Correct answer: B — Rewarm the fingers in warm water at around 37 to 39 degrees Celsius

Frostbite is best treated by rapid rewarming in warm water at about 37 to 39 degrees Celsius once there is no risk of refreezing, with analgesia, as rewarming is painful. Rubbing with snow, and dry or direct flame heat, cause further tissue damage. Refreezing a thawed part is especially harmful, so rewarming is undertaken only when this can be avoided. Pearl: do not thaw frostbite if there is any chance of refreezing before reaching definitive care.
