BSc Nursing 6th Semester - Mental Health Nursing

ABVMU Examination Notes

UNIT 1: INTRODUCTION TO MENTAL HEALTH NURSING

1. Perspectives of Mental Health and Mental Health Nursing

What is Mental Health? Mental health means a state of well-being where a person:

Realizes their own abilities
Can cope with normal life stresses
Can work productively
Can contribute to their community

Simple definition (WHO): "Mental health is a state of complete physical, mental and social well-being, not merely the absence of disease."

What is Mental Health Nursing? It is a specialized area of nursing that focuses on helping people with mental, emotional, and behavioral disorders. The nurse uses therapeutic communication, empathy, and clinical skills to care for these patients.

2. Evolution of Mental Health Services

Era	What Happened
Ancient times	Mental illness seen as possession by evil spirits; patients were chained or punished
18th century	Philippe Pinel (France) removed chains from mentally ill patients - first reform
19th century	Dorothea Dix (USA) fought for humane treatment in asylums
20th century	Discovery of psychiatric drugs (chlorpromazine, 1952); community mental health movement
Modern era	Deinstitutionalization; outpatient care; rights-based approach

In India:

Mental Health Act 1987 (replaced by Mental Healthcare Act 2017)
National Mental Health Programme (NMHP) 1982
District Mental Health Programme (DMHP) started 1996

3. Mental Health Team (Multidisciplinary Team)

Think of it as a TEAM working together for the patient:

Team Member	Role
Psychiatrist	Medical doctor; diagnoses and prescribes medications
Psychiatric Nurse	Direct patient care, therapy, monitoring
Clinical Psychologist	Psychological testing, psychotherapy
Psychiatric Social Worker	Family support, rehabilitation, community reintegration
Occupational Therapist	Skills training, activity-based therapy
Pharmacist	Medication management
Counselor	Counseling and guidance

Remember: Nurse is the 24-hour link between the patient and all other team members.

4. Nature and Scope of Mental Health Nursing

Nature:

Art and Science of nursing
Involves therapeutic use of self (the nurse uses their own personality as a healing tool)
Requires empathy, patience, non-judgmental attitude

Scope includes:

Inpatient psychiatric units
Community mental health centers
Child and adolescent psychiatry
Geropsychiatry (elderly)
Substance abuse centers
Forensic psychiatry
Consultation-liaison psychiatry (general hospitals)
School mental health programs

5. Role and Functions of Mental Health Nurse

6 Key Roles (easy to remember: CETCCA)

Care Provider - Direct nursing care, monitoring vitals, administering medications
Educator - Teaching patient and family about illness, medications, coping
Therapist - Conducting individual/group therapy sessions
Coordinator - Coordinating with the MDT (multidisciplinary team)
Case Manager - Planning and managing overall care
Advocate - Speaking up for patient's rights

Factors Affecting Level of Practice:

Educational qualification of the nurse
Laws and policies (e.g., Mental Healthcare Act 2017)
Institutional policies
Personal attitude towards mental illness
Community resources available

6. Concepts of Normal vs. Abnormal Behaviour

Normal Behaviour	Abnormal Behaviour
Accepted by society	Violates social norms
Person is self-aware	Poor insight
Causes no distress	Causes significant distress
Adaptive	Maladaptive (cannot function)
Statistically common	Statistically rare

4 D's of Abnormality (easy exam formula):

Deviance - Different from societal norms
Distress - Person suffers
Dysfunction - Cannot carry out daily activities
Danger - Risk to self or others

UNIT 2: PRINCIPLES AND CONCEPTS OF MENTAL HEALTH NURSING

1. Definition and Key Terminology

Important terms to know:

Term	Simple Meaning

2. Classification of Mental Disorders

Three major classification systems:

A. ICD-11 (International Classification of Diseases, 11th Edition)

Published by WHO (World Health Organization)
Used internationally, including India
Key categories for mental disorders: Chapter 06 (Mental, Behavioural or Neurodevelopmental Disorders)

B. DSM-5 (Diagnostic and Statistical Manual of Mental Disorders, 5th Edition)

Published by American Psychiatric Association (APA)
Most widely used in clinical practice and research
Uses categorical diagnoses with specific criteria
No longer uses "axes" (changed from DSM-IV-TR)

Key DSM-5 categories:

Neurodevelopmental Disorders (ADHD, Autism)
Schizophrenia Spectrum Disorders
Depressive Disorders
Anxiety Disorders
Trauma-Related Disorders (PTSD)
Substance Use Disorders
Neurocognitive Disorders (Dementia)

C. Geropsychiatry Manual Classification

Specifically for elderly psychiatric conditions
Focuses on: dementia, delirium, late-onset depression, late-onset schizophrenia

