The aim of the study was to identify nurses’ ethical values, which become apparent through their behaviour in the interactions with older patients in caring encounters at a geriatric clinic. Descriptions of ethics in a caring practice are a problem since they are vague compared with the four principles of autonomy, beneficence, non-maleficence, and justice. A Grounded Theory methodology was used. In total, 65 observations and follow-up interviews with 20 nurses were conducted, and data were analysed by constant comparative analysis. Three categories were identified: showing consideration, connecting, and caring for. These categories formed the basis of the core category: ‘‘Corroborating.’’ In corroborating, the focus is on the person in need of integrity and self-determination; that is, the autonomy principle. A similar concept was earlier described in regard to confirming. Corroborating deals more with support and interaction. It is not enough to be kind and show consideration (i.e., to benefit someone); nurses must also connect and care for the older person (i.e., demonstrate non-maleficence) in order to corroborate that person. The findings of this study can improve the ethics of nursing care. There is a need for research on development of a high standard of nursing care to corroborate the older patients in order to maintain their autonomy, beneficence, and nonmaleficence. The principal of justice was not specifically identified as a visible nursing action. However, all older patients received treatment, care, and reception in an equivalent manner.
