Which type of gas is used to enhance the effectiveness of the electrosurgical unit active electrode pencil? A) argon B) CO₂ C) helium D) nitrous oxide

Question

Quizplus · Accepted Answer

Argon gas is often used in electrosurgery because it is inert and does not react with tissue. It is able to enhance the effectiveness of the active electrode pencil by providing an ionized gas around the tip, which improves the transfer of electrical energy to the tissue. Helium and nitrous oxide are not typically used in electrosurgery, and the option of "CO₂" is not a valid choice.
