Effects of Augmented Reality-based Rapid Blood Transfusion (Level-1®)

The goal of this clinical trial is to compare the effectiveness of AR-based training with traditional guideline-based self-learning in practical nurses without prior Level-1® experience. The main questions it aims to answer are: Does AR-based training using Microsoft HoloLens 2® improve clinical performance compared to traditional guideline-based self-learning? Does AR-based training affect self-efficacy and educational satisfaction compared to traditional methods? Participants will: Receive AR-based training using Microsoft HoloLens 2® (experimental group) Follow traditional guideline-based self-learning (control group) Researchers will compare the AR-based training group to the traditional self-learning group to see if AR-based training leads to better clinical performance, higher self-efficacy, and greater educational satisfaction.
