To prevent patient injury when using an electrosurgical unit (ESU), which safety measures should be employed?

To prevent patient injury when using an electrosurgical unit (ESU), ensuring that audible alarms can be heard is a critical safety measure. Audible alarms serve as an alert system for the surgical team, indicating that the ESU is active or that there may be an issue that requires immediate attention. By ensuring that these alarms are audible, surgical personnel can promptly respond to any potential hazards, minimizing the risk of accidents and ensuring patient safety during procedures.

Effective communication and awareness within the operating room are paramount, particularly when dealing with high-risk equipment like an ESU. By relying on audible alerts, the team can maintain focus on the surgical procedure while still being alerted to any changes that could pose a risk to the patient. This helps prevent inadvertent burns or other complications associated with electrosurgery.

The other options do not contribute to safety in the context of using an ESU. Covering the generator with fluid can create a fire hazard, as fluids can conduct electricity and result in unintended injuries. Placing instruments directly on the ESU can lead to unintended activation, which may pose risks to both the patient and the surgical team. Using a sponge to soak up fluids near the footswitch could also pose a risk, as it can lead to unintentional
