Which approach best supports an efficient surgical workflow?\n|type=\"()\"}\n- Arrange instruments according to the order they were sterilized\n|| ''Sterilization order does not support intraoperative efficiency.''\n- Group all instruments of the same size together regardless of their function\n|| ''Organization by function and anticipated sequence is more useful during surgery.''\n- Keep all instruments inside their trays until the surgeon requests them\n|| ''This may delay instrument presentation during the procedure.''\n+ Arrange instruments in the approximate order they are expected to be used while keeping similar instruments logically grouped\n|| '''Logical organization helps the scrub nurse anticipate the surgeon's needs and reduces unnecessary delays.'''\n\n{Before surgery begins, why should compatibility between laparoscopic equipment and instruments be verified?\n|type=\"()\"}\n+ To ensure that instruments, accessories, and equipment function safely together throughout the procedure\n|| '''Compatibility checks help prevent equipment failures, connection problems, and unnecessary delays during surgery.'''\n- To determine which instruments should be sterilized after the procedure\n|| ''Sterilization decisions are unrelated to equipment compatibility.''\n- To reduce the number of instruments required on the sterile field\n|| ''Instrument selection depends on the planned procedure rather than compatibility alone.''\n- To allow disposable instruments to be reused if compatible\n|| ''Disposable instruments should never be reused unless specifically designed for reprocessing.''\n\n{When passing a laparoscopic instrument to the surgeon, which technique best supports safe handling?\n|type=\"()\"}\n- Hold the instrument by its working tip so the surgeon can grasp the handle quickly\n|| ''Holding the working tip is unsafe and may damage the instrument or increase the risk of injury.''\n+ Present the instrument by the shaft with the jaws closed and the handle positioned for a natural grip\n|| '''This technique allows safe transfer while enabling the surgeon to receive the instrument comfortably and efficiently.'''\n- Pass the instrument with the jaws open to demonstrate that it functions correctly\n|| ''Passing instruments with open jaws increases the risk of injury and equipment damage.''\n- Place every instrument directly onto the Mayo stand for the surgeon to retrieve independently\n|| ''Instruments are normally passed directly unless a neutral zone is being used for sharps.''\n\n{Why is it important to avoid twisting instrument cables around the camera cable during surgery?\n|type=\"()\"}\n- Twisting the cables makes them more difficult to sterilize after the procedure\n|| ''Sterilization occurs after the procedure and is not the primary concern.''\n- Twisting the cables may interfere with monitor positioning\n|| ''Monitor position is generally unaffected by cable twisting.''\n- Twisting the cables makes instrument passing more difficult but does not affect equipment performance\n|| ''Twisting may also damage equipment.''\n+ Twisting may damage cable insulation, reduce equipment performance, and increase the risk of equipment failure\n|| '''Repeated torsion can damage delicate cables and compromise the safe operation of the laparoscopic system.'''\n\n{A laparoscopic instrument has been dropped onto the operating room floor during setup. What is the most appropriate action?\n|type=\"()\"}\n- Wipe the instrument with sterile saline and return it to the sterile field\n|| ''Wiping the instrument does not restore sterility or confirm that the instrument has not been damaged.''\n- Continue using the instrument if no visible damage is present\n|| ''Even without visible damage, the instrument is no longer considered sterile and may also have sustained hidden damage.''\n+ Remove the instrument from the sterile field and replace it with a sterile instrument after confirming a suitable replacement is available\n|| '''Dropped instruments are considered contaminated and should be replaced before surgery continues.'''\n- Place the instrument aside for inspection after the procedure and continue if no alternative is available\n|| ''Contaminated instruments should not be used during surgery, regardless of instrument availability.''\n</quiz>{{Return to main}}{{Page data\n| part-of = Laparoscopic Surgery - ECSACONM\n| keywords = surgery, health\n| sdg = SDG03 Good health and well-being\n| organizations = ECSACONM, SELF\n}}"}
