Mental Health Nursing
Roles, Functions & Practice Factors
Comprehensive guide for nursing students on the roles and functions of mental health nurses across various settings, and the factors that influence the level of nursing practice.
Introduction to Mental Health Nursing
“Every day that you bring your skills, your knowledge, your empathy, and an open mind, you will make a difference in a patient’s life.”
— Kristen Kichefski, MSN, MBA, RN-BC
Mental health nursing, also known as psychiatric-mental health nursing, is a specialized area of nursing practice that focuses on promoting mental health, preventing mental illness, and caring for people of all ages experiencing mental health challenges.
Psychiatric-Mental Health (PMH) registered nurses (RN) and advanced practice registered nurses (APRN) represent the second largest group of behavioral health professionals in the U.S. They work in a variety of settings and provide comprehensive care to individuals, families, groups, and communities.
Mental health nurses form therapeutic relationships with patients across the lifespan to understand their unique stories and challenges, with the goal of transforming lives in a positive way through evidence-based interventions.
Key Distinction
Mental health nurses are distinguished from other mental health professionals by their focus on exploring environmental factors that influence mental health and assisting people in building stronger interpersonal relationships.
