The nurse is assessing a client with a diagnosis of prerenal acute kidney injury (AKI). Which condition would the nurse expect to find in the patient's recent history?

Rationale: A. Pyelonephritis is an infection of the renal pelvis and kidney tissue, which leads to intrarenal (not prerenal) damage due to inflammation and infection within the kidneys. B. Kidney stones obstruct urine flow and cause postrenal AKI, not prerenal. This type of injury occurs after the urine leaves the kidneys, leading to back pressure and impaired excretion. C. Dehydration leads to reduced blood flow to the kidneys, decreasing glomerular filtration rate (GFR) and causing prerenal AKI. Prerenal injury results from conditions that impair perfusion, such as hypovolemia, hemorrhage, or hypotension. D. Bladder cancer can cause postrenal AKI by obstructing the urinary outflow tract, but it does not affect renal perfusion directly, so it is not a prerenal cause.