3. Review of Personality Development and Defense Mechanisms

Freud's Stages of Psychosexual Development

Stage	Age	Focus	If Unresolved
Oral	0-1 yr	Mouth, feeding	Dependency, substance abuse
Anal	1-3 yr	Bowel control	OCD, hoarding, stubbornness
Phallic	3-6 yr	Genitals, Oedipus complex	Sexual issues, guilt
Latency	6-12 yr	Social skills	Poor social functioning
Genital	Puberty+	Mature sexuality	Intimacy problems

Erikson's Stages of Psychosocial Development (more important for nursing)

Stage	Age	Crisis	Good Outcome
Infant	0-1	Trust vs. Mistrust	Hope
Toddler	1-3	Autonomy vs. Shame	Will
Pre-school	3-6	Initiative vs. Guilt	Purpose
School age	6-12	Industry vs. Inferiority	Competence
Adolescent	12-20	Identity vs. Role confusion	Fidelity
Young adult	20-40	Intimacy vs. Isolation	Love
Middle adult	40-65	Generativity vs. Stagnation	Care
Old age	65+	Integrity vs. Despair	Wisdom

(Kaplan and Sadock's Synopsis of Psychiatry)

Defense Mechanisms (Freud/Anna Freud)

These are unconscious mental strategies used to protect the mind from anxiety.

Defense Mechanism	Simple Explanation	Example
Repression	Pushing painful memories into unconscious	Forgetting childhood abuse
Denial	Refusing to accept reality	"I don't have a drinking problem"
Projection	Attributing own feelings to others	"He hates me" (you hate him)
Displacement	Redirecting emotions to a safer target	Yelling at family after bad day at work
Rationalization	Making logical excuses for unacceptable behavior	"I failed because the paper was hard"
Regression	Going back to child-like behavior under stress	Adult throwing tantrums
Sublimation	Channeling unacceptable impulses into positive acts	Aggressive person becomes a surgeon
Reaction Formation	Expressing the opposite of true feelings	Hating someone but being very kind to them
Undoing	Performing an act to cancel a bad thought	Washing hands after angry thoughts
Introjection	Adopting values/traits of another	Child adopts parent's values
Identification	Modeling behavior after an admired person	Nursing student copies favorite professor
Intellectualization	Using logic to avoid feelings	Discussing own terminal illness clinically

Mature defenses (healthy): Sublimation, Humor, Altruism, Suppression

(Kaplan and Sadock's Synopsis of Psychiatry - Psychoanalytic Factors)

4. Etiology: Bio-Psycho-Social Factors

Mental illness has THREE types of causes:

A. Biological Factors

Genetics - Family history increases risk
Neurochemical imbalance - Dopamine, Serotonin, GABA, Norepinephrine
Brain structure abnormalities - Enlarged ventricles in schizophrenia
Hormonal factors - Thyroid disorders, postpartum
Infections - Encephalitis, HIV
Head injury

B. Psychological Factors

Early childhood trauma
Attachment problems
Maladaptive thought patterns
Poor coping skills
Low self-esteem
Learned helplessness

C. Social Factors

Poverty and unemployment
Family dysfunction
Substance abuse in family
Domestic violence
Social isolation
Cultural factors
Lack of social support

Key concept: Diathesis-Stress Model = A person has a biological vulnerability (diathesis) + life stress triggers the illness

5. Psychopathology: Brain Structure and Neurotransmission

Key Brain Structures in Mental Illness

Structure	Function	Role in Mental Illness
Frontal lobe	Planning, judgment, personality	Damaged in schizophrenia, dementia
Limbic system	Emotions, memory, motivation	Key in anxiety, depression, PTSD
Hippocampus	Memory formation	Shrinks in depression, PTSD
Amygdala	Fear response	Hyperactive in anxiety disorders
Basal ganglia	Movement, reward	Involved in OCD, Parkinson's
Hypothalamus	Sleep, appetite, libido	Dysregulated in depression

Limbic System (Very Important!)

Called the "emotional brain"
Includes: amygdala, hippocampus, cingulate gyrus, hypothalamus
Controls emotions, behavior, long-term memory
Dysfunction leads to: mood disorders, anxiety, aggression, memory problems

Neurotransmitters and Mental Disorders

Neurotransmitter	Normal Role	Imbalance causes
Dopamine	Reward, motivation, movement	High = Schizophrenia; Low = Depression, Parkinson's
Serotonin	Mood, sleep, appetite	Low = Depression, OCD, anxiety
Norepinephrine	Alertness, arousal	Low = Depression; High = Anxiety, mania
GABA	Inhibition, calming	Low = Anxiety disorders, epilepsy
Acetylcholine	Memory, cognition	Low = Alzheimer's dementia
Glutamate	Excitation, learning	Excess = Schizophrenia, neurotoxicity

