What does the abbreviation ARF stand for?

• A. Acute Renal Failure
• B. Autonomic Renal Failure
• C. Acute Reproductive Failure
• D. Acute Respiratory Failure

Answer: (A)

ARF stands for Acute Renal Failure, a sudden drop in kidney function that impairs the kidneys’ ability to filter waste, regulate fluids, electrolytes, and acid-base balance. This abbreviation is commonly used in medical documentation and teaching to denote acute kidney injury. The other options aren’t standard expansions of ARF: Autonomic Renal Failure isn’t a recognized term, Acute Reproductive Failure isn’t a typical medical phrase, and while Acute Respiratory Failure is a valid concept, it’s not the usual meaning assigned to ARF in medical references.
