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: Antipyretics reduce fever; Coumadin prevents clots, not fever. This misidentifies purpose, per nursing pharmacology. It’s a universal error, distinctly unrelated to anticoagulation therapy.
Choice B reason: Antibiotics fight infection; Coumadin thins blood, not bacteria. This errors in class, per nursing standards. It’s universally distinct, missing Coumadin’s anticoagulant role entirely.
Choice C reason: Coumadin (warfarin) is an oral anticoagulant, preventing clotting effectively. This matches, per nursing pharmacology. It’s universally recognized, distinctly applied for blood clot management.
Choice D reason: Anti-inflammatories reduce swelling; Coumadin targets clotting, not inflammation. This misaligns, per nursing standards. It’s universally distinct, errors in drug classification comprehensively.
Correct Answer is B
Explanation
Choice A reason: 30 cc overestimates; cups lose accuracy below 10 cc typically. Syringes are better for small doses. This errors per nursing standards. It’s universally distinct, impractical for precise small-volume measurement.
Choice B reason: 10 cc is the threshold; below this, cups are inaccurate. Syringes ensure precision, per nursing pharmacology. This aligns universally, distinctly standard for accurate liquid dosing.
Choice C reason: 20 cc exceeds the inaccuracy limit; 10 cc is correct. Cups falter below this level. This choice errors per nursing standards. It’s universally distinct, overestimating the threshold.
Choice D reason: 5 cc underestimates; inaccuracy starts at 10 cc for cups. Syringes are needed below this. This errors per nursing pharmacology. It’s universally distinct, missing the mark.
