Answer to Question 1

ANS: D
To prevent hypothermia in the OR environment, place a hypothermia/hyperthermia mattress or reflective blanket on the operating bed. A radiant heat source can be placed over an infant. Check the room temperature and humidity. Apply warmed blankets as soon as the patient arrives in the OR and immediately after drapes are removed. A warm blanket can be put on the OR cart under the patient. Limit skin exposure during positioning and skin preparation (i.e., keep the patient covered as much as possible). Minimize the time of exposure between skin antisepsis and draping. Keep the sheet under and the drapes over the patient and around the surgical site dry to provide insulation, prevent heat loss, and maintain asepsis. Dry the area after skin preparation. Apply warmed antiseptic, irrigating, and IV solutions, including blood, before administration. Anesthetic gases, including oxygen, can be warmed also. Monitor body temperature. Leave a cap on the patient; a plastic head covering retains more heat than do other materials.

Answer to Question 2

ANS: B
The recommended dose is 2 to 3 mg/kg in an initial IV bolus and repeat every 5 to 10 minutes until the maximum dose of 10 mg/kg is given or the MH episode is controlled.
