對於使用華法林(Warfarin)抗凝血治療的病人,護理師應優先關注哪項檢驗數據?

Which lab result should the nurse prioritize for a client on warfarin therapy?

  • AInternational Normalized Ratio (INR)✓ 正解
    國際標準化比值 (INR)
  • BHemoglobin level
    血紅素水平
  • CPlatelet count
    血小板計數
  • DActivated partial thromboplastin time (aPTT)
    活化部分凝血活素時間 (aPTT)
Explanation · 中文詳解

華法林(Warfarin)是口服抗凝血劑,其療效監測指標為 INR。aPTT 用於監測肝素(Heparin)。血小板數值雖重要但非評估華法林藥效的關鍵指標,血紅素則是用來評估有無出血副作用,但 INR 才是劑量調整依據。

The International Normalized Ratio (INR) is the standard monitoring test for warfarin therapy to ensure therapeutic efficacy and safety. While hemoglobin and platelet counts are important for detecting bleeding or other complications, they do not guide warfarin dosage adjustments. Activated partial thromboplastin time (aPTT) is used to monitor heparin therapy, not warfarin.

✦ 台美臨床差異

美台對於 Warfarin 的監測標準一致,皆使用 INR 值,且現今多導入床邊檢測機型(Point-of-care testing)。
