Which of the following statements by a client receiving warfarin (Coumadin) indicates the need for further teaching?
"I use a laxative every other day."
"I use antacids once in a while."
"I ate some corn yesterday."
"I always have aspirin with me to take for my headaches."
The Correct Answer is D
Choice A reason: Laxatives don’t significantly affect warfarin’s anticoagulation; this is safe. Aspirin increases bleeding risk, needing teaching, per nursing pharmacology. It’s a universal distinction, distinctly unrelated to warfarin’s primary concerns.
Choice B reason: Occasional antacids minimally impact warfarin; this is acceptable. Aspirin’s bleeding risk is the issue, per nursing standards. This doesn’t require teaching, universally distinct from anticoagulation education.
Choice C reason: Corn has negligible vitamin K; it doesn’t affect warfarin. Aspirin use needs correction, per nursing pharmacology. This is safe, universally distinct from dietary teaching for anticoagulants.
Choice D reason: Aspirin with warfarin heightens bleeding risk significantly; this requires teaching. Other statements are benign, per nursing standards. It’s a universal concern, distinctly critical for safe anticoagulation management.

Correct Answer is B
Explanation
Choice A reason: Label away aids reading, but thumbnail ensures dose accuracy. This errors per nursing standards. It’s universally distinct, less precise than thumbnail method.
Choice B reason: Thumbnail on cup line guarantees exact liquid dose poured. This aligns with nursing pharmacology standards. It’s universally applied, distinctly accurate for administration.
Choice C reason: Returning surplus risks contamination; thumbnail prevents overpouring. This choice misaligns with nursing safety. It’s universally distinct, unsafe for medication handling.
Choice D reason: Below-eye level risks misjudgment; thumbnail is precise. This errors per nursing pharmacology standards. It’s universally distinct, less accurate than standard.
Correct Answer is C
Explanation
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.
