What is the term for the harmful buildup of waste products in the bloodstream due to kidney failure?

• A. Uremia
• B. Azotemia
• C. Metabolic acidosis
• D. Edema

Answer: (A)

In kidney failure, filtration drops and waste products such as urea build up in the blood. When this accumulation produces symptoms and a clinical syndrome, it’s called uremia. This goes beyond a lab finding of waste in the blood and reflects the systemic effects the body experiences from the buildup, such as fatigue, nausea, and confusion in severe cases. Azotemia is related but refers to the elevated nitrogenous wastes in the blood as a lab finding, often without symptoms. Metabolic acidosis is a common consequence of kidney dysfunction due to the kidneys' reduced ability to excrete acid, and edema is fluid overload from impaired excretion—not the waste buildup itself.
