Question 2
A 6-year-old boy on a well-balanced diet has marked edema of the legs, accumulation of fluid in the abdomen, and a low blood serum albumin and total serum protein. His urine contains large amounts of protein.
What is the most likely cause of edema? A. Increased capillary permeability allows excess fluid to leak from the capillaries.
B. Reduced serum albumin resulting from excess loss in the urine lowers plasma osmotic pressure, which allows excess fluid to leak from capillaries.
C. Low plasma proteins and albumin probably results from inadequate food intake, so the liver is unable to make sufficient albumin to maintain a normal plasma osmotic pressure.
D. Obstruction of lymphatic channels draining the lower part of the body forces fluid out of the capillaries into the tissues.
