Answer to Question 1

ANS: A
The ejection fraction is a way of estimating the force that the ventricle generates during each car-diac cycle. It is calculated as the ratio of the stroke volume to the ventricular end-diastolic vol-ume. Systemic vascular resistance is used to describe the afterload that the left ventricle must overcome to eject blood into the systemic circulation. The pulmonary vascular resistance reflects the afterload that the right ventricle must overcome to eject blood into the pulmonary circulation. The right ventricular end-diastolic pressure is used as an indicator of the right ventricular preload and the left ventricular end-diastolic pressure is used to indicate left ventricular preload.

Answer to Question 2

ANS: B
The systemic vascular resistance is the resistance the left ventricle must contract against to eject blood into the systemic circulation. Ejection fraction is a measurement of contractility. Pulmonary vascular resistance is the resistance the right ventricle must contract against to eject blood into the pulmonary circulation. Left ventricle end-diastolic pressure (LVEDP) is used to estimate left ventricular preload.
