Final answer:
When responding to a victim with an electrical burn, the EMS provider should check for entry and exit wounds and administer oxygen via nasal cannula.
Step-by-step explanation:
When an EMS provider is called to the scene where a victim has sustained an electrical burn, it is important for the EMS provider to check the patient for entry and exit wounds. This is because electrical burns can cause internal injuries that may not be immediately visible. By checking for entry and exit wounds, the EMS provider can assess the extent of the injury and provide appropriate medical treatment. It is also important to administer oxygen to the patient via nasal cannula to ensure that they are receiving enough oxygen to support their body functions during the emergency situation.
