Answer to Question 1

ANS: C
Repeated opening and closing of lung units, also called recruitment/derecruitment, generates shear stress, which results in direct tissue injury at the alveolar and pulmonary capillary level. Barotrauma is lung injury caused by high pressure. Biotrauma refers to the release of inflamma-tory chemical mediators that cause multiorgan failure. Overdistention is the cause of biotrauma.

Answer to Question 2

ANS: B
High distending volumes result in overdistention of the alveoli, leading to the release of inflam-matory mediators from the lungs, which can result in multiorgan failure. The release of these in-flammatory mediators is called biotrauma.
