Research suggests that newly graduated nurses lack confidence in caring for deteriorating patients and this lack of confidence could lead to poor patient outcomes. The aim of this project was to examine the effectiveness of a simulation intervention on the confidence level of Associate Degree Nursing (ADN) students in caring for deteriorating patients. The method used was a one group pretest and posttest design. The participants of this project were 11 students in their final semester of an ADN program. These students completed a demographic survey and a pre-test confidence survey. They then participated in the intervention and completed the post-test confidence survey. The project showed an increase in all the five confidence scores questions after the intervention with a p=0.002 for the sum of the confidence scores. An intervention such as the one used in this project may be helpful in increasing confidence and patient care.
