Why should clients who take warfarin (Coumadin) refrain from food items such as green leafy vegetables and soybeans?
Correct Answer: A
Rationale: Clients who take warfarin (Coumadin) should refrain from foods such as green leafy vegetables and soybeans because these foods contain high levels of Vitamin K. Vitamin K plays a crucial role in blood clotting, which may counteract the anti-coagulant effects of warfarin. Therefore, consuming large amounts of Vitamin K-rich foods can reduce the effectiveness of warfarin in preventing blood clots, leading to potential health risks. It is important for clients on warfarin therapy to maintain a consistent intake of Vitamin K in their diet to ensure the medication works effectively.
