS: not able to drink/breastfeed, vomits everything, convulsions or history of convulsions with this illness, lethargic/unconscious. — Assess for PNEUMONIA SIGNS: fast breathing or chest indrawing (lower chest wall draws in when child breathes in—indicates increased work of breathing, suggesting pneumonia or severe respiratory distress). — Assess for SEVERE PNEUMONIA/RESPIRATORY DISTRESS: stridor (high-pitched breathing sound, suggests laryngeal obstruction or croup), severe chest indrawing, nasal flaring, or grunting. — **CLASSIFICATION:** General danger signs → PINK (urgent refer). Chest indrawing → YELLOW (refer or treat with oral antibiotics + oxygen if available; follow up). Fast breathing alone → YELLOW (oral antibiotic). No fast breathing/chest indrawing, not able to drink → YELLOW (treat specific signs). None of above → GREEN (home care). 2. **Diarrhea:** Determine presence of diarrhea (≥3 loose stools in 24 hours). If YES: — **Assess for GENERAL DANGER SIGNS:** not able to drink, vomits everything, convulsions, lethargic/unconscious → PINK (urgent refer). — **Assess for BLOOD in STOOL:** if YES → YELLOW (dysentery; consider antibiotics if *Shigella* suspected). — **Assess DEHYDRATION USING IMCI SIGNS** (see above section): No dehydration → GREEN (Plan A home care). Some dehydration → YELLOW (Plan B ORS at facility). Severe dehydration → PINK (Plan C IV rehydration; urgent refer). — Provide ORS + ZINC (10–20 mg/day, 10–14 days) regardless of classification. — **CLASSIFICATION:** Severe dehydration or blood in stool → PINK. Some dehydration → YELLOW. No dehydration → GREEN. 3. **Fever:** Determine presence of fever (≥37.5°C). If YES: — **In MALARIA-ENDEMIC areas:** assess for malaria signs (fever, history of fever), perform malaria rapid diagnostic test (RDT) or microscopy. If malaria positive → YELLOW (specific antimalarial treatment at facility). — **Assess for MEASLES signs:** fever + rash + cough/coryza/conjunctivitis or Koplik spots → YELLOW (suspected measles; isolate, give Vitamin A). Or if the patient has any general danger sign (not able to drink, vomits everything, convulsions, lethargic) → PINK (refer). — **Assess for other fever causes:** malaria (endemic areas), meningitis (neck stiffness, altered consciousness), dengue (endemic areas, severe abdominal pain, bleeding, warning signs → PINK). — **CLASSIFICATION:** General danger signs + fever (suspected meningitis, severe dengue, etc.) → PINK. Suspected malaria/measles/other uncomplicated fever → YELLOW. Simple fever without other signs → GREEN (home care, monitor for warning signs). 4. **Ear Problem:** Assess ear pain, ear discharge. If present: → YELLOW (assess and treat; refer if severe, hearing loss, signs of mastoiditis). AFTER ASSESSING MAIN SYMPTOMS, CHECK FOR: — **Malnutrition:** poor weight gain, signs of acute malnutrition (wasting, edema), or chronic malnutrition (stunting). Refer for nutritional rehabilitation if severe; provide counseling on feeding. — **Anaemia:** pale palms, pale conjunctiva. Refer for evaluation; provide iron supplementation counseling. — **Immunisation Status:** Check whether child has received all EPI vaccines on schedule. If gaps, provide catch-up vaccination or refer for Garantisadong Pambata program. — **Feeding:** Breastfeeding status, age of introduction of solid foods, current diet. Provide counseling on appropriate feeding practices. GENERAL DANGER SIGNS (ANY ONE REQUIRES PINK CLASSIFICATION AND URGENT REFERRAL): — **Not able to drink or breastfeed** (suggests difficulty swallowing, altered consciousness, severe illness). — **Vomits everything** (suggests inability to maintain hydration, severe dehydration risk). — **Convulsions or history of convulsions with this illness** (suggests CNS involvement, high fever, electrolyte abnormality, or serious infection). — **Lethargic or unconscious** (abnormally sleepy, hard to wake, or unresponsive—suggests sepsis, shock, encephalitis, severe malaria, or other life-threatening condition). FAST-BREATHING CUT-OFFS (IMCI PNEUMONIA THRESHOLDS FOR RESPIRATORY RATE): — **<2 months: ≥60 breaths/minute** — **2 