Question

Calculate renal clearance of X given the following information: GFR = 100 mL/min, urine flow rate = 5 mL/min, plasma concentration of X = 10 mg/mL, urine concentration of X = 50 mg/mL.

1) 50 mg/min
2) 25 mg/min
3) 4 mg/min
4) 50 mL/min
5) 25 mL/min

Answer 1

The renal clearance of X is 25 mg/min

Step-by-step explanation:

The renal clearance of X can be calculated using the formula:

Renal Clearance = (Urine Concentration of X * Urine Flow Rate) / Plasma Concentration of X

Plugging in the given values: Renal Clearance = (50 mg/mL * 5 mL/min) / 10 mg/mL = 25 mg/min.
