What term describes elevated kidney values?

• A. Azotemia
• B. Cardiomegaly
• C. Cystocentesis
• D. Dyspnea

Answer: (A)

Azotemia describes elevated nitrogenous waste in the blood, typically shown by high BUN and creatinine, which signals reduced kidney filtration or function. This is why it’s the best term for elevated kidney values. It can arise from different mechanisms—pre-renal (often dehydration or low blood flow), renal (intrinsic kidney disease), or post-renal (urinary tract obstruction). The other terms refer to a heart enlargement (cardiomegaly), a procedure to obtain a urine sample (cystocentesis), and breathing difficulty (dyspnea), none of which describe increased kidney waste in the blood.
