  a. he developed pneumonia.
  b. his sympathetic nervous system has been damaged.
  c. he has a brain injury.
  d. he has septicemia from an unknown source.

ANS: B
The patient experiences disturbed thermal control because the sympathetic nervous system is damaged. The hypothalamus cannot regulate body heat through vasoconstriction and increased metabolism; therefore, the individual assumes the temperature of the air. In this situation there is no evidence to support the presence of pneumonia, brain injury, or septicemia.
