Interview nerves, what actually helps? after 10 years as a nurse's aide

It has been 12 months since my last interview and I feel rusty. I worked as a nurse's aide before this. I want to come across as confident and honest. Any questions to ask at the end?

Thanks for writing this out. I went through something close to it 12 months ago, and it got easier once I kept a simple log of every call and form.
