Final answer:
It is false that ointments or antibiotic creams should be applied to treat a third-degree burn; instead, seek immediate medical attention.
Step-by-step explanation:
The correct answer to whether one should apply ointment or antibiotic cream to treat a third-degree burn is False. Third-degree burns are severe injuries that penetrate deep into the skin, affecting both the epidermis and the dermis and destroying tissue. These burns require professional medical attention. In the case of third-degree burns, applying ointments or creams can interfere with the treatment process and should not be done without instruction from a medical professional. Instead, the priorities for a third-degree burn are to prevent infection, protect the injured area from further damage, and seek immediate medical attention. Such burns carry a high risk of complications, and therefore, appropriate medical treatment including excision, possible amputation, and skin grafting may be necessary.
