To reduce the possibility of an injury or burn, which of the following most
accurately describes where the perioperative RN should place the dispersive
electrode?
a. As far from the operative site as feasible.
b. Directly on the operative site.
c. As close to the operative site as feasible.
d. Anywhere it will be easy to access.
c. As close to the operative site as feasible. - should be placed over a large, well
perfused muscle mass, which will permit uniform contact.

collected in the dispersive pad, and returns to the generator.
b. Current leaves the generator, is applied to tissue using a pencil device, and
returns to the generator.

and returns to the generator.
If the surgeon continuously asks for higher power settings, what is the first
action that the perioperative nurse should take?
a. Get another ESU unit immediately.
b. Check the circuitry for possible disruption.
c. Switch to a bipolar generator and electrode.
d. Change the active electrode and dispersive electrode.
b. Check the circuitry for possible disruption.
Alternate pathway burns can occur because of improper placement of the
dispersive electrode. The dispersive electrode SHOULD NOT be applied on
which of the following:
select all that apply
a. Hairy skin surfaces
b. Burn tissue
c. Tattoo sites
d. Well-perfused muscle

When using argon- enhanced coagulation (AEC), there is a risk of __________.
a. electrosurgical injury
b. carbon dioxide purge

system, so there is a risk of gas embolism when the active electrode is placed in
direct contact with tissue.

evacuation of smoke from the surgical site. Which of the following are
considered LEV?
select all that apply
a. Central suction system with an in line filter.
b. HEPA filter

Which precautions should be taken for a patient who has an implantable
electronic device (IED)?
select all that apply
a. All team members should be informed about the IED.

c. There should be continuous EKG monitoring.
d. The active and dispersive electrodes should be located as close together as
possible.
A, C, & D
During laparoscopic surgery, perioperative RNs can reduce the chances of
capacitive-coupling injuries by:
a. using a combination of insulated and non-insulated instruments.
b. using a coagulation waveform and a high setting.
c. using metal and plastic cannulas together.
d. using the lowest power settings and the low voltage cutting waveform.
d. using the lowest power settings and the low voltage cutting waveform.

which of the following are recommended components of documentation when
using an ESU?
select all that apply
a. ESU brand name
b. Name of the person applying the dispersive pad.

a. scrubs; paints
Transient microorganisms live in the ________ layer of the skin.
a. epidermal
b. dermal
c. fatty (adipose)
d. all of the above
a. epidermal
Which of the following agents are antimicrobial agents?
select all that apply
a. Chlorhexidine gluconate (CHG)
