A definition of uremia is

A definition of uremia is

• A. An increase of wastes in the blood
• B. A decrease of wastes in the blood
• C. Inflammation of the kidneys
• D. Normal kidney function

Answer: (A)

Uremia means wastes that should be removed by the kidneys have built up in the blood because the kidneys aren’t filtering properly. This buildup reflects impaired renal clearance of nitrogenous wastes like urea and other toxins. That’s why the correct definition is an increase of wastes in the blood—signaling that filtration is not functioning adequately. The other statements describe situations that don’t fit uremia. A decrease of wastes would indicate better clearance, not uremia. Inflammation of the kidneys refers to nephritis, a different process. Normal kidney function would not produce waste buildup at all.
