A sudden onset condition characterized by uremia that can be fatal if not reversed promptly.

• A. Acute renal failure
• B. Chronic renal failure
• C. Nephrotic syndrome
• D. Anuria

Answer: (A)

A sudden decline in kidney function leads to rapid buildup of nitrogenous wastes like urea, producing uremia. This abrupt change is the hallmark of acute renal failure, a condition that can become fatal if the underlying cause isn’t identified and treated quickly. The kidneys fail to filter waste, balance electrolytes, and manage fluids, so prompt reversal or supportive care (and sometimes dialysis) is crucial to prevent dire complications. Chronic renal failure, in contrast, develops over months to years with a gradual loss of function, so it isn’t described as a sudden onset. Nephrotic syndrome centers on heavy protein loss in the urine, edema, and low albumin, not primarily on uremia. Anuria means no urine production and can occur in severe kidney injury, but it is a sign or consequence within acute renal failure rather than the defining condition itself.
