A patient performing home renovations is brought to the emergency department with electrical burns. When assessing the patient, the nurse should recall that:
A) bone has a lower resistance than other body tissues.
B) electricity bounces off bone toward soft tissues.
C) electrical damage follows a straight path through the body.
D) most tissues of the body are insulators.
B) electricity bounces off bone toward soft tissues.
Explanation: A) Although bone will still conduct current, it has a higher resistance than other tissues in the body.
B) Because electricity follows the path of least resistance, the practitioner must consider the path of the electrical injury as it bounces off hard surfaces such as bone toward soft tissues such as arteries, muscles, and organs.
C) Damage does not necessarily follow a straight path; however, the damage will follow a path parallel to that of the electricity conducted through the body.
D) Materials that enhance the flow of electrical current are called conductors; materials that slow or stop the conduction of electrical current are called insulators. Most of the tissues of the body are conductors, easily allowing the flow of electrical current through body tissues.
