Answer to Question 2
A
There are times during brain or cardiac surgery that hypothermia is induced to lower the patient's metabolism so that less oxygen is needed by the body. If a patient has a high fever, measures are taken to lower it but not to the point of hypothermia. Carbon monoxide poisoning is not treated by hypothermia.
