Trauma leading to severe bleeding is one of the reasons for the high mortality rate in trauma patients, resulting in multiple and complex injuries from various accidental mechanisms. However, patients with abdominal-pelvic trauma accidents rank among the top three common accidents in the emergency department. There is a potential for both trauma and severe internal bleeding, making the care of such patients even more challenging. Currently, trauma nursing education focuses on emergency medical care, and teaching on the care of abdominal-pelvic trauma occupies only a small part of the entire nursing curriculum.

In addition to insufficient knowledge teaching in emergency trauma medical care, learning relies heavily on the arrangement of clinical internships, and obtaining practical experience in the care of abdominal-pelvic trauma is often difficult. In the current era of thriving digital learning, allowing learning to be more diverse and unrestricted by time and location, it is essential to integrate appropriate guiding strategies alongside digital technology to make learning more efficient and promote meaningful learning.

Therefore, this study introduces decision trees into an interactive scenario-based learning environment for the care of severe bleeding due to abdominal-pelvic trauma. The decision tree is coupled with a decision-making strategy, utilizing the relationships between leaf nodes to guide learners in clarifying their misconceptions, ultimately leading them to make appropriate decisions to reach the final nodes and solve problems.

To understand the effectiveness of this study, a real experimental research design is adopted to investigate the impact of introducing decision tree-based interactive teaching materials on the care of severe bleeding in abdominal-pelvic trauma situations on the professional knowledge, self-efficacy, clinical reasoning assessment ability, and technology acceptance of surgical nursing students over a two-year period. It is hoped that this interactive teaching material for the care of severe bleeding in abdominal-pelvic trauma scenarios will enhance learners' professional knowledge, self-efficacy, clinical reasoning assessment, and technology acceptanc.
