Explanation · 中文詳解

華法林(Warfarin)是一種維生素 K 拮抗劑,治療指數窄,治療目標通常為 INR 2.0-3.0。當 INR 達到 5.5 時,表示凝血功能受到過度抑制,出血風險顯著增加。根據 NCLEX 的安全優先原則(Safety/Priority),護理師應先評估病人是否已經發生出血跡象。檢查黏膜出血、血尿、瘀斑或黑便,能協助判斷臨床嚴重程度。隨後才應考慮暫停給藥或聯絡醫師醫囑使用維生素 K(Vitamin K)拮抗作用。

An INR of 5.5 indicates excessive anticoagulation and a significantly increased risk of hemorrhage, making safety assessment the top priority. The nurse must first check for signs of active bleeding, such as mucosal bleeding, hematuria, or bruising, to determine the clinical severity before holding medication or administering vitamin K.
