病人正在進行肝素（Heparin）持續輸注。護理師應監測哪項檢驗數值？
A client is receiving a continuous heparin infusion. Which laboratory value should the nurse monitor?
- ABleeding time出血時間
- BInternational Normalized Ratio (INR)國際標準化比值 (INR)
- CProthrombin time (PT)凝血酶原時間 (PT)
- DActivated partial thromboplastin time (aPTT)✓ 正解活化部分凝血活酶時間 (aPTT)
— Explanation · 中文詳解 —
肝素（Heparin）的藥效監測指標為 aPTT。當病人處於肝素治療範圍時，aPTT 通常需維持在正常值的 1.5 到 2.5 倍。PT 與 INR 則是用於監測口服抗凝血劑華法林（Warfarin）的指標。出血時間檢查在現代臨床已不作為常規的抗凝血監測手段。
The activated partial thromboplastin time (aPTT) is the standard laboratory test used to monitor the therapeutic effectiveness of continuous heparin infusions. The goal is typically to maintain the aPTT at 1.5 to 2.5 times the control value. Prothrombin time (PT) and INR are used to monitor warfarin therapy, not heparin.
✦ 台美臨床差異
台美臨床對於肝素給藥的監測指標高度一致，均以 aPTT 為主。
