Warfarin 是一種維生素 K 拮抗劑，透過抑制肝臟合成凝血因子來發揮抗凝血作用。飲食中的維生素 K 攝取量會直接影響 Warfarin 的藥效。護理師衛教的重點不在於「戒斷」綠色蔬菜，而在於「維持攝取量的一致性」，以便醫師根據病人的 INR（國際標準化比值）調整藥物劑量，避免 INR 波動導致的出血或栓塞風險。
Clients on warfarin must maintain a consistent daily intake of vitamin K-rich foods, such as green leafy vegetables, to prevent fluctuations in the International Normalized Ratio (INR). Consistency allows for accurate dosage adjustments based on INR levels, minimizing the risks of bleeding or thromboembolism associated with erratic dietary habits.
