First of all, after the theoretical course of parenteral drug administration was explained to the students in the control and experimental groups by the researchers, the course was applied on model patients in the skill laboratory of the faculty. Then, the knowledge and skills of both the experimental and control groups were measured. The knowledge of the students was measured by the knowledge test prepared by the researchers. The skills of the students were evaluated with the OSCE exam by using a checklist by instructors other than the researchers. Afterwards, the 'escape room' game was played by the researchers in the skill laboratory of the faculty with the experimental group. The control group, on the other hand, was given the right to work independently in the faculty's skill laboratory to perform the skills related to the subject. After the game, the knowledge and skills of both the experimental and control groups were measured again. The knowledge of the students was measured by the knowledge test prepared by the researchers. The skills of the students were evaluated with the OSCE exam by using a checklist by instructors other than the researchers. The game was played once with the experimental group. For the game, the experimental group (36) was divided into 9 groups of 4 people each. In the game, each student was expected to perform the related skill of the patient (model patient) in the related patient room in the skill laboratory, and to perform the activities (puzzle, puzzle, etc.) in the patient rooms together as a group.

Escape room game is a type of social game that requires groups of four to ten people to work together based on solving a series of puzzles to escape from a locked room. Although the escape room game is a social game, it has been used in education and training in the last few years. The game features puzzles that students must solve in a limited time to open the box by placing a set of locks on a closed box. Participants work together to find and solve clues around the room to unlock each of the locks.

Preparation of the escape room:

Gazi University Faculty of Health Sciences nursing basics skills laboratory has been transformed into an escape room. In order for the first year students to gain knowledge and skills about parenteral drug applications and reach their learning goals, four patient rooms in which parenteral drug administration skills are practiced in clinical order were created in the skill laboratory and made ready for the escape room game. In order for students to perform activities and skills related to the subject; locked chest box, number coded chest lock, stopwatch, blackboard, whistle, materials to be used in puzzle making, colored paper and cardboard, etc., on which activity questions are processed. Along with the materials, the medical materials (injector, sharps-drilling waste box, cotton, gloves, etc.) that the students will use while performing their parenteral drug administration skills were provided by the researchers.

In each patient room, model patient, patient bed, arm-hip model, bedside unit, bedside table, bedside table; nurse file and related activities developed by the researchers were placed. Curtains and screens were used to separate each patient bed from each other in order to create a patient room layout. The treatment car, which will be used to prepare the treatment of the patients, was placed in an area suitable for the skill laboratory by placing the necessary materials inside. In addition, a locked box and a whiteboard were placed in a suitable area in the middle of the skills lab. In this way, a clinical environment was created and the escape room was made ready. Escape room game rules were created by the researchers in order to determine the game limits and for the participants to understand the game easily.
