Answer to Question 1

ANS: B
Pulmonary emboli arise from detached portions of venous thrombi that form, in most cases, in deep veins of the lower extremities or pelvis (86).

Answer to Question 2

ANS: A
Pulmonary embolism is more frequently observed in the lower lobes and more commonly in the right rather than in the left lung, a phenomenon related to the pulmonary flow distribution that tends to favor the right side and the lower lobes.
