Answer to Question 1

D
Anaerobic bacteria are responsible for foul-smelling, brown or grey secretions associated with a lung abscess.

Answer to Question 2

D
An inferior vena cava vein filter may be surgically placed in the inferior vena cava to prevent clots from being carried into the pulmonary circulation. The effectiveness and safety of these filters are not well established and, in general, they are only recommended in some high-risk patients. Edema distal to the filters is a complicating factor.
