Answer 1 is incorrect because in early septic shock there is actually an increase in cardiac output. Answer 2 is correct because circulating blood volume would be decreased with GI bleeding. Answer 3 is correct because the ventricles are unable to pump the blood efficiently through the heart, so that cardiac output is decreased. Answer 4 is correct because positive end-expiratory pressure (PEEP) increases the intrathoracic pressure; therefore, venous return and cardiac output would be decreased. Answer 5 is incorrect because aerobic exercise increases the heart rate and thus cardiac output. Answer 6 is correct because damage to the myocardium decreases the pumping effectiveness of the heart and impacts cardiac output.
