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.
