The purpose of this study is to determine how closely student nurses' perceptions of their clinical judgment skills match their demonstrated clinical judgment skills when participating in a simulated clinical situation. The evidence suggests there are disparities in the student nurses' ability to make accurate and timely clinical judgments, along with the lack of recognition that the judgments were incomplete or incorrect. I will begin this research study on November 15, 2012 using the undergraduate nursing students in my junior level Adult Illness nursing courses in the fall and winter semesters. I believe the results of this study will be ground breaking, regardless of the findings because of the lack of research in this area. The problem is apparent, but there is a lack of solid evidence to clearly identify the salient issues, It is imperative that nursing faculty become aware of the issues surrounding student nurse self perception of performance, as it compares to their actual abilities, in order to develop appropriate methods to assess, evaluate, and eliminate any inequities discovered. The Lecturer's Professional Development Fund monies would allow me the opportunity to disseminate the findings of this study to nursing faculty at a large national conference. The Drexel Nursing Education Institute is a heavily attended conference that focuses on research and innovation in nursing education. The conference in 2013 will be held on June 18 through June 21 in New Orleans, Louisiana. I will be submitting an abstract for consideration for a podium presentation at this conference.
