A 56-year-old man was admitted to the hospital with a myocardial infarction. At admission, his serum creatinine was 1.2 mg/dL, and his creatinine clearance was 100 mL/min

Over the next 3 days, he had several periods of hypotension, and his serum creatinine is now increased to 3.6 mg/dL. Assuming that he is in steady-state balance for creatinine (i.e., amount excreted = amounted produced), what is his predicted creatinine clearance?

A. 10 mL/min
B. 33 mL/min
C. 50 mL/min
D. 66 mL/min
E. 100 mL/min
