華法林（Warfarin）的治療監測指標為 INR（國際標準化比值）。雖然治療目標通常為 2.0-3.0，但對於剛開始治療或處於特定病況的病人，INR 的波動是常見的。1.5 的數值雖然偏低，但並未達到需要立即停藥或介入的危險程度（如出血風險），護理師應依照預定醫囑給藥，並確保後續持續監測即可，這符合臨床用藥的持續性原則。
Warfarin therapy is monitored using the INR (International Normalized Ratio). Although the therapeutic target is usually 2.0-3.0, INR fluctuations are common in clients who have recently started therapy or have particular clinical conditions. A value of 1.5 is below target but not at a level that requires immediate withholding or intervention (such as bleeding risk). The nurse should administer the scheduled dose and continue monitoring, which is consistent with the principle of continuous medication management.
