Answer to Question 1

ANS: B
Results of more recent analysis tend to refute this explanation, instead showing that impaired re-nal function during positive-pressure ventilation is better associated with a decrease in intravas-cular volume.

Answer to Question 2

ANS: A
High ventilation pressure has long been associated with barotrauma.
