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: 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: Lungs aren’t affected by acetaminophen overdose; liver is the target. This misidentifies, per nursing pharmacology. It’s universally distinct, errors in overdose impact.
Choice B reason: Acetaminophen overdose causes liver failure via toxic NAPQI buildup. This matches, per nursing standards. It’s universally recognized, distinctly critical in toxicology.
Choice C reason: Kidneys excrete drugs; liver metabolizes acetaminophen, taking the hit. This errors, per nursing pharmacology. It’s universally distinct, missing the primary organ.
Choice D reason: Adrenals aren’t involved; liver suffers in acetaminophen overdose. This misaligns, per nursing standards. It’s universally distinct, errors in overdose pathology.
