Final answer:
True, second-degree burns involve damage to both the epidermis and parts of the dermis, leading to blistering and requiring proper wound care.
Step-by-step explanation:
The statement is true: In second-degree burns, both the epidermis and parts of the dermis are indeed involved and damaged, commonly leading to painful swelling and blistering of the skin. These partial-thickness burns are more severe than first-degree burns but less severe than third-degree burns, which destroy the full thickness of the skin and affect nerve endings and sensory function. Proper care including keeping the site clean and sterile is crucial for healing second-degree burn injuries.
