Final answer:
The correct urine output for children is 1 to 2 mL/kg/h, which is higher than that for adults due to the different metabolic and kidney function in children.
Step-by-step explanation:
The appropriate urine output in adults is 0.5 to 1 mL/kg/h and 1 to 2 mL/kg/h in children. This is because children's metabolism and kidney function are different from adults, resulting in a higher normal range of urine output. The kidneys must produce a minimum urine volume of about 500 mL/day to rid the body of wastes. Output below this level is known as oliguria and may indicate severe dehydration or renal disease, whereas the complete absence of urine is termed anuria. On the other hand, excessive urine production, or polyuria, can be observed in conditions like diabetes mellitus or diabetes insipidus.
