Which symptom is the most common with a hypersensitivity reaction to a medication?
Correct answer
A
Rationale
The correct answer is A: Urticaria. This is the most common symptom in a hypersensitivity reaction to medication due to the release of histamine, causing skin rash and itching. Vomiting (B) and wheezing (C) can occur but are less common. Anaphylaxis (D) is a severe, life-threatening reaction that can include urticaria but is not the most common symptom.
