Which sign indicates severe distress in an allergic reaction?

• A. Bronchospasm
• B. Severe abdominal pain
• C. Respiratory distress
• D. Stridor

Answer: (D)

Airway compromise from swelling is the most dangerous feature in an allergic reaction. Stridor indicates upper airway narrowing due to laryngeal edema, producing a high-pitched sound that signals impending or ongoing airway obstruction. This finding shows that the airway is at risk, which requires urgent action to secure breathing and treat the reaction. Bronchospasm, while serious, reflects lower airway constriction and often presents with wheezing rather than a clear sign of upper airway obstruction. Respiratory distress is a broad term and can result from various problems, not specifically airway swelling. Abdominal pain isn’t linked to airway involvement in an allergic reaction, so it doesn’t indicate severe distress in this context. So, stridor best signals severe distress from airway involvement in an allergic reaction, guiding the more urgent response.
