  a. Bosentan

Question 2

Why is the use of oxygen to maintain oxygen saturations greater than 90 particularly important in the management of idiopathic pulmonary artery hypertension?
 
  a. These patients have a low cardiopulmo-nary reserve.
  b. Low alveolar oxygen causes vasocon-striction.

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.
