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

Answer and Explanation

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 A

Explanation

Choice A reason: Herbal remedies lack FDA safety data; in pregnancy, untested substances risk fetal harm (e.g., teratogenicity), making this a critical caution.

Choice B reason: Claiming safety is false; many herbs (e.g., St. John’s Wort) affect pregnancy adversely, and without evidence, this misleads the patient dangerously.

Choice C reason: Consistency isn’t required; herbal products vary widely in potency, and this false assurance ignores regulatory gaps in supplement standardization.

Choice D reason: Labels help, but warnings are inconsistent; this shifts responsibility without addressing the lack of proven safety, a more pressing prenatal concern.

A. 90-degree B. 45-degree C. 15-degree D. 25-degree

Correct Answer is A

Explanation

Choice A reason: IM injections use a 90-degree angle; this ensures deep muscle penetration for average-weight adults, optimizing drug absorption into vascular tissue.

Choice B reason: 45 degrees is for subcutaneous injections; it’s too shallow for IM, risking fat deposition instead of muscle, reducing efficacy in this context.

Choice C reason: 15 degrees is far too shallow; it’s not a standard angle, likely depositing drug in skin layers, failing to reach muscle for intended absorption.

Choice D reason: 25 degrees mimics subcutaneous; it doesn’t reach muscle depth, compromising IM delivery and therapeutic effect in an average-weight client.
