How should you care for a patron with a painful, blistered burn?

Cooling the burn with water and continuing until the pain is relieved is the appropriate course of action for a painful, blistered burn. The rationale behind this approach is that cooling the burn lowers the skin temperature, which helps to reduce inflammation and alleviates pain. Ideally, the water should be cool, not icy, to avoid further tissue damage. This method also promotes healing by preventing the burn from worsening.

Applying ice directly to the burn, as suggested in another option, can actually cause frostbite or further damage to the tissue, which is why it is not advisable. Covering the burn with ointment immediately can trap heat and moisture in the area, potentially worsening the pain and hinder the body's natural healing process. Keeping the burn dry and bandaged, while important for some types of injuries, is not the first step in this case as it does not address the immediate need for cooling and pain relief.
