B) metal to tissue; the scrub person
C) active burns; the surgeon
D) metal-to-metal sparking; the surgeon

Question

Quizplus · Accepted Answer

Direct coupling occurs when the active electrode accidentally touches a noninsulated metal instrument,allowing the electrical energy to flow from one to the other (metal-to-metal sparking).Direct coupling may also occur if an active electrode is activated while in contact with a clip.When the metal instrument or clip receives electrical energy,a burn can easily result.This coupling is often called "pilot error" because it is within the surgeon's control to avoid.The surgeon should not activate the active electrode until the target site is within the field of vision,and the active electrode is in proximity or direct contact with target tissue and not a metal object.
