A nurse is assessing patient response to medications received. Which must the nurse know about these drugs to best evaluate whether the expected outcomes of the drug therapy have been achieved?
Therapeutic effects
Chemical composition
Mechanism of actions
Side effects
The Correct Answer is A
Choice A reason: Therapeutic effects define expected outcomes; knowing these (e.g., pain relief) lets the nurse assess if the drug meets its clinical goal effectively.
Choice B reason: Chemical composition informs structure, not outcome; it’s irrelevant to evaluating if the drug achieves its intended physiological effect directly.
Choice C reason: Mechanism explains how drugs work; it’s useful but secondary to knowing the actual therapeutic result needed for outcome assessment.
Choice D reason: Side effects monitor safety, not efficacy; they don’t directly measure if the drug achieves its primary therapeutic purpose as intended.

Correct Answer is D
Explanation
Choice A reason: PRN is as needed; EKGs here are routine, not symptom-driven, making this inapplicable to a standard admission protocol for all patients.
Choice B reason: One-time is a single event; this order applies to all admissions ongoing, not a one-off, distinguishing it from limited-duration directives.
Choice C reason: STAT is immediate; routine EKGs aren’t urgent, occurring as part of standard care, not requiring the priority of acute intervention orders.
Choice D reason: Standing orders apply automatically to all qualifying patients; this EKG protocol fits, ensuring consistent cardiac assessment unless overridden.
Correct Answer is C
Explanation
Choice A reason: Four times (6:00 a.m., noon, 6:00 p.m., midnight) is QID, not TID; TID means three times daily, and this schedule overdoses the patient unnecessarily.
Choice B reason: Six times daily is every 4 hours, not TID; this exceeds the three-dose requirement, risking toxicity or side effects from excessive administration frequency.
Choice C reason: 9:00 a.m., 1:00 p.m., 5:00 p.m. is TID; spaced 8 hours apart, it aligns with standard three-times-daily dosing, ensuring consistent therapeutic levels safely.
Choice D reason: Meal and bedtime timing is vague; without fixed hours, it risks uneven dosing intervals, potentially disrupting pharmacokinetics and efficacy of the medication.
