護理師對服用 warfarin 的病人進行出院衛教。下列哪一句話顯示病人已理解衛教內容？
A nurse is providing discharge education to a client prescribed warfarin. Which of the following statements by the client indicates an understanding of the teaching?
- AI will increase my intake of dark green leafy vegetables我會增加深色葉菜蔬菜的攝取量
- BI will use a soft-bristled toothbrush for oral hygiene✓ 正解我會使用軟毛牙刷進行口腔衛生
- CI will discontinue the drug if I notice minor bruising如果我注意到輕微瘀青，我會停用這種藥物
- DI can take aspirin if I experience a headache如果我頭痛，我可以服用阿斯匹靈
Warfarin 為維生素 K 拮抗劑。使用軟毛牙刷可避免牙齦出血，這是抗凝血治療的基本出血防護措施。深綠色蔬菜含有大量維生素 K 會干擾藥效；不可隨意服用阿斯匹靈以免增加出血風險；瘀青是常見副作用，不可擅自停藥。
Warfarin is a vitamin K antagonist. Using a soft-bristled toothbrush helps prevent gingival bleeding and is a basic bleeding-prevention measure during anticoagulant therapy. Dark green leafy vegetables are high in vitamin K and can interfere with the drug's effect; aspirin should not be taken without provider approval because it increases bleeding risk; and minor bruising is a common adverse effect, so the medication should not be discontinued independently.
台灣病人對中藥與保健食品（如當歸、人蔘）併用的警覺性較低，美國護理師常需額外衛教避免草本補充劑。
