Answer to Question 1

ANS: A
Embolism to the pulmonary circulation produces pulmonary hemorrhage in the ischemic area and infarction (or tissue death from deprivation of blood flow) in fewer than 10 of cases of pulmo-nary embolism. Infarction is less common than thromboembolism because the lung has two blood supplies: the pulmonary arterial circulation and the bronchial circulation.

Answer to Question 2

ANS: B
Pulmonary infarction is associated with thromboembolic obstruction of a medium-sized pulmo-nary artery and generally occurs at the lung bases where it usually presents as a wedge-shaped opacity on chest images.
