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Choice C reason: Seeking 40-mg tablets ignores expiration; even if available, current stock is outdated, and fresh supply is still required for reliable effect.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: One 5-mg tablet delivers 5 mg; this underdoses the 10 mg ordered, reducing salivation stimulation needed for dry eye relief.
Choice B reason: Two 5-mg tablets equal 10 mg; this matches the order, ensuring therapeutic cholinergic effect to increase tear production effectively.
Choice C reason: Three tablets (15 mg) overdose; excess pilocarpine risks side effects (e.g., sweating, bradycardia) without added benefit for dry eyes.
Choice D reason: Four tablets (20 mg) far exceed the dose; this could cause severe cholinergic toxicity, including respiratory distress, outweighing therapeutic intent.
Correct Answer is A
Explanation
Choice A reason: An applicator ensures precise vaginal delivery; it maintains sterility, controls depth, and optimizes medication contact with mucosa for effective absorption.
Choice B reason: Irrigation kits are for flushing; they’re inappropriate for solid or cream medications, risking uneven distribution or mucosal irritation in the canal.
Choice C reason: A finger risks contamination; without sterile technique, it introduces bacteria, and depth control is poor compared to a designed applicator.
Choice D reason: Gauze pads can’t deliver deeply; medication may stick or distribute poorly, reducing efficacy and comfort in vaginal administration settings.
