A partial-thickness burn affects which part of the skin?

• A. epidermis
• B. fatty layer
• C. muscle fascia
• D. dermal layer

Answer: (D)

A partial-thickness burn, often referred to as a second-degree burn, affects both the epidermis and part of the dermal layer of the skin. This type of burn results in damage that extends beyond the outer layer of skin (the epidermis) and into the dermis, which contains blood vessels, hair follicles, and nerve endings. In the context of the choices provided, while the dermal layer is impacted, it is important to note that the primary characteristic of a partial-thickness burn involves injury to both the epidermis and the dermis. This burn is typically associated with signs such as redness, swelling, blistering, and pain. The dermis plays a crucial role in the healing process, as it contains the necessary cells for regeneration and repair of the skin. Thus, recognizing that a partial-thickness burn affects the layers of skin, including the dermis, is critical in understanding how the skin reacts to thermal injuries and the implications for treatment and healing.
