Which injury is a superficial freezing injury?

• A. Frostnip
• B. Frostbite
• C. Hyperthermia
• D. Fever

Answer: (A)

Frostnip is the mild, superficial freezing injury that affects only the surface layers of the skin without causing tissue death. When skin is exposed to cold, it can freeze at the surface, leading to numbness, pallor, and a tingling or prickling sensation. Because the injury is limited to the epidermis/upper dermis, there is no permanent tissue damage, and warming the skin restores normal sensation quickly with proper care. Frostbite, in contrast, involves actual freezing of deeper tissues and can lead to tissue necrosis and blistering. Hyperthermia and fever are heat-related conditions, not freezing injuries.
