A patient admitted with sepsis has had several episodes of severe hypotension.Laboratory results indicate a BUN of 10.7 mmol/L (30 mg/dL),serum creatinine of 177 micromol/L (2.0 mg/dL),urine sodium of 70 mmol/L,urine specific gravity of 1.01,and cellular casts and debris in the urine.The nurse knows these findings are consistent with which condition?

The laboratory findings of elevated BUN and creatinine, along with the presence of cellular casts and debris in the urine, are consistent with acute tubular necrosis (ATN). The low urine specific gravity and high urine sodium also support a diagnosis of ATN. Prerenal failure would typically be characterized by a high urine specific gravity and low urine sodium, while post-renal failure may present with obstruction and a high urine specific gravity but would not typically cause elevated BUN and creatinine. Uremia is a broad term for the symptoms and complications associated with renal failure and is not a specific diagnosis.
