A. Shivering is a common response to cold therapy (such as a hypothermia blanket) as the body attempts to maintain its core temperature. This can increase metabolic demands and oxygen consumption, which should be closely monitored.
B. Seizures are not typically associated with the use of hypothermia blankets unless there are underlying conditions that predispose to them.
C. Dehydration could occur with any prolonged therapy but is not the immediate concern with hypothermia blankets.
