In the described peanut-allergic case, which sign indicates airway involvement requiring urgent treatment?

• A. Headache
• B. Whistling sounds while breathing
• C. Abdominal pain
• D. Skin rash

Answer: (B)

Airway involvement in a peanut allergy shows up as wheezing—whistling sounds during breathing—because the airways are narrowing from bronchospasm and potential swelling. That signs that the airway could be compromised, so it requires urgent treatment to prevent obstruction. While headache, abdominal pain, or a skin rash can occur with allergic reactions, they don’t specifically indicate the airway is involved. Recognizing wheeze as a signal of respiratory involvement is what prompts immediate action, such as administering epinephrine and seeking emergency care.
