一位高血壓病人預計進行需使用顯影劑的檢查，護理師應向醫師回報下列哪個檢驗值？
A client with a history of hypertension is scheduled for a diagnostic procedure requiring contrast dye. Which lab value should the nurse report to the provider?
- AHemoglobin 13.5 g/dL血紅素 13.5 g/dL
- BWhite blood cell count 8,000/mm³白血球計數 8,000/mm³
- CSerum creatinine 2.1 mg/dL✓ 正解血清肌酸酐 2.1 mg/dL
- DSerum potassium 4.2 mEq/L血清鉀 4.2 mEq/L

含碘顯影劑具有腎毒性，若病人腎功能不全（如肌酸酐值升高），顯影劑可能導致顯影劑引發之急性腎損傷（CIN）。肌酸酐 2.1 mg/dL 明顯高於正常值，顯示腎功能受損，需評估補液計畫或改用其他影像檢查以降低風險。
Iodinated contrast dye is nephrotoxic and can precipitate contrast-induced nephropathy in clients with pre-existing renal impairment. A serum creatinine level of 2.1 mg/dL indicates significantly reduced kidney function, making this the critical value to report. The provider needs this information to assess the risk and potentially adjust hydration protocols or choose alternative imaging methods.
