Which statement is true regarding second-degree burns?

Second-degree burns, also known as partial thickness burns, involve damage to the epidermis and portions of the dermis but do not penetrate the deepest layers of skin, which include the subcutaneous tissue. This is why stating that second-degree burns do not damage the deepest layers of skin is accurate.

In addition to being limited to the epidermis and part of the dermis, second-degree burns can result in significant pain, swelling, and redness. Blistering is also characteristic of these burns, as the injury affects the deeper skin layers but not all the way down to the underlying fat.

The incorrect choices highlight different conditions that pertain to other degrees of burns—first-degree burns are superficial and do not affect the dermis, while third-degree burns involve damage through the dermis and into deeper tissues. Additionally, loss of sensation is more relevant to third-degree burns, as they can destroy nerve endings in the skin, rendering the area numb. Lastly, while electrical injuries can cause burns, they are more commonly associated with third-degree burns, which can be more severe and damaging than those classified as second-degree.
