When preparing medications for delivery to an assigned patient, the nurse should check each medication for accuracy of drug and dose:
One time.
Two times.
Three times.
Five times.
The Correct Answer is C
Choice A reason: Checking medications only once increases the likelihood of errors. Safe practice requires multiple verification steps.
Choice B reason: While better than a single check, verifying only twice may still miss potential discrepancies in drug or dosage accuracy.
Choice C reason: The three-check system (when retrieving, preparing, and administering medication) minimizes errors, ensuring patient safety through consistent validation at each step.
Choice D reason: Excessive verification may delay administration, reducing practicality without significantly improving safety beyond three checks.

Correct Answer is C
Explanation
Choice A reason: Four times (6:00 a.m., noon, 6:00 p.m., midnight) is QID, not TID; TID means three times daily, and this schedule overdoses the patient unnecessarily.
Choice B reason: Six times daily is every 4 hours, not TID; this exceeds the three-dose requirement, risking toxicity or side effects from excessive administration frequency.
Choice C reason: 9:00 a.m., 1:00 p.m., 5:00 p.m. is TID; spaced 8 hours apart, it aligns with standard three-times-daily dosing, ensuring consistent therapeutic levels safely.
Choice D reason: Meal and bedtime timing is vague; without fixed hours, it risks uneven dosing intervals, potentially disrupting pharmacokinetics and efficacy of the medication.
Correct Answer is B
Explanation
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.
