Johnny Parker (DOB 06/15/10) saw Jean Burke, NP, for a well-child visit. Johnny is off schedule with his hepatitis B vaccine series, and today he is to get his last hepatitis B booster. You (a medical assistant) prepare the medication and give the injection in his right deltoid muscle. Later in the day, you realize that hepatitis B has been out of stock for 1 week. You must have given a hepatitis A booster to Johnny. You realize that you failed to read the label three times during the preparation of the medication. You report the mistake to Jean Burke, NP, and your supervisor. Your supervisor calls Lisa Parker, Johnny's mother. They will come back next week for the hepatitis B vaccine. You need to complete the incident report.
