E) A first-degree burn destroys the epidermis, the dermis, and extends into the subcutaneous layer. A second-degree burn affects only the surface of the skin. A third-degree burn affects the whole epidermis and some of the dermis.

Answer 1

The correct distinctions between the burn degrees are that a first-degree burn affects only the surface, a second-degree burn affects both the epidermis and part of the dermis and a third-degree burn destroys both layers and reaches into the subcutaneous layer. The option (C) is correct.

Step-by-step explanation:

Among the options provided, the correct distinction between first-degree, second-degree, and third-degree burns is A first-degree burn affects only the surface of the skin. A second-degree burn affects the whole epidermis and some of the dermis. A third-degree burn destroys the epidermis, and the dermis, and extends into the subcutaneous layer.

A first-degree burn is essentially a superficial burn that only affects the epidermis. An example of this would be a mild sunburn. On the other hand, a second-degree burn is more serious as it penetrates deeper, causing damage to both the epidermis and the dermis, leading to swelling and blistering of the skin. Lastly, a third-degree burn is the most severe out of the three as it extends through the entire epidermis and dermis, reaching into the subcutaneous layer, and requires medical attention for proper healing. Therefore, option (C) is correct.
