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: 31 gtts/min assumes 250 mL over 4 hours with 15 gtts/mL; this halves the rate, underdelivering vancomycin, risking subtherapeutic levels and ineffective bacterial killing over the prescribed 2-hour infusion time.
Choice B reason: 62 gtts/min is correct; 250 mL over 2 hours is 125 mL/hr, times 15 gtts/mL equals 1875 gtts total, divided by 120 minutes yields 62 gtts/min, ensuring proper antibiotic delivery.
Choice C reason: 125 gtts/min doubles the rate; 250 mL in 1 hour with 15 gtts/mL is too fast, risking vancomycin toxicity, including renal damage, and exceeding safe infusion guidelines for IVPB.
Choice D reason: 250 gtts/min assumes 250 mL in 30 minutes; this dangerously rapid rate could cause vancomycin-induced red man syndrome or cardiovascular overload, far beyond the ordered 2-hour infusion duration.
Correct Answer is B
Explanation
Choice A reason: Lisinopril is the generic name; trade names are branded, and this doesn’t fit the question’s focus on the manufacturer’s marketed title.
Choice B reason: Zestril is the trade name for lisinopril; it’s trademarked by the manufacturer, aligning with the question’s request for the branded medication name.
Choice C reason: Acetaminophen is a generic, not a trade name here; it’s unrelated to Zestril’s class (ACE inhibitor), making it an incorrect option.
Choice D reason: Morphine is a generic opioid; it doesn’t match Zestril’s antihypertensive role or trade name status, ruling it out entirely.
