（CEB|SHL Talent Measurement） When your body is exposed to cold weather, it is important to be familiar with what can happen when precautions are not taken to keep warm. The stages someone experiences with frostbite closely resemble the stages of a burn. The characteristics of frostbite can indicate the stage of the condition: frostnip, superficial frostbite, and deep frostbite. The first stage of frostbite is called frostnip. It is an early condition of frostbite and is not technically even considered frostbite. It is usually found in different places on the head (nose, ears, cheeks) and can be characterised by a white, waxy-looking patch of skin. This patch of skin will eventually become red in colour and the person will experience pain or discomfort. Some relate it to a burning sensation and it may lead to blistering. Frostnip usually occurs in extreme cold temperatures where there is a significant wind chill and may only take a few minutes of exposure to set in. If you suspect frostnip, warm the affected area immediately (put fingers under warm water or even in a warm part of the body such as armpits). If this is caught early on, you can expect full recovery. The second stage is called superficial frostbite. At this stage, the skin will appear stark white and bloodless but will still be soft to the touch. The white colour indicates that the tissue under the skin has started to freeze. After I to 2 days of exposure, you will start to see large blisters appear, which will eventually become a dense, black scar called eschar. Once the frostbite reaches this stage, it usually takes a few weeks before the eschar is replaced by new skin. The final stage is called deep frostbite and is considered a serious (and rare) condition requiring immediate medical attention. The skin will turn a deep red or purple colour because the tissue underneath will be completely frozen. In addition, the skin will be cold to the touch and the person will lose feeling in the affected area. This condition leads to deep tissue damage and could result in amputation. Referring to the above, which one of the following is a result of deep frostbite?
