NLE items on Tet spells almost always ask for PRIORITY. The knee-chest position is the single most tested answer here. Oxygen and morphine are adjuncts — always lead with positioning.

Model Answer

The priority nursing intervention during a Tet spell is to place the infant in the KNEE-CHEST position (or encourage squatting in older children) to increase systemic vascular resistance and reduce the right-to-left shunt.

Examiner Tip

Use a two-column approach mentally: epiglottitis on one side, croup on the other. Examiners reward contrast — directly comparing the two conditions earns more marks than describing them separately.

Model Answer

Epiglottitis is a bacterial emergency (classically caused by Haemophilus influenzae type b) characterised by the '4 D's': Drooling, Dysphagia, Dysphonia (muffled voice), and Distress, along with high fever and a 'thumb sign' on lateral neck X-ray. The child sits in a tripod/sniffing position and appears toxic. Croup (laryngotracheobronchitis) is viral (parainfluenza), characterised by a barking or seal-like cough, inspiratory stridor, and hoarseness — usually worse at night — with a 'steeple sign' on X-ray. Fever is low-grade.

The word 'APICAL' and the specific number (90–100 bpm for infants, 70 bpm for older children) are what examiners look for. Students who write 'check pulse' without specifying apical and the threshold lose the mark.

Model Answer

Before administering digoxin to the infant, the nurse must: 1. Count the APICAL pulse for a full one minute. Hold the dose and notify the physician if the apical heart rate is less than 90–100 beats per minute (bpm) in an infant. 2. Assess for signs of digoxin toxicity, including bradycardia, vomiting/nausea, anorexia, and dysrhythmias, before each dose.

Examiner Tip

The phrase 'cyanosis not relieved by oxygen' is a high-yield examiner trigger phrase. Include it when describing cyanotic CHD to demonstrate clinical understanding beyond memorisation.

Model Answer

Acyanotic defects involve a LEFT-TO-RIGHT shunt, where oxygenated blood recirculates to the lungs. The child is not cyanotic initially but is at risk for congestive heart failure and pulmonary overcirculation. Example: Ventricular Septal Defect (VSD). Cyanotic defects involve a RIGHT-TO-LEFT shunt, where deoxygenated blood bypasses the lungs and enters systemic circulation, causing cyanosis that is NOT relieved by oxygen administration. Example: Tetralogy of Fallot (TOF).

The fever in Kawasaki disease must be stated as '>5 days' and 'unresponsive to antipyretics' — both qualifiers are tested. The complication is specifically coronary ARTERY ANEURYSM, not simply cardiac disease. Be specific.

Model Answer

Kawasaki disease is an acute vasculitis of unknown cause affecting children typically under 5 years of age. Three classic signs are: 1. High fever lasting more than 5 days, unresponsive to antipyretics 2. Bilateral non-purulent (non-infectious) conjunctivitis 3. 'Strawberry' tongue with cracked, red, swollen lips (Other accepted signs: polymorphous rash, cervical lymphadenopathy, swelling and redness of hands and feet followed by desquamation/peeling) The most feared cardiac complication is CORONARY ARTERY ANEURYSM, which can lead to thrombosis, myocardial infarction, or sudden death.

