What defines full-thickness burns?

Full-thickness burns are characterized by the destruction of both the epidermis and dermis, extending down to the subcutis, muscle, or even bone. This degree of burn damage means that the affected area may not exhibit pain since nerve endings are often destroyed, and it can appear leathery, waxy, or charred.

The other options describe different types of burns or their characteristics. For instance, burns that are moist and painful typically represent partial-thickness burns, which retain some level of sensation due to intact nerve endings. Redness and blisters indicate superficial to partial-thickness burns, where the skin is still capable of some healing and pain sensation. Lastly, describing a burn as mild with quick healing typically aligns with superficial burns, which are less severe and involve only the epidermis. Understanding these distinctions is crucial for effectively assessing burn injuries and determining appropriate treatments.
