What is a sign of anaphylaxis?

• A. Elevated blood pressure
• B. Wheezing
• C. Absence of swelling
• D. Constricted pupils

Answer: (B)

Wheezing is a key sign of anaphylaxis, which is a severe and potentially life-threatening allergic reaction. During anaphylaxis, the body releases a flood of chemicals, leading to symptoms such as airway inflammation and bronchoconstriction. This results in difficulty breathing, which is often characterized by wheezing—a high-pitched whistling sound produced during exhalation. Recognizing wheezing as a symptom is critical for timely intervention, as it indicates that the airway may be compromised and immediate treatment, such as administering epinephrine, is necessary. Other symptoms commonly associated with anaphylaxis include hives, swelling, difficulty swallowing, and gastrointestinal distress. Being aware of these signs helps responders act quickly to mitigate the effects of the reaction and prevent further complications.
