護理師欲給予病人 Warfarin,給藥前應檢查哪項實驗室數據?
A nurse is administering a dose of warfarin to a client. Which laboratory value should the nurse check prior to administration?
- APTT部分凝血活酶時間
- BHematocrit血球容積比
- CPlatelet count血小板計數
- DPT/INR✓ 正解凝血酶原時間/國際標準比值
— Explanation · 中文詳解 —
Warfarin(Coumadin)是一種口服抗凝血劑,其治療效果是透過監測凝血酶原時間及其國際標準化比值(PT/INR)來評估的。PTT 是用來監測肝素(Heparin)的,兩者不可混淆。在用藥前確認此數值,可避免抗凝血過度導致出血風險。
Warfarin (Coumadin) is an oral anticoagulant whose therapeutic effect is evaluated by monitoring the prothrombin time and its international normalized ratio (PT/INR). PTT is used to monitor heparin, and the two must not be confused. Confirming this value before administration helps avoid the bleeding risk from excessive anticoagulation.
✦ 台美臨床差異
兩地均依循 INR 指標進行劑量調整,但美國臨床普遍使用電子化決策輔助系統協助護理師核對劑量。
