下列哪位病人的敘述顯示需要對華法林（Warfarin）療法進行再衛教？
Which of the following client statements indicates a need for further education on warfarin therapy?
- AI will take my medication at the same time every day我會每天在同一時間服藥
- BI will avoid changes in my intake of leafy green vegetables我會避免改變深綠色蔬菜的攝取量
- CI will inform my dentist that I take this medication我會告知牙醫我正在服用此藥物
- DI will increase my intake of vitamin K-rich foods✓ 正解我會增加富含維生素K食物的攝取
— Explanation · 中文詳解 —
Warfarin 是維生素 K 拮抗劑。攝取過多維生素 K（如深綠色蔬菜）會抵銷藥效，導致 INR 數值下降。正確衛教應是維持飲食習慣穩定，而非增加攝取。因此病人說「增加攝取」顯示其對藥物機轉不了解。
Warfarin is a vitamin K antagonist, so increasing intake of vitamin K-rich foods reduces its anticoagulant effectiveness. Patients should be educated to maintain a consistent diet rather than significantly altering their vitamin K consumption.
