Answer to Question 1

ANS: A
If the posterior hypothalamus senses that the body's temperature is lower than the set point, the body initiates heat conservation mechanisms. Vasoconstriction of blood vessels reduces blood flow to the skin and extremities. The anterior hypothalamus controls heat loss by inducing sweating, vasodilation of blood vessels, and inhibition of heat production.

Answer to Question 2

ANS:
B, D, F, A, E, C
The nurse manager is evaluating the chain of infection to determine actions that could be implemented to influence the spread of infection in the intensive care unit. Understanding the spread of infection and directing actions toward those steps have the potential to decrease infection in the setting. For spread of infection, the chain has to be uninterrupted with an infectious agent, a reservoir and portal of exit, a mode of transmission, a portal of entry, and a susceptible host.
