What should you do for a crew member who has suffered frostbite to the toes of both feet?

Correct Answer: Option A — immerse the feet in warm water

Rapid rewarming of frostbitten tissue is best achieved by immersing the affected body parts in circulating warm water maintained between 100°F and 108°F (38°C to 42°C). This standard medical practice prevents further cellular damage and restores normal microvascular circulation safely.
