The nurse recognizes that which food on a client's tray could cause a drug-food interaction with warfarin (Coumadin)?

Question

Quizplus · Accepted Answer

Spinach contains a high amount of vitamin K, which can interfere with the effectiveness of warfarin by decreasing its anticoagulant activity. Therefore, it is important for clients taking warfarin to avoid or limit the intake of foods that are high in vitamin K, such as spinach. Bananas, toasted cheese sandwich, and iced tea do not have significant interactions with warfarin.
