A nurse is caring for a client who has open-angle glaucoma and a new prescription for acetazolamide. Prior to administering the first dose, the nurse should ask the client if they have an allergy to which of the following medication classifications?
Correct answer
B
Rationale
The correct answer is B: Sulfa-based medications. Acetazolamide belongs to the sulfonamide drug class, which can cause allergic reactions in individuals with sulfa allergies. By asking about sulfa allergies, the nurse can prevent a potentially severe allergic reaction. Nitrates (A), antilipemic agents (C), and proton pump inhibitors (D) are unrelated to acetazolamide and do not pose a cross-reactivity risk.
