The aim of this study was to elucidate municipal night registered nurses' (RNs) experiences of the meaning of caring in nursing. The research context involved all night duty RNs working in municipal care of older people in a medium-sized municipality located in central Sweden. The meaning of caring in nursing was experienced as: caring for by advocacy, superior responsibility in caring, and consultative nursing service. The municipal night RNs' experience of caring is interpreted as meanings in paradoxes: 'being close at distance', the condition of 'being responsible with insignificant control', and 'being interdependently independent'. The RNs' experience of the meaning of caring involves focusing on the care recipient by advocating their perspectives. The meaning of caring in this context is an endeavour to grasp an overall caring responsibility by responding to vocational and personal demands regarding the issue of being a RN, in guaranteeing ethical, qualitative and competent care for older people.
