Which statement is true about frostnip and frostbite?

• A. Frostnip is the less advanced stage of frostbite.
• B. Frostbite is less severe than frostnip.
• C. Frostnip always causes necrosis.
• D. Frostbite never occurs on exposed skin.

Answer: (B)

Frostnip and frostbite represent a progression of cold injury, with frostnip being the milder, superficial form and frostbite being the more severe, deeper injury. Frostnip freezes only the surface of the skin, causing numbness and pale skin that typically reverses with warming and does not cause permanent tissue damage. Frostbite involves actual freezing of deeper tissues, can lead to blistering, and in more severe cases may cause necrosis and lasting tissue loss. Because deeper tissue injury and potential tissue death are features of frostbite, it is the more severe condition. Therefore, the true understanding is that frostnip is the less severe, earlier form and frostbite is the more severe form.
