Aims: This study aimed to explore how emergency nurses understand and perform their professional roles and practice during epidemics. Methods: A qualitative descriptive study design was used. Data were collected from 24 participants through semistructured interviews and subjected to thematic analysis. Findings: The analysis yielded two overarching themes: expansion in the practice of emergency care; and the altered role of emergency nurses. Conclusion: Emergency nurses perceive their practice during the management of an epidemic expanded in that they shouldered a greater responsibility in the control of infectious diseases. This expansion led to role ambiguity among them.enjournal article10.12968/bjon.2019.28.8.523
