If your patient is on a diuretic, which electrolyte should be watched carefully?
Water
Potassium
Magnesium
Calcium
The Correct Answer is B
Choice A reason: Water isn’t an electrolyte; diuretics primarily deplete potassium levels. This misidentifies the focus, per nursing pharmacology. It’s a universal error, distinctly irrelevant to electrolyte monitoring in diuretic therapy.
Choice B reason: Diuretics like furosemide often cause potassium loss, risking arrhythmias. Monitoring is critical, per nursing standards. It’s universally recognized, distinctly essential for safe management of diuretic effects.
Choice C reason: Magnesium can shift, but potassium is the primary concern with diuretics. This is secondary, per nursing pharmacology. It’s universally distinct, less critical than potassium in routine monitoring.
Choice D reason: Calcium isn’t typically depleted by diuretics; potassium is key. This errors in priority, per nursing standards. It’s universally distinct, missing the main electrolyte risk in diuretic use.

Correct Answer is C
Explanation
Choice A reason: Rectal is enteral, using the GI tract for absorption. Vaginal isn’t enteral. This fits nursing pharmacology standards. It’s universally distinct, part of digestive routes.
Choice B reason: Nasogastric delivers to stomach, an enteral method clearly. Vaginal differs entirely. This aligns with nursing standards. It’s universally distinct, a GI route.
Choice C reason: Vaginal is topical/mucosal, not enteral like GI routes. This is the exception per nursing pharmacology. It’s universally distinct, outside digestive administration methods.
Choice D reason: Oral is enteral, absorbed via digestive system typically. Vaginal isn’t included. This matches nursing standards. It’s universally distinct, a core enteral route.
Correct Answer is D
Explanation
Choice A reason: Amiodarone treats arrhythmias, not vasodilation or BP reduction primarily. Nitroglycerin fits, per nursing pharmacology. This errors universally, distinctly missing cardiac output goals.
Choice B reason: Albuterol dilates airways, not vessels; BP isn’t lowered. Nitroglycerin is correct, per nursing standards. This misaligns universally, distinctly unrelated to vasodilation.
Choice C reason: Pravastatin lowers cholesterol, not BP via vasodilation. Nitroglycerin matches, per nursing pharmacology. This errors universally, distinctly off-target for cardiac effects.
Choice D reason: Nitroglycerin vasodilates, boosts cardiac output, and lowers BP for angina. This aligns, per nursing standards. It’s universally recognized, distinctly effective in practice.
