For first aid treatment of a frostbite victim, which of the following is NOT acceptable?

Answer: C — Place hot water bottle on the frozen body part

When treating a frostbite victim, placing a hot water bottle on the frozen body part is not an acceptable method of care. The primary concern with this approach is that applying direct heat to a frostbitten area can cause further tissue damage. The skin and tissues in the affected area are already compromised by freezing, and the application of high temperatures can lead to burns or exacerbate the injury. Instead, appropriate measures involve gradually rewarming the affected area using body heat or warm (not hot) water immersion, ensuring that the rewarming process is controlled to avoid further injury. Covering the frozen body part helps to provide insulation and protection, while providing warm fluids can help stabilize the victim's body temperature from the inside. Additionally, encouraging movement or exercise of the affected body part can lead to more damage and compromise blood flow further, which is why it is best to keep the area as still as possible.
