Ethical considerations
Ethical approval was obtained from the Regional Ethical Review Board of Gothenburg (Dnr 724-10). The Helsinki Declaration (2008) was followed. The permission to conduct research was also given by the director and the head nurse from each department. The nurses were recruited in two different ways: by receiving prior information during a workplace meeting or by being asked to participate the same day of the data collection, on both occasions by the first author. The nurses were informed that their participation was voluntary and confidential. All participants were informed that the NRMP would be video-recorded. Additional information was provided orally and in writing. The first author was waiting for participants on the unit where the nurses worked. This could entail the nurses feeling pressure to participate, when seeing the first author on a few occasions. The potentially negative effect of this was reduced by the first author providing information and requesting their participation on only one occasion, during the same working shift.
