Which of these is safe to give to a person who may be suffering from hypothermia

Warm the person by wrapping him or her in blankets or putting dry clothing on the person. Do not immerse the person in warm water. Rapid warming can cause heart arrhythmia. If using hot water bottles or chemical hot packs, wrap them in cloth; don't apply them directly to the skin.

Answer: I would out them next to a campfire and give them something warm to drink like hot chocolate, and give them a blanket to cover themselfs up in, I mean it would be the right thing to do in my opinion.
