19. A 22-year-old woman is participating in a study that measures renal function. Evaluation of serum and urine shows the following:

Serum Urine
Na+ (mEq/L) 140 100
K+ (mEq/L) 4 50
Glucose (mg/dL) 100 0
Creatinine (mg/dL) 1 100
p-Aminohippuric acid (mg/mL) 0.1 50

Assuming a urine flow of 1 mL/min, which of the following best represents her filtration fraction?

A) .10
B) .20 ***
C) .30
D) .40
E) .50

FF=GFR/RPF
GFR= 1x 100/1=100
RPF=50x1/0.1=500
FF=100/500=.2

where you et thos e100 an d50 ????

[ArchivalUser]

for GFR=urine flow x Urine concentration of creatine/ plasma concentration of creatine
for RPF= urine flow x unrine concetration of PAH /Plasma concentration of PAH
