護理師正在評估一位剛接受經股動脈心導管檢查的病人。下列哪項發現需要立即處理？
A nurse is assessing a client after a cardiac catheterization via the femoral artery. Which finding requires immediate intervention?
- AThe client's blood pressure is 128/82 mmHg病人的血壓為 128/82 mmHg
- BThe client reports mild bruising at the insertion site病人報告穿刺部位有輕微瘀青
- CThe pedal pulse on the affected side is weaker than the unaffected side✓ 正解患側的足背脈搏比健側弱
- DThe client reports a warm sensation during the procedure病人報告在手術過程中有溫暖感
心導管術後肢體遠端脈搏減弱或消失可能代表血栓形成、動脈痙攣或出血壓迫，恐導致肢體缺血。輕微瘀青是常見的；術中熱感是造影劑的正常反應。血壓正常不需立即處理。護理師應評估 5P（脈搏、顏色、溫度、感覺、運動）。
After cardiac catheterization, a diminished or absent distal pulse may indicate thrombus formation, arterial spasm, or compression from hemorrhage, all of which can result in limb ischemia. Mild bruising is common; a warm sensation during the procedure is a normal response to contrast media. A blood pressure within normal limits does not require immediate action. The nurse should perform the 5 P assessment (pulse, pallor, temperature, paresthesia, paralysis).
美國護理師常使用床邊超音波（Doppler）評估難以觸摸的脈搏；台灣臨床也普遍使用，但更強調徒手感觸的準確性。
