Answer to Question 1

ANS: D
The chest radiographic findings include enlargement of the main and hilar pulmonary arteries, pruning (or narrowing) of the peripheral arteries, and enlargement of the right ventricle and atrium though the chest radiograph may remain normal in 6 of patients. Pleural effusions are not present.

Answer to Question 2

ANS: C
Physical findings associated with idiopathic pulmonary artery hypertension (IPAH) include a loud second heart sound and a right-sided third or fourth heart sound. Other common signs are a palpable right ventricular heave and impulse of the pulmonary artery and both pulmonary ejection and pulmonary tricuspid regurgitation murmurs. Signs of right ventricular failure are common. Cyanosis often is present as a result of low cardiac output or the presence of an intracardiac right-to-left shunt that occurs as cor pulmonale develops. Clubbing does not occur in IPAH.
