Which of the following burns would be classified as a second-degree burn?

A second-degree burn is characterized by damage to both the epidermis and part of the dermis, which typically results in symptoms such as blistering and significant pain. When the skin is burned to this extent, the affected area appears red and swollen, and blisters may form as the body attempts to heal itself. The pain is often more intense than that of a first-degree burn due to the involvement of deeper skin layers, which contain more nerve endings.

The option describing a burn that is charred and insensitive to pain indicates third-degree burns, where the skin's layers are severely damaged, leading to a lack of sensation. The red and dry burn refers to a first-degree burn, which affects only the outermost layer of skin (epidermis) without blistering. Finally, a burn that affects the epidermis only aligns with a first-degree burn as well, which does not involve the dermis and presents symptoms different from those of a second-degree burn. Thus, the description that includes blisters and pain effectively identifies a second-degree burn.
