[L.dnurse]

0Hi I'm a new grad en in a major public hospital for 2 mths. Had two days supernumerary. Im on a vascular urology ward with acute surg with a patient load of 5. I'm 35 career change.

i have had a few mistakes. First one was not doing post obs properly that was in my first week. Then after seeing many vac dressings I thought I felt confident in doing one on my own but I chose the wrong dressing. Luckily the dr came to look at the wound and took the dressing down. Third one was removing a skin graft from a forefoot amputation. I looked at it and thought the dressing was still on it. It wasn't until half way through it was bleeding and I thought I've stuffed up. I got called into the office today and I'm on supernumerary for two weeks with some objectives to achieve. I'm so upset with myself. They talk about ask questions and they will help but when I do I feel like they are annoyed at the amount of times I ask questions and think j need to use my brain and try and keep up with the RNs. I'm the only en and have also just completed my IV competency. I work 73hr fortnight. Maybe too much too soon. mow also been told I'm defensive and don't listen. Oh my goodness I'm always helping others and questioning and cleaning up after others and thought I was getting along with my team but apparently someone doesn't think so. I also do not think I know everything infact I feel I know nothing and think that I'm such a bad nurse that I shouldn't be one. I also was told I'm overconfident and too nice. I actual fact I'm rather shy and insecure. I went home after the meeting and not sure how to face tomorrow.
