The patient receives warfarin (Coumadin). The nurse plans to teach the patient to avoid which foods that are served for lunch?
1. Tomato salad with basil
2. Whole-wheat bread with margarine
3. Salt substitute
4. Fettuccine Alfredo
Correct Answer: 1
Rationale: Tomatoes are high in vitamin K and must be avoided when a patient receives warfarin (Coumadin). Fettuccine Alfredo is not high in vitamin K so is not contraindicated when a patient receives warfarin (Coumadin). Salt substitute is not high in vitamin K so is not contraindicated when a patient receives warfarin (Coumadin). Whole-wheat bread with margarine is not high in vitamin K so is not contraindicated when a patient receives warfarin (Coumadin).
