Answer to Question 1

ANS: C
The dispersive electrode should not be placed on skin over a metal implant and should be placed over or under as large a muscle mass area as possible. It should be placed closest to the incision, thus the right thigh would be an adequate site.

Answer to Question 2

ANS: C
Electrosurgery should not be used in the mouth, trachea, around the head, or in the pleural cavity when high concentrations of oxygen or nitrous oxide are used. During eye surgeries, oxygen is administered via nasal cannula or mask. Oxygen can build up under the drapes and cause a combustible situation to develop.
