對於低血容性休克的病人，哪項評估結果顯示液體復甦已見效？
Which assessment findings in a client with hypovolemic shock indicate that fluid resuscitation has been effective?
- AUrine output 35 mL/hr✓ 正解尿量 35 mL/hr
- BBlood pressure 90/60 mmHg血壓 90/60 mmHg
- CRespiratory rate 22 breaths/min呼吸頻率 22 次/分
- DHeart rate 110 beats/min心率 110 次/分

休克復甦成功的黃金標準是器官灌流改善。尿量恢復至每小時 30 mL 以上，代表腎臟獲得足夠的循環血量，是最具說服力的指標。選項 B 的血壓仍偏低；選項 D 的心跳仍過速；選項 C 的呼吸未完全平復，這些皆顯示休克仍未完全改善。
The gold standard for successful shock resuscitation is improvement in organ perfusion. Urine output returning to at least 30 mL/hr indicates that the kidneys are receiving adequate circulating volume and is the most reliable indicator. In option B the blood pressure remains low; in option D the heart rate remains elevated; in option C the respiratory rate is not fully normalized; all of these suggest that shock has not been fully reversed.
✦ 台美臨床差異
美國 ICU 常使用 CVP 或超音波評估容量，台灣臨床則更依賴動脈血壓與尿量監測。
