What are the signs and symptoms of third degree burns?

Third-degree burns are characterized by their significant depth, affecting all layers of the skin, which can include the epidermis, dermis, and subcutaneous tissue. The correct choice is the one that describes the appearance and sensation associated with this severity of burn.

White or charred tissue is a hallmark of third-degree burns, indicating that the skin has been extensively damaged and possibly destroyed. The lack of pain, or only mild discomfort, is due to the destruction of nerve endings in the affected area. This leads to a profound loss of sensation, which can be misleading for the severity of the injury—it may appear less painful than it actually is.

In contrast, the other choices represent characteristics of less severe burns. Red and painful skin generally describes first-degree burns, while blisters filled with fluid are typical of second-degree burns. Swelling with no pain may occur with other types of injuries but does not accurately represent the distinctive nature of third-degree burns. Understanding the specific signs and symptoms of burn severity is crucial for proper assessment and treatment.
