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 D
Explanation
Choice A reason: Bolus is instant; time-release spreads meds slowly instead. Reduced doses fit better. This errors per nursing pharmacology. It’s universally distinct, incorrect.
Choice B reason: Crushing ruins time-release; reduced dosing is the goal. This choice misaligns with nursing standards. It’s universally distinct, errors in handling.
Choice C reason: Pills aren’t specific to time-release; dose reduction is key. This errors per nursing pharmacology. It’s universally distinct, lacks precision.
Choice D reason: Time-release capsules extend action, cutting daily doses effectively. This aligns with nursing pharmacology standards. It’s universally distinct, reducing frequency.
Correct Answer is C
Explanation
Choice A reason: Antihistamines block histamine, not raise HR or BP. Epinephrine fits emergency needs. This errors per nursing pharmacology. It’s universally distinct, lacking stimulatory emergency effects.
Choice B reason: Sedatives reduce activity, not increase HR or BP. Epinephrine acts oppositely. This choice reverses nursing standards. It’s universally distinct, unsuitable for emergency stimulation.
Choice C reason: Epinephrine boosts HR, BP, and dilates bronchi in emergencies. This matches nursing pharmacology standards. It’s universally applied, distinctly effective for acute life-saving interventions.
Choice D reason: Hormones vary; epinephrine specifically meets all criteria emergently. This lacks precision per nursing standards. It’s universally distinct, too vague for the question’s intent.
