一位病人正在服用華法林（Warfarin）。護理師應監測哪些實驗室數據？（選所有適合的）
A nurse is caring for a client receiving warfarin. Which laboratory results should the nurse monitor? (Select all that apply.)
- APT✓ 正解凝血酶原時間
- BINR✓ 正解國際正常化比值
- CaPTT活化部分凝血活酶時間
- DPlatelet count血小板計數
- ESerum albumin血清白蛋白

華法林作用於維生素 K 依賴性凝血因子，臨床上透過測定凝血酶原時間（PT）及其國際標準化比值（INR）來評估療效。aPTT 主要用於監測肝素（Heparin）。雖然血小板計數在某些抗凝血治療下需要監測，但並非華法林療效監控的核心指標。
Warfarin acts on vitamin K-dependent coagulation factors, and its efficacy is clinically evaluated by measuring the prothrombin time (PT) and its International Normalized Ratio (INR). aPTT is used primarily to monitor heparin. Although platelet counts must be monitored during some forms of anticoagulant therapy, they are not the core indicator for monitoring warfarin therapy.
✦ 台美臨床差異
台美臨床皆使用 INR 作為主要依據，台灣門診抗凝血中心亦非常普及。
