Answer to Question 1

ANS: C
Patients with IPAH who respond to vasodilators in the short term have improved survival with long-term use of calcium-channel blockers. Thus, these agents should be considered in all patients who have significant and definite response to a short-acting vasodilator. Unfortunately, only a small fraction of IPAH patients qualify for and benefit from long-term therapy with oral calci-um-channel blockers.

Answer to Question 2

ANS: B
Single or double lung transplantation has been used successfully in the treatment of patients with IPAH. Lung transplantation is indicated in the care of patients who do not respond to vasodila-tors and have significant cardiac impairment.
