護理師對一位新開立 Warfarin 的病人進行出院指導。下列哪些病人敘述顯示需要進一步衛教？（選所有適合的）
A nurse is providing discharge instructions to a client with a new prescription for warfarin. Which client statements indicate a need for further teaching? (Select all that apply.)
- AI will eat more green leafy vegetables to ensure I get enough vitamins.✓ 正解我會多吃綠色葉菜，以確保攝取足夠的維生素。
- BI will use a soft-bristled toothbrush for my daily oral care.我每天口腔護理時會使用軟毛牙刷。
- CI will take an aspirin if I get a headache.✓ 正解如果我頭痛，我會服用阿斯匹靈。
- DI will report any unusual bruising or bleeding to my doctor.我會向醫師報告任何異常的瘀青或出血。
- EI will take my medication at the same time each day.我每天會在固定時間服藥。
Warfarin 作用機制受維生素 K 影響，攝取大量綠色蔬菜會降低藥效（A 錯誤）。阿斯匹靈（Aspirin）為抗血小板藥物，併用會大幅增加出血風險（C 錯誤）。軟毛牙刷（B 正確）、報告出血（D 正確）、定時服藥（E 正確）皆為衛教重點。
Warfarin's mechanism of action is influenced by vitamin K; consuming large amounts of leafy green vegetables will reduce its effect (option A incorrect). Aspirin is an antiplatelet agent, and combined use significantly increases the risk of bleeding (option C incorrect). A soft-bristled toothbrush (B, correct), reporting bleeding (D, correct), and taking the medication at a consistent time (E, correct) are all key teaching points.
美國藥師常參與抗凝血劑衛教，台灣則多由護理師與心臟科專科醫師共同負責衛教流程。
