How much research does a CNS do?

I like research...it satisfies my creative side. I like reading and writing too. And I've been looking at nursing roles that satisfy those likes.

I know nursing faculty do plenty of research, especially the PhD types, and they're in great need. But I also know they're not paid well, which could be a problem.

I've also heard that a CNS does research as well. I was wondering, how much of their job is research?

Thanks
