Which of the following is a major sign of anaphylaxis?

• A. Difficulty breathing
• B. Chronic cough
• C. Abdominal pain
• D. Headache

Answer: (A)

Difficulty breathing is a major sign of anaphylaxis because anaphylaxis is a severe, potentially life-threatening allergic reaction that can occur rapidly after exposure to an allergen. During anaphylaxis, the body releases a flood of chemicals, including histamine, resulting in swelling and narrowing of the airways. This leads to difficulty breathing, which can manifest as wheezing, shortness of breath, or a feeling of tightness in the chest. Recognizing difficulty breathing as a critical sign is essential for prompt treatment, which often involves the administration of epinephrine to reverse these life-threatening symptoms. The other options, while they can occur in various medical conditions, are not definitive signs of anaphylaxis. Chronic cough might indicate respiratory issues or infections, abdominal pain may arise from various gastrointestinal problems, and headaches can be associated with numerous causes unrelated to allergic reactions. These symptoms do not present the same immediate danger to life as difficulty breathing does in the context of anaphylaxis.