6. Principles of Mental Health Nursing

Ten key principles:

Respect for dignity - Every patient deserves respect regardless of their condition
Individualized care - Each patient is unique; tailor care plans
Therapeutic relationship - Foundation of psychiatric nursing
Holistic care - Physical + psychological + social + spiritual
Non-judgmental attitude - Accept patient without criticism
Empathy - Understand patient's feelings without losing objectivity
Confidentiality - Protect patient information
Least restrictive environment - Minimize restraints
Informed consent - Patient must agree to treatment
Continuity of care - Care doesn't stop at discharge; follow-up matters

7. Ethics and Responsibilities

Key ethical principles:

Principle	Meaning	Example
Autonomy	Patient's right to decide	Get consent before ECT
Beneficence	Do good	Give best treatment
Non-maleficence	Do no harm	Avoid unnecessary restraints
Justice	Fair treatment	Equal care regardless of social status
Veracity	Be truthful	Don't lie about diagnosis
Fidelity	Keep promises	Follow through on care plan

Nurse's ethical responsibilities:

Maintain professional boundaries
Report abuse or neglect
Maintain confidentiality (except when patient is a danger to self/others)
Advocate for patient rights
Maintain own mental health (self-care)

8. Practice Standards for Psychiatric Mental Health Nursing (INC)

The Indian Nursing Council (INC) sets standards for psychiatric nursing practice:

Practice is based on current evidence
Nurses must be competent in assessment, diagnosis, planning, implementation, evaluation
Nurses must maintain safe and ethical practice
Continuing education is mandatory
Documentation must be accurate and complete
Nurses must collaborate with the multidisciplinary team

9. Conceptual Models of Mental Health Nursing

A. Psychoanalytic Model (Freud)

Mental illness = unconscious conflicts
Treatment = Psychoanalysis, free association, dream interpretation
Nurse's role: Help patient gain insight into unconscious conflicts

B. Behavioural Model (Watson, Skinner)

Mental illness = maladaptive learned behaviors
Treatment = Behavior modification, CBT (Cognitive Behavior Therapy)
Techniques: Systematic desensitization, token economy, aversion therapy
Nurse's role: Reinforce positive behaviors, extinguish negative ones

C. Existential Model (Frankl, Rogers)

Mental illness = loss of meaning, authenticity, and self-awareness
Treatment = Humanistic therapy; help person find meaning and purpose
Nurse's role: Non-judgmental presence, unconditional positive regard

D. Interpersonal Model (Hildegard Peplau - Most Important for Nurses!)

Peplau's Theory - the most influential nursing theory in psychiatry
Mental illness = problems in interpersonal relationships
Treatment = Therapeutic nurse-patient relationship
Peplau's 4 Phases of Nurse-Patient Relationship:
1. Orientation - Patient identifies needs; nurse assesses
2. Identification - Patient identifies with nurse
3. Exploitation - Patient uses nursing services to full advantage
4. Resolution - Goals met; relationship ends professionally

Peplau's roles of the nurse: Stranger, Resource person, Teacher, Leader, Surrogate, Counselor

10. Preventive Psychiatry and Rehabilitation

Based on Caplan's Model of Prevention:

Level	What it means	Examples
Primary Prevention	Prevent illness from occurring	Mental health education, stress management programs
Secondary Prevention	Early detection and treatment	Crisis intervention, early diagnosis
Tertiary Prevention	Reduce disability; rehabilitation	Vocational training, halfway homes, day care centers

Rehabilitation components:

Medical rehabilitation - Medication management
Psychological rehabilitation - Psychotherapy, counseling
Social rehabilitation - Family therapy, social skills training
Vocational rehabilitation - Job skills, employment support

QUICK REVISION - KEY POINTS FOR EXAM

Important Dates/Names to Remember:

Philippe Pinel - Removed chains from mentally ill (France, 1793)
Dorothea Dix - Asylum reform movement (USA)
Hildegard Peplau - "Mother of Psychiatric Nursing"
Sigmund Freud - Psychoanalysis, defense mechanisms
Erik Erikson - 8 stages of psychosocial development
INC - Sets nursing practice standards in India
NMHP - National Mental Health Programme, India, 1982

Neurotransmitter Memory Trick:

"SAD" = Serotonin low → Depression (Sad mood)
"Dopamine Drama" = Too much → Schizophrenia (dramatic behavior); Too little → Parkinson's/Depression
"GABA calms" = GABA is the brake pedal of the brain

The 4 D's of Abnormal Behaviour:

Deviance + Distress + Dysfunction + Danger

Peplau's 4 Phases: "O I E R"

Orientation → Identification → Exploitation → Resolution
