Answer to Question 1

ANS: C
SVCS is a progressive occlusion of the superior vena cava that leads to venous distention in the upper extremities and head. Thromboembolism would not lead to the generalized symptoms de-scribed in the patient. Deep vein thrombosis would not lead to upper extremity symptoms. Chronic venous insufficiency would primarily affect one extremity.

Answer to Question 2

ANS: C
Cardiac output is found by the heart rate times stroke volume. Vascular resistance is not a factor in the calculation of cardiac output; it does play a role in blood pressure. Preload affects cardiac output but is not the result of heart rate times stroke volume. Ejection fraction is the amount ejected per beat.
