You are about to sterilize a set of loaner instruments for a surgery scheduled for the following day. You have already written down the sterilization date, your identification, and storage destination. However, you are interrupted by a phone call before you could finish the labeling. After the phone call, you realize you have not added any special identifier. What should you do?
