Answer to Question 1

ANS: A
IPAH can be life threatening and carries a poor prognosis. Without therapy, only 33 of patients are alive 5 years after the onset of the disorder.

Answer to Question 2

ANS: A
Pulmonary function tests are useful to rule out the presence of significant restrictive or obstruc-tive airway disease. The most common abnormality at pulmonary function testing of patients with IPAH is a low carbon monoxide diffusing capacity (DLCO).
