Which of the following is NOT a sign of anaphylaxis?

Anaphylaxis is a severe, potentially life-threatening allergic reaction characterized by a specific set of symptoms that occur rapidly after exposure to an allergen. The other choices listed are classic signs of anaphylaxis.

Shortness of breath is a common respiratory symptom resulting from airway constriction and is often accompanied by wheezing, which is a high-pitched whistling sound made while breathing. An elevated heart rate (HR 140) can occur in response to the shock and stress of a severe allergic reaction, as the body attempts to compensate for decreased blood flow and oxygenation.

On the other hand, a temperature of 101.5°F is not typically associated with anaphylaxis. While fever can indicate infection or inflammatory processes, it is not a direct symptom of anaphylaxis. The hallmark signs of anaphylaxis primarily involve respiratory distress, cardiovascular symptoms, and gastrointestinal distress, rather than an elevated body temperature. Hence, a fever of 101.5°F would not be seen as a sign of anaphylaxis.
