Which statement about second-degree burns is correct?

• A. Affects only the outer skin layer
• B. Involves both epidermis and dermis with blisters
• C. Affects underlying muscles
• D. Affects nerves only

Answer: (B)

Second-degree burns involve both the epidermis and the dermis, which is why blistering occurs as these layers separate and fluid collects between them. The damage to both skin layers leads to redness, swelling, and notable pain, with the skin often appearing moist or shiny. This depth is deeper than a first-degree burn (which stays in the outer layer) but not as deep as injuries that reach underlying muscles or deeper structures, which would be third-degree burns. Nerve endings in the damaged dermis contribute to the intense pain, but the injury is not limited to nerves only—the skin layers themselves are involved.
