— Explanation · 中文詳解 —
華法林（warfarin）的治療目標是透過監測 INR 來確保抗凝血效果，同時平衡出血風險。一般治療範圍（therapeutic range）為 2.0 至 3.0。當 INR 落在 2.5 時，代表藥物效果在安全且有效的範圍內，護理師應按醫囑給藥。臨床上，若 INR 超出此範圍，才需考慮暫停給藥或聯繫醫師。
The therapeutic INR range for warfarin therapy is typically 2.0 to 3.0. Since the client's INR is 2.5, it falls within the safe and effective range, so the nurse should administer the prescribed dose and document it.
