Which of the following best describes frostbite signs?

• A. Red, inflamed skin
• B. Blistering on thermal burns
• C. White or gray skin, numbness, hard tissue
• D. Itchy, warm patches

Answer: (C)

Frostbite signs show tissue freezing from cold exposure. The defining indicators are skin that is white or gray and waxy, along with numbness from nerve disruption, and a feel of hard, frozen tissue to the touch. This combination is what sets frostbite apart from other cold-related or skin injuries, which might present with redness and inflammation (more like irritation or sunburn), or with warmth and itching rather than numbness. In the field, recognizing pale, numb, and hard-feeling skin points to frostbite and signals the need for gentle warming and medical attention if needed.
