Stage 2 — Analyze cues. For each reassessment finding, identify the conclusion it supports. More than one column may apply to a finding.

Quick answer
Separate evidence of obstruction from evidence that the child is tiring; drowsiness plus minimal air movement supports both.

Why this is correct
Low oxygen saturation, a peak flow near one-third of personal best, and interrupted speech reflect severe obstruction. Declining alertness and minimal air movement raise the additional concern that respiratory muscles are failing.

Easy analogy or mental picture
Use two warning gauges: one shows how narrow the airway is, and the other shows whether the child can keep breathing against that resistance. A fast pulse after albuterol is a medication-effect clue, not either gauge by itself.

Memory hook
Obstruction is tight; failure is tired.

NCLEX decision rule
When asthma findings stay severe after initial treatment, check both airflow and mental status; reduced breath sounds with drowsiness demands escalation.

Why the other choices are wrong
A beta-agonist-related pulse increase is expected in context and cannot independently establish treatment failure or ventilatory collapse.
