What signs indicate frostbite in a person?

• A. Red and swollen skin
• B. White or grayish-yellow patches
• C. Blisters on the skin
• D. Itchiness and redness

Answer: (B)

The presence of white or grayish-yellow patches on the skin is a key indicator of frostbite. This discoloration occurs due to the freezing of skin and underlying tissues, resulting in a significant loss of blood flow. In the early stages of frostbite, the affected area may appear red and cold, but as the condition worsens, it can develop into the characteristic pale or grayish appearance.

Recognizing these signs is crucial for timely intervention, as frostbite can lead to permanent damage if not treated promptly. While other symptoms like blisters and redness may indicate different skin conditions or injuries, the distinctive pale or grayish-yellow patches specifically signal frostbite. Understanding this helps in differentiating frostbite from other skin injuries and ensures appropriate first aid measures are taken.
