Which symptom is often accompanying an anaphylactic reaction?

• A. Fever
• B. Wheezing
• C. Bradycardia
• D. Chest pain

Answer: (B)

Wheezing is a common symptom associated with an anaphylactic reaction. Anaphylaxis leads to severe allergic responses that can cause the airways to constrict due to bronchoconstriction and swelling in the respiratory passages. This constriction results in wheezing, which is a high-pitched whistling sound that occurs during breathing, particularly when exhaling.

During anaphylaxis, the release of chemicals such as histamine causes not only airway swelling but can also lead to increased mucus production and bronchial spasms, further contributing to the wheezing sound. This symptom is particularly notable because it indicates airway compromise, which is a critical issue requiring prompt intervention.

In anaphylactic shock, other symptoms can also be present, such as skin reactions or gastrointestinal distress, but wheezing is significant as it directly points to respiratory involvement, which can pose an immediate threat to breathing and requires urgent medical attention.
