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 C
Explanation
Choice A reason: While documentation and supervisor notification are crucial, immediate action involving the health care provider ensures timely response to potential adverse effects from the medication error.
Choice B reason: Relying solely on the absence of drug allergies is insufficient and may jeopardize patient safety. Errors require immediate communication and reporting for appropriate interventions.
Choice C reason: Timely provider notification prioritizes patient safety and enables corrective measures. Completing an incident report supports institutional transparency and learning to prevent future errors.
Choice D reason: Administering additional drugs risks compounding harm. The priority is addressing the initial error and ensuring patient safety without introducing further interventions.
Correct Answer is D
Explanation
Choice A reason: Vastus lateralis is muscle; insulin given intramuscularly absorbs too fast, risking hypoglycemia, unlike the slower, safer subcutaneous route intended.
Choice B reason: Deltoid is also muscle; subcutaneous insulin isn’t given here as it’s not fatty enough, leading to unpredictable absorption rates versus abdominal tissue.
Choice C reason: Intravenous line is for IV drugs; insulin via IV is rare and only in emergencies, not standard subcutaneous orders, risking rapid overdose effects.
Choice D reason: Abdominal fat is ideal for subcutaneous insulin; it ensures steady absorption into capillaries, maintaining glycemic control per pharmacokinetic principles.
