Use this same scenario for this question A 40-year old man is admitted to the hospital with acute renal failure after exposure to a toxic chemical spill at his workplace.  At his last yearly check-up, he was 70 kg, his blood analysis and urinalysis were unremarkable and his GFR was estimated to be 120 mL/min with a creatinine of 1 mg/dL.  Upon admission to the hospital, his plasma creatinine was 2 mg/dl.  Over the following week, his plasma creatinine rose to 4mg% and then came down to 3mg% and stabilized at 3 mg%.  How is the acute renal failure in this man best classified?
