A drug that lowers blood pressure is called a(n):
Sedative
Intermediate-acting
Vasodilator
Vasoconstrictor
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A reason: Left-side (Sim’s) aligns with colon, easing rectal administration. This fits nursing pharmacology standards precisely. It’s universally recognized, distinctly effective for suppositories/enemas.
Choice B reason: Supine limits rectal access; left-side is optimal instead. This choice errors per nursing standards. It’s universally distinct, impractical for rectal delivery.
Choice C reason: Prone hinders rectal insertion; left-side aids it better. This misaligns with nursing pharmacology principles. It’s universally distinct, ineffective for administration.
Choice D reason: Right-side doesn’t match colon anatomy as well. Left-side is standard per nursing standards. This errors universally, distinctly less effective.
Correct Answer is A
Explanation
Choice A reason: Cooling a soft suppository in foil under cold water firms it for insertion. This is practical, per nursing pharmacology. It’s universally applied, distinctly effective for administration.
Choice B reason: Not administering skips needed therapy; cooling resolves softness safely. This overreacts, per nursing standards. It’s universally distinct, errors in patient care continuity.
Choice C reason: Inserting a soft suppository reduces efficacy and comfort; cooling is better. This risks failure, per nursing pharmacology. It’s universally distinct, a poor choice.
Choice D reason: Returning to pharmacy delays treatment; cooling is faster and sufficient. This errors, per nursing standards. It’s universally distinct, less practical than cooling.
