護理師向一位被處方使用抗凝血劑的病人提供出院指導。下列哪項病人陳述表示需要進一步指導？
A nurse is providing discharge instructions to a client who has been prescribed an anticoagulant. Which statement by the client indicates a need for further teaching?
- AI will inform my dentist that I am taking this medication.我會告知牙醫師我正在服用此藥物。
- BI will report any unusual bruising or bleeding.我會回報任何異常的瘀青或出血。
- CI will increase my intake of leafy green vegetables.✓ 正解我會增加深綠色蔬菜的攝取量。
- DI will avoid taking aspirin or NSAIDs without checking with my doctor.在未諮詢醫師的情況下，我會避免服用阿斯匹靈或非類固醇消炎藥。
使用抗凝血劑（如 Warfarin）的病人需特別注意飲食中維生素 K（Vitamin K）的攝取量。維生素 K 會影響肝臟合成凝血因子的過程，直接拮抗 Warfarin 的抗凝效果。臨床教育重點在於「攝取量要穩定（Consistent）」，而非完全不吃或大量攝取，因為攝取量的劇烈波動會導致國際標準化比值（INR）失控，增加出血或血栓風險。
Patients on an anticoagulant such as warfarin must pay particular attention to dietary intake of vitamin K. Vitamin K affects the hepatic synthesis of clotting factors and directly antagonizes the anticoagulant effect of warfarin. The clinical teaching point is that intake should remain consistent rather than being eliminated entirely or markedly increased, because large fluctuations in intake destabilize the INR and increase the risk of bleeding or thrombosis.
