Clinical assessment of pediatric asthma prioritizes stabilizing acute respiratory distress before pursuing differential diagnosis, since asthma is by far the most common cause of wheeze in children. The physical exam integrates respiratory findings (air entry, character and timing of wheeze, presence of rhonchi or crackles as alternative-diagnosis clues), cardiac findings (accounting for drug-induced tachycardia), and signs of chronic hyperinflation (a palpable liver edge from diaphragmatic displacement) alongside allergic stigmata, while findings such as clubbing or failure to thrive signal that a diagnosis other than asthma should be pursued. This concept belongs to pediatric pulmonology and demonstrates a diagnostic reasoning principle: acute management precedes diagnostic certainty when a common, life-threatening condition is highly likely.