Model Answer

ACUTE ASTHMA ATTACK — NURSING MANAGEMENT I. PRIORITY ASSESSMENT (Airway, Breathing, Circulation) The nurse immediately assesses the child's respiratory status: rate, depth, use of accessory muscles, retractions, and the presence and quality of breath sounds. NOTE: A 'silent chest' (no audible wheeze despite severe distress) is an OMINOUS sign indicating near-total airway obstruction and impending respiratory failure — this is an airway emergency. Also assess oxygen saturation (SpO2), level of consciousness, skin colour (pallor or cyanosis), and ability to speak in full sentences. II. PRIORITY NURSING DIAGNOSES (NANDA) - Ineffective Airway Clearance related to bronchospasm, mucosal edema, and increased mucus production - Impaired Gas Exchange related to airflow obstruction - Anxiety related to respiratory distress (child and family) III. NURSING INTERVENTIONS 1. Position the child in HIGH FOWLER'S or an upright position to maximise lung expansion and reduce work of breathing. 2. Administer HUMIDIFIED OXYGEN as ordered to maintain SpO2 ≥95%. 3. Establish IV access and administer IV fluids to maintain hydration and liquefy secretions. 4. Monitor vital signs and SpO2 continuously; report deterioration immediately. 5. Keep the child calm and reduce anxiety — anxiety increases oxygen demand and worsens bronchospasm. Allow a parent to stay at the bedside. 6. Have emergency resuscitation equipment available at the bedside. IV. PHARMACOLOGICAL MANAGEMENT - SHORT-ACTING BETA-2 AGONIST (SABA) — Salbutamol (Albuterol): The FIRST-LINE RELIEVER drug. Given via nebuliser or metered-dose inhaler (MDI) with spacer. It causes bronchodilation by relaxing bronchial smooth muscle. Side effects include tachycardia and tremor — monitor heart rate. - SYSTEMIC CORTICOSTEROIDS (oral or IV prednisolone/methylprednisolone): Reduce airway inflammation. Given for moderate-to-severe attacks or those not responding to salbutamol. - IPRATROPIUM BROMIDE: Anticholinergic bronchodilator used as an adjunct with salbutamol in severe attacks. - OXYGEN: Delivered via face mask or nasal cannula based on severity and SpO2. V. EVALUATION The nurse evaluates effectiveness by monitoring for decreased retractions and accessory muscle use, normalising respiratory rate, improved SpO2, clearing of wheeze, and the child's ability to speak and feed comfortably.

Examiner Tip

The NLE often tests CONTRAINDICATED actions post-cleft repair. 'Never prone' after lip repair and 'nothing hard in the mouth' after palate repair are the two most tested post-op nursing points.

Model Answer

1. POSITIONING: After cleft LIP repair, the infant is positioned SUPINE or on the SIDE — NEVER prone — to prevent rubbing and trauma to the suture line. After cleft PALATE repair, positioning is also supine/side-lying and the same rationale applies. 2. ORAL RESTRICTIONS: After cleft LIP repair, no hard objects should contact the mouth; the use of a regular spoon or utensils near the suture line is avoided, and elbow (no-no) restraints are applied. After cleft PALATE repair, restrictions are stricter: NO STRAWS, NO PACIFIERS, NO SPOONS, and NO SUCTION CATHETERS near the repair site; the child is fed with a cup or the side of a spoon, and a SOFT or LIQUID DIET is maintained.

Patent Ductus Arteriosus (PDA)

Difficulty

medium

Template Id

T10

Examiner Tip

The indomethacin vs. prostaglandin E1 distinction is a classic NLE trap. Examiners love asking 'which drug closes the PDA' or 'which drug is given to keep the ductus open.' Know both and the reason for each.

Model Answer

Patent Ductus Arteriosus (PDA) is a congenital heart defect in which the ductus arteriosus — a fetal blood vessel connecting the pulmonary artery to the aorta — fails to close after birth. This results in a left-to-right shunt where oxygenated blood from the aorta flows back into the pulmonary artery, causing pulmonary overcirculation. Hallmark murmur: PDA produces a MACHINE-LIKE (continuous, machinery) murmur heard throughout systole and diastole, along with BOUNDING PULSES and WIDENED PULSE PRESSURE due to the continuous shunting of blood. Pharmacological closure: INDOMETHACIN (an NSAID/prostaglandin inhibitor) or IBUPROFEN is administered to promote closure of the PDA by inhibiting prostaglandin synthesis — prostaglandins naturally keep the ductus open. If pharmacological closure fails, surgical or catheter-based ligation is performed. IMPORTANT CONTRAST: In duct-dependent congenital heart lesions (e.g., Transposition of the Great Arteries), PROSTAGLANDIN E1 is administered to KEEP the ductus OPEN until corrective surgery.

Template Id

T11

Examiner Tip

For this topic, the contraindicated action (tongue depressor) with its specific rationale (laryngospasm) is where many students lose a mark. Examiners want the 'why' — always pair contraindicated actions with their clinical rationale.

