Verified step by step guidance1
Understand the definition of acute renal failure: Acute renal failure, also known as acute kidney injury, is a sudden loss of kidney function that occurs over a few hours or days.
Identify the common causes of acute renal failure: These can include conditions that reduce blood flow to the kidneys, damage the kidneys directly, or obstruct urine flow.
Evaluate dehydration as a cause: Dehydration can lead to reduced blood flow to the kidneys, which is a common cause of acute renal failure.
Consider urinary tract infection: While it can cause kidney issues, it is not typically a direct cause of acute renal failure unless it leads to severe complications.
Assess hypertension and diabetes mellitus: These are more commonly associated with chronic kidney disease rather than acute renal failure, as they cause long-term damage to the kidneys.
