Which of the following is a symptom of a first degree burn?

A first degree burn primarily affects the outer layer of the skin, known as the epidermis. Symptoms associated with first degree burns include redness, minor swelling, and tenderness in the affected area. The mild swelling is due to the inflammatory response of the body as it works to heal the injury.

In contrast, blistering is associated with second degree burns, where the dermis (the second layer of skin) is also affected. A charred or white appearance, along with a wet appearance, often indicates more severe burns (second or third degree), where deeper layers of skin are damaged. Understanding these distinctions is crucial for accurately assessing and responding to burn injuries in a security or first aid context.
