What is a sign of mild allergic reactions?

• A. Shock
• B. Hives
• C. Respiratory failure
• D. Anaphylaxis

Answer: (B)

Hives, or urticaria, are indeed a sign of mild allergic reactions. They are raised, itchy welts on the skin that can vary in size and appear anywhere on the body. The occurrence of hives demonstrates the body's immune response to an allergen, which can be due to a variety of triggers such as foods, medications, or insect stings. In contrast, shock, respiratory failure, and anaphylaxis are indicators of more severe allergic reactions or systemic responses. Shock refers to a critical condition where there is inadequate blood flow to the organs, respiratory failure indicates a serious compromise in breathing, and anaphylaxis is a life-threatening reaction that involves multiple body systems and can include symptoms like difficulty breathing, rapid swelling, and a drop in blood pressure. Mild allergic reactions typically manifest as localized skin reactions, such as hives, and do not escalate to these more serious conditions.
