The white coat is worn into and out of the hospital and removed before going onto the floor to take care of patients. In theory, it prevents carrying germs in on your uniform. It is worn when going to the cafeteria, to contain germs to the scrubs and not onto your tray. The ceremony stresses the commitment to excellent patient care at a time before the very first clinical. It will hopefully give nursing students the awe-factor of exactly how important their role and responsibility is to a vulnerable patient.
