What is the most common cause of acute renal failure in Korea
Question : What is the most common cause of acute renal failure in Korea?
A. Diabetic nephropathy
B. Hypertensive nephropathy
C. Acute tubular necrosis (ATN)
D. Glomerulonephritis
Answer: C
Explanation: Acute tubular necrosis (ATN) caused by ischemia (e.g., hypovolemia, shock) or nephrotoxins (e.g., medications, contrast agents) is the most common cause of acute renal failure in Korea, accounting for about 40%-50% of cases. Diabetic nephropathy and hypertensive nephropathy are the main causes of chronic kidney disease; glomerulonephritis is a less common cause of acute renal failure. Therefore, the correct answer is C.