Model Answer

EPIGLOTTITIS — PATHOPHYSIOLOGY, CLINICAL PRESENTATION, AND PRIORITY NURSING MANAGEMENT I. PATHOPHYSIOLOGY Epiglottitis is an acute bacterial infection of the epiglottis and surrounding supraglottic structures, classically caused by Haemophilus influenzae type b (Hib) — now rare in areas with Hib vaccination coverage. The infection causes rapid inflammation, swelling, and edema of the epiglottis, leading to partial or complete obstruction of the upper airway. It is a LIFE-THREATENING MEDICAL EMERGENCY that can cause total airway obstruction and death within minutes. II. CLINICAL SIGNS — THE '4 D's' - Drooling (cannot swallow secretions due to throat pain and obstruction) - Dysphagia (severe difficulty swallowing) - Dysphonia (muffled, 'hot potato' voice due to epiglottic swelling) - Distress (the child appears toxic, anxious, and in severe respiratory distress) Additionally: HIGH FEVER (sudden onset), TRIPOD/SNIFFING POSITION (child leans forward on hands, chin forward, mouth open to maximise airway), INSPIRATORY STRIDOR, and a 'THUMB SIGN' on lateral neck X-ray (swollen epiglottis resembling a thumb). III. PRIORITY NURSING ACTIONS 1. MAINTAIN AIRWAY PATENCY — This is the ABCs first priority. Keep the child calm and allow the child to maintain the position of comfort (tripod position). Do NOT force the child to lie down. 2. ALLOW PARENT TO STAY — keeping the child calm is critical; agitation increases oxygen demand and can precipitate complete obstruction. 3. ADMINISTER HUMIDIFIED OXYGEN gently — avoid any frightening procedures. 4. PREPARE FOR EMERGENCY AIRWAY MANAGEMENT — have intubation equipment, laryngoscope, and tracheostomy tray at the bedside. Notify anaesthesia/physician immediately. 5. Administer IV antibiotics as ordered (e.g., ceftriaxone) to treat the bacterial cause. IV. NEVER DO: DO NOT INSPECT THE THROAT WITH A TONGUE DEPRESSOR RATIONALE: Inserting a tongue depressor or attempting to visualise the throat (pharyngoscopy) in a child with suspected epiglottitis can trigger a LARYNGOSPASM — a sudden total closure of the already-inflamed and swollen larynx — resulting in COMPLETE AIRWAY OBSTRUCTION and respiratory arrest. Similarly, throat cultures, nasopharyngeal swabs, and forced positioning must all be avoided until a controlled airway is secured in an OR setting. V. EVALUATION Successful management is indicated by patent airway, improving oxygen saturation, decreasing fever with antibiotic therapy, and the child's ability to breathe comfortably without signs of obstruction.

Examiner Tip

Rheumatic fever questions in the NLE almost always test TWO things: the trigger (untreated GABHS strep) and the prevention (complete penicillin course). Emphasise that the disease is autoimmune — the bacteria themselves do not directly cause the heart damage; the immune response does.

Model Answer

Rheumatic Fever is an AUTOIMMUNE INFLAMMATORY DISEASE that develops as a complication of UNTREATED or inadequately treated GROUP A BETA-HEMOLYTIC STREPTOCOCCAL (GABHS) PHARYNGITIS ('strep throat'), typically occurring 1–5 weeks after the infection. It most commonly affects school-age children. Most important prevention strategy: COMPLETE the FULL COURSE of ANTIBIOTIC THERAPY (penicillin) for streptococcal pharyngitis. Nurses must educate families that stopping the antibiotic early — even when the child feels better — allows streptococcal bacteria to persist and trigger an autoimmune response. Long-term prophylactic penicillin is also given to prevent recurrence in affected children. Most serious cardiac complication: CARDITIS (inflammation of the heart) can lead to RHEUMATIC HEART DISEASE — permanent valvular damage, most commonly affecting the MITRAL VALVE — which can result in mitral stenosis or regurgitation causing chronic heart failure.

The NLE frequently tests the palivizumab distinction — is it treatment or prophylaxis? Always state it is PROPHYLAXIS. Also, stating 'hand hygiene' alone without mentioning contact precautions (gown, gloves, private room/cohorting) is insufficient for full infection control marks.

