All the following are true about Lasix (furosemide) except:
It increases water loss by the excretion of sodium
It may cause the patient to become hypokalemic
It is a potassium-sparing diuretic
The nurse should tell the patient to change positions slowly
The Correct Answer is C
Choice A reason: Lasix increases sodium and water excretion, a true diuretic effect. Potassium-sparing is false, per nursing pharmacology. This holds universally, distinctly accurate.
Choice B reason: Lasix depletes potassium, causing hypokalemia; this is true. Potassium-sparing isn’t, per nursing standards. It’s universally recognized, distinctly a known risk.
Choice C reason: Lasix isn’t potassium-sparing; it’s a loop diuretic that loses potassium. This is the exception, per nursing pharmacology. It’s universally distinct, errors in classification.
Choice D reason: Slow position changes prevent Lasix-induced hypotension; this is true. Potassium-sparing is wrong, per nursing standards. It’s universally distinct, a safety measure.

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 C
Explanation
Choice A reason: Sedatives induce calm, not lower blood pressure directly. Vasodilators target BP reduction specifically. This choice errors per nursing pharmacology standards. It’s universally distinct as unrelated to BP management, lacking the required mechanism.
Choice B reason: Intermediate-acting defines duration, not BP-lowering action. Vasodilators reduce pressure effectively. This choice misaligns with nursing pharmacology definitions. It’s universally distinct, missing the functional role specified in the question.
Choice C reason: Vasodilators, like nitroglycerin, widen vessels, lowering BP efficiently. This matches nursing pharmacology standards precisely. It’s universally recognized, distinctly applied in practice for hypertension or angina management effectively.
Choice D reason: Vasoconstrictors raise BP, opposite of lowering it. Vasodilators fit the description accurately. This choice errors per nursing pharmacology principles. It’s universally distinct, contradicting the question’s intent entirely.
