Which laboratory finding is commonly associated with renal azotemia in cats?

Explanation:
Renal azotemia occurs when the kidney’s filtering ability declines, and the tubules lose their capacity to concentrate urine. As a result, even though waste products like urea and creatinine rise in the blood (azotemia), the urine remains isosthenuric, with a specific gravity roughly equal to plasma (about 1.008–1.012). This combination—azotemia with isosthenuria—is a classic lab finding in cats with renal azotemia. The other options don’t reflect this concentrating defect. Hypoglycemia or hyperglycemia aren’t characteristic features of renal azotemia, and hypernatremia without azotemia would suggest a different process, such as dehydration with relatively preserved renal function.
