Yesterday while I at work, I had a very strange incidet happen. I was in a patients room about to give her a.m. meds, and we noticed that her water pitcher was empty, so I sat her pills down on her bedside table and was about to go fill her water pitcher when the CNA walked in, at this point the patient asked her will you get me some water please. The CNA said "Yes, but she(me) could have gotten it for you too, we work together around here." I told the CNA that I was about to get it, and she said "Well go ahead, they (patients) try to disinguish between who's what, but we work together around here". I did fill the water pitcher, but I think that situaion could have been handled better. I am a very young nurse and I see this type of attitude aimed towards me a lot from older nurses and cna's. I know I need to work on being more assertive ,but it seems so hard to do at times being a shy person, by being afraid to speak up at times. So suggestions are
