You Have Been Chosen by the Medical Director to Give

You have been chosen by the medical director to give a 15-minute presentation on cold-related emergencies to a local volunteer fire department. In preparing the talk, which one of the following points should you emphasize?

A) Emergency responders play a critical role in caring for the hypothermic patient since the most important phase of care occurs during the first 30 minutes.
B) Of the two types of cold-related injuries, a local cold injury, or frostbite, is more life-threatening since it can result in the loss of fingers, toes, arms, or legs.
C) Coma or unresponsiveness in the patient suffering a cold-related injury is actually protective since it decreases the body's energy requirements.
D) A cold-related emergency becomes critical when the body temperature falls below 79°F since at this point the body loses ability to regulate its temperature.
