Which step should be taken when managing a burn wound?

Cooling the burn with running water is crucial in the management of a burn wound because it helps to reduce the temperature of the burn area and alleviates pain. Applying cool running water not only diminishes the heat in the tissue, which can prevent further damage, but it also promotes a more favorable healing environment. This step is effective if done within the first few hours after the burn occurs, ideally for about 10 to 20 minutes.

Using running water helps to stop the burning process and can also help to clean the wound, reducing the risk of infection as it flushes away debris and contaminants. This is a widely accepted method for immediate first aid treatment for burns and is recommended by healthcare professionals.

The other methods listed do not provide the same level of care or can even cause harm. For example, wrapping a burn tightly can impair blood flow and exacerbate pain and swelling, while leaving the burn exposed may expose it to potential infections. Applying butter is a common misconception that can actually trap heat and bacteria, worsening the burn. Thus, cooling the burn with running water is the best practice for initial burn management.
