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 C
Explanation
Choice A reason: One 5-mg tablet provides only 5 mg, far below the 15 mg ordered; this underdose fails to control hypertension effectively, risking cardiovascular complications like stroke or heart failure.
Choice B reason: Two tablets yield 10 mg, still short of 15 mg; this insufficient dose wouldn’t achieve therapeutic blood pressure reduction, leaving the patient at risk for hypertensive damage.
Choice C reason: Three 5-mg tablets equal 15 mg, matching the order precisely; this dose effectively inhibits angiotensin-converting enzyme, lowering blood pressure to a therapeutic range safely.
Choice D reason: Four tablets deliver 20 mg, exceeding the order; this overdose could cause hypotension, dizziness, or renal impairment due to excessive ACE inhibition beyond therapeutic needs.
Correct Answer is B
Explanation
Choice A reason: The barrel holds the medication; it’s the main body, not typically #7, and its static role doesn’t involve direct manipulation like other parts.
Choice B reason: The plunger, often numbered high in diagrams, moves to draw or inject; its dynamic function in volume control makes it a likely #7 candidate.
Choice C reason: The needle pierces tissue; usually a lower number, it’s distinct from the syringe’s operational core, less likely to be #7 in standard layouts.
Choice D reason: The tip connects the needle; a minor component, it’s rarely highlighted as #7, overshadowed by the plunger or barrel in functional importance.
