Answer to Question 1

ANS: B
Epoprostenol delivered by continuous intravenous infusion, improves exercise capacity, hemo-dynamic variables, and survival in IPAH patients and is the treatment of choice for severely ill patients.

Answer to Question 2

ANS: B
Supplemental oxygen should be used to maintain oxygen saturation greater than 90, especially because hypoxemia is a major cause of pulmonary vasoconstriction.
