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: Tear duct drains; it doesn’t hold ophthalmic meds. Conjunctival sac is correct. This errors per nursing standards. It’s universally distinct, wrong site.
Choice B reason: Conjunctival sac holds ophthalmic meds for absorption effectively. This fits nursing pharmacology standards. It’s universally applied, distinctly the right area.
Choice C reason: Sclera is eye surface, not a med site. Conjunctival sac is used. This misaligns with nursing pharmacology. It’s universally distinct, incorrect.
Choice D reason: Canthus, eye corner, isn’t for med administration. Conjunctival sac fits. This errors per nursing standards. It’s universally distinct, off-target.
Correct Answer is C
Explanation
Choice A reason: Antihistamines block histamine, not raise HR or BP. Epinephrine fits emergency needs. This errors per nursing pharmacology. It’s universally distinct, lacking stimulatory emergency effects.
Choice B reason: Sedatives reduce activity, not increase HR or BP. Epinephrine acts oppositely. This choice reverses nursing standards. It’s universally distinct, unsuitable for emergency stimulation.
Choice C reason: Epinephrine boosts HR, BP, and dilates bronchi in emergencies. This matches nursing pharmacology standards. It’s universally applied, distinctly effective for acute life-saving interventions.
Choice D reason: Hormones vary; epinephrine specifically meets all criteria emergently. This lacks precision per nursing standards. It’s universally distinct, too vague for the question’s intent.
