A client is to receive a medication at 9:00 A.M. To prevent a medication error by administering at the incorrect time, the nurse can administer the medication anytime between:

8:00 and 10:00 A.M.

8:30 and 9:30 A.M.

8:30 and 9:00 A.M.

8:45 and 9:15 A.M.

Answer and Explanation

The Correct Answer is D

Choice A reason: Two-hour window (8:00-10:00) is too broad; most protocols allow 30 minutes before/after, as wider ranges risk altering drug pharmacokinetics significantly.

Choice B reason: One-hour window (8:30-9:30) is common but exceeds some strict policies; it’s less precise, potentially affecting drugs with tight timing needs.

Choice C reason: 8:30-9:00 is only before; it excludes post-9:00 flexibility, limiting administration to early dosing, which may not align with full protocol windows.

Choice D reason: 8:45-9:15 (30 minutes either side) fits standard policy; it ensures therapeutic levels for most drugs, balancing efficacy with practical scheduling.

Correct Answer is D

Explanation

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Choice C reason: Seeking 40-mg tablets ignores expiration; even if available, current stock is outdated, and fresh supply is still required for reliable effect.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.

A. The patient is unable to exercise due to severe osteoarthritis in both hips. B. The patient follows a low-carbohydrate, low-protein, high-fat diet. C. The patient has a history of hypertension and diabetic kidney disease. D. The patient has a 35 pack-year history of cigarette smoking.

Correct Answer is C

Explanation

Choice A reason: Osteoarthritis limits mobility; it doesn’t affect kidney function directly, so nephrotoxic drug clearance remains unchanged, not warranting a dose reduction.

Choice B reason: Diet impacts metabolism slightly; low protein may spare kidneys, but it doesn’t indicate impaired clearance requiring adjustment of nephrotoxic medication.

Choice C reason: Diabetic kidney disease with hypertension impairs filtration; reduced glomerular rate necessitates lower nephrotoxic doses to prevent further renal damage.

Choice D reason: Smoking affects lungs primarily; while it may indirectly harm kidneys, it’s less definitive than diabetic nephropathy for needing a reduced dose.
