Multiple Choice

A creatinine clearance of 0.32 mL/s corresponds to approximately how many mL/min?

Creatinine clearance is often given per minute, so convert from per second by multiplying by 60 (there are 60 seconds in a minute). 0.32 mL/s × 60 = 19.2 mL/min, which rounds to about 19 mL/min. This shows how a value expressed per second translates to per minute. In context, normal clearance is roughly 90–120 mL/min, so 19 mL/min indicates a much lower kidney function.
