Increased serous fluid can be caused by all of the following except:
A) Lymphatic obstruction
B) Inflammation
C) Increased plasma sodium
D) Increased hydrostatic pressure

Question

Quizplus · Accepted Answer

Increased plasma sodium would actually cause a decrease in serous fluid, as the osmotic pressure gradient would draw fluid out of the serous cavity and into the blood. A, B, and D can all lead to an increase in serous fluid, as lymphatic obstruction can prevent drainage of fluid, inflammation can increase capillary permeability and therefore fluid leakage, and increased hydrostatic pressure can push fluid out of blood vessels and into tissues.
