Which of the following is a symptom of severe anaphylaxis?

• A. Sneezing
• B. Itching
• C. Swelling of face/neck/tongue
• D. Rash on hands

Answer: (C)

Severe anaphylaxis involves rapid airway compromise and systemic involvement. Swelling of the face, neck, and tongue signals that the upper airway is starting to close, which can quickly block breathing and require urgent treatment. That’s why this symptom best indicates a dangerous, progressing reaction. Sneezing and itching can occur with allergic reactions but don’t by themselves show dangerous airway swelling. A rash on the hands is not a hallmark sign of a severe, life-threatening reaction and may reflect a milder or localized response. In flight, recognizing facial/neck/tongue swelling helps trigger immediate actions such as administering epinephrine if available, summoning medical help, and preparing for potential emergency descent.
