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 B
Explanation
Choice A reason: Changes signal potential instability, not normal variation; returning is safer. This errors, per nursing pharmacology. It’s universally distinct, risking potency loss in administration.
Choice B reason: Altered color, consistency, or odor suggests degradation; returning ensures safety. This aligns with nursing standards. It’s universally applied, distinctly protecting patients from ineffective drugs.
Choice C reason: Nurses assess drugs, not just pharmacists; returning is nurse-initiated. This misplaces responsibility, per nursing pharmacology. It’s universally distinct, errors in duty allocation.
Choice D reason: Giving altered drugs risks harm; reporting alone isn’t enough. Returning is safer, per nursing standards. This fails universally, distinctly compromising medication safety.
Correct Answer is B
Explanation
Choice A reason: Smoking impacts liver, not kidney excretion speed primarily. Liver metabolism accelerates instead. This choice errors per nursing pharmacology. It’s universally distinct, targeting the wrong organ for effect.
Choice B reason: Smoking induces liver enzymes, speeding drug metabolism significantly. This aligns with nursing pharmacology standards. It’s universally recognized, distinctly affecting drug efficacy and dosing needs.
Choice C reason: Smoking hastens, not slows, liver drug metabolism typically. This choice reverses nursing pharmacology facts. It’s universally distinct, contradicting known metabolic effects of smoking.
Choice D reason: Kidney excretion isn’t slowed by smoking; liver speeds metabolism. This choice misaligns with nursing standards. It’s universally distinct, errors in organ and effect direction.
