Pediatric Asthma Exacerbation with Suspected Viral Trigger
A 7-year-old girl, 25 kg, with a history of mild persistent asthma, presents to the emergency department with increased work of breathing, audible wheeze, and a dry cough. She has had a runny nose and low-grade fever for 2 days. Her mother reports she has used her albuterol inhaler (90 mcg/actuation) 6 puffs in the last 4 hours without relief. In the ED, her respiratory rate is 32/min, SpO2 91% on room air, heart rate 130 bpm, temperature 38.1°C. She is speaking in short phrases, with suprasternal retractions and nasal flaring. Breath sounds are diminished with expiratory wheeze. Peak expiratory flow (PEF) is 50% of personal best. The ED physician orders albuterol 2.5 mg nebulized every 20 minutes for 3 doses, ipratropium 0.5 mg nebulized once, and oral prednisolone 2 mg/kg (max 60 mg). The nurse must prioritize care.

Immediate assessment: 1) Airway and breathing: Assess respiratory rate, depth, effort (retractions, nasal flaring), breath sounds, and SpO2 continuously. Note ability to speak and mental status. 2) Circulation: Heart rate (tachycardia may be due to albuterol and hypoxia), perfusion, and blood pressure. 3) Disability: Level of consciousness, anxiety, and fatigue. 4) Exposure: Temperature and signs of infection.
Interventions in priority order: 1) Position for comfort: Upright or high-Fowler's to ease breathing. 2) Administer oxygen: Titrate to maintain SpO2 ≥ 94% (some guidelines say ≥ 90%, but for children, 94% is often targeted). Use nasal cannula or face mask. 3) Administer bronchodilators: Give albuterol nebulization as ordered (2.5 mg) with ipratropium 0.5 mg. Use a mouthpiece or mask; ensure proper technique. Monitor response (decreased wheeze, improved SpO2, decreased RR). 4) Administer corticosteroid: Give oral prednisolone 2 mg/kg = 50 mg (since 25 kg × 2 = 50 mg, within max 60 mg). Rationale: Steroids reduce airway inflammation; onset takes hours but early administration is key. 5) Monitor for deterioration: Watch for silent chest, decreasing respiratory effort, fatigue, or rising PaCO2 (if available). Prepare for possible escalation (e.g., magnesium sulfate, terbutaline, or noninvasive ventilation). 6) Reassess frequently: After each nebulizer, reassess respiratory rate, SpO2, breath sounds, and work of breathing. Document response. 7) Provide comfort and education: Keep child calm; educate mother on asthma action plan and proper inhaler technique.
2. The child's mother asks why her daughter is receiving both albuterol and ipratropium, and why steroids are necessary. How would you explain this in lay terms, and what key teaching points would you include before discharge?

Explanation: "Albuterol is a quick-relief medicine that opens the airways by relaxing the muscles around them. Ipratropium is another bronchodilator that works in a different way to help keep the airways open longer. Using them together gives faster and stronger relief during a flare-up. The steroid (prednisolone) is not a quick-relief medicine; it works over several hours to reduce the swelling and inflammation inside the airways, which is causing the wheezing and tightness. Without the steroid, the inflammation would continue and the albuterol might not work as well."
Key teaching points before discharge: 1) Asthma action plan: Provide a written plan with green/yellow/red zones, specifying when to use reliever, when to call the doctor, and when to go to the ED. 2) Inhaler technique: Demonstrate and have the mother and child practice using a spacer with the albuterol inhaler. 3) Medication schedule: Prednisolone should be given as prescribed (e.g., once daily for 3-5 days) and finished completely; do not stop abruptly. 4) Trigger avoidance: Discuss viral infections as triggers, hand hygiene, and avoiding sick contacts. 5) Monitoring: Teach signs of worsening asthma (increased wheeze, retractions, difficulty speaking, pale or bluish lips) and when to seek emergency care. 6) Follow-up: Ensure follow-up with primary care or asthma specialist within 1-2 weeks. 7) Vaccination: Ensure influenza vaccine is up to date. 8) School plan: Provide school with medication and action plan.
