Which finding is most indicative of an electrical burn rather than a thermal burn?

• A. Visible entry and exit wounds and potential deep tissue injury
• B. Only superficial redness and swelling
• C. Lack of deep tissue injury
• D. Immediate burn uniformity

Answer: (A)

Electrical injuries cause damage along the path the current takes through the body, so you often see both an entry wound and an exit wound, with the real harm occurring in deep tissues even if the skin looks only mildly burned. That combination—visible entry and exit wounds with potential deep tissue injury—best signals an electrical burn. In contrast, a burn that is mostly superficial redness and swelling points to a thermal burn, not electricity. Electrical injuries can also produce deep internal damage despite an apparently small surface wound, and the burn surface may be irregular rather than uniform, so immediate uniformity isn’t a reliable indicator.
