When administering a medication, a nurse should check the label on the drug container against the MAR when removing the drug container from the client's medication drawer, when removing the drug from the medication container, and:
After showing the drug label to the client
Before returning the drug container to the client’s medication drawer
Before calling the pharmacy
After checking the drug container with a colleague
The Correct Answer is B
Choice A reason: Showing the client isn’t a standard check; patients don’t verify MAR, and this step lacks relevance to the nurse’s triple-check safety protocol.
Choice B reason: Checking before returning ensures accuracy; the third check confirms the right drug post-administration, completing the three-point verification process safely.
Choice C reason: Calling the pharmacy is unrelated; label checks occur during administration, not external consultation, making this an irrelevant timing option.
Choice D reason: Colleague checks aren’t routine; the three checks are individual, and this step doesn’t align with standard MAR verification timing protocols.

Correct Answer is B
Explanation
Choice A reason: Separate syringes increase injection sites and patient discomfort; mixing is standard as Regular and NPH are compatible, optimizing insulin delivery efficiency and absorption.
Choice B reason: Drawing Regular (clear) before NPH (cloudy) in one syringe prevents contamination of the short-acting vial with the intermediate-acting insulin, ensuring accurate dosing and stability.
Choice C reason: Shaking insulin damages its structure; NPH requires gentle rolling to mix, while Regular needs no mixing, making vigorous shaking inappropriate for preparation.
Choice D reason: Drawing NPH first risks contaminating the Regular vial with NPH particles, altering its rapid action; the clear-to-cloudy sequence maintains insulin integrity and efficacy.
Correct Answer is A
Explanation
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.
