The entry wound in an electrical injury is defined as the location where electricity enters the body.

• A. Where electricity enters
• B. Where electricity leaves
• C. The maximum burn depth
• D. The site of contact with the power source

Answer: (A)

In electrical injuries, the entry wound is defined by the point where the electrical current first enters the body. This is the starting point of the current’s path, and it may be a small or even barely visible skin lesion, while serious damage often occurs along the internal path from entry to exit. The concept matters because the harm isn’t limited to the surface at entry; deep tissues, organs, and the heart can be affected as current travels through the body.

The other options don’t fit this definition. The site where electricity leaves the body is the exit wound, not the entry. The maximum burn depth describes how deep tissue injury can go along the current’s path, not the location of entry. The site of contact with the power source refers to where someone is touching the conductor, which may be the entry point but isn’t guaranteed to define the entry wound itself.
