What should the surgical technologist do before closing the uterus during a myomectomy?

Before closing the uterus during a myomectomy, initiating the cavity count is essential because it ensures that all surgical instruments and materials used during the procedure are accounted for and that no foreign objects are inadvertently left inside the uterine cavity. This step is crucial for patient safety and helps prevent complications that could arise from retained items, such as infection or internal injury. In this context, the cavity count specifically refers to accounting for any tissue or items within the cavity that could affect healing or lead to postoperative complications.

The other tasks listed, such as initiating the closing count, obtaining sterile wound dressing material, and weighing the myoma, are also important aspects of the surgical process but are not specific to the immediate steps required before closing the uterus. Each of these actions serves its purpose in the overall surgical protocol, but the cavity count directly addresses the need for meticulous attention to the contents of the uterine cavity right before closure, highlighting the correct choice in this scenario.
