A patient is due for a 40-mg dose of furosemide (Lasix) at 9:00 AM on May 5, 2013. The drug label reads "20 mg per tablet." The tablets in the bottle appear firm and unbroken. The expiration date on the bottle reads "April 2, 2013." The best nursing action is to:
Administer one-half tablet.
Administer two tablets.
Call the pharmacy to see if 40-mg tablets are available.
Call the pharmacy for a new bottle of the medication.
The Correct Answer is D
Choice A reason: Half a tablet (10 mg) underdoses; expired drugs may degrade, and 40 mg is needed for diuresis, risking therapeutic failure in this scenario.
Choice B reason: Two tablets (40 mg) meet the dose but are expired; potency loss post-April 2013 risks inefficacy or toxicity, compromising patient safety.
Choice C reason: Seeking 40-mg tablets ignores expiration; even if available, current stock is outdated, and fresh supply is still required for reliable effect.
Choice D reason: Expired drugs (April 2013) lose potency; a new bottle ensures 40 mg of active furosemide, maintaining efficacy and safety for hypertension or edema.

Correct Answer is B
Explanation
Choice A reason: 60 gtts/min assumes 100 mL in 100 minutes; this underestimates the 1-hour order, delivering Levaquin too slowly, risking subtherapeutic antibiotic levels.
Choice B reason: 100 gtts/min is correct; 100 mL over 1 hour (60 min) with 60 gtts/mL equals 6000 gtts total, divided by 60 minutes matches the ordered rate.
Choice C reason: 120 gtts/min overestimates; it implies 100 mL in 50 minutes, infusing too fast, potentially causing Levaquin-related side effects like tachycardia or irritation.
Choice D reason: 200 gtts/min is excessive; 100 mL in 30 minutes doubles the rate, risking toxicity or infusion reactions, far exceeding the 1-hour prescription safely.
Correct Answer is B
Explanation
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.
