Which of the following is a characteristic feature of second degree burns?

Second-degree burns, also known as partial-thickness burns, are characterized by damage that extends beyond the outer layer of skin (epidermis) and into the underlying layer (dermis). The presence of blisters is a hallmark of this type of burn. These blisters are formed due to the accumulation of fluid between the layers of skin, indicating a significant injury that affects the dermis.

In addition to blister formation, second-degree burns are typically painful due to the exposure of nerve endings within the dermis. The injured area will appear red and swollen as a result of inflammation and increased blood flow to the affected tissue as part of the body’s healing response. This combination of symptoms—blisters and pain—is integral to identifying a second-degree burn as opposed to first-degree, which involves only the epidermis and presents as red and swollen without blisters, or third-degree burns, which can be dry and leathery and may not be painful due to nerve damage.

Understanding these characteristics is crucial for appropriate assessment and management of burn injuries.
