Use the Values below to answer the following question:
HPGC = 49 mm Hg ?GC = 20 mm Hg Kf = 5 ml/min/mmHg
HPBS = 11 mm Hg ?BS = 0 mm Hg RBF = 720 ml/min
HCT = 50%
• HP = hydrostatic pressure
• ? = oncotic pressure
• GC = glomerular capillary
• BS = Bowman's space
• Kf = coefficient of filtration
• RBF = renal blood flow
• HCT = hematocrit
Using the data given above, which of the following might occur during
subsequent administration of an angiotensin II receptor antagonist?
Filtration fraction = 20%
GFR = 75 ml/min
RBF = 500 ml/min
Correct
Answer:
Filtration fraction = 20%
HPBS = 10 mmHg
Kf = 4 ml/min/mmHg
