AUrine output above 2.5 L a day
BUrine output of 50 mL or less a day
CUrine output of 1 to 2 L a day
DUrine output of about 500 mL a day
Answer & Solution
Correct answer: B. Urine output of 50 mL or less a day
1. Anuria means the virtual absence of urine production.
2. The figure attached to it is 50 mL or less per day.
3. One to two liters a day is the normal range, and above 2.5 liters is polyuria.
4. About 500 mL a day is the minimum needed to clear wastes, which is far above the anuric range.
