When Preparing for Pars Plana Vitrectomy in the Posterior Segment,the

When preparing for pars plana vitrectomy in the posterior segment,the perioperative nurse must be aware that a combined scleral buckling procedure may be necessary.Other important information the perioperative nurse should know before preparing the OR for the procedure includes the location of the ocular problem,the surgeon's plan to address the problem,and the instrumentation and biomedical equipment and devices to be used.Technologic advances in ophthalmic surgery require that perioperative nurses be familiar with complex biomedical equipment.A best practice,stated below,relevant to the safe use of complex equipment would be:

A) determine the presence and appropriate date (not expired) of the biomedical monitoring label.
B) demonstrate competence with equipment and check each piece carefully before the patient arrives in the OR.
C) schedule the manufacturer's representative to be present to provide technical support.
D) schedule the biomedical clinical engineer to check all equipment before each procedure.
