Question

BG is an 95 y/o male who is being treated for a UTI. He is 5’

5’’ and weighs 98lbs. His SCr is 0.6mg/dL. He has been prescribed
sulfamethoxazole/trimethoprim to treat the UTI. Calculate BG’s C

Answer 1

BG's creatinine clearance can be calculated using the Cockcroft-Gault equation. In this case, the calculation results in an approximate value of 16333.33 mL/min.

Step-by-step explanation:

BG’s Creatinine Clearance Calculation:

BG's creatinine clearance (C) can be calculated using the Cockcroft-Gault equation:

C = [(140 - Age) x Weight] ÷ Serum Creatinine x (0.85 for females)

Given that BG is a 95-year-old male weighing 98lbs and with a serum creatinine level of 0.6mg/dL, we can substitute these values into the equation:

C = [(140 - 95) x 98] ÷ 0.6 = 9800 ÷ 0.6 = 16333.33 mL/min.

BG's creatinine clearance is approximately 16333.33 mL/min.
