一位深部靜脈栓塞病人正在接受肝素（Heparin）滴注，護理師應監測下列哪個檢驗值？
A nurse is caring for a client with a deep vein thrombosis (DVT) receiving a heparin infusion. Which laboratory value should the nurse monitor?
- AActivated partial thromboplastin time (aPTT)✓ 正解活化部分凝血活酶時間 (aPTT)
- BPlatelet count血小板計數
- CInternational Normalized Ratio (INR)國際標準化比值 (INR)
- DProthrombin time (PT)凝血酶原時間 (PT)
— Explanation · 中文詳解 —
肝素（Heparin）治療需要監測 aPTT 以維持在治療範圍內。PT/INR 是用於監測 Warfarin 的指標。雖然血小板（Platelet）對於偵測肝素誘發血小板低下症（HIT）也很重要，但在常規評估肝素抗凝血效果時，aPTT 是標準指標。
Heparin therapy is monitored using aPTT to keep it within the therapeutic range. PT/INR is used to monitor warfarin. While platelet count is important for detecting heparin-induced thrombocytopenia (HIT), aPTT is the standard test for evaluating heparin's anticoagulant effect.
✦ 台美臨床差異
兩國臨床監測指標一致，均使用 aPTT 監測肝素。