Model Answer

BRONCHIOLITIS IN INFANTS — CLINICAL PRESENTATION, MANAGEMENT, AND INFECTION CONTROL I. DEFINITION AND CAUSATIVE ORGANISM Bronchiolitis is an acute lower respiratory tract infection causing inflammation of the BRONCHIOLES, occurring predominantly in infants UNDER 2 YEARS of age (peak incidence at 2–6 months). It is most commonly caused by RESPIRATORY SYNCYTIAL VIRUS (RSV), which is highly contagious and spreads via DROPLET and CONTACT transmission. II. CLINICAL PRESENTATION - Prodromal upper respiratory symptoms (runny nose, low-grade fever) progressing to: - WHEEZING (caused by bronchiolar edema and mucus obstruction) - TACHYPNEA (fast breathing: ≥60/min if <2 months, ≥50/min if 2–12 months) - RETRACTIONS (intercostal, subcostal) and NASAL FLARING - COPIOUS NASAL SECRETIONS and COUGH - POOR FEEDING due to respiratory effort and nasal congestion - In severe cases: cyanosis, apnea, lethargy — LATE AND OMINOUS SIGNS requiring immediate intervention III. PRIORITY NURSING DIAGNOSES - Ineffective Airway Clearance related to bronchiolar inflammation and excessive secretions - Impaired Gas Exchange related to airflow obstruction from edema and mucus - Imbalanced Nutrition: Less Than Body Requirements related to difficulty feeding IV. NURSING INTERVENTIONS 1. SUCTIONING (bulb syringe or nasal aspirator) — PRIORITY to clear secretions and maintain airway patency before feeding and PRN. 2. POSITIONING — elevate the head of the bed (30–45 degrees) to reduce work of breathing. 3. ADMINISTER HUMIDIFIED OXYGEN as ordered — monitor SpO2 continuously. 4. HYDRATION — ensure adequate fluid intake; IV fluids if oral intake is inadequate; monitor I&O. 5. SMALL, FREQUENT FEEDINGS — feed in small amounts slowly to reduce aspiration risk and conserve energy. 6. CONTINUOUS MONITORING — respiratory rate, SpO2, level of consciousness, and feeding tolerance. V. INFECTION CONTROL — CRITICAL RSV is HIGHLY CONTAGIOUS. Strict CONTACT PRECAUTIONS must be implemented: - PRIVATE ROOM or COHORTING of RSV-positive infants - GOWN and GLOVES for all direct patient contact - RIGOROUS HAND HYGIENE before and after all patient contact — this is the single most effective infection prevention measure - Limit visitors and educate caregivers about transmission VI. PHARMACOLOGICAL PROPHYLAXIS PALIVIZUMAB (Synagis) is a humanised monoclonal antibody given as MONTHLY INTRAMUSCULAR INJECTIONS during RSV season as PROPHYLAXIS in high-risk infants (premature infants, infants with congenital heart disease or chronic lung disease). IMPORTANT: Palivizumab is PREVENTIVE, NOT a treatment for active RSV infection. VII. EVALUATION Effective management is evidenced by clearing of secretions, improved respiratory rate within age-appropriate range, SpO2 ≥95%, improved feeding tolerance, and absence of signs of respiratory failure.

Remember the mnemonic 'PROVED': Pulmonary stenosis, Right ventricular hypertrophy, Overriding aorta, VSD, Enlarged right ventricle — though the standard four are sufficient. Boot-shaped heart is a one-mark gift — never omit it.

Model Answer

Tetralogy of Fallot (TOF) is the most common CYANOTIC congenital heart defect, consisting of FOUR structural abnormalities: 1. PULMONARY STENOSIS — narrowing of the pulmonary valve/outflow tract, obstructing blood flow to the lungs 2. VENTRICULAR SEPTAL DEFECT (VSD) — an opening between the right and left ventricles 3. OVERRIDING AORTA — the aorta is positioned over the VSD, straddling both ventricles 4. RIGHT VENTRICULAR HYPERTROPHY (RVH) — the right ventricle hypertrophies due to increased workload from pulmonary stenosis Cyanosis occurs because PULMONARY STENOSIS increases resistance to blood flow into the lungs, causing deoxygenated blood from the right ventricle to shunt THROUGH the VSD into the aorta (right-to-left shunt). This deoxygenated blood enters systemic circulation, causing persistent cyanosis that is NOT relieved by supplemental oxygen alone. Chest X-ray shows a characteristic BOOT-SHAPED HEART (coeur en sabot) due to right ventricular hypertrophy.

