Review ATI Medical Surgical Proctored Exam 2023 With NGN Questions and Correct Answers related questions and content

A nurse is teaching a client who has a new prescription for warfarin about foods that affect the INR. The nurse should include in the teaching that which of the following foods interacts with this medication?

  • A. Orange juice
  • B. Cabbage
  • C. Beef stew
  • D. Vegetable oil
Correct Answer: B

Rationale: The correct answer is B: Cabbage. Cabbage is high in vitamin K, which can counteract the effects of warfarin, a medication that works by blocking the action of vitamin K in the blood. Consuming large amounts of foods high in vitamin K, like cabbage, can decrease the effectiveness of warfarin and increase the risk of blood clots. Orange juice (A), beef stew (C), and vegetable oil (D) do not significantly affect INR levels or interact with warfarin in the same way as vitamin K-rich foods like cabbage.
