The oral method of medication administration would be used for all of the following EXCEPT:

Choice A reason: Three label checks ensure dosage accuracy, part of safe practice. All steps are correct, per nursing standards. It’s universally applied, distinctly reducing errors in medication administration.

Choice B reason: Verifying spelling and dosage across order, MAR, and label prevents mistakes. All are essential, per nursing pharmacology. It’s universally critical, distinctly ensuring drug accuracy.

Choice C reason: Rights (patient, drug, dose) are core to administration; all options support them. This is fundamental, per nursing standards. It’s universally upheld, distinctly guiding safe practice.

Choice D reason: All—label checks, verification, rights—combine for safe administration comprehensively. This aligns with nursing pharmacology standards, universally recognized and distinctly applied as best practice.

Choice A reason: Sedatives induce calm, not lower blood pressure directly. Vasodilators target BP reduction specifically. This choice errors per nursing pharmacology standards. It’s universally distinct as unrelated to BP management, lacking the required mechanism.

Choice B reason: Intermediate-acting defines duration, not BP-lowering action. Vasodilators reduce pressure effectively. This choice misaligns with nursing pharmacology definitions. It’s universally distinct, missing the functional role specified in the question.

Choice C reason: Vasodilators, like nitroglycerin, widen vessels, lowering BP efficiently. This matches nursing pharmacology standards precisely. It’s universally recognized, distinctly applied in practice for hypertension or angina management effectively.

Choice D reason: Vasoconstrictors raise BP, opposite of lowering it. Vasodilators fit the description accurately. This choice errors per nursing pharmacology principles. It’s universally distinct, contradicting the question’s intent entirely.
