一位病人正在接受華法林(Warfarin)治療,護理師應監測下列哪項實驗室數值以確保藥效?

A client is receiving warfarin therapy. Which lab result should the nurse monitor to ensure the effectiveness of the medication?

  • APlatelet count
    血小板計數
  • BActivated Partial Thromboplastin Time (aPTT)
    活化部分凝血活酶時間 (aPTT)
  • CInternational Normalized Ratio (INR)✓ 正解
    國際標準化比值 (INR)
  • DHemoglobin and hematocrit
    血紅素和血球容積比
Explanation · 中文詳解

華法林(Warfarin)是維生素K拮抗劑,其抗凝血效果需透過國際標準化比值(INR)來監測。aPTT 用於監測肝素(Heparin)的藥效,而非華法林。監測 INR 可確保病人維持在治療範圍內(通常為 2.0-3.0),避免出血風險(過高)或血栓復發風險(過低)。

Warfarin is a vitamin K antagonist whose anticoagulant effect is monitored using the International Normalized Ratio (INR). aPTT is used to monitor heparin therapy, not warfarin. Monitoring INR ensures that the client is kept within the therapeutic range (typically 2.0 to 3.0), avoiding both the risk of bleeding (if too high) and recurrent thrombosis (if too low).

✦ 台美臨床差異

台美臨床皆使用 INR 監測華法林,但台灣民眾對飲食中維生素K攝取(如深綠色蔬菜)的衛教需要更多本土化建議。
