What is the difference between a first-degree burn and a second-degree burn?

• A. A first-degree burn affects the epidermis; a second-degree burn affects the hypodermis
• B. A first-degree burn is more severe than a second-degree burn
• C. A first-degree burn affects only the epidermis; a second-degree burn extends into the dermis
• D. A first-degree burn causes blisters; a second-degree burn does not

Answer: (C)

The correct response identifies the anatomical differences between first-degree and second-degree burns, focusing on the layers of the skin involved. A first-degree burn is characterized by damage that is limited to the outermost layer of the skin, which is the epidermis. This type of burn typically results in redness, minor swelling, and pain but does not cause blisters.

In contrast, a second-degree burn extends deeper into the skin by affecting not only the epidermis but also the underlying layer known as the dermis. This deeper penetration leads to symptoms such as blisters, significant swelling, and more intense pain compared to first-degree burns. By accurately specifying that a first-degree burn affects only the epidermis and a second-degree burn affects the dermis, the response clarifies the severity and implications associated with each type of burn in terms of healing, treatment requirements, and potential complications.

Other options do not correctly describe the injury depth or severity, contributing to an understanding of burn classifications and their clinical significance.