months – 12 months: ≥50 breaths/minute** — **12 months – 5 years: ≥40 breaths/minute** Counting respiratory rate: Count chest wall movements for a full minute (not for 15 seconds then multiply), because respiration in children is irregular. CHEST INDRAWING (lower chest wall drawing inward when breathing in) is a sign of SEVERE PNEUMONIA → YELLOW or PINK classification (depending on other signs); child requires oxygen, referral, and/or antibiotics. NURSING ROLE IN IMCI: The RHU nurse or frontline health worker is the **FIRST-LINE ASSESSOR** of the sick child. According to RA 9173, the nurse is mandated to assess, classify, provide first-line treatment, counsel caregivers, and decide on referral. The IMCI approach empowers the nurse to: — Quickly ASSESS the child using systematic, standardized questions and physical exam. — CLASSIFY the child accurately into PINK/YELLOW/GREEN based on findings. — Provide IMMEDIATE APPROPRIATE TREATMENT: give oral antibiotics (amoxicillin), ORS, Vitamin A, zinc, antipyretics as indicated, and oxygen if available. — MANAGE COMPLICATIONS: recognize danger signs early and act (referral, fluid resuscitation, etc.). — COUNSEL THE CAREGIVER: provide practical advice on home care (feeding, fluid, when to return immediately). — LINK THE CHILD TO HIGHER CARE: refer PINK cases urgently; arrange transportation; send a referral letter with key findings and actions taken. — MONITOR FOLLOW-UP: for YELLOW cases managed at the facility, re-assess after 2 days; for GREEN cases managed at home, counsel on return visit timing (3–5 days). — ENSURE PREVENTIVE CARE: administer catch-up vaccines, provide Vitamin A and deworming (Garantisadong Pambata), and counsel on feeding and infection prevention. IMCI STRENGTHENS the primary-care level by: — Reducing inappropriate/unnecessary referrals (GREEN cases managed at home, reducing facility burden). — Improving case detection and referral of truly sick children (PINK cases referred urgently, saving lives). — Standardizing assessment and treatment protocols (reducing variation in care quality). — Empowering frontline health workers (nurses, midwives) as capable first-line providers. — Reducing mortality and disability in children <5 years.

The DOH operates several evidence-based, population-level programs aimed at reducing childhood communicable diseases and malnutrition. As a graduate nurse in clinical practice, particularly in the RHU or Integrated Practice Unit (IPU), you will coordinate with and implement these programs. Understanding their components, schedules, and evidence base strengthens your role as a health advocate aligned with RA 9173's mandate for health promotion and disease prevention. EXPANDED PROGRAM ON IMMUNIZATION (EPI): The EPI is the DOH's cornerstone immunization program, providing free vaccines to all Filipino children. The schedule protects against the most common vaccine-preventable diseases: tuberculosis, hepatitis B, diphtheria, tetanus, pertussis, poliomyelitis, Haemophilus influenzae type b (Hib), measles, mumps, rubella, and pneumococcus. The Philippine EPI SCHEDULE is: **At Birth:** — BCG (Bacillus Calmette-Guérin): protects against tuberculosis (TB). Single dose IM. — Hepatitis B (HepB): first dose; second at 6 weeks, third at 6 months. **At 6 weeks (1.5 months):** — Pentavalent (DPT + Hib + HepB): diphtheria, tetanus, pertussis, Hib, hepatitis B. First dose IM. — Inactivated Polio Vaccine (IPV): first dose IM (or IV if IVR—intravenous access—is available, though this is uncommon). — Pneumococcal Conjugate Vaccine (PCV): first dose IM; protects against *Streptococcus pneumoniae*. — Rotavirus vaccine: oral (OV); first dose to prevent rotavirus gastroenteritis. **At 10 weeks:** — Pentavalent, IPV, PCV, rotavirus: second doses (same as 6-week schedule). **At 14 weeks:** — Pentavalent, IPV, PCV, rotavirus: third doses. **At 9 months:** — Measles-containing vaccine (MCV): single dose IM; protects against measles, mumps, rubella (this formulation in the Philippines is MR—measles/rubella—though MMR is available in private practice). **At 12 months:** — MCV: second dose IM (booster). **At 18 months:** — DPT booster (pentavalent booster for those who received pentavalent previously): IM. — IPV booster: IM. — Measles booster: IM (if not yet given). **At 4–6 years:** — DPT booster (final booster): IM. — IPV booster (final): IM. BEFORE VACCINE ADMINISTRATION, the nurse must perform **VACS** (Vaccine Adverse Events Screening): — **Vitamin A recent?