Medication errors are going to happen and nurses will learn to deal with it. I am very glad you was honest to report the error. Unfortunately, some supervisors or nurse managers do not always deliver the appropriate tone or manner when dealing with these kind of events. When an error occur, learn from it and use it as a training event as you grow and orient nurses in the long run. Double check or have another nurse check with you on the drips is helpful as well. Do not get discouraged on the med error because it happens to the best of us. Good luck in your career.
