What additional injuries can result from electrical injuries?

When considering the consequences of electrical injuries, it is critical to understand that the impact can extend beyond just burns. The correct choice highlights that electrical injuries can lead to ruptured tympanic membranes and fractures, which are primarily caused by violent muscle contractions induced by the electrical current.

When a person is exposed to an electrical current, various physiological responses can occur, including tetany, where muscle contractions do not relax. This intense contraction can result in physical trauma, such as fractures, especially if the person falls or is jolted. Additionally, the sudden changes in pressure within the body due to the intense contraction can lead to ruptured tympanic membranes. The ears, being sensitive and delicate structures, can rupture if subjected to the pressure changes from muscle activity triggered by electrical shock.

The other options listed do not encompass the full range of potential additional injuries associated with electrical shocks. While burns are a common direct result, they do not represent the range of bodily harm that can occur from electrical exposure. The particular injuries highlighted in the correct choice are specific to the dynamics of electrical injuries and their interactions with bodily functions.
