A shot of alcohol can warm a hypothermic patient

While alcohol does give you a sense of warmth, but dilates blood vessels which can increase heat loss. This can also cause changes in judgement and coordination. Instead, remove wet clothes and provide insulation. Warm the patient in a dry place. Add layers. Give warm, sweet fluids if the patient is responsive. Don’t let the patient sit, stand, or walk until they are warmed.

Rub frost bit vigorously

Frozen body parts require rapid rewarming in controlled environments. Remove anything that constricts the extremity like rings or bracelets. Separate fingers and toes with loose gauze. Do not pop any blisters. Elevate the area, insulate, and transport to advanced medical care.

Apply butter to treat a burn

Cool the area with sterile, cool water or saline. Cover with a cool wet dressing, but don’t leave it on for more than 10 minutes. Cover with a clean, sterile dressing. If you are trained in giving oxygen, administer oxygen to protect patient from heat loss. Transport to medical care.
