Mental health nursing, often known as psychiatric nursing, is a specialist branch of nursing that focuses on providing care to people who are suffering from mental disorders in order to help them recover and enhance their quality of life. Mental health nurses have advanced knowledge of psychiatric disorders' assessment, diagnosis, and treatment, which allows them to provide specialized care. They usually work as a medical team with other health experts in order to provide the best clinical outcomes for the patient. Individuals of any age, ethnicity, or socioeconomic level can be affected by mental illness. As a result, a mental health nurse may be required to work with a wide range of people from various backgrounds. A mental health nurse's primary responsibility is to care for patients who have psychiatric disorders, mental health issues, or behavioural issues. A mental health nurse’s responsibility is similar to those of a psychiatrist, and includes diagnosis, treatment, and drug prescription.
