What should NOT be done when treating a mild partial thickness burn?

When treating a mild partial thickness burn, it is crucial to protect the injury and promote healing. Breaking any blisters that form is not advisable because the blister serves as a natural barrier against infection and helps keep the underlying tissue moist, which is beneficial for healing. By breaking the blister, you expose raw skin to potential contaminants and increase the risk of infection.

Using a dry sterile dressing is appropriate as it protects the burn area from further injury and contamination, while flushing the burn with cool water helps to cool the area and relieve pain. Elevating the affected body part can reduce swelling and improve circulation, making it a proper action in managing burn injuries. Thus, while the other actions contribute positively to the treatment, breaking blisters could lead to complications and hinder recovery.
