A systemic cold emergency affecting the entire body is known as

• A. Frostnip
• B. Hypothermia
• C. Frostbite
• D. Trench foot

Answer: (B)

Hypothermia is a systemic state in which the body's core temperature drops due to cold exposure, affecting the entire body rather than just a localized area. This distinguishes it from other cold injuries: frostnip and frostbite are injuries to the skin and underlying tissues in exposed parts, not a body-wide temperature change, and trench foot results from prolonged exposure to cold and wet conditions causing tissue damage, again not a true whole-body temperature crisis. When hypothermia sets in, metabolic processes slow, and you can see signs from shivering and rapid breathing early on to confusion, slowed movements, and, if untreated, severe impairment or loss of consciousness as temperatures fall further. So, the description of a systemic cold emergency affecting the whole body points to hypothermia.
