Answer to Question 1

ANS: B
The pressure tracing from a right heart catheterization will first show the right atrial pressure tracing, followed by the right ventricle.

Answer to Question 2

ANS: C
Pulmonary artery wedge pressure, or pulmonary artery occlusion pressure, is used as an estimate of left atrial pressure and thus preload of the left ventricle, or left-ventricular end-diastolic pres-sure.
