Which symptom is indicative of frostbite?

Pale or cold skin is indicative of frostbite because this condition occurs when skin and underlying tissues freeze due to exposure to extremely cold temperatures. As the skin cools, blood flow is reduced, leading to a pale appearance as the normal reddish hue of healthy skin is lost. Cold skin is another characteristic symptom, as the tissues are unable to maintain warmth in frigid conditions.

In contrast, the other symptoms listed do not correlate with frostbite. Dizziness may indicate dehydration or hypothermia rather than frostbite directly. A high fever usually points to infection or illness, while persistent sweating can be associated with heat-related conditions, not cold exposure. Therefore, recognizing pale or cold skin as a symptom is crucial for identifying frostbite and taking appropriate action.
