Electrical burns are often associated with what risk compared to their external appearance?

• A. Greater internal injuries than external wounds suggest; may cause VF arrest
• B. Always minimal damage
• C. Only affects skin color
• D. Never cause heart rhythm problems

Answer: (A)

Electrical burns can cause serious internal damage that isn’t obvious from the outside. The current can travel through the body along the path of least resistance, injuring nerves, muscles, and internal organs even when the skin looks only lightly burned. The heart’s electrical system is especially vulnerable, so electrical injury can trigger life-threatening rhythm disturbances such as ventricular fibrillation and even cardiac arrest. The risk depends on voltage, amperage, whether the current is alternating or direct, how long the exposure lasts, and the route the current takes through the body. Because of this, a patient with an electrical burn must be monitored for potential dysrhythmias and other internal injuries, and transported for definitive care, even if external wounds seem minor. This helps explain why the correct answer emphasizes greater internal injuries and potential heart rhythm problems despite minimal external signs.
