Which of the following conditions are considered intrarenal causes of acute kidney injury?

Intrarenal causes of acute kidney injury refer to kidney damage that occurs within the renal tissue itself, affecting the nephron's ability to function properly. Glomerulonephritis is considered an intrarenal cause because it involves the inflammation and damage of the glomeruli, which are crucial for filtering blood in the kidneys. This condition can lead to impaired kidney function and is a direct cause of acute kidney injury due to the damage sustained in the filtering structures of the kidney.

Conditions such as hypertension and dehydration, while they can impact kidney function, do not inherently damage the kidney tissue directly. Hypertension might lead to chronic issues over time, but it doesn't constitute an acute injury mechanism on its own. Dehydration can lead to prerenal causes of acute kidney injury by reducing blood flow to the kidneys rather than causing direct injury to the kidney tissue itself. Systemic lupus erythematosus, although it can indirectly lead to kidney problems, does so through systemic effects rather than direct renal tissue damage, making it less relevant as an intrarenal cause. Thus, glomerulonephritis stands out as the condition that directly causes damage within the kidneys, confirming it as the correct choice.
