護理師即將給予病人華法林 (Warfarin)。給藥前應檢查哪項實驗室數值？
A nurse is administering a dose of warfarin to a client. Which laboratory value should the nurse review before administering the medication?
- AHemoglobin and Hematocrit血色素與血球容積比
- BPlatelet count血小板計數
- CActivated Partial Thromboplastin Time (aPTT)活化部分凝血活酶時間 (aPTT)
- DProthrombin Time (PT) and INR✓ 正解凝血酶原時間 (PT) 與國際標準比值 (INR)
— Explanation · 中文詳解 —
華法林是一種維生素 K 拮抗劑，透過抑制凝血因子合成發揮作用。臨床上使用國際標準化比值 (INR) 來監測其抗凝血療效，標準值通常需維持在 2.0-3.0 之間。B 是肝素 (Heparin) 的監測指標，切勿混淆。
Warfarin is a vitamin K antagonist, and its therapeutic effect is monitored using the Prothrombin Time (PT) and International Normalized Ratio (INR). The target INR for most clients is typically between 2.0 and 3.0. The aPTT is used to monitor heparin therapy, not warfarin.
✦ 台美臨床差異
兩地臨床實驗室報告均提供 INR 值，護理師需確認該數值是否在治療範圍內。
