Many hospitals have been promoting research among their nursing staff. A nurse can serve as a researcher in many ways.
Because nurses are on the front lines of patient care, they often see first hand which methods work best for patients. They are able to access patient records and monitor patients' progress.
When conducting research, nurses choose a particular area on which to focus. They then collect data and draw conclusions based on statistically valid results. Those results are then reported to the organization where they work, to national associations, or even in journals.
