What are the signs of anaphylactic shock?

• A. Fever, rash, and muscle pain
• B. Dizziness, vomiting, and abdominal pain
• C. Difficulty breathing, swelling, and hives
• D. Rapid heartbeat, confusion, and numbness

Answer: (C)

The signs of anaphylactic shock are characterized by a rapid and severe allergic reaction that impacts multiple body systems. Difficulty breathing occurs due to airway constriction and swelling, as the body's immune response leads to inflammation in the respiratory pathways. Swelling, particularly of the face, throat, and tongue, can obstruct breathing, which is a life-threatening condition. Hives are another common symptom, resulting from dilated blood vessels and increased permeability, leading to localized swelling and itchy welts on the skin.

This combination of difficulty breathing, swelling, and hives is critical because they indicate a serious systemic reaction that requires immediate medical intervention. Recognizing these signs is essential for prompt treatment, such as administering epinephrine, to reverse the effects of the allergic reaction.
