Question

analgesic nephropathy, a condition associated with excessive chronic use of aspirin and acetaminophen, usually present with microscopic features of:
pyelonephritis
membranoproliferative disease
papillary necrosis/interstitial fibrosis
glomerulonephritis
arterionephrosclerosis

Explanation:

Analgesic nephropathy, due to chronic excessive use of analgesics like aspirin and acetaminophen, is known to cause papillary necrosis and interstitial fibrosis in the kidneys. Pyelonephritis is an infection, membranoproliferative disease and glomerulonephritis are glomerular disorders, and arterionephrosclerosis is related to vascular changes, none of which are the typical microscopic features of analgesic nephropathy.

Answer:

C. Papillary necrosis/Interstitial fibrosis
