compare and contrast the three different classifications of burns.

Answer:

First - degree burns affect only the outer layer of skin (epidermis). They cause redness, pain, and mild swelling. Healing usually occurs in 3 - 7 days without scarring. Second - degree burns involve the epidermis and part of the dermis. Symptoms include blisters, severe pain, and swelling. Healing takes 2 - 3 weeks and may result in scarring. Third - degree burns damage all layers of the skin and may affect underlying tissues like muscle and bone. They appear white, charred, or leathery. There may be little pain initially due to nerve damage. Healing is slow, often requires skin grafts, and leads to significant scarring.
