一位腹部手術後的病人，護理師在術後評估時發現下列哪種徵象需立即通知外科醫師？
A nurse is performing a postoperative assessment for a client who had abdominal surgery. Which finding requires immediate notification to the surgeon?
- AAbdominal distention with absent bowel sounds 6 hours post-op腹部脹氣且術後6小時腸鳴音消失
- BLow-grade fever of 99.8°F攝氏37.1度（華氏99.8度）的低燒
- CSudden increase in heart rate and decrease in blood pressure✓ 正解心跳突然加快且血壓下降
- DSerosanguineous drainage on the surgical dressing手術敷料上有漿液血性滲出物
術後生命徵象改變如心跳增快、血壓下降，通常暗示體液流失、內出血或休克，為術後最危險的併發症。選項A為術後正常的腸阻塞恢復期，選項D為正常的傷口分泌物，選項B為常見的術後發炎反應，均可密切觀察，不需立刻通知醫師。
Postoperative changes in vital signs, such as tachycardia or falling blood pressure, often signal fluid loss, internal bleeding, or shock, and are the most dangerous postoperative complications. Option A represents the normal recovery period from postoperative ileus, option D represents normal wound drainage, and option B represents a common postoperative inflammatory response; all of these can be observed closely and do not require immediate notification of the physician.
台灣醫師較習慣護理師在發現生命徵象異常時立即回報；美國護理師常依據 SBAR 原則評估完整後再行報告。
