What is a likely consequence of a third degree burn?

A third-degree burn, also known as a full-thickness burn, is characterized by extensive damage to the skin layers, which can include the epidermis, dermis, and potentially subcutaneous tissues. This damage leads to a significant loss of sensation in the affected area due to the destruction of nerve endings. Therefore, while the burn is severe, the area may not be as painful as a second-degree burn because the nerves are damaged.

The correct answer reflects that a third-degree burn impacts not only the skin but also the underlying tissues, including fat, muscle, and sometimes even bone. This extensive damage can result in complications such as infections, significant scarring, and in some cases, the need for surgical interventions like skin grafts.

Other options provided do not cover the severity of third-degree burns accurately. Minor blistering is associated with first-degree or mild second-degree burns, and swelling without the need for medical attention downplays the seriousness of third-degree burns, which typically require immediate medical care. The aspect of pain being less than in second-degree burns also misrepresents the nature of this injury, as the lack of sensation in severely burned areas can lead to a misconception about pain levels.
