Progressive loss of renal function caused by conditions such as kidney disease, diabetes mellitus, and hypertension.

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

Answer: (B)

Progressive loss of renal function describes ongoing kidney damage that slowly worsens over time, which is the hallmark of chronic kidney disease progressing toward chronic renal failure. Long-standing diabetes and hypertension injure nephrons, lowering the glomerular filtration rate (GFR) gradually and allowing waste build-up and fluid/electrolyte imbalance to develop. This slow, irreversible decline fits chronic renal failure best.

Nephrotic syndrome centers on heavy protein loss in the urine with hypoalbuminemia, hyperlipidemia, and edema, but it’s a pattern of illness rather than a description of gradual kidney function decline. Anuria means very little or no urine output, a severe symptom that can occur in acute or chronic settings but doesn’t define the ongoing loss of function itself. Edema can accompany CKD, but it’s a common sign rather than the diagnosis.

So the statement aligns with chronic renal failure.
