as far as time management, that is learned. To go to another unit or specialty, is going to require retraining and a whole different mindset as far as time and how you prioritize. ICU is stressful! Especially in a big unit with no "warm fuzzy" people like yourself. I get it, Ive been there.
Work on your "brain" the sheet you write all of your things on, use one piece of paper and fold in half. start a system of how to get things checked off. As you begin to understand the flow of the unit from a nursing perspective, you'll begin to piece it together.
If you are on days, maybe nights may suit you better. Ask the advice of those you trust. Identify what takes your time. Is it accuchecks? Entering vitals? Charting your head to toe? Inquire about what works for people. Ask the nurse thats been there 20 years and you'll get an answer. Also ask the one that started last year.
Chart in the room if you can, if you're logged in to give meds, chart your assessment, or your lines, or whatever. Devise a strategy, and make it work.. You will have to revamp, but it will work.
Hang in there. The first year out of school, learning to be a nurse and learning critical care superimposed into that is hard. Don't give up. It gets better.
