Renal Diseases: The Daily PANCE Blueprint
A urine output of < 400 mL/day is defined as?
A. Anuria
B. Polyuria
C. Oliguria
D. Nocturia
E. Azotemia
Answer and topic summary
The answer is C. Oliguria
- Oliguria or hypouresis is the low output of urine, specifically > 80 ml/day but less than 400 ml/day. Oliguria is one of the first indicators of acute renal injury.
- Anuria is nonpassage of urine and represents a urine output of < 100 ml/day. Anuria is often caused by a failure in the function of the kidneys.
- It may also occur because of some severe obstruction, like kidney stones or tumors. It may occur with end-stage kidney disease. It is a more extreme reduction than oliguria, with 100 mL/day being the conventional (albeit slightly arbitrary) cutoff point between the two.
- Polyuria is an increase in the total volume of urine, usually > 3000 ml/day.
- Azotemia refers to elevated serum concentrations of blood urea nitrogen and creatinine
