一位病人服用華法林(Warfarin)。護理師應監測下列哪個實驗室檢查值?
A patient is prescribed warfarin. Which laboratory result should the nurse monitor?
- APlatelet count血小板計數
- BHemoglobin血紅素
- CPTT部分凝血活酶時間
- DPT/INR✓ 正解凝血酶原時間/國際標準比值
— Explanation · 中文詳解 —
華法林透過抑制維生素 K 依賴性凝血因子發揮作用,臨床上透過測量凝血酶原時間(PT)及其國際標準化比值(INR)來評估療效。PTT 用於監測肝素(Heparin)。血小板與血色素雖重要,但非監測華法林療效的指標。
Warfarin acts by inhibiting vitamin K-dependent clotting factors. Its therapeutic effect is monitored clinically by measuring prothrombin time (PT) and the international normalized ratio (INR). PTT is used to monitor heparin. Platelet count and hemoglobin, while important, are not indicators of warfarin efficacy.
✦ 台美臨床差異
美台醫療系統在華法林衛教上極為相似,皆強調病人的 INR 數據與飲食中維生素 K 的攝取一致性。
