Which term describes the presence of urinary waste products in the blood?

• A. Nocturia
• B. Copay
• C. Uremia
• D. Pyuria

Answer: (C)

Uremia describes the buildup of urinary waste products in the blood caused by kidney dysfunction. When the kidneys aren’t filtering properly, waste like urea and other nitrogenous compounds accumulate in the bloodstream, producing this condition. It reflects a systemic issue with renal clearance, not just a symptom in the urine.

Nocturia, the need to urinate during the night, relates to urination timing rather than waste accumulation in the blood. Pyuria refers to pus or white blood cells in urine, usually indicating infection, not systemic waste buildup. Copay is simply a cost-sharing term and has no relation to kidney function or waste in the blood.
