Scenario 1: Routine ESU Setup for Abdominal Surgery

A 35-year-old female is scheduled for an uncomplicated open abdominal surgery. The surgeon plans to use monopolar electrosurgery for tissue dissection and haemostasis. The patient has intact skin, no implanted electronic devices, and no obvious fire-risk concerns. Assessment confirms a clean, dry, well-perfused return electrode site with adequate muscle mass. The ESU has been inspected and assembled, and all safety checks have been completed.

{Based on the assessment findings, what is the most appropriate next action before the incision is made?

	Delay surgery until bipolar electrosurgery becomes available
	Confirm generator settings, verify system readiness with the surgical team, and proceed with planned monopolar electrosurgery
	Remove the patient return electrode because the patient has intact skin
	Increase the generator power above the baseline settings before surgery begins

Which finding most strongly supports that the ESU is ready for safe use?

	The surgeon prefers monopolar electrosurgery
	The patient has normal laboratory results
	The active electrode has been removed from its sterile packaging
	Equipment inspection, return electrode placement, cable organization, functional testing, and generator readiness have all been confirmed

What is the most appropriate action before applying the patient return electrode?

	Select a different well-perfused muscular site with clean, dry, intact skin and prepare it appropriately
	Apply the return electrode over the hairy site because mild scarring is acceptable
	Increase the generator power setting to compensate for poor pad contact
	Proceed without a patient return electrode because only a small procedure is planned

Why is selecting an alternative return electrode site the safest decision in this scenario?

	Hair improves electrical conductivity and allows current to spread more evenly
	Mild scarring prevents the generator from producing electrical current
	Poor contact increases current density at the return electrode site, increasing the risk of thermal injury and burns
	Hair increases the likelihood of generator alarm failure

What is the most appropriate clinical decision?

	Apply the return electrode over the least damaged area and continue with monopolar electrosurgery
	Stop ESU setup, inform the surgical team, and determine whether a safe alternative such as bipolar electrosurgery or another haemostatic method is appropriate
	Increase the size of the return electrode to compensate for poor skin quality
	Reduce the generator power setting and proceed with monopolar electrosurgery

Which principle best supports delaying monopolar electrosurgery in this patient?

	Minor surgical procedures do not require electrosurgical equipment
	Return electrode placement is optional if the operative field is small
	Wet skin improves current dispersal and reduces burn risk
	Monopolar electrosurgery should not be used unless a safe return electrode site can be established to complete the electrical circuit safely

What is the most appropriate action before monopolar electrosurgery is activated?

	Replace monopolar electrosurgery with bipolar electrosurgery without consulting the surgeon
	Communicate the presence of the pacemaker to the surgical and anaesthesia teams, follow institutional precautions, and ensure the return electrode is positioned to minimise current flow near the device
	Increase the generator power setting to shorten activation time
	Cancel the procedure because electrosurgery is always contraindicated in patients with pacemakers

Why is communication between the perioperative nurse, surgeon, and anaesthesia provider especially important in this scenario?

	To determine whether the patient requires additional laboratory tests before surgery
	To decide whether the patient should receive additional skin preparation
	To determine whether the patient should receive prophylactic antibiotics
	To ensure the implanted device is recognised, appropriate precautions are implemented, and the electrical current pathway is managed as safely as possible

What is the most appropriate immediate response by the perioperative nurse?

	Stop the planned activation, communicate the fire hazard to the surgical team, and ensure the risk has been eliminated before electrosurgery proceeds
	Activate the ESU briefly because the planned activation will only last a few seconds
	Increase suction near the operative field while allowing electrosurgery to proceed
	Reduce the generator power setting before activation

Before electrosurgery can safely proceed, which combination of actions is most appropriate?

	Increase oxygen delivery, dry the active electrode, and increase generator power
	Leave the wet skin preparation in place but replace the patient return electrode
	Allow the alcohol-based skin preparation to dry completely, reduce oxygen enrichment where clinically appropriate, confirm fire precautions with the surgical team, and then proceed
	Replace monopolar electrosurgery with bipolar electrosurgery without addressing the wet preparation or oxygen
