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.

Chronic necrotizing aspergillosis has a slowly progressive process that, unlike invasive aspergillosis, does not spread to other organ systems or the blood vessels. It most often affects middle-aged and elderly individuals, spreading to surrounding tissue in the lungs. The disease often does not respond to conventionally successful treatments, and requires individualized therapies in order to keep it from becoming life-threatening.

Chronic marijuana use can damage the white blood cells and reduce the immune system's ability to respond to disease by as much as 40%. Without a strong immune system, the body is vulnerable to all kinds of degenerative and infectious diseases.
