Answer to Question 1

B, C, D, E
The infusion of cool IV fluids, inhalation of cool anesthetic gases, exposure of body surfaces, and lowered metabolism predispose patients to hypothermia during surgery. The operating room is kept cool to inhibit growth of organisms.

Answer to Question 2

C
The continuous passive motion (CPM) machine is used to provide movement to a joint in recov-ery. The apparatus is driven by a motor and requires no effort on the part of the patient or nurse to move the limb. It is usually left on all day and is discontinued at night while the patient sleeps. CPM is preset as to speed and the degree of flexion that is determined by the physician and should not be adjusted by the patient.
