when i was a relatively new nurse and on the night shift, there was a patient who was uncooperative. a med student came in to draw blood on her and i was there to assist, i was shocked when i saw the med student hit the patient, and the patient started crying telling her to stop hitting her. i am a very quiet person, but i was outraged and immediately called the supervisor. the med students story was that the patient was about to bite me, but i was watching her and i know that was a lie. the following morning i had to meet with the vice president of nursing as well as the chief of medicine. not suprisingly, the med student was barely reprimanded and i was made to feel as if i was in the wrong for reporting it. I have never been as proud of myself as i did that night for standing up for that patient. i cant tell you what to do, but in your heart you know if what the co worker did was wrong. good luck