** (If child received Vitamin A in last 4 weeks, live vaccines may be deferred.) — **Allergies?** (Anaphylaxis history to vaccine components; certain contraindications exist.) — **Convulsions or seizures history?** (Relative contraindication for whole-cell pertussis; acellular pertussis in pentavalent is safer.) — **Severe illness today?** (Defer non-urgent vaccines if child is ill; give if it's routine immunization day and child has only minor illness.) VACCINE STORAGE: Vaccines are heat-sensitive (live vaccines especially). The Cold Chain—from manufacture to administration—must be maintained at 2–8°C. The nurse ensures the vaccine carrier (VC) is properly maintained, uses ice packs (not dry ice), checks vaccine expiry dates and condition before use, and documents vaccine lot numbers. ADVERSE EVENTS FOLLOWING IMMUNIZATION (AEFI): The nurse counsels caregivers on common mild side effects (local reaction at injection site, mild fever) vs. severe adverse events (anaphylaxis, seizures). Mild events are monitored at home; severe events require immediate intervention and reporting to the DOH. GARANTISADO PAMBATA (GUARANTEED CHILD / GP) PROGRAM: GP is a biannual (every 6 months) door-to-door child health program implemented by RHUs and barangay health workers, reaching children 0–59 months in underserved communities. The package includes: 1. **VITAMIN A SUPPLEMENTATION:** — **Infants 6–11 months:** 100,000 IU once per year. — **Children 12–59 months:** 200,000 IU EVERY 6 MONTHS (i.e., twice per year during GP activities). — **Evidence:** Vitamin A reduces mortality by ~12–24%, reduces incidence of respiratory and diarrheal infections, and improves immune function. WHO/UNICEF recommends it as a cost-effective intervention. — **Given additionally:** All children with MEASLES receive Vitamin A on days 1, 2, and 2 weeks after diagnosis (regardless of GP schedule). — **Route:** Usually IM (retinyl palmitate formulation) or oral (retinol or retinyl acetate). Oral is easier for mass programs. 2. **DEWORMING:** — **Children 12–59 months:** Mebendazole or albendazole (single dose of 500 mg or weight-adjusted) every 6 months to prevent *Ascaris*, *Trichuris*, and hookworm infections that cause malnutrition and anemia. 3. **IMMUNISATION CATCH-UP:** — Children with incomplete/delayed EPI schedule receive catch-up doses. This "recovers" children who missed earlier doses due to lack of access, parental hesitation, or other barriers. 4. **HEALTH EDUCATION:** — Counseling on nutrition, infant feeding (exclusive breastfeeding for 6 months, then complementary foods), sanitation, handwashing, and warning signs of common childhood illnesses. GP STRENGTHENS the primary-care level by: — Reaching underserved populations (rural, urban poor) who may not regularly attend RHUs. — Providing preventive micronutrients and deworming at scale. — Identifying malnourished or ill children for referral and follow-up. — Improving community awareness of child health practices. NURSING IMPLEMENTATION OF EPI AND GP: The nurse: — **Maintains the vaccine cold chain:** ensures proper storage at 2–8°C, monitors refrigerator temperatures, checks expiry dates, uses vaccine carriers correctly during outreach. — **Performs VACS screening** before administering vaccines. — **Administers vaccines correctly:** sterile technique, correct route/site, correct volume, aspiration (as per protocol), gentle handling. — **Keeps accurate records:** documents date, vaccine name, lot number, expiry date, site, route, adverse events, and caregiver education in the child's health booklet (or health center registry). — **Counsels caregivers:** explains what vaccines are given, why, common side effects, when to return, and where to go if AEFI occurs. — **Organizes and conducts GP activities:** coordinates with barangay health workers, schedules house-to-house visits, mobilizes community, arranges transportation of vaccines and supplies, monitors for adverse events, and documents coverage. — **Monitors coverage and dropout rates:** identifies children with incomplete schedules and follows up (tracing defaulters). — **Reports to DOH:** submits monthly immunization performance data (doses given, coverage %, AEFI reports) to the local health office for program monitoring and evaluation.

