Answer to Question 1

ANS: B
Exogenous pyrogens are endotoxins produced by pathogens. They are not interleukins, prosta-glandins, or corticotropin-releasing factors.

Answer to Question 2

ANS: D
Fever (febrile response) is a temporary resetting of the hypothalamic thermostat to a higher lev-el in response to endogenous or exogenous pyrogens. Fever is the result of the body's attempt to raise temperature, not adjust it to a lower level. When fever occurs, the temperature is raised, but the rise is due to a reset of the thermostat. Bacteria do not stimulate peripheral thermogenesis, but their endotoxins do.
