Azotemia is commonly found in which condition?

• A. Kidney infection
• B. Liver failure
• C. Ruptured or blocked bladder
• D. Heart disease

Answer: (C)

Azotemia means elevated nitrogenous wastes (like urea and creatinine) in the blood because the kidneys aren’t able to excrete them properly. When urine outflow is blocked, as with a ruptured or obstructed bladder, waste products build up in the bloodstream because urine can’t be eliminated effectively. In bladder blockage, the obstructed flow causes post-renal azotemia, and if the bladder ruptures and urine leaks into the abdomen, wastes can be reabsorbed from the peritoneal cavity, further raising blood levels. This makes bladder issues a classic scenario for azotemia.

Other conditions listed can affect the kidneys or circulation and may cause azotemia in different contexts, but a bladder blockage or rupture directly exemplifies the post-renal type of azotemia.
