Final answer:
The family can be with the patient in the preoperative holding area, and then again in the postanesthesia care unit.
Step-by-step explanation:
The perioperative nurse should explain to the student nurse that the family can be with the patient in the preoperative holding area. This is the area where the patient prepares for surgery, and it is typically the last opportunity for the family to be with the patient before the surgery begins. Once the patient is taken into the surgical suite, the family will not be allowed to be with the patient until the postanesthesia care unit.