CONGESTIVE HEART FAILURE (CHF) IN AN INFANT — PRIORITY NURSING INTERVENTIONS Clinical Context: A 6-month-old infant with a large VSD develops CHF due to pulmonary overcirculation from the left-to-right shunt, resulting in the heart being unable to meet the body's metabolic demands. PRIORITY NURSING DIAGNOSES (NANDA) - Decreased Cardiac Output related to structural heart defect and impaired myocardial contractility - Activity Intolerance related to imbalance between oxygen supply and demand - Imbalanced Nutrition: Less Than Body Requirements related to increased metabolic demands and fatigue during feeding - Excess Fluid Volume related to sodium and water retention from CHF FOUR PRIORITY NURSING INTERVENTIONS: 1. ASSESS AND MONITOR FOR SIGNS OF CHF (Assessment Priority) Monitor apical heart rate, respiratory rate, and rhythm continuously. Assess for hallmark infant CHF signs: tachycardia, tachypnea, feeding difficulty/diaphoresis with feeds, poor weight gain, hepatomegaly, and periorbital edema. Perform DAILY WEIGHT measurement at the same time on the same scale — weight gain of >50 g/day or >1 kg/week in an infant indicates fluid retention. RATIONALE: Early detection of worsening CHF allows for timely medical intervention before decompensation occurs. 2. CLUSTER NURSING CARE AND PROMOTE REST (Activity Conservation) Organise all assessments, procedures, and care activities together with planned rest periods. Handle the infant gently and minimise unnecessary stimulation. Elevate the HEAD OF THE BED (30–45 degrees) or use an infant seat. RATIONALE: Clustered care reduces oxygen consumption and cardiac workload. Elevated positioning decreases venous return to the heart, reduces preload, and improves respiratory effort by allowing the diaphragm to descend. 3. FACILITATE ENERGY-CONSERVING FEEDING Offer SMALL, FREQUENT FEEDINGS every 2–3 hours. Use a SOFT, ENLARGED or CROSS-CUT NIPPLE to minimise the effort required to suck. Limit each feeding session to a MAXIMUM of 20–30 MINUTES. If the infant becomes diaphoretic, tachypneic, or tachycardic during feeding, stop and allow rest. Consider NG tube feedings if oral intake is inadequate. RATIONALE: Feeding is the most energy-demanding activity for an infant with CHF. Fatigue during feeds results in inadequate caloric intake and failure to thrive — small, efficient feeds preserve energy while meeting nutritional needs. 4. ADMINISTER MEDICATIONS SAFELY — DIGOXIN AND DIURETICS a) DIGOXIN: Count the APICAL PULSE for a FULL ONE MINUTE before each dose. HOLD the dose and notify the physician if the apical HR is <90–100 bpm in this infant. Assess for toxicity signs (bradycardia, vomiting, anorexia, dysrhythmias) before administration. b) FUROSEMIDE (diuretic): Administer as ordered to reduce fluid overload. Monitor electrolytes, especially POTASSIUM — hypokalemia potentiates digoxin toxicity. Strict INTAKE AND OUTPUT monitoring. RATIONALE: Digoxin increases myocardial contractility and improves cardiac output; diuretics reduce preload by eliminating excess fluid. Safe administration of digoxin is a critical nursing responsibility under RA 9173 (Safe Nursing Practice standards). EVALUATION Effective management is demonstrated by: stable apical rate within age-appropriate range, improved feeding tolerance without diaphoresis, stable or decreasing weight (fluid loss), no hepatomegaly, decreased retractions, and improved SpO2.

Scoring Breakdown

Common Mark Deductions

• Writing 'monitor vital signs' without specifying which signs and thresholds to watch for
• Not specifying the digoxin apical pulse hold parameter (<90–100 bpm for infants)
• Omitting the energy-conserving feeding approach — this is a hallmark CHF infant care intervention
• Not connecting hypokalemia (from diuretic use) to increased digoxin toxicity risk
• Using adult CHF assessment parameters without adapting to infant presentation
