What is an inappropriate instruction for caring for a child with a 2nd degree burn?

Applying butter or cooking oil for pain relief is an inappropriate instruction for caring for a child with a 2nd degree burn because these substances can trap heat and moisture in the skin, potentially leading to infection and further irritation of the burn. Instead of providing relief, they can worsen the injury. Appropriate first aid measures for a second-degree burn include cooling the area with cool (not ice-cold) water to reduce the temperature of the burn, covering it with a clean, dry cloth to protect the area and prevent contamination, and avoiding any home remedies that could introduce harmful substances or delay healing.

In treating burns, it is crucial to follow recommended protocols to promote healing and minimize complications, which include keeping the burn clean and allowing it to breathe without the application of oils or fats.
