What is the term for an excess of urea and other nitrogenous wastes in the blood as a result of kidney insufficiency?

Uremia.
Anuria.
Oliguria.
The Correct Answer is B

Choice A is wrong because azotemia is the buildup of nitrogen waste products in the blood, not urea.

Choice D is wrong because oliguria is the low output of urine.
