Answer to Question 1

ANS: C
These investigators demonstrated that ARDS, regardless of the cause, is associated with an in-flux of neutrophils (PMNs) and PMN-derived inflammatory byproducts, such as neutrophil elas-tase and myeloperoxidase, into the lung.

Answer to Question 2

ANS: A
Although many seemingly unrelated risk factors for ARDS have been identified, all causes of ARDS evoke disruption of endothelial and epithelial barriers and typically occur under condi-tions associated with widespread microvascular injury to the lungs.
