Answer to Question 1

ANS: C
Symptoms of gram-negative septic shock are produced by endotoxins. Once in the blood, endo-toxins cause the release of vasoactive peptides and cytokines that affect blood vessels, producing vasodilation, which reduces blood pressure, causes decreased oxygen delivery, and produces subsequent cardiovascular shock. Gram-positive bacteria nor fungi do not produce endotoxins and thus do not manifest in shock. Viruses do not produce symptoms of shock.

Answer to Question 2

ANS: C
Virus replication depends totally on the ability of the virus to infect a permissive host cell, a cell that cannot resist viral invasion and replication. Viruses contain both DNA and RNA, are incapa-ble of independent reproduction, and cannot be killed by antimicrobials.
