B. Urine output of 30 to 60 mL/hr.
C. Urine output of less than 400 to 600 mL in 24 hours.
D. Urine output directly related to the amount of IV fluids infused.
参考答案：C
解析：
The three phases of acute renal failure are the oliguria phase (less than 400 to 600 mL of urine produced in 24 hours), diuresis, and recovery. The kidneys aren’t in a state of suppression, the average output isn’t 30 to 60 mL/hr, and the amount of output isn’t related to IV fluids infused.
