Q

True about pulmonary edema

a. mechanism depends on balance of hydrostatic and oncotic forces in the capillaries surrounding tissue.
b. hydrostatic pressure favors fluid movement into the vessel
c. oncotic pressure favors fluid movement from capillary to interstitium
d. hypoalbuminemia can cause interstitial edema by itself

A

A.

oncotic: fluid movement into the vessel; hydrostatic: into interstitium
