護理師照護一位準備進行心導管檢查的病人。在術前審閱哪項實驗室數值最為重要？
A nurse is caring for a client who is scheduled for a cardiac catheterization. Which laboratory result is most important for the nurse to review before the procedure?
- ASerum creatinine✓ 正解血清肌酸酐
- BHemoglobin level血紅素濃度
- CWhite blood cell count白血球計數
- DPotassium level鉀離子濃度
心導管術中使用的顯影劑具腎毒性，若病人原本腎功能不佳（以血清肌酸酐評估），發生顯影劑誘發性腎病變（CIN）的風險極高。護理師需確認腎功能，以便術前給予足夠靜脈補液或通知醫師調整顯影劑劑量。雖然鉀離子對心律重要，但在預防處置風險中，腎功能是顯影劑檢查的首要考量。
The contrast media used during cardiac catheterization is nephrotoxic. If renal function is already impaired (as assessed by serum creatinine), the risk of contrast-induced nephropathy (CIN) is very high. The nurse must verify renal function so that adequate IV hydration can be given preoperatively or so the provider can be notified to adjust the contrast dose. Although potassium is important for cardiac rhythm, renal function is the primary consideration in preventing procedural risk with contrast studies.
美國 RN 需主動篩選異常報告並依 protocol 延後檢查或通知；台灣臨床護理師亦需核對，但醫師通常會預先審核。
