Aim: This study was conducted to determine the nurses' perception of patient safety and the strengths and weaknesses they encounter in providing patient safety by using the experiences of nurses.

Material and Methods: In the study, phenomenological design, one of the qualitative research methods, was used. Semi-structured interview technique was used in the study. The research study group was determined by the purposive sampling method, one of the improbable methods. The sample comprises 45 volunteer nurses working in a private and a university hospital.

Results: In the interviews, nurses expressed patient safety as not harming the patient in general, while they expressed the patient safety culture as the attitudes, behaviors, and values displayed by the employees to ensure patient safety. In addition, nurses stated that human and environmental factors affect patient safety and how they manage safety risks in ensuring patient safety. In this context, as a result of the interviews, five main themes "Known about Patient Safety and Patient Safety Culture", "Factors Violating Patient Safety", "Risk Management in Ensuring Patient Safety", "Teamwork in Ensuring Patient Safety - The Importance of Communication", "Providing Continuous Education and Interaction in Sustaining Patient Safety" and thirteen sub-themes were created.

Conclusion: As a result of the study, it was seen that nurses were aware of patient safety but not as much awareness of patient safety culture as patient safety. In the study, it was determined that ensuring patient safety, providing regular control in patient care and treatment, paying attention, doing everything right, taking precautions, teamwork, continuous education, and interaction are strengths, while errors caused by human and environmental factors, insufficient number of personnel and excessive workload are weaknesses. Hospital administrators and executive nurses should support and develop nurses to develop nurses' patient safety culture. In addition, nurses should be provided with training for developing patient safety culture and patient safety competencies should be increased by considering their views on safety practices.
