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: Smoking impacts liver, not kidney excretion speed primarily. Liver metabolism accelerates instead. This choice errors per nursing pharmacology. It’s universally distinct, targeting the wrong organ for effect.
Choice B reason: Smoking induces liver enzymes, speeding drug metabolism significantly. This aligns with nursing pharmacology standards. It’s universally recognized, distinctly affecting drug efficacy and dosing needs.
Choice C reason: Smoking hastens, not slows, liver drug metabolism typically. This choice reverses nursing pharmacology facts. It’s universally distinct, contradicting known metabolic effects of smoking.
Choice D reason: Kidney excretion isn’t slowed by smoking; liver speeds metabolism. This choice misaligns with nursing standards. It’s universally distinct, errors in organ and effect direction.
Correct Answer is C
Explanation
Choice A reason: Lasix is given IV or orally, not subQ in the belly. Heparin fits this route, per nursing standards. This errors universally, distinctly missing subcutaneous administration.
Choice B reason: Digoxin is oral or IV, not subQ in the abdomen. Heparin is correct, per nursing pharmacology. This misaligns universally, distinctly unrelated to belly injections.
Choice C reason: Heparin is injected subQ in the belly, 2 inches from umbilicus, for anticoagulation. This matches, per nursing standards. It’s universally applied, distinctly effective.
Choice D reason: Phenobarbital is oral or IV, not subQ in the belly. Heparin suits this, per nursing pharmacology. This errors universally, distinctly off-target for route.
