In a patient stung by Hymenoptera, which sign indicates possible airway compromise?

• A. Itching at sting site
• B. Airway swelling
• C. Local swelling only
• D. Nausea

Answer: (B)

Airway compromise from a Hymenoptera sting shows itself when the tissues of the airway—the tongue, lips, throat, or pharynx—start to swell. This edema can quickly narrow or block the airway, making it hard to breathe, speak, or swallow. That direct sign of swelling in the airway is the clearest warning that obstruction could occur, which is why it’s the best indicator in this scenario. Other symptoms, like itching at the sting site or local swelling, are reactions limited to the sting area and don’t by themselves signal a dangerous airway blockage. Nausea may occur with a systemic allergic reaction, but it doesn’t tell you whether the airway is at risk. If airway swelling is present, treat the situation as an emergency: support breathing, monitor closely, and seek urgent care, giving epinephrine if it’s available and you’re trained to administer it.
