Answer: The correct answer is keep the person warm.
Explanation:
Hypothermia is a great loss of heat in your body. It falls from the usual body temperature (98.6 F/37 C) to below 95 F/35C. When this happens, the nervous and the respiratory along with the heart gradually begin to fail.
The safest thing to do is, besides calling for help, keep the person warm. If you can, take him gently somewhere inside to a dry place. Remove his wet clothes slowly. It's advised not to rub him. Start placing layers of dry materials such as coats and blankets. If possible, cover the person's head. This will keep him warm.
