Question

which of the following is less likely to result in edema? multiple choice increased mean arterial pressure loss of protein molecules in urine through the kidneys blockage of veins reduced plasma colloid osmotic pressure increase in capillary permeability

Explanation:

Edema is fluid - accumulation in tissues. Increased mean arterial pressure can force more fluid out of capillaries into tissues, loss of protein in urine reduces plasma colloid osmotic pressure (which normally pulls fluid back into capillaries), blockage of veins causes blood - back up and increases capillary hydrostatic pressure leading to fluid leakage, and increased capillary permeability allows more fluid to leave capillaries. None of these are less likely to cause edema. However, among the options, there is no correct "less likely" cause as all typically contribute to edema development. But if we consider normal physiological scenarios, under normal conditions, a slight increase in mean arterial pressure might be more "tolerable" compared to the other drastic changes like significant protein loss, major vein blockage etc.

Answer:

A. Increased mean arterial pressure
