Neco 2019 Biology Question 44
Practice objective / multiple choice question 44 from the 2019 Neco Biology examination.
A subject's plasma creatinine concentration is 0.9 mg dL-1, urine creatinine concentration is 120 mg dL-1 and urine flow rate is 1.2 mL min-1. Calculate the creatinine clearance in mL min-1. In the same subject, plasma PAH concentration is 0.02 mg mL-1, urine PAH concentration is 12 mg mL-1 and urine flow rate remains 1.2 mL min-1. Assuming the extraction ratio for PAH is 0.9 and that PAH clearance equals the effective renal plasma flow, estimate the true renal plasma flow (RPF) in mL min-1.
