護理師照護一位急性低血容性休克病人,下列哪項評估指標顯示液體復甦處置有效?
A nurse is caring for a client with acute hypovolemic shock. Which assessment finding indicates a positive response to fluid resuscitation?
- AUrine output of 40 mL/hour✓ 正解尿量 40 mL/小時
- BCapillary refill time of 5 seconds微血管充填時間 5 秒
- CHeart rate of 120 beats per minute心率 120 次/分鐘
- DRespiratory rate of 28 breaths per minute呼吸頻率 28 次/分鐘

休克復甦的黃金指標是器官灌流的恢復,尤其以腎臟功能最敏感。當尿量維持在 30-50 mL/hr 以上時,代表心輸出量與腎臟灌流已改善。其餘選項心搏過快、微血管填充時間延長與呼吸急促,均為休克未解除的病理表現。
A urine output of 40 mL/hour indicates adequate renal perfusion and a positive response to fluid resuscitation in hypovolemic shock. Other findings such as prolonged capillary refill, tachycardia, and tachypnea suggest ongoing shock and insufficient tissue perfusion.
✦ 台美臨床差異
台美臨床在休克評估上均以尿量為首要指標,但台灣護理師依醫囑給予液體速度較嚴謹,美國護理師常依據給定參數(如 MAP > 65)自行調整輸液速度。
