Adolescent with Asthma Exacerbation and Nonadherence
A 14-year-old with moderate persistent asthma is admitted with a 3-day history of cough and wheeze after running out of her controller inhaler 6 weeks ago. She uses her rescue inhaler 'when I remember' and reports waking at night twice a week. On admission: respiratory rate 28/min, SpO2 92% on room air, peak flow 55% of personal best, and audible wheeze with accessory muscle use. She is started on continuous albuterol, ipratropium, and systemic corticosteroids. She tells the nurse, 'My friends think the inhaler is embarrassing, and my mom is always nagging me about it. I just want to go home.'
1. Assess the severity of this exacerbation and outline the monitoring and medication priorities for the first 24 hours.

Severity: This is a moderate-to-severe exacerbation. Peak flow at 55% of personal best falls in the moderate range (40-69%), but the presence of accessory muscle use, tachypnea at 28/min, SpO2 of 92%, and nocturnal symptoms twice weekly indicate poor control and a significant acute episode. SpO2 below 90-92% on room air is a warning sign for hypoxemia.
Monitoring priorities:
- Continuous pulse oximetry with a target SpO2 of at least 90-92%; titrate oxygen.
- Peak flow before and after bronchodilator treatments to track response.
- Respiratory rate, work of breathing, and ability to speak in full sentences; reassess frequently.
- Watch for impending respiratory failure: silent chest, decreasing wheeze with worsening distress, drowsiness, or rising CO2.
Medication priorities:
- Short-acting beta agonist (albuterol) by nebulizer or metered-dose inhaler with spacer; continuous or frequent dosing initially, then wean based on response.
- Ipratropium added during the acute phase reduces hospitalization when combined with albuterol.
- Systemic corticosteroids (e.g., oral prednisolone or IV methylprednisolone) early - they reduce inflammation and relapse; expect benefit over hours, not minutes.
- Oxygen to maintain saturation.
- Consider magnesium sulfate IV for severe exacerbations not responding to initial therapy.
- Do not start antibiotics unless there is evidence of bacterial infection; most exacerbations are viral.
Document response to each treatment and escalate if peak flow does not improve or the child tires.
2. How would you address the adherence and psychosocial issues before discharge, and what discharge teaching would reduce readmission risk?

Adherence in adolescents is driven by identity, autonomy, and routine, not by warnings. Nagging from a parent and embarrassment with peers are powerful barriers. Use a motivational, nonjudgmental approach:
- Ask open questions: 'What gets in the way of using the controller?' and 'What would make it easier to remember?'
- Explore the peer issue directly: discuss discreet carrying options, timing doses at home rather than at school, and framing the inhaler as something that keeps her on the team or in activities she values.
- Involve the adolescent in the plan and give her a written asthma action plan with zones based on peak flow and symptoms.
- Address the parent separately: coach toward support rather than surveillance, and agree on who is responsible for refills.
- Screen for mood and anxiety, which are common in adolescents with chronic illness and worsen control.
Discharge teaching:
- Technique check: demonstrate and have her teach back inhaler and spacer use; a spacer improves delivery.
- Controller vs. rescue distinction: daily controller even when well; rescue for symptoms; know when to call.
- Refill and access plan: identify a pharmacy, set a phone reminder, and confirm insurance coverage.
- Trigger avoidance: assess home triggers (pets, mold, smoke) and refer for environmental assessment if indicated.
- Follow-up within 3-7 days with primary care or asthma clinic, plus a written plan for school.
- Teach-back on action plan zones and when to seek emergency care.
Arrange a follow-up call or visit to check refill and technique, since the root cause was running out of medication.
