Final answer:
For a partial-thickness burn, you should cover the burn with a moist, sterile dressing, cool the area with cool water, and not rupture any blisters to prevent infection.
Step-by-step explanation:
When treating a partial-thickness burn, the best course of action is to cover the burn with a moist, sterile dressing. A partial-thickness burn, also known as a second-degree burn, affects both the epidermis and a portion of the dermis. These types of burns result in swelling and blistering of the skin and it is crucial to keep the burn site clean and sterile to prevent infection. The correct procedure involves cooling the burn with cool (not cold) water for several minutes, then covering it with a moist sterile dressing to protect the area and to minimize pain. It is important to not break any blisters as this increases the risk of infection. Avoid the use of creams, lotions, or antiseptics unless directed by a medical professional.
