The document contains 16 multiple choice questions testing knowledge of hemodynamic and thrombosis related topics. The questions cover causes of edema, sites of thrombosis formation, mechanisms of pulmonary embolism and congestive heart failure edema, characteristics of venous thrombosis and infarction, and definitions relating to thrombosis pathology. Key areas addressed include causes of generalized edema, predisposing factors for thrombosis, mechanisms of edema in heart failure, common sites of thrombus origin and venous thrombosis.