In managing communicable diseases in children, nurses use the NURSING PROCESS—assessment, diagnosis, planning, implementation, and evaluation—aligned with NANDA International nursing diagnoses, standardized taxonomies (including those in the Philippines' National Nursing Core Curricula), and the scope of practice defined in RA 9173 (The Philippine Nursing Act of 2002). The nurse acts as an independent practitioner within the scope of nursing, a dependent practitioner collaborating with the physician, and an interdependent practitioner with the interprofessional team. COMMON NURSING DIAGNOSES IN PAEDIATRIC COMMUNICABLE DISEASES: 1. **Risk for Infection Transmission** (related to airborne/droplet/contact precautions not maintained; evidenced by potential to spread disease to susceptible contacts). — Interventions: Implement appropriate isolation precautions (airborne, droplet, contact as indicated); educate child and caregivers on cough/sneeze etiquette; restrict non-immune visitors; use PPE correctly; hand hygiene; cohort patients with same illness if isolation room unavailable; ensure proper ventilation; clean environmental surfaces; dispose of contaminated materials safely. — Outcome: Child and contacts are protected from disease transmission; infection control measures are adhered to. 2. **Hyperthermia** (related to systemic inflammatory response to viral/bacterial infection; evidenced by elevated body temperature, flushed skin, profuse diaphoresis). — Interventions: Assess temperature q2–4H (or continuously if high risk); maintain tepid environment and cool linens; give antipyretics as prescribed (paracetamol); encourage light clothing; promote fluid intake; apply cool compress to areas of heat dissipation (groin, axilla, forehead); monitor for febrile convulsions in young children; educate caregiver on fever management at home. — Outcome: Body temperature returns to normal range; child is comfortable; risk of febrile complications is minimized. 3. **Acute Pain** (related to inflammation, mucosal lesions, muscle/joint aches, photophobia; evidenced by child's cry, grimace, reluctance to move, inability to sleep). — Interventions: Assess pain using age-appropriate pain scale; administer analgesics as prescribed; position for comfort; apply warm/cool compresses as tolerated; reduce environmental stimuli (dim lights for photophobia, quiet for headache); distraction techniques; reassurance; educate caregiver on non-pharmacologic pain relief (positioning, gentle handling, soft music). — Outcome: Child reports or demonstrates pain relief; able to rest, eat, and engage in activities of daily living. 4. **Imbalanced Nutrition: Less Than Body Requirements** (related to anorexia, vomiting, dysphagia, post-tussive vomiting; evidenced by poor intake, weight loss, weak suck, lethargy). — Interventions: Assess nutritional status and intake; offer small, frequent, age-appropriate meals; avoid triggers (sour foods in mumps, hard foods in diphtheria); encourage breastfeeding if <2 years (especially in diarrhea); provide favorite foods if appropriate; use supplemental high-calorie fluids (broths, milk); monitor I&O and weight; refer for NG feeding if unsafe swallowing or inability to maintain intake; counsel caregiver on continued feeding during illness. — Outcome: Child maintains or regains appropriate weight; nutritional intake is adequate; growth is sustained. 