As part of a first aid class, a health care instructor is teaching a group of industrial workers about how electrical injuries can cause cell damage. Which of the statements made by one of the workers indicates that further teaching is necessary? A) The greater the skin resistance, the greater the amount of deep and systemic damage a victim is likely to incur
B) The particular pathway that a current takes through the body is very significant.
C) Resistance to flow is the phenomenon that transforms electrical energy into heat.
D) The most severe damage is likely to occur where the current enters and leaves the body.
Ans: A
Feedback: High skin resistance is associated with greater local and superficial burns, rather than deep and systemic damage. The pathway is indeed an important factor in the degree of injury, and this is a result of the transformation of current into heat. Damage is most severe at the point of entry and exit.
