A client with atrial fibrillation is receiving warfarin (Coumadin). The nurse should reinforce which instruction?

  • A. Avoid foods high in vitamin K.
  • B. Increase intake of dairy products.
  • C. Limit intake of high-fiber foods.
  • D. Avoid protein-rich foods.
Correct Answer: A

Rationale: The correct answer is A: Avoid foods high in vitamin K. Clients taking warfarin need to be cautious with their vitamin K intake because vitamin K can counteract the effects of the medication. Therefore, it is essential to avoid foods high in vitamin K to maintain the therapeutic effects of warfarin. Choice B is incorrect because increasing dairy product intake is not specifically related to warfarin therapy. Choice C is incorrect as high-fiber foods do not interfere with warfarin therapy. Choice D is incorrect as protein-rich foods are not contraindicated with warfarin therapy.
