華法林（Warfarin）是一種維生素 K 拮抗劑，其劑量調整極度依賴飲食中維生素 K 的攝取量。護理師必須教育病人穩定攝取富含維生素 K 的食物，不可大幅波動，以免影響凝血功能（INR）。此外，華法林會增加出血風險，病人需採取預防出血的居家措施，並在服用任何新藥前諮詢醫師，因為藥物交互作用會顯著改變藥效。
Clients prescribed warfarin must maintain a consistent intake of vitamin K-rich foods to prevent fluctuations in their INR levels, as significant dietary changes can alter drug efficacy. Essential safety instructions include using a soft-bristled toothbrush to minimize bleeding risk and reporting any unexplained bruising or hemorrhage immediately. Furthermore, clients should consult their provider before taking over-the-counter medications to avoid dangerous drug interactions.
