A primary health-care provider prescribes a medication that must be administered transdermal. Which information about the route of administration does the nurse understand is related to a drug prescribed to be administered transdermal?
Inhaled into the respiratory tract
Absorbed through the skin
Inserted into the rectum
Dissolved under the tongue
The Correct Answer is B
Choice A reason: Inhalation targets lungs; transdermal means skin absorption, not respiratory, and this route doesn’t match the prescribed method’s pharmacokinetic profile.
Choice B reason: Transdermal drugs absorb through skin layers; this delivers medication systemically via dermal capillaries, bypassing first-pass metabolism, as intended by the order.
Choice C reason: Rectal administration uses suppositories; transdermal is skin-based, not mucosal, and this route doesn’t align with the prescribed absorption method.
Choice D reason: Sublingual dissolves under the tongue; transdermal is cutaneous, not oral, and this differs entirely from the skin-based delivery system specified.

Correct Answer is D
Explanation
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
Step 1 is 2 hours × 60 minutes = 120 minutes.
Step 2 is (250 mL ÷ 120 minutes) × 15 gtts/mL.
Step 3 is 2.08333 mL/min × 15 gtts/mL = 31.24995 gtts/min.
Step 4 is 31.24995 rounded to the nearest whole number is 31.
The final calculated answer is 31 gtts/min.
