Answer to Question 1

ANS: C
A pneumothorax may be caused during the insertion procedure. An air embolism may be caused by the rupture of the balloon if overinflated or during insertion. A pulmonary infarction may be caused by the catheter being advanced into a smaller artery or by overinflation of the balloon, prolonged wedging, or clot formation. Ventricular fibrillation would most likely be caused during the insertion process when the endocardium is irritated by the catheter while it is passing through the heart.

Answer to Question 2

ANS: C
With spontaneous breathing, the intrapleural pressure decreases during inspiration, causing the pulmonary artery (PA) wave pattern to descend. Conversely, with spontaneous expiration, intra-pleural pressure increases, and the wave rises.
