Foundations of Psychiatric-Mental Health Nursing: Comprehensive Study Guide

Foundations of Psychiatric-Mental Health Nursing

  • This curriculum focuses on basic concepts that apply to every mental health disorder studied throughout the course.
  • The core components of psychiatric practice include the psychiatric assessment, the Mental Status Exam (MSE), and identifying clinical cues in patient interactions.
  • The Therapeutic Relationship: This forms the basis of all patient-nurse interactions. It relies on therapeutic communication and specific worksheets/supplemental materials designed to build these skills.
  • The Role of Attitudes: In psychiatry, nurses must "leave their attitude at the door." Failure to do so can jeopardize the safety of the nurse, the patient, and the entire clinical team.
  • Defining Attitude: For the purposes of this course, attitude encompasses self-reflective behaviors, beliefs, and values that influence emotions and the first impressions formed within seconds of meeting a patient.

Self-Awareness and Patient Populations

  • Self-reflection and self-awareness are critical to psychiatric nursing. Nurses must understand how their verbal and non-verbal cues affect patient responses.
  • Challenging Populations: Nurses often face personal biases when working with specific groups, such as:
    • People with drug addictions or substance use disorders (questioning if it is a character flaw versus a brain dysfunction).
    • Homeless individuals.
    • Patients who engage in self-harm (cutting).
    • "Frequent utilizers" of services (patients seen repeatedly, e.g., ten times in three months).
    • Patients experiencing psychosis (hearing voices).
  • The Importance of Efficacy: Nurses should identify which patient populations they work with most effectively. Eliciting positive outcomes builds the nurse's self-esteem and professional confidence.

Implicit Bias and Clinical Perception

  • Implicit Bias Definition: Subconscious stereotypes or biases that affect understanding, actions, and decisions in an unconscious manner. These can be favorable or unfavorable assessments activated involuntarily without intentional control.
  • Perception and Context Examples:
    • Flowers: To some, flowers represent a positive gift. To others, such as the speaker who lost a child at age 2727, pressed and framed flowers represent a source of comfort amidst trauma.
    • Crying Baby: A nurse might wonder, "What can he do to make the baby stop?" while another might ask, "What happened to the baby?"
    • Stereotypes in Media: A reference was made to Jack Nicholson in One Flew Over the Cuckoo's Nest to illustrate historical and media-driven perceptions of psychiatric units.
  • The Dominic Suites: Historically, these were luxury suites in a Richmond hotel/medical setting used for substance use detox and dual diagnosis for high-profile or wealthy patients. The speaker noted that sometimes these high-functioning patients are more difficult to treat than acute patients.

National Association for Mental Illness (NAMI) Statistics 2025

  • Adult Prevalence: 11 in 55 U.S. adults experiences mental illness at some point in their lifetime.
  • Serious Mental Illness (SMI): 11 in 2020 U.S. adults experiences SMI. This includes disorders such as Schizophrenia, Bipolar Disorder, and Major Depressive Disorder, which require medication management.
  • Youth Mental Health: Approximately 70%70\% of youth experience a mental health disorder. Many of these cases are rooted in trauma that leads to physiological brain changes. If untreated, these children often graduate to adult psychiatric units.

The Mental Health Continuum

  • Mental health exists on a spectrum rather than a binary "healthy or ill" state.
  • Mental Health (Well-being): A state where an individual realizes their own potential, uses coping mechanisms to deal with stress, and exhibits resiliency.
  • Maslow’s Hierarchy of Needs: Self-actualization is the peak of the pyramid, built upon physiological needs, safety, and belonging. While total self-actualization is rare, it can be achieved in specific life areas.
  • Mental Illness: Defined by the presence of psychiatric disorders as listed in the DSM-5-TR, characterized by significant dysfunction in behavior or chemical brain function.
  • The Continuum Levels:
    • Occasional to Mild Distress: No significant impairment (e.g., work or school stress).
    • Crisis: Requires intervention to prevent progression to illness. This involves breaking solutions into "smaller chunks" and ensuring support systems (diet, exercise, family) are in place.
    • Physiological Impact: A lack of sleep is a major indicator of decline. Sleep is when the body regulates and repairs itself; its absence leads to physiological deterioration.

