Second-degree burns are characterized by which description?

Second-degree burns are characterized by which description?

• A. Involve only the outer layer of skin.
• B. Extend through outer and inner layers and involve blisters, severe pain, redness, and warmth.
• C. Pain is absent due to nerve destruction.
• D. Always painless.

Answer: (B)

Second-degree burns are partial-thickness injuries that involve both the epidermis and part of the dermis. This depth disrupts skin structure enough to cause fluid-filled blisters, redness, warmth, and significant pain because many nerve endings remain intact and irritated. This explains why these burns are not just a superficial reddening; the blistering reflects dermal involvement, and the ongoing pain comes from preserved nerves in the affected area. Compare this to burns that affect only the outer layer, which are typically classified as first-degree: they’re usually red and painful but don’t form blisters. In contrast, burns that destroy all skin layers extend into deeper tissues and are often described as third-degree, where nerve damage can lead to little or no pain. The description that mentions extending through outer and inner layers with blisters, severe pain, redness, and warmth best matches partial-thickness involvement.
