Which statement about applying a hypothermia wrap is false?

• A. Insulation pad is placed between the person and the ground
• B. The head and neck should be covered with a cap
• C. A vapor barrier is used outside insulation wrap if the person is dry
• D. The wrap should be kept loose so air can circulate

Answer: (D)

When rewarming someone with a hypothermia wrap, the goal is to minimize heat loss by insulating the body and reducing heat exchange with the environment. Placing an insulation pad between the person and the ground helps prevent conductive loss to the cold surface. Covering the head and neck with a cap reduces heat loss from exposed areas, since the head can be a significant source of heat loss. Using a vapor barrier outside the insulation wrap for a dry person helps limit evaporative heat loss, keeping moisture from escaping. The wrap should be snug against the body, with minimal air gaps, to reduce convection and maintain warmth. Keeping the wrap loose would allow air to circulate and carry heat away, which is not desirable.
