Which of the following is a common symptom of anaphylaxis?

Shortness of breath and wheezing are indeed common symptoms of anaphylaxis, a severe, potentially life-threatening allergic reaction. During anaphylaxis, the body releases a flood of chemicals in response to the allergen, which can lead to narrowing of the airways, resulting in difficulty breathing and wheezing. This respiratory distress is critical to recognize, as it signifies that the individual may need immediate medical intervention, such as the administration of epinephrine.

The other symptoms listed, while they can indicate various medical conditions, are not typical of anaphylaxis. Rash and skin lesions may occur in allergic reactions but are not as critical as respiratory symptoms. Severe headache and confusion can be associated with other medical issues like migraines or neurological conditions. Fever and chills are typically related to infections rather than anaphylaxis. Understanding these distinctions is essential for timely and appropriate responses to allergic reactions.
