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?

Choice A rationaleNitrates are vasodilators used primarily to treat angina and heart conditions. They are not related to the administration of acetazolamide, which is a diuretic medication.Choice B rationaleSulfa-based medications are contraindicated in patients with sulfa allergies. Acetazolamide contains a sulfonamide group, which can trigger allergic reactions in susceptible individuals.Choice C rationaleAntilipemic agents are used to lower lipid levels in the blood and are unrelated to acetazolamide, which is used to decrease intraocular pressure in glaucoma patients.Choice D rationaleProton pump inhibitors are used to reduce stomach acid production and have no known interaction with acetazolamide. They are prescribed for conditions like GERD and peptic ulcer disease.
