You can definitely be a nurse! Your introverted traits can definitely serve you well, but some may get you into trouble at times, so you need to watch certain things. Introverts tend to do very well in one on one situations, so you should do quite well with your one to one patient care. You may need to be more watchful of your interaction with your colleagues. As an introvert myself, I remember a time when I got written up for not spending enough time at the nurses station with other nurses. As introverts we tend to avoid small talk. I cannot stand gossip and do not understand small talk at all. I do not talk on the phone unless there is a good reason...etc etc. Well my wonderful nurse friends at the station reported me for spending too much time with my patients. Go figure.
