病人預計進行需使用碘顯影劑的心導管檢查。術前最重要的檢驗數值為何？
A client is scheduled for a cardiac catheterization using an iodine-based contrast dye. Which laboratory result is most critical to review before the procedure?
- AHemoglobin A1c糖化血色素
- BSerum albumin血清白蛋白
- CCreatinine level✓ 正解肌酸酐濃度
- DPlatelet count血小板計數
碘顯影劑（iodine-based contrast dye）經由腎臟代謝，具有潛在的腎毒性。若病人原本腎功能不佳，顯影劑的使用可能誘發顯影劑誘發性腎病（Contrast-induced nephropathy, CIN），導致急性腎功能衰竭。因此，術前評估腎功能指標（如肌酸酐 Creatinine 或腎絲球過濾率 GFR）對於判斷病人是否能安全代謝顯影劑至關重要。護理師必須確保此數值已在醫師審視範圍內，以防嚴重腎損害。
Iodine-based contrast dye is excreted by the kidneys and is potentially nephrotoxic. In clients with pre-existing renal impairment, contrast use can precipitate contrast-induced nephropathy (CIN) and lead to acute renal failure. Therefore, preprocedural assessment of renal function (such as serum creatinine or GFR) is critical for determining whether the client can safely metabolize the contrast dye. The nurse must ensure this value has been reviewed by the provider to prevent serious renal injury.
