華法林（Warfarin）是一種維生素 K 拮抗劑（Vitamin K antagonist），透過抑制肝臟凝血因子合成發揮作用。飲食中攝取維生素 K 的量若大幅波動，會直接影響 INR（國際標準化比值）數值。護理教學的核心重點是「穩定」，而非「限制」，病人需將深綠色葉菜類的攝取量維持在平日的一致水準，以利醫師調整藥物劑量，維持治療性 INR 範圍。
Clients taking warfarin should maintain a consistent intake of green leafy vegetables because they contain vitamin K, which directly antagonizes the medication's effects. Consistency in dietary vitamin K helps stabilize INR levels, whereas significant fluctuations can lead to therapeutic failure or bleeding risks.
