For a patient with a burn, which characteristic would demonstrate a second-degree burn?

A second-degree burn, also known as a partial-thickness burn, is characterized by the presence of blisters and significant pain. This type of burn affects both the epidermis (the outer layer of skin) and part of the dermis (the second layer), leading to the formation of fluid-filled blisters. This blistering response is the body's way of protecting the underlying tissues while also indicating the severity of the injury.

Pain is a prominent feature because the nerve endings in the dermis are still intact and can perceive pain signals. Thus, the combination of blisters and painful skin distinctly describes a second-degree burn, making it the correct choice.

Understanding the characteristics of burns is crucial in the assessment and management of burn injuries, as it helps in determining the appropriate treatment and triage for patients affected by burns.
