護理師向服用 Warfarin 的病人進行衛教，下列哪些病人的說法顯示需要進一步指導？（選所有適合的）
A nurse is providing discharge teaching to a client with a new prescription for warfarin. Which statements by the client indicate a need for further instruction? (Select all that apply.)
- AI will increase my intake of dark green leafy vegetables✓ 正解我會增加深色葉菜類的攝取
- BI will use a soft-bristled toothbrush for my teeth我會使用軟毛牙刷刷牙
- CI should take an aspirin if I develop a headache✓ 正解如果我頭痛，我應該服用阿斯匹靈
- DI will notify my doctor if I notice black, tarry stools如果我注意到黑色柏油樣糞便，我會通知醫師
- EI plan to stop taking my medication if I experience minor bruising✓ 正解如果我出現輕微瘀青，我打算停止服藥
Warfarin 衛教重點在於維生素 K 攝取的恆定性與出血防範。增加深綠色蔬菜會抵銷藥效（A）；服用阿斯匹靈會增加出血風險（C）；自行停藥若因輕微瘀青是不必要的（E）。護理師需確保病人了解，輕微瘀青是常見副作用，但若出現黑便、異常出血則需立即通報。教育的目的在於提升服藥遵從性與安全性，預防嚴重併發症。
Warfarin teaching emphasizes a consistent intake of vitamin K and bleeding precautions. Increasing dark green leafy vegetables counteracts the medication effect (A); taking aspirin increases bleeding risk (C); and stopping the medication for minor bruising is unnecessary (E). The nurse must ensure the client understands that minor bruising is a common adverse effect, but that black stools or unusual bleeding require immediate reporting. The goal of education is to enhance adherence and safety and to prevent serious complications.
