:  Patients desire more details and specifics about the surgery.  For example, the nurse may tell the patient that an IV (intravenous) line will be started while you are asleep in the holding area; the surgeon may mark the operative site with an indelible marker to verify site and side for the surgical procedure.
Term
Process Information
