CINAHL is the best database ACC provides for identifying nursing articles. You may find nursing research articles using some of the other health science article databases, such as Health Source Nursing/Academic Edition and Health Reference Center - Academic, but CINAHL offers a level of searching focus that is unique.
Enter your search terms at the top (influenza is used in the example below)
Below the search box, you will will see the following ways to limit your results. If you make sure that the sections marked in red are set similarly in your search, you will ensure that your search will focus on peer-reviewed nursing research articles that have the full-text of the article available to you online. Of course, you can change any of these limiters to suit your needs -- this example just shows how to get started. Once you've got your term entered and your settings complete, click the search button at either the top or the bottom of the screen.
