In the current healthcare environment, nurses are required to provide timely and competent responses to rapidly changing demands resulting from an increasingly expanding wealth of medical knowledge. High fidelity simulation offers unlimited opportunities to practice rare and critical events in a safe and controlled environment.Literature supports the use of simulation for the acquisition of nursing knowledge and skills. However, findings based on the students' perceptions of satisfaction and selfconfidence after these simulated experiences is inconclusive. The purpose of this descriptive study is to describe BSN students' perceptions of satisfaction and selfconfidence after a simulated mock code experience and to determine the relationship between the students' perceptions of satisfaction/self-confidence and the demographic characteristics. A convenience sample of 50 senior BSN students who were enrolled in a senior-level nursing Leadership and Management course was included in the study. The participants completed a paper-and-pencil five-point Likert scale Student Satisfaction and Self-Confidence in Learning (National League for Nursing, 2004) survey after the simulated mock code experiences. The results indicated that students were satisfied with the mock code simulation (mean=4.49, SD=0.53) and felt confident with code situations after the simulated experience (mean=4.42, SD=0.41). A significant correlation was found between the male students and satisfaction scores. Independent t-tests did not reveal significant differences between satisfaction/self-confidence and past experience as healthcare providers. However, previous experience working as an EMT was found to significantly contribute to a high level of self-confidence after simulated mock code experiences. The findings of this study provide insight into students' perceptions of self-confidence and v satisfaction toward simulation and may assist faculty to appropriately integrate simulation into nursing curriculums.
