In scope icon M 1 A
QID 215068 (Type "215068" in App Search)
A researcher is testing a potential new therapy for heart failure that may affect the filtration fraction. To determine this, patient A was given an intravenous infusion of inulin and para-aminohippuric acid (PAH). Urinary specimens and blood plasma were then collected at regular intervals. The inulin clearance was calculated to be 63 mL/min. The remaining lab values are as follows:

Hematocrit: 45%
Plasma concentration of PAH: 0.15 mg/ml
Urine concentration of PAH: 60 mg/ml
Urine flow rate: 1 ml/min

Which of the following represents the correct filtration fraction for patient A?
