Case Study — Pediatrics
Pediatric Asthma NGN Case Study
A Next Gen NCLEX-style unfolding case. Read each step, commit to your own answer — out loud or on paper — and only then reveal ours. The six steps mirror the NCSBN Clinical Judgment Measurement Model exactly as the exam tests it.

Educational use only. This case is a learning exercise with simplified values, not a treatment protocol — real pediatric asthma care follows provider orders, weight-based dosing, and your facility’s severity pathway. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
The Scenario
1920, pediatric ED: Mateo, 6, known asthmatic, arrives with his mother after two days of a runny nose and cough. Tonight his breathing “got loud and fast” and his home inhaler “wasn’t working anymore — we used it three times in two hours.” He had one ED visit last year for asthma; he is on an as-needed albuterol inhaler only.
1925 Assessment
- HR 138 · RR 40 · SpO₂ 89% RA · Temp 37.4°C · Weight 21 kg
- Sitting upright on mom’s lap, leaning forward; speaks in 2–3 word bursts
- Audible expiratory wheeze; subcostal and intercostal retractions; nasal flaring
- Anxious, clinging to mother; skin pale, no cyanosis
- Diffuse expiratory wheezes throughout both lungs on auscultation
Step 1 — Recognize Cues
Which findings are most relevant — and which matter most right now? Remember his age when judging the vitals.
▸Reveal answer
Most concerning cues: SpO₂ 89%, retractions in two muscle groups plus nasal flaring (the work-of-breathing trio), RR 40 and HR 138 — both high even for a six-year-old — broken speech, and tripod-on-mom positioning. The history cue that grades severity: three albuterol doses in two hours with no relief — rescue-refractory bronchospasm.
Context cues: the URI trigger (the most common one in children), and a regimen of rescue-inhaler-only with prior ED visits — a controller-medication gap worth flagging for later.
Reassuring-for-now cues: he is alert, anxious (anxiety means he’s perfusing his brain and fighting), and wheezing audibly — a child loud enough to wheeze is still moving air. File that sentence; it matters later.
Step 2 — Analyze Cues
What conditions could explain this picture? Connect the cues to at least three possibilities and decide which the evidence supports.
▸Reveal answer
Severe asthma exacerbation (most supported): known asthma + URI trigger + diffuse bilateral expiratory wheeze + rescue-refractory symptoms. The pattern is textbook; the severity markers (hypoxemia, retractions, broken speech) grade it severe.
Foreign-body aspiration: the great pediatric mimic — but it favors sudden onset without a URI story and unilateral findings. His bilateral wheeze and two-day prodrome argue against it.
Croup: wrong sound and wrong phase — croup is inspiratory stridor with a barking cough, upper airway; this is expiratory wheeze, lower airway.
Pneumonia: possible companion (low-grade temp); focal crackles or persistent hypoxemia after bronchodilation would raise it. It would be treated alongside, not instead.
Step 3 — Prioritize Hypotheses
Rank your hypotheses — and name the deterioration you are specifically watching for.
▸Reveal answer
1. Severe asthma exacerbation heading toward respiratory failure — children compensate brilliantly and then fall off a cliff. The feared trajectory is status asthmaticus → silent chest → fatigue → respiratory arrest. The watch-fors: wheeze going quiet, slowing respiratory rate, drowsiness, and a child who stops fighting — each looks like “calming down” and means the opposite.
2. Coexisting pneumonia — sorted by exam and response to treatment.
NGN logic: in pediatric respiratory cases, the priority isn’t just the diagnosis — it’s the trajectory. Your reassessments are the alarm system, and knowing what deterioration looks like beats reacting to it late.
Step 4 — Generate Solutions
What should the first hour look like? Draft your action list — include how you’ll handle the child himself.
▸Reveal answer
Anticipated orders: oxygen to keep SpO₂ ≥90–92%; continuous or back-to-back nebulized albuterol with ipratropium; systemic corticosteroids early (oral or IV — they take hours to work, which is why they can’t wait); reassessment after each treatment cycle. If refractory: IV access, magnesium sulfate, and a PICU conversation.
Pediatric craft: keep him on mom’s lap, in his position of comfort — separating an air-hungry child or forcing him supine worsens everything. Blow-by or mask per tolerance, calm voice, involve mom in holding the mask. Defer non-urgent IVs and labs until bronchodilators are flowing; crying collapses small airways.
Reassess like it’s your job (it is): air entry, retractions, speech length, mental status, SpO₂, and heart rate after every treatment — expect albuterol to push the HR higher; that’s tolerated, not a reason to stop.
Step 5 — Take Action
2015, after two treatment cycles: a colleague reports, “Good news — he’s much quieter, barely wheezing now, and he’s finally settling down, almost dozing.” SpO₂ reads 90% on the mask. What do you do with that report?
▸Reveal answer
Go assess him now — this report is the silent-chest alarm. “Quieter wheeze + sleepy child” has two readings: genuine improvement, or air movement so poor there’s nothing left to wheeze with, plus CO₂-retention drowsiness. The discriminator is air entry on auscultation: improving children have MORE breath sounds, longer sentences, easing retractions, and brighter affect. He has diminished air entry bilaterally, ongoing retractions, and is hard to rouse.
Escalate immediately: rapid response/provider to bedside, continuous albuterol, prepare IV access for magnesium sulfate and steroids if not yet given, blood gas anticipated (a normalizing CO₂ in a tachypneic asthmatic is failure approaching, not success), and a PICU transfer conversation now — before the arrest, not after.
Keep mom in the loop: a calm, honest sentence — “his breathing is telling us he needs more help, so we’re bringing the team in” — keeps her a partner instead of a bystander.
Step 6 — Evaluate Outcomes
Day 2, pediatric floor: after continuous nebs, IV steroids, and magnesium in the PICU overnight, Mateo is on intermittent treatments, SpO₂ 96%, talking in full sentences, negotiating for popsicles. Discharge planning begins. Which findings show success — and what has to happen before this family goes home?
▸Reveal answer
Improving: full sentences, air entry restored, retractions gone, saturations holding on room air between treatments, and a personality back online — the most reliable pediatric monitor of all.
Before discharge, the family needs: a written asthma action plan (green/yellow/red zones with exact doses and the when-to-call-911 line), a spacer demonstration with teach-back — most children’s “inhaler not working” is technique — the oral steroid course completed as prescribed, trigger review (URIs, smoke exposure, allergens), and the controller-medication conversation: rescue-only management with two ED visits is the pattern that earns a daily inhaled corticosteroid and a follow-up appointment that actually gets made.
The loop closes when mom can say back what yellow zone looks like and what she’ll do — evaluation here means the next exacerbation goes differently.
Debrief — The Pattern to Keep
- ✦A wheezing child is moving air; a quiet, sleepy asthmatic may be about to stop — auscultate air entry before celebrating.
- ✦Severity is graded at the bedside: speech length, retractions, position, mental status — not the wheeze volume.
- ✦Steroids early (they take hours), bronchodilators continuously, child on the parent's lap in the position of comfort.
- ✦A normalizing CO₂ in a struggling asthmatic is a failure sign — the gas should be LOW while they're working hard.
- ✦Discharge is teaching: action plan, spacer technique with teach-back, finish the steroids, and fix the controller gap.
