病人即將進行含有顯影劑的診斷檢查，哪項護理干預對於預防腎毒性至關重要？
A client is scheduled for a diagnostic procedure involving intravenous contrast dye. Which nursing intervention is essential to prevent nephrotoxicity?
- ARestrict dietary protein post-procedure術後限制飲食蛋白質攝取
- BEncourage increased fluid intake✓ 正解鼓勵增加液體攝取
- CAdminister a diuretic prior to the procedure在檢查前給予利尿劑
- DKeep the client NPO for 12 hours讓病人禁食 12 小時
顯影劑（Contrast dye）具有潛在的腎毒性（Nephrotoxicity），特別是對於腎功能已有損傷的病人，容易引起顯影劑誘發之腎病變（CIN）。預防的核心機轉是維持充足的腎臟血流灌注，加速顯影劑的代謝與排出。在檢查前後鼓勵病人攝取大量水分，能有效稀釋顯影劑並促進排泄，是減少腎毒性最簡單且有效的護理介入。
Contrast dye carries a potential risk of nephrotoxicity, particularly in clients with pre-existing renal impairment, who may develop contrast-induced nephropathy (CIN). The central mechanism of prevention is to maintain adequate renal blood flow to accelerate the metabolism and excretion of the contrast medium. Encouraging the client to drink ample fluids before and after the procedure effectively dilutes the contrast and promotes its excretion, making it the simplest and most effective nursing intervention to reduce nephrotoxicity.