5. **Impaired Skin Integrity** (related to pruritic vesicles in varicella, scratching, secondary infection; evidenced by open lesions, presence of crusts, signs of superinfection). — Interventions: Assess skin status and infection signs; keep nails short; apply antihistamines; use soft mittens or wrap hands if scratching is severe; give cool/tepid baths or calamine lotion applications; teach non-scratching; monitor for signs of secondary bacterial infection (warmth, pus, spreading redness); apply antimicrobial ointment to lesions; counsel caregiver on hygiene and prevention of spread. — Outcome: Skin lesions heal without complications; secondary infection does not develop; child refrains from scratching. 6. **Deficient Fluid Volume** (related to diarrhea, vomiting, fever; evidenced by decreased urine output, dry mucous membranes, sunken eyes, poor skin turgor, weak pulse, hypotension). — Interventions: Assess hydration status q1–2H; establish IV access if severe dehydration; administer fluids per IMCI Plan (ORS, IV fluid) as prescribed; monitor I&O meticulously (record all intake sources and urine/stool/vomit output); weigh daily; monitor vital signs; reassess hydration status regularly; educate caregiver on ORS use and when to seek urgent care; promote oral intake once tolerated; avoid excessive fluid restriction (child needs hydration). — Outcome: Hydration status improves; vital signs stabilize; urine output is adequate; child's weight stabilizes. 7. **Ineffective Airway Clearance** (related to excessive mucus, laryngeal edema, pseudomembrane, severe cough/paroxysm; evidenced by stridor, grunting, nasal flaring, cyanosis, altered breathing pattern). — Interventions: Position upright or semi-recumbent; suction gently as needed (avoid aggressive suctioning which triggers apnea); provide humidified oxygen; monitor respiratory rate and effort q1–2H; keep emergency airway equipment (endotracheal tubes, laryngoscope, tracheostomy tray) available; monitor for signs of respiratory distress (increased WOB, stridor, lethargy); prepare for possible intubation; avoid neck flexion (maintain airway); counsel caregiver to keep child calm (distress worsens airway obstruction). — Outcome: Airway remains patent; respiratory rate is within age-appropriate range; oxygen saturation is adequate; child has effective breathing pattern. 8. **Risk for Delayed Development** (related to chronic effects of severe communicable disease, malnutrition, frequent hospitalization; evidenced by potential for developmental delays, hearing loss post-meningitis/mumps, learning difficulties). — Interventions: Provide early developmental screening; refer to developmental specialists if concerns; encourage age-appropriate play and learning; involve caregivers in home stimulation activities; ensure micronutrient supplementation (Vitamin A, zinc); counsel on continued feeding and cognitive stimulation; follow-up post-illness to assess for complications (e.g., hearing assessment after mumps/meningitis). — Outcome: Child achieves developmental milestones; hearing, vision, and cognitive function are within normal limits; family engages in developmental promotion. 9. **Deficient Knowledge (Parent/Caregiver)** (related to unfamiliarity with disease transmission, prevention, home care, warning signs; evidenced by asking questions, expressing confusion, non-compliance with instructions). — Interventions: Assess caregiver's understanding; provide clear, culturally appropriate health education (use local language, visual aids); explain disease transmission and isolation practices; teach recognition of warning signs and when to seek urgent care; demonstrate home care skills (ORS preparation, medication administration, hygiene); provide written materials (in local language); involve caregiver in child's care; reinforce with repetition; answer questions patiently; arrange follow-up teaching. — Outcome: Caregiver demonstrates understanding of disease, prevention, home care, and warning signs; complies with health advice; feels confident caring for the child at home. 10. **Risk for Complications** (related to severe infection, immunosuppression, or specific disease complications; e.g., myocarditis in diphtheria, orchitis in mumps, Reye syndrome in varicella, apnea in pertussis; evidenced