All of the following decrease in the glomerular filtration rate except
Decreased plasma protein levels
Increased tubular hydrostatic pressure
Decreased effective filtration surface area
Decreased capillary hydrostatic pressure
Decreased plasma protein levels decrease plasma osmotic pressure and increase plasma hydrostatic pressure, hence GFR increases Ref: Ganong's review of medical physiology; 24th edition; page no; 680
