— Explanation · 中文詳解 —
深綠色蔬菜（如菠菜）含有大量維生素 K，會拮抗華法林（Warfarin）的抗凝血效果，導致凝血功能異常。飲食中維生素 K 的攝取量必須維持穩定，不可大幅變動。其他選項（D、B、C）對華法林效價影響較小。
Dark green vegetables such as spinach contain large amounts of vitamin K, which antagonizes the anticoagulant effect of warfarin and can result in unstable coagulation. Dietary vitamin K intake must be kept consistent and should not fluctuate significantly. The other options (D, B, C) have minimal impact on warfarin's effectiveness.
✦ 台美臨床差異
美國診所多配有抗凝血劑衛教專員；台灣病患多在門診由醫師或藥師簡單提醒，護理師衛教常被忽略。