by risk factors present). — Interventions: Assess risk factors; monitor continuously for early signs (cardiac rhythm in diphtheria, testicular swelling in mumps, lethargy/vomiting in Reye syndrome, apnea episodes in pertussis); educate caregiver on danger signs; have emergency equipment available; refer urgently if complications develop; provide supportive care; document all findings meticulously. — Outcome: Complications are detected early or prevented; child receives timely intervention; mortality and morbidity are minimized. RA 9173 PROFESSIONAL ACCOUNTABILITY: Underage RA 9173 (The Philippine Nursing Act of 2002), nurses are accountable for: — **Licensure and Competence:** Holding a valid PRC nursing license and maintaining competence through continuing education. Preparing for and passing the NLE ensures entry-level competency in all nursing domains, including paediatric communicable disease management. — **Scope of Practice:** Nursing includes health promotion, disease prevention, curative care, and rehabilitation. In communicable diseases, nurses assess, diagnose, plan, implement, and evaluate nursing care; administer medications and vaccines; perform isolation and infection control; counsel patients and families; and make referral decisions within their scope. — **Informed Consent and Patient Rights:** Before administering vaccines or treatments, the nurse obtains informed consent (or assent from the child if age-appropriate, with parental consent). The nurse respects the child's and family's autonomy, privacy, and dignity, and protects confidentiality of health information. — **Documentation:** All nursing care—assessment findings, diagnoses, interventions, outcomes, and patient/family education—must be accurately and timely documented in the child's health record. This ensures continuity of care, supports accountability, and serves as a legal record. In communicable diseases, documenting infection control measures, vaccine lot numbers, AEFI, and referral details is critical. — **Collaboration and Referral:** While nurses are independent practitioners in assessment and diagnosis, they collaborate with physicians and other interprofessional team members in treatment and referral decisions. The nurse makes referral decisions based on IMCI criteria (PINK cases) and communicates urgently with the receiving facility. The nurse ensures the child's continuity of care across levels of the health system. — **Professional Ethics and Standards:** The nurse adheres to ethical principles (autonomy, beneficence, non-maleficence, justice), the Code of Ethics for Filipino Nurses, and evidence-based practice standards (IMCI, EPI, DOH protocols). The nurse advocates for vulnerable populations (children, poor families) and ensures equitable access to care. — **Reporting and Surveillance:** Communicable diseases are reportable to the DOH. The nurse reports cases of measles, pertussis, diphtheria, dengue, and other notifiable diseases within the required timeframe, contributing to disease surveillance and outbreak response. — **Competence in Emerging Issues:** The nurse stays updated on new vaccines, protocols, and disease trends (e.g., dengue serotypes, antimicrobial resistance patterns). The nurse can critically appraise evidence and adapt practice as guidelines evolve. NURSING AS AN ADVOCATE: Beyond the clinical nursing diagnoses and interventions, the nurse serves as an ADVOCATE for child health: — **Health Promotion:** Educate communities on immunization importance, dengue prevention, safe water access, sanitation, and nutrition. — **Disease Prevention:** Promote vaccination uptake; support Garantisadong Pambata and other preventive programs; advocate for environmental improvements. — **Policy Advocacy:** Support evidence-based child health policies; engage in health legislation discussions; advocate for adequate health budgets and resources for child health programs. — **Equity:** Ensure that underserved, marginalized children have access to preventive and curative services; advocate for the removal of barriers (cost, distance, cultural beliefs) to care.
