Question

Third degree burns differ from the first and second degree burns in that

A. The epidermis, dermis, and hypodermis are destroyed
B. They're more painful
C. Fluid accumulates between the dermis and epidermis
D. The burn is restricted to the superficial layers of the skin

Answer 1

Third-degree burns differ from first and second-degree burns in that the epidermis, dermis, and hypodermis are destroyed.

Step-by-step explanation:

Third-degree burns differ from first and second-degree burns in that the epidermis, dermis, and hypodermis are destroyed. While a first-degree burn affects only the epidermis and a second-degree burn affects both the epidermis and a portion of the dermis, third-degree burns extend through the full thickness of the skin, causing serious tissue damage. Contrary to what might be expected, third-degree burns are often less painful because the nerve endings are damaged, which can reduce the sensation of pain. On the other hand, first and second-degree burns can be quite painful as the nerve endings are still intact. It's essential for third-degree burns to receive medical attention, as they require more complex treatments such as excision (debridement) or skin grafting from an unaffected part of the body, or even skin grown in tissue culture. The severity of these burns makes them more susceptible to complications like dehydration, electrolyte imbalance, and infections, due to the loss of protective skin layers. Unlike more superficial burns, which may heal on their own, third-degree burns cannot be repaired by the body alone because the local tissues used for repair are also damaged.
