What is a characteristic of a first-degree burn?

A first-degree burn is characterized by dry red skin without the presence of blisters. This type of burn affects only the outermost layer of the skin, known as the epidermis, leading to signs such as redness, slight swelling, and pain. The skin remains intact, which prevents blister formation.

In contrast, options that describe appearances of deeper burns are not applicable to first-degree burns. For instance, a burn that shows blisters would be classified as a second-degree burn, while a pearly, leathery appearance indicates a third-degree burn where the skin layers have been severely damaged. Burns that involve full thickness and affect muscle and bone fall into a severe category, also beyond first-degree burns, signifying extensive tissue damage and complexity in management. Thus, the correct identification of first-degree burns relies on recognizing their characteristic features, particularly the lack of blisters.
