病人開始服用華法林（Warfarin），下列哪些敘述顯示病人需要進一步衛教？（選所有適合的）
A nurse is educating a client starting warfarin therapy. Which statements by the client indicate a need for further teaching? (Select all that apply.)
- AI will keep my intake of green leafy vegetables consistent daily我會每天保持攝取綠色葉菜類的量一致
- BI will take an extra dose if I miss my medication✓ 正解如果我漏服藥物，我會多服一劑
- CI will use a soft-bristled toothbrush for oral care我會使用軟毛牙刷進行口腔護理
- DI will consult my provider before taking over-the-counter herbal supplements在服用非處方草本補充劑之前，我會諮詢我的醫師
- EI will stop taking the medication if I notice minor bruising✓ 正解如果我注意到輕微瘀青，我會停止服藥
華法林治療需維持藥物恆定濃度。B 是錯誤的，漏藥應遵照醫囑，不可自行補服。E 錯誤，輕微瘀青是常見副作用，不應自行停藥，應觀察是否有嚴重出血徵兆。A 正確，深綠色蔬菜含維生素 K 會拮抗藥效，須保持攝取恆定；C 正確，預防牙齦出血；D 正確，許多草藥會干擾凝血機制。
The client indicates a need for further teaching by stating they will take an extra dose if a medication is missed, as this significantly increases the risk of hemorrhage, and by planning to stop the medication upon noticing minor bruising, which could lead to rebound clotting. Consistent vitamin K intake, using soft-bristled toothbrushes, and consulting providers before taking supplements are appropriate safety measures.
美國常由衛教護理師或藥師進行 INR 監測衛教，台灣則多由醫師與護理師共同執行，衛教重點同樣為飲食與監測出血徵象。
