Which is a sign of mild/superficial frostbite?

• A. Increased sensation
• B. Rapid healing
• C. Vesicles are present
• D. Skin color white

Answer: (C)

In frostbite, how deep the tissue injury goes changes what you see. For mild or superficial frostbite, the damage is to the outer skin layers, and after rewarming you often get blister formation. Those vesicles—fluid-filled blisters—reflect that separation of skin layers has occurred and is characteristic of this shallow injury. Other signs aren’t as specific: increased sensation isn’t typical because freezing tends to dull sensation; rapid healing isn’t expected since the tissue needs time to recover and may blister; skin turning white can happen with frostbite but isn’t specific to the superficial level and can occur in other stages too. So the presence of vesicles is the best indicator of mild/superficial frostbite.
