一位嚴重燒傷病人正接受靜脈輸液復甦。哪項發現提示液體容量足夠？
A client with severe burns is receiving intravenous fluid resuscitation. Which finding suggests that the fluid volume is adequate?
- AIncreased heart rate心率增加
- BDecreased urine output尿量減少
- CDecreased respiratory rate呼吸頻率降低
- DAdequate urine output and normal blood pressure✓ 正解充足的尿量與正常的血壓

嚴重燒傷病人因血管通透性增加，會迅速丟失血管內液體。有效的液體復甦（Fluid Resuscitation）目標是維持足夠的器官灌流。尿量是評估腎臟灌流最靈敏的指標，通常維持在每小時 0.5-1 mL/kg（或 >30 mL/hr）代表液體補給充足。結合正常的血壓，顯示循環容積已達到穩定狀態，能有效預防燒傷引起的休克與急性腎衰竭。
Adequate fluid resuscitation is best indicated by stable vital signs, specifically normal blood pressure and sufficient urine output, which reflects effective renal perfusion. Other options such as increased heart rate or decreased urine output suggest ongoing hypovolemia or inadequate fluid replacement rather than successful resuscitation.
