Uremia is best defined as...

• A. Absence of urine formation
• B. Progressive loss of renal function
• C. Very high levels of protein lost in urine
• D. A toxic condition resulting from renal failure in which urea is retained in the blood

Answer: (D)

Uremia is a systemic toxic state that arises when kidney failure prevents clearance of waste products from the blood, especially urea. Normally, urea is filtered by the kidneys and excreted in urine; when renal function declines, urea and other nitrogenous wastes accumulate in the blood, producing a range of symptoms and organ dysfunction. This makes uremia fundamentally a toxic condition caused by retained urea due to kidney failure, rather than simply the absence of urine, the general process of progressing renal decline, or a feature like heavy protein loss in urine.
