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 A
Explanation
Choice A reason: Tolerance reflects receptor desensitization or enzyme induction; higher doses compensate for reduced drug efficacy, a common pharmacological adaptation.
Choice B reason: Organ failure affects metabolism, not tolerance; tolerance is a cellular response, not solely a failure of liver or kidney drug clearance mechanisms.
Choice C reason: Stable dosing contradicts tolerance; if tolerance develops, efficacy drops, necessitating dose increases, not maintenance, to achieve therapeutic levels.
Choice D reason: Non-adherence may alter response, but tolerance occurs with consistent use; it’s a physiological adaptation, not a result of misuse or skipping doses.
Correct Answer is ["A"]
Explanation
Choice A reason: Multiple pharmacies increase polypharmacy risk; 16 prescriptions across four sources raise chances of duplication or interactions, lacking centralized oversight.
Choice B reason: Five hypertension drugs signal polypharmacy; excessive medications for one condition heighten interaction risks, potentially causing adverse effects or toxicity.
Choice C reason: Daughter’s help with eyedrops aids compliance; this single-task assistance doesn’t inherently increase drug numbers or polypharmacy-related risks.
Choice D reason: Weekly warfarin tests monitor safety; this manages one drug’s effect, not indicating polypharmacy, but rather appropriate therapeutic oversight.
Choice E reason: Allergies affect drug choice, not quantity; this doesn’t contribute to polypharmacy, as it’s a sensitivity issue, not a medication count concern.