Risk Factors and the Diathesis-Stress Model

  • Biologic and Genetic Factors: Many disorders (Bipolar, Schizophrenia, Substance Use) have high heritability.
  • Resilience: This is not always innate; it can be learned through coping mechanisms.
  • Social Determinants of Health (SDOH): Non-medical factors influencing health outcomes, such as the ZIP code of birth, culture, and available resources.
    • Example: A patient in a "food desert" with no transportation may rely solely on a 7-Eleven or Wawa for food. Their diet of "ultra-processed food" increases risks for metabolic syndrome, Type 22 diabetes, and heart disease.
  • The Diathesis-Stress Model:
    • Diathesis: A genetic predisposition or hereditary vulnerability to a disorder.
    • Stress: Environmental triggers, life events, or daily hassles.
    • Mechanism: A person with a high genetic vulnerability (diathesis) may not develop a disorder if their environmental stress remains low. Conversely, high stress can trigger the disorder in those with vulnerability.

Legislation and the Evolution of Care

  • The Genome Project: Mapped the entire human DNA, strengthening the biological basis for identifying the hereditary locus of psychiatric conditions.
  • Affordable Care Act (ACA): Prevented denial of coverage for pre-existing psychiatric conditions and allowed children to remain on parents' insurance until age 2626.
  • Medicaid Expansion: Eligibility varies by state. States that participated in expansion offer a broader spectrum of coverage for mental health and substance use disorders.
  • Quality and Safety Education for Nurses (QSEN): Focuses on nursing education standards (to be discussed further in future lectures).

Technology in Behavioral Health

  • Artificial Intelligence (AI): Used in machine learning and text mining to develop clinical decision support tools.
  • HCA Healthcare: Uses data sent to Nashville to analyze trends, such as the intercom alerts for sepsis developed through this technology.
  • Prescription Digital Therapeutics (PDTs): The FDA has approved 99 PDTs to date. These are app-based tools used to manage cravings in substance use, ADHD, PTSD, chronic insomnia, and anxiety.
  • Social Media and Gaming Addiction: These conditions are being studied for their impact on people skills and the loss of face-to-face interaction.

The Diagnostic and Statistical Manual (DSM-5-TR)

  • This is the current standard for diagnosing mental disorders.
  • DSM-6 Outlook: Future revisions may shift toward "symptom-based" criteria rather than static diagnostic categories, particularly for personality disorders.
  • Classification Categories covered in the course:
    • Schizophrenia and Bipolar Disorders.
    • Depressive and Anxiety Disorders.
    • Obsessive-Compulsive Disorder (OCD).
    • Dissociative and Somatization Disorders.
    • Eating and Substance Use Disorders.
    • Neurodevelopmental and Ped Psych Disorders (e.g., Conduct Disorder).
    • Personality Disorders (often manageable via handouts due to brevity).
    • Medication-Induced Movement Disorders.
    • Suicide and self-harm.

Clinical Practice and Nursing Levels

  • Basic Level RN: RNs working in any specialty or psychiatric-mental health units.
  • Certified RN: Those who have passed the psychiatric-mental health certification exam.
  • Advanced Practice (APRN): Psychiatric Mental Health Nurse Practitioners (PMHNPs).
  • Clinical Units at the Facility:
    • 1st Floor: Adolescent Psych (currently starting at age 1313; younger children go to Virginia Treatment Center for Children).
    • 2nd Floor: Substance Use and Acute Units (Schizophrenia, Bipolar).
    • Geropsych: Elderly patients with psychiatric disorders or those requiring hospital beds for medical-psych dual needs.

Questions & Discussion

  • Student Question (Age): A student asked about working with patients close to their own age. The instructor noted that students just few years older than the adolescent patients can be very effective but must maintain professional boundaries.
  • Student Observation (AI): The class was split (50/5050/50) on whether AI is a positive tool. The instructor emphasized that psych operates in the "gray area" and nurses must be comfortable without black-and-white answers.
  • Academic Integrity Note: The instructor warned that clinical staff use "ChatGPT detectors" for assignments and coursework, advising against using AI to generate "bullshit."
