In the process of preventing, treating and caring for pressure ulcers, nurses take on an important responsibility and are one of the most common adverse events during hospitalizations worldwide. Pressure ulcers, which are a serious problem especially in cases requiring long-term care. These ulcers occur as a result of prolonged exposure of soft tissues to pressure and can lead to local tissue damage, carrying the risk of infection. In Turkey, pressure ulcers are considered an indicator of patient care quality for healthcare institutions, and many healthcare institutions continue their efforts to reduce the rate of pressure ulcers.

Moulage-supported education provides appropriate care that increases the quality of care. Therefore, it is critical for nurses to develop pressure injury assessment skills before and after graduation. However, in clinical settings, there are challenges such as limited opportunities for developing psychomotor skills, increasing student numbers, complexity of the healthcare system, and patient safety issues. In response to these challenges, the importance of simulation-based education that provides practices similar to clinical experience has emerged. Moulage plays an important role in high-quality simulations that appeal to many senses. Moulage can be defined as the application of make-up or other elements to add realism to simulation training by creating realistic-looking wounds. The use of moulage provides a valuable opportunity for practical experience that can be perceived by many senses such as vision, hearing and touch. The use of moulage helps students understand the etiology, physiology and healing processes of the wound and is an effective tool for developing wound assessment skills.

Simulated patients, known as standardized patients, which have recently emerged, are used to promote performance, competence and knowledge development among nursing students. Standardized patients help students improve their clinical and speaking performances by providing them with the opportunity to realistically play the role of a patient with a health problem.

Evaluating nursing students' perceptions and thoughts about clinical practice and their self-efficacy perceptions can contribute to the development of more effective strategies by evaluating the effectiveness of clinical practice strategies.

No research has been found on the effect of the use of moulage-supported standardized patient simulation on nursing students' self-efficacy and clinical practice attitudes towards pressure ulcers. This study is planned to be conducted as an experimental study to investigate the effect of the use of moulage-supported standardized patient simulation on nursing students' self-efficacy and clinical practice attitudes towards pressure ulcers.
