一位第二型糖尿病病人獲處方使用二甲雙胍(metformin),給藥前護理師應優先評估下列哪項數據?

A client with type 2 diabetes mellitus is prescribed metformin. Which assessment finding should the nurse prioritize prior to administering the dose?

  • ABlood pressure reading
    血壓讀值
  • BFasting blood glucose level
    空腹血糖濃度
  • CSerum potassium level
    血清鉀離子濃度
  • DSerum creatinine level✓ 正解
    血清肌酸酐濃度
Explanation · 中文詳解

二甲雙胍主要經由腎臟排泄,若病人出現腎功能異常,藥物容易蓄積體內引發乳酸中毒(Lactic Acidosis),這是此藥最嚴重的副作用。因此,監測肌酸酐與評估腎絲球過濾率是臨床用藥安全的核心要求。其他選項雖為糖尿病照護重點,但皆非導致此藥急性併發症的關鍵因子。

Metformin is contraindicated in clients with renal impairment because reduced kidney function increases the risk of lactic acidosis, a serious complication. Therefore, checking serum creatinine levels is the priority assessment before administration to ensure patient safety.

✦ 台美臨床差異

台灣醫院系統常有自動偵測系統,若肌酸酐數值異常,電腦會警示護理師,但護理師仍需具備臨床判斷能力。
