Which statement describes frostbite as opposed to frostnip?

• A. Frostbite involves actual freezing of tissue with ice crystal formation
• B. Frostnip involves tissue freezing with ice crystals
• C. Frostbite only affects superficial epidermis
• D. Frostnip causes necrosis

Answer: (B)

The main idea is that frostbite and frostnip differ by whether tissue actually freezes. Frostbite is a true freezing injury in which tissue freezes and ice crystals form inside cells and in the interstitial space. Those ice crystals damage cell membranes and disrupt microcirculation, which can lead to tissue death and even necrosis if severe or untreated. Frostnip, by contrast, is a superficial cold injury where the skin cools but tissue freezing does not occur, so there are no ice crystals in the tissue and warming reverses the symptoms without lasting damage. So the accurate statement describing frostbite is that it involves actual freezing of tissue with ice crystal formation, distinguishing it from frostnip.
