Which of the following is a sign of anaphylactic shock?

  1. Nausea

  2. Headache

  3. Respiratory distress

  4. Itching

The correct answer is: Respiratory distress

Anaphylactic shock is a severe and potentially life-threatening allergic reaction that occurs due to a hyperactive response of the immune system. It is characterized by a sudden drop in blood pressure and difficulty breathing. Nausea and headache are common symptoms of many allergies, but they are not specific to anaphylactic shock. Itching, also known as pruritus, is a common sign of an allergic reaction, but it can occur in varying degrees for different types of allergies and is not a definitive indicator of anaphylactic shock. Respiratory distress, on the other hand, is a hallmark sign of anaphylactic shock and should be taken seriously as an emergency situation requiring immediate medical attention.
