I think you will find that many nursing students have had this experience. You are not alone. (I did not really get to experience IV Meds until I worked on a Med Surg Unit.) Do not let the treatment you receive as a student determine your future.
You, too, will get plenty of opportunity to do IV's and Piggy backs, and IV Push meds as a nurse on the floor.
Just be proactive with your preceptorship and make sure your preceptor is someone you are comfortable with. If you are not comfortable with your preceptor go talk to the Director of Nursing and ask her/him if they can reassign you to a new preceptor.
Whatever you do do not allow anyone to bully you or make you feel bad.
As a new nurse you hold as much value to the profession as do more experienced nurses.
Right now, don't worry too much about your first work experience and put the treatment you have received in the past behind you. The only thing you should be worrying about right now is moving forward, because it is the only way to move.
When you do become a nurse and have students on your floor remember how it felt when no one had the time to take a moment to pass their valuable knowledge and experience to you and don't repeat that mistake.
I know there are days when I feel like I just don't have enough time to do it all but I always try to include students when I am doing something I think might be of interest to them. Simply because I do remember the nurse who looked at me and made a snotty remark when I asked her to show me how to do something. Also, you might want to gleen info from any LPN's you come into contact with. I found the LPN's more willing to help and teach than the RN's most of the time. Go figure.
I love being an RN but we are a funny group of people.
The nursing profession will be what we make it. It can be a supportive place that grows through welcoming, supporting and encouraging its young or it can be a profession that dies out because we "eat our young". The choice is ours as RN's.
Much luck to you in the future and I hope you have a long and rewarding career.
