Which of the following is a key sign of a severe anaphylactic reaction?

• A. Swelling of face/neck/tongue
• B. Nausea only
• C. Sneezing
• D. Cough

Answer: (A)

Airway involvement signals a severe anaphylactic reaction. Swelling of the face, neck, or tongue shows edema around the airway, which can rapidly narrow or block breathing. This makes it a critical red flag because the situation can deteriorate quickly without prompt treatment. Nausea alone, sneezing, or a cough can accompany milder allergies or other conditions and do not indicate immediate airway danger. Recognizing the facial/neck/tongue swelling prompts urgent action, including administering epinephrine if available and calling for emergency help.
