A. First degree
B. Second degree
C. Third degree
D. None of these

Answer 1

The presence of blisters due to excessive exposure to UV radiation classifies the burn as a second-degree burn.

Step-by-step explanation:

Excessive exposure of the skin to UV radiation may cause redness, edema, blisters, and pain. The presence of blisters classifies the burn as a second-degree burn. Second-degree burns affect both the epidermis and a portion of the dermis, resulting in swelling and painful blistering of the skin. In contrast, a first-degree burn affects only the epidermis, and a third-degree burn fully extends into the epidermis and dermis, destroying the tissue and affecting nerve endings and sensory function. It is crucial to keep the burn site clean and sterile to prevent infection and to ensure proper healing.
