An electrical burn injury may involve which of the following signs?

• A. Unconsciousness
• B. Only cosmetic skin changes with no pain
• C. Immediate recovery without symptoms
• D. Valuable loss of hair at the site

Answer: (A)

Electrical burn injuries can disrupt the nervous system and the heart, so loss of consciousness can occur if the current affects brain function, triggers an abnormal heart rhythm, or stops breathing. This makes unconsciousness a key sign to recognize in an electrical burn, because it points to more serious internal injury beyond what’s visible on the skin. The other options don’t fit typical signs: electrical burns aren’t usually limited to cosmetic skin changes with no pain, they don’t reliably present with immediate, symptom-free recovery, and hair loss at the burn site isn’t a dependable or common indicator of electrical injury. Recognizing that unconsciousness may accompany an electrical contact helps prompt urgent assessment and care.
