3. Which type of burn involves both the epidermis and dermis layers of the skin? a. Partial thickness b. Superficial c. Full thickness d. Surface

The correct answer is a. Partial thickness.Partial thickness burns involve both the epidermis and dermis layers of the skin. These burns can be further classified into two categories:1. First-degree burns: These burns affect only the outermost layer of the skin, the epidermis. They cause redness and pain but do not involve the dermis.2. Second-degree burns: These burns extend beyond the epidermis and affect the dermis layer of the skin. They cause blistering, swelling, and severe pain.In contrast, full thickness burns (option c) involve the entire thickness of the skin, including both the epidermis and dermis layers. Superficial burns (option b) affect only the outermost layer of the skin, while surface burns (option d) are not a recognized classification of burns.
