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:

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.
