Q. I need scholary nursing articles from 2012 to 2017 on Debriefing and nursing students

Your best strategy is to start off on the advanced search option of databases available  where you can add debriefing in one field, "nursing student" in another (with quotes), then add the year limits and select scholarly/peer reviewed articles. 

I actually tried several databases and the best options were available from from EBSCO Nursing databases (which incudes CINAHL) and Gale PowerSearch. You can access them both the the A-Z databases: Nursing page (link below).

These both search multiple databases which can really help when you aren't finding enough articles on a topic. I got the most from Gale. You'll still need to review the articles on the result list to see what works best for your assignment.
