The aim of this study was to identify nurses' interventions, views, and attitudes concerning critical incidents. Using semi-structured interviews, a descriptive study was conducted among mental health nurses working in three major psychiatric hospitals. Analysis of nurses' audio-recorded data indicated that they had used a number of different interventions under six main categories: counseling, performing security practices, monitoring thinking disturbances, contacting the psychiatrist on-call, contacting the chief nurse on-call, and administering medication. The need for specialized training was noticed and problems like accountability, nurse-patient interactions, and nurse-doctor relationships were considered crucial by the mental health nurses.
