Introduction to Mental Health and Nursing

Mental health encompasses our emotional, psychological, and social well-being. It affects how we think, feel, and act. Mental health is a state of well-being in which every individual realizes his or her own potential, can cope with the normal stresses of life, can work productively and fruitfully, and is able to make a contribution to her or his community. Mental illness, conversely, refers to conditions that affect a person's thinking, feeling, or behavior, leading to distress or functional impairment. These conditions can range from mild to severe and can impact various aspects of a person's life, including relationships, work, and daily activities. Examples include depression, anxiety disorders, and schizophrenia. Behavioral disorders are conditions marked by patterns of disruptive behavior. These often manifest in childhood and adolescence, such as conduct disorder or oppositional defiant disorder. It is important to emphasize that mental illness is not a sign of personal weakness. It is a treatable medical condition, just like physical illness. For example, a person experiencing major depressive disorder can experience symptoms of sadness, loss of interest, and fatigue. A person experiencing a behavioral disorder, such as conduct disorder, may demonstrate aggression and disregard for rules.

Historically, the treatment of mental illness has varied dramatically. Early approaches often involved asylums, which provided custodial care but often lacked effective treatments and sometimes involved inhumane practices. The 18th and 19th centuries saw some reforms, with a shift towards more humane treatment. This includes the moral treatment movement. In the 20th century, the advent of psychoanalysis and psychopharmacology (medications) revolutionized treatment. Deinstitutionalization, a significant movement, led to the closure of many asylums, with the aim of integrating individuals back into the community, but created many challenges. Today, mental healthcare emphasizes a biopsychosocial approach, considering biological, psychological, and social factors in treatment. This approach emphasizes patient-centered care, evidence-based practices, and the importance of multidisciplinary teams. These teams include nurses, psychiatrists, psychologists, social workers, and other professionals who work together to provide comprehensive care.

Registered Nurses are integral to the mental healthcare team. They provide direct patient care, including medication administration, assessment, and therapeutic communication. The RN assesses a patient's mental status, monitors their physical and emotional well-being, and collaborates with the healthcare team to develop and implement care plans. They also educate patients and their families about mental health conditions, medications, and coping strategies. Furthermore, RNs advocate for their patients and ensure they receive quality care. Examples of nursing interventions include assessing a patient’s suicide risk, providing a safe and supportive environment, administering medications, and teaching coping mechanisms such as deep breathing exercises.

The scope of practice for RNs in mental health is determined by the Nurse Practice Act of the state in which they are licensed. In general, RNs in mental health can perform assessments, develop care plans, administer medications, provide individual and group therapy (often under supervision), and educate patients and families. They can also participate in crisis intervention, provide support, and coordinate care with other members of the healthcare team. The specifics may vary from state to state, so it’s crucial for nurses to be aware of their state's regulations. For example, RNs may not be able to independently diagnose mental illnesses, but they can gather information through assessment and contribute to the diagnostic process by reporting their findings to the psychiatrist or other mental health professionals.
