Which symptom best signals an allergic reaction requiring urgent care?

• A. Mild nasal congestion
• B. Rash, swelling, difficulty breathing
• C. Slight headache
• D. Dry mouth

Answer: (B)

The major sign is a combination of a rash with swelling and trouble breathing, because that pattern points to a severe allergic reaction that can progress rapidly and endanger the airway. In a sea kayak scenario, exposure to stings, foods, medications, or environmental triggers can trigger this kind of reaction, so recognizing the warning is crucial. When this happens, it’s an urgent situation: call emergency services and, if you’re trained and have access to an epinephrine auto-injector, use it while stabilizing the person and getting help.

Mild nasal congestion, a slight headache, or dry mouth can occur for a variety of non-emergency reasons and don’t by themselves indicate a life-threatening allergic reaction.
