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 A
Explanation
Choice A reason: Antiparkinson drugs, like levodopa, restore dopamine and balance acetylcholine, vital for nerve signaling in Parkinson’s disease. This corrects motor deficits, aligning with nursing pharmacology. These neurotransmitters are universally targeted, distinctly addressing the disease’s chemical imbalance for effective impulse transmission.
Choice B reason: Epinephrine isn’t a primary Parkinson’s target; dopamine and acetylcholine are key. This misidentifies neurotransmitters involved in motor control, per nursing standards. Epinephrine relates to stress, not nerve restoration, making it a distinct error universally in pharmacology.
Choice C reason: Calcium supports nerve function but isn’t restored by antiparkinson drugs. Acetylcholine and dopamine are specific targets, per nursing knowledge. This choice errors by including calcium, missing the disease’s focus, a universal misunderstanding in pharmacology application distinctly.
Choice D reason: Epinephrine doesn’t treat Parkinson’s; dopamine and acetylcholine do. This pairing misaligns with antiparkinson goals, per nursing pharmacology. It overlooks dopamine’s role in motor control, a distinct error universally recognized in managing nerve impulse transmission effectively.
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.
