A patient who is to receive a daily medication by the oral route has had nausea and vomiting for the last 24 hours. The best action to ensure that the patient receives the scheduled dose is to:
Withhold the dose for 1 hour and see whether the nausea subsides.
Have the patient take the pill with sips of water.
Have the patient take the pill with crackers.
Acquire an order to administer by the rectal or parenteral route.
The Correct Answer is D
Choice A reason: Withholding delays treatment; nausea may persist, risking vomiting of the dose if given later, reducing bioavailability and therapeutic effect over time.
Choice B reason: Sips of water won’t prevent vomiting; with ongoing nausea, the oral dose is likely expelled, decreasing absorption and failing to deliver the medication effectively.
Choice C reason: Crackers may worsen nausea or fail to retain the dose; vomiting risks remain high, compromising oral administration’s reliability in this acute condition.
Choice D reason: Rectal or parenteral routes bypass the stomach, ensuring delivery despite vomiting; this maintains therapeutic levels, critical for efficacy in a nauseated patient.

Correct Answer is B
Explanation
Choice A reason: Trade names are brand-specific; insurance denial of the brand rules this out, as it’s the costly formulation they won’t cover for the patient.
Choice B reason: Generic drugs, bioequivalent to brands, cost less; insurance favors them, ensuring the same active ingredient and efficacy at a lower price point.
Choice C reason: Chemical names describe molecular structure, not a formulation; they’re not dispensed as drugs, making this irrelevant to insurance or pharmacy.
Choice D reason: Proprietary is synonymous with brand; if insurance denies the brand, this option is also excluded, leaving generic as the viable substitute.
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.
