一位心導管術後病人。哪項發現需要立即回報醫師？
A nurse is monitoring a client post-cardiac catheterization. Which finding requires immediate reporting to the provider?
- AWeak pedal pulse on the affected extremity✓ 正解患肢足背脈搏微弱
- BSlight bruising at the insertion site穿刺部位有輕微瘀青
- CStable vital signs生命徵象穩定
- DReports of minor discomfort at the groin腹股溝處有輕微不適感
心導管術後（Post-cardiac catheterization）的重點評估在於遠端血液灌流（Distal perfusion）。患側足背動脈（Pedal pulse）脈搏減弱或消失，暗示血管可能出現栓塞或嚴重出血，這是肢體缺血壞死的關鍵警訊。護理師必須將此視為緊急狀況，立即回報醫師進行處置，以防肢體永久性損害。其他選項如穩定生命徵象或輕微不適，均在預期範圍內。
The key assessment after cardiac catheterization is distal perfusion. A diminished or absent pedal pulse in the affected extremity suggests possible arterial occlusion or significant bleeding and is a critical warning sign of limb ischemia or potential necrosis. The nurse must treat this as an emergency and immediately notify the provider for intervention to prevent permanent limb damage. Other options, such as stable vital signs or minor discomfort, are within expected limits.
