1

Mechanism of fluid accumulation in heart failure

increase in hyrdrostatic pressure

2

Mechanism of fluid accumulation in nephrotic syndrome

decrease in oncotic pressure

increase vascular permeability

4

Mechanism of fluid accumulation post MRM

lymphatic obstruction

5

During chronic congestion, macrophages phagocytose RBCs leading to this cell type (hemosiderin-laden)

heart failure cells

white infarct

18

[Stage of shock]

presence of tachycardia with peripheral vasoconstriction and renal fluid vasoconstriction

cardiogenic

21

[type of shock]
decreased PCWP, increased CO, decreased SVR

distributive
