The ways specialist nursing students understand the work in the ambulance service - a national Swedish phenomenographic study.

This study contributes with a new perspective on supporting role clarity for registered nurses (RN) working in the ambulance service (AS). Specialization and experiential learning are needed to support an understanding of all aspects of the work in order to develop a professional competence aligned with the challenges faced in the AS. The development of expertise in the AS needs a contextualized understanding rooted in a theoretical framework that addresses a holistic perspective towards patients' needs.
