The students in the experimental group were shared the digital stories prepared for drug applications from the WhatsApp group and were asked to watch them for two weeks. Students were able to watch the stories on their mobile phones at the time and frequency they wanted. During 2 weeks, the researchers met with the students twice in the classroom environment and received feedback on the digital stories. Feedbacks about the real meaning of the stories and their contribution to education were obtained by using discussion and question-answer methods. Each student explained their opinions about the stories and had the opportunity to think deeply about them by receiving feedback from their classmates.

For the pre-test data, 'Individual Introduction Form' and 'Medical Error Tendency Scale' were given to the students and they were asked to fill them in.

At the end of 2 weeks, the 'Medical Error Tendency Scale' was applied again at the end of the 2nd week to see the change in the medical error tendency levels of the students who were trained with digital stories teaching method for 2 weeks. Medical Error Tendency Scale: It was developed by Özata and Altunkan to measure the medical error tendencies of nurses. The scale consists of 49 items and 5 different sub-dimensions, and the sub-dimension used in this study, the sub-dimension of medication and transfusion practices, consists of 18 items. The higher the mean score of the scale, the lower the tendency of nurses to make medical errors.

Safe Parenteral Drug Administration Self-Efficacy Scale: The scale developed to determine the self-efficacy of nurses regarding parenteral drug administration consists of 76 items and one dimension. The scale is a 5-point Likert-type scale and 1: Completely disagree, 2: Disagree, 3: Undecided, 4: Agree, 5: Strongly agree. A minimum score of 76 and a maximum score of 380 can be obtained from the scale. The higher the score obtained from the scale, the higher the self-efficacy of nurses regarding safe parenteral drug administration.
