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

Answer and Explanation

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 A

Explanation

Choice A reason: Withholding and rechecking ensures safety; a color change signals a potential error, and verifying the MAR against orders prevents administering the wrong drug.

Choice B reason: Assuming a change is risky; without confirmation, administering an unverified drug could harm the patient if it’s not the intended prescription.

Choice C reason: Administering then checking later endangers the patient; a wrong drug could cause adverse effects, and delayed verification violates safety protocols.

Choice D reason: Describing and giving without verification is unsafe; the red tablet may not match the order, risking incorrect treatment or allergic reactions.

A. 610 mL B. 710 mL C. 810 mL D. 910 mL

Correct Answer is B

Explanation

Choice A reason: 610 mL omits ice cream (120 mL); total is 120 + 120 + 260 + 90 + 120 = 710 mL; this undercalculation misses a key liquid intake component.

Choice B reason: 710 mL sums all: 120 (juice) + 120 (milk) + 260 (coffee) + 90 (ice pop) + 120 (ice cream); melted solids count as fluid, matching clinical standards.

Choice C reason: 810 mL overestimates; no additional fluids are listed beyond 710 mL; this error likely adds non-existent intake, skewing the total inaccurately.

Choice D reason: 910 mL vastly exceeds reality; it may double-count or invent fluids; only 710 mL is supported by the listed consumption data provided.
