A hospitalized client is prescribed warfarin (Coumadin). The nurse teaches the client to avoid which food on the lunch selection menu?
1. Whole-wheat bread with margarine
2. Roast beef
3. Salt substitute
4. Broccoli salad
Correct Answer: 4
Rationale 1: Whole-wheat bread with margarine is not high in vitamin K, and so is not contraindicated when a client receives warfarin (Coumadin).
Rationale 2: Roast beef is not high in vitamin K, and so is not contraindicated when a client receives warfarin (Coumadin).
Rationale 3: Salt substitute is not high in vitamin K, and so is not contraindicated when a client receives warfarin (Coumadin).
Rationale 4: Broccoli is high in vitamin K, and must be avoided when a client receives warfarin (Coumadin).
Global Rationale: Broccoli is high in vitamin K, and must be avoided when a client receives warfarin (Coumadin). Whole-wheat bread with margarine, roast beef, and salt substitute are not high in vitamin K, and so these foods are not contraindicated when a client receives warfarin (Coumadin).
