Which description matches a 3rd degree burn?

Which description matches a 3rd degree burn?

• A. Affects only epidermis
• B. Injury to muscle and bones
• C. Contains blisters but not nerve damage
• D. Affects all layers of the skin; nerve damage depicts pain

Answer: (D)

3rd-degree burns involve full-thickness damage through the skin, reaching all layers and often destroying the nerve endings in the area. Because those nerves are damaged, the burned patch itself may be numb, though surrounding tissue can be very painful. This depth and nerve involvement distinguishes it from milder burns that only affect the epidermis (first-degree) or burns that extend into deeper structures like muscle or bone (beyond the skin, often described as fourth-degree). The description that mentions blisters with no nerve damage fits a superficial second-degree burn, not a 3rd-degree burn.
