病人預計接受需要對比劑（顯影劑）的診斷檢查，護理師應優先評估哪項實驗室數據以預防腎損傷？
A client is scheduled for a diagnostic procedure requiring contrast dye. Which laboratory result should the nurse prioritize to prevent kidney injury?
- ASerum potassium血清鉀
- BSerum albumin血清白蛋白
- CHemoglobin level血紅素濃度
- DCreatinine clearance✓ 正解肌酸酐清除率
— Explanation · 中文詳解 —
顯影劑具腎毒性，透過腎絲球過濾系統排泄，因此腎功能指標是檢查前的關鍵評估。肌酸酐清除率（CrCl）能精確反映腎功能狀況，協助醫療團隊決定是否需在檢查前後執行補液計畫或預防性藥物給予，以降低顯影劑誘發性腎病變（CIN）的發生。
Contrast dye is nephrotoxic and is excreted through glomerular filtration, so renal function indicators are a key pre-procedure assessment. Creatinine clearance (CrCl) accurately reflects renal function and helps the medical team decide whether to implement a pre- and post-procedure hydration plan or prophylactic medication to reduce the risk of contrast-induced nephropathy (CIN).
✦ 台美臨床差異
美國放射科與腎臟科合作密切，護理師在造影前有權直接依常規暫停檢查，台灣多由醫師判讀後決定是否執行。
