NCLEX Question of the Day
Review the question, check the correct answer, and read the rationale before tomorrow's prompt arrives.
A nurse is reviewing discharge instructions with a client who has been prescribed warfarin. Which of the following foods should the nurse advise the client to limit due to their high vitamin K content?
-
Fish.
-
Whole grains.
-
Bananas.
-
Correct answer Leafy green vegetables.
Rationale
Leafy green vegetables are high in vitamin K, which can antagonize the anticoagulant effects of warfarin. Clients should be advised to maintain a consistent intake of vitamin K to avoid fluctuations in their International Normalized Ratio (INR) levels. Bananas, whole grains, and fish do not have high vitamin K content.
