This systematic review aimed to clarify and define moral sensitivity among nursing students using concept analysis. The study analyzed 38 articles published between 1990 and 2020, focusing on the attributes, antecedents, and consequences of moral sensitivity in nursing students, medical students, and ethics education. The results showed that moral sensitivity in nursing students improves through specialized ethical knowledge and presence in educational and professional settings. Attributes of moral sensitivity include honest and benevolent communication, compassionate professional practice, intuitive perception of moral challenges, awareness of responsibilities and moral consequences of decisions, and the ability to think critically about ethical-legal challenges. Antecedents include specialized-ethical knowledge and presence in professional-educational environments. Consequences include the promotion of quality nursing care and effective management of ethical challenges. The study highlights the importance of moral sensitivity in nursing education and practice, emphasizing the need for further research and the development of appropriate tools to evaluate this concept. Limitations include the focus on Persian and English texts and the inability to access all international databases. The findings contribute to the understanding of moral sensitivity in nursing students and provide a foundation for improving nursing education and ethical practice.This systematic review aimed to clarify and define moral sensitivity among nursing students using concept analysis.
