Frostbite progresses in which direction?

Frostbite progresses in which direction?

• A. From proximal to distal and deep to superficial
• B. From surface to inner only
• C. No progression
• D. From distal to proximal and superficial to deep

Answer: (D)

Frostbite damage begins in the most exposed outer tissues and then moves inward toward the body’s core. The freezing process first affects the distal parts—fingers, toes, ears, nose—and, as exposure continues, injury extends from the surface to deeper structures and toward the proximal direction (toward the body). Practically, this means frostbite progresses from distal to proximal and from superficial to deep. This pattern fits why frostbite can involve deeper tissues and move toward the trunk if the cold exposure persists, whereas a progression that is only surface-to-inner or that moves from proximal outward wouldn’t capture the typical spread of freezing injury.
