If GFR suddenly decreases from 150 ml/min to 75 ml/min and tubular fluid reabsorption simultaneously decreases from 149 ml/min to 75 ml/min, which of the following changes will occur (assuming that the changes in GFR and tubular fluid reabsorption are maintained)?

Given the following measurements, calculate the filtration fraction: glomerular capillary hydrostatic pressure = 50 mm Hg; Bowman’s space hydrostatic pressure = 15 mm Hg; colloid osmotic

pressure in the glomerular capillaries = 30 mm Hg; glomerular capillary filtration coefficient (Kf) = 12 ml/min/mm Hg; and renal plasma flow = 400 ml/min.
