Question

Initial first aid rendered at the scene of a fire includes preventing further injury through heat exposure. which intervention could contribute to tissue hypoxia and necrosis and therefore should be avoided?

Answer 1

Applying ice to a fire victim leads to tissue hypoxia and necrosis because it will change the skin's temperature too fast and may cause frostbite.  The burn could have had removed a layer of skin, leaving the fragile tissue exposed which will be more sensitive to the ice.
