Surgical Tech Practice Exam

The purpose of electrosurgery is to cut tissue or coagulate bleeding by using high-frequency electrical currents. This technique involves the use of an electrosurgical unit that delivers precise energy to tissue, effectively cutting through it while simultaneously coagulating blood vessels. This dual function minimizes bleeding and reduces the need for sutures since the heated tissue seals off blood vessels as it cuts. Electrosurgery is highly valued in surgical settings for its efficiency and effectiveness, allowing for cleaner surgical fields and reduced operative times.

In comparison to the other options, the removal of tumors may occur through various surgical techniques, including electrosurgery, but is not the specific purpose of the method itself. The administration of medications and monitoring of vital signs are also critical components of surgical procedures, but they pertain to different aspects of surgical care and do not relate to the primary function of electrosurgery. The distinctive ability of electrosurgery to simultaneously cut and coagulate is fundamental to its use in many types of surgical procedures.
