sleeve caught fire
while she was cooking.
Her arm looked terrible but
it didn’t hurt. The skin was charred.
Her husband took off her blouse and
picked off bits of the blouse stuck to the burn.
He then placed butter on the burn
and covered it with
a wet bandage.

Based on this, we can know his burn belongs to third dgree burns.
Based on para 5, he was right to take off her wife’s blouse but he shouldn’t have picked off bits of blouse off the burn. Because if you pull the clothes that are stuck to the burn, you would pull the tissue under clothes off too. This would cause more damage to the burn.
He shouldn’t have placed butter on the burn because it would prevent the heat from escaping and cause infection.
He shouldn’t have put a wet but a dry bandage on the burn.
