The aim of the present study was to describe how registered nurses in nursing homes ensure legal security, good and safe nursing care and uphold the dignity of nursing home residents with severe dementia without violating residents' integrity. Semi-structured interviews were conducted with 10 charge nurses in a county in central Sweden. The transcribed interviews were examined using manifest and latent content analyses. The manifest analysis identified actual local routines involving coercive treatment and registered nurses' descriptions of complications and alternative measures. The latent analysis resulted in three themes describing nursing strategies: one with coercive treatment, one with coercive treatment under specific circumstances and one to prevent coercive treatment. Interpretations of legal terms regarding coercive treatment and inadequate gerontological nursing training and understaffing seem to preserve the use of coercive treatment.
