All the very best nurses I know, never stop asking questions. Don't define yourself by your answers, but by your questions.
The other attribute I have seen all the best nurses possess is the ability to say these 3 words: "I need help". That will be the fastest way to go from novice to competent to mastery that there is. There is not one expert nurse that I know who doesn't access and fully exploit every resource available. From IV resource, to Respiratory, to Pharmacy, to the Housekeepers....the very best of us, know how to develop relationships and use their expertise for the best treatment of their patients. A lot of new nurses think that the goal is the be self-sufficient, but that is only a small part of competence, the far bigger component of competence is using all the resources that you can. Also, you need to know when you are not going to be able to complete something on your shift, and to set it up in a way that the next shift can take it over. Nursing is 24 hours, you don't have to do it all in your 8 hour shift (or 12).
Use this time to develop some routines. Learn how to do assessments systematically and fast. Develop for yourself what works, perhaps have a check list for yourself. One thing that took me the longest time to remember to check right away were my IV sites and if the patient had a foley, what did the urine look like. I was in the middle of charting my assessment and I would have to get up and go back in and check those things. Drove me nuts!! I set up a list for myself and I would keep it in my pocket and glance at it and it really helped with my efficiency.
Be very patient with yourself. If your patient asks you something and you don't know, just say, I'm not sure about that, but I will look it up for you. It is OK. Patients are looking to you as someone who they can trust and confide in, not someone with a Doctor's knowledge. Be the advocate, not the expert. I never attempt to come across as an expert, but I definitely attempt to come across as concerned and committed to doing all that I can for that patient, including comfort and healing and that the Docs orders are carried out.
That is a very good question, by the way. Remember we are defined far more by our questions, than by our answers. You are well on your way ......
