Nurses in this area receive specific training in psychological therapies, building a therapeutic alliance, dealing with challenging behavior, and the administration of psychiatric medication. In most countries, a psychiatric nurse will have to have attained a bachelor's degree in nursing to become a registered nurse (RN) and specialize in mental health. Degrees vary in different countries and are governed by country-specific regulations. Psychiatric nurses work in hospitals, mental institutes, correctional institutes, and many other facilities.
