In the case of burns, the involvement of the epidermis only comes under:

Correct option is A

Ans. (a) Sol. The correct answer is (a) First degree.
First-degree burns only affect the epidermis, which is the outermost layer of the skin. These burns are characterized by redness, pain, and minor swelling, but they do not cause blisters or affect deeper layers of the skin. Sunburn is a common example of a first-degree burn.
Explanation of each option:
· (a) First degree: Correct answer. First-degree burns involve only the epidermis and are usually mild, with redness, pain, and no blistering.
· (b) Second degree: Second-degree burns affect both the epidermis and part of the dermis (the second layer of skin). These burns cause blistering, pain, and swelling.
· (c) Third degree: Third-degree burns involve full-thickness damage, affecting the epidermis, dermis, and often the underlying tissue. These burns result in white, charred, or leathery skin, and there is often no pain due to nerve damage.
· (d) Fourth degree: Fourth-degree burns extend beyond the skin and involve deeper tissues, such as muscles, tendons, or bones. These burns are the most severe and can be life-threatening.
Thus, first-degree burns involve only the epidermis.
