Trauma, Crisis, Disaster, and Related Disorders: Comprehensive Nursing Study Notes
Learning Objectives and Educational Scope
The study of trauma, crisis, and disaster includes several key learning objectives designed for the nursing level: - Describing the impact of these events on a client’s overall health. - Exploring epidemiological and etiological risk factors contributing to the experience of trauma, crisis, or disaster. - Differentiating the clinical presentations of clients experiencing these conditions. - Exploring the specific role of the nurse when providing care. - Applying the nursing process and clinical judgment functions to clients affected by trauma or crisis.
Overview of Traumatic and Adverse Events
Adverse or traumatic events are categorized into several types: - Natural Disasters: Environmental events such as hurricanes, earthquakes, or floods. - Human-Caused Disasters: Events resulting from human action, including mass violence or industrial accidents. - Specific Experiences: Poverty; racism; discrimination; and oppression.
General Effects and Manifestations of Trauma Exposure: - Intense fear. - Feelings of confusion. - Dissociation (detachment from reality). - Disruptive emotions.
Types of Trauma: - Acute: A single traumatic event that is limited in time. - Chronic: Repeated and prolonged trauma, such as domestic violence or abuse. - Complex: Exposure to multiple traumatic events, often of an invasive, interpersonal nature. - System-Induced: Trauma caused by various systems (e.g., child welfare or legal systems). - Vicarious: Secondary trauma experienced by those who help victims (e.g., healthcare workers). - Historical: Intergenerational trauma experienced by specific cultural or ethnic groups.
Theoretical Framework: Bowlby’s Attachment Theory
Foundational Concepts: Developed by John Bowlby (), this framework focuses on attachment relationships between infants/early children and their primary caregivers (parents).
Necessity: Attachment is viewed as fundamental for survival and healthy brain development.
Stages of Attachment: - Birth to months: Pre-attachment stage. - weeks to months: Indiscriminate attachment. - months to months: Discriminated attachment. - months and beyond: Formation of reciprocal relationships.
The Role of Early Childhood Relationships: - Serve as a protective factor. - Assist in navigating stress and building resilience. - Provide safety and support. - Model positive social-emotional skills. - Aid in responding to needs and developing self-regulation.
Typical Development vs. Developmental Trauma (Visual Model): - Typical Development: Represented as an inverted triangle. The widest part (top) is "cognition," followed by "social/emotional," "regulation," and the narrowest part (bottom) is "survival." - Developmental Trauma: Represented as an upright triangle. The widest part (bottom) is "survival," followed by "regulation," "social/emotional," and the smallest part (top) is "cognition." - This illustrates that in trauma, the brain’s resources are disproportionately focused on survival rather than higher cognition.
Polyvagal Theory and the Autonomic Nervous System (ANS)
Polyvagal Theory: Focuses on the autonomic nervous system's response to trauma using the "Information Superhighway" of the Vagus nerve.
Nervous System Hierarchy in Trauma: - Sympathetic Nervous System: Triggers the Fight-or-Flight response as the initial line of defense. - Dorsal Vagus Nerve: Triggers the Faint-or-Freeze response; a second line of defense involving system shutdown. - Ventral Vagal Nerve: Facilitates Fawn (appeasement) or Social Engagement responses to seek safety.
Physiological Responses of the ANS: - Parasympathetic Nervous System (Rest and Digest): - Constricts pupils. - Stimulates saliva. - Constricts bronchi. - Slows heart rate. - Stimulates production of bile. - Stimulates digestion. - Relaxes intestinal muscles. - Sympathetic Nervous System (Fight or Flight): - Dilates pupils. - Inhibits saliva. - Relaxes bronchi. - Increases heart rate. - Stimulates glucose release. - Inhibits digestion. - Constricts intestinal muscles. - Produces adrenaline.
Pathophysiology and the Impact of Toxic Stress
Types of Stress and Chronic Exposure: - Chronic Exposure: Leads to "Toxic Stress," which normalizes fear and trauma, causing stress-induced chronic changes. - Toxic Stress: Prolonged activation of the stress response that prevents the body and brain from recovering. It occurs primarily when protective factors are missing, leaving the individual feeling exposed, vulnerable, and prone to instability.
The Hypothalamic-Pituitary Axis (HPA): - Acute/Temporary Stress: Triggers hyperarousal but allows the body to return to autonomic equilibrium. - Chronic/Toxic Stress: Results in an ongoing perception of threat, fear, and trauma.
Neuroplasticity and ACEs: - Neuroplasticity: The brain's ability to change in response to trauma and its potential to recover from damage. - Adverse Childhood Experiences (ACEs): These lead to permanent changes in brain structure and alterations in physical and mental health. The ACEs pyramid explores the link between harmful childhood experiences (abuse, neglect, household dysfunction) and outcomes like premature death, economic vulnerability, and chronic illness.
Fear Learning and the Amygdala: - Known as the "brain's fear detection system." - Trauma causes amygdala dysfunction, leading to "fear learning." - This changes nerve pathways, resulting in fear-based emotional responses, fear conditioning, memory consolidation issues, and traumatic re-experiencing.
Manifestations of Toxic Stress
In Children and Adolescents: - Developmental: Delays in reaching milestones. - Behaviors: Engaging in risky behaviors. - Physiological: Increased risk for autoimmune diseases. - Mental Health: Suicide attempts.
In Adults: - Behavioral: Risk of intimate partner violence. - Social: Financial stress or poor work performance. - Physiological: Ischemic heart disease or increased risk for infection. - Mental Health: Substance use, suicide attempts, or depression.
Genetic and Cultural Considerations
Epigenetics: Trauma causes changes in how DNA is translated, affecting nerve and cell development. These changes can be expressed throughout a lifespan and passed to future generations.
Historical Trauma: Described as "soul wounds" on the collective psyche of a population. It is generational trauma from a biological perspective, often seen in vulnerable populations. It results in increased health disparities, mental health stigma, and persistent socioeconomic inequity.
Risk and Protective Factors: - Risk Factors: Family history, existing health concerns, and the experience of traumatic events. - Protective Factors: Secure attachment in childhood, healthy diet/exercise/sleep, positive coping skills, and emotional self-regulation.
PACES: Protective and Compensatory Experiences in Children increase resilience and promote overall mental and physical wellbeing.
DSM-5-TR Trauma- and Stress-Related Disorders
Categories: - Reactive Attachment Disorder (RAD). - Disinhibited Social Engagement Disorder (DSED). - Post-Traumatic Stress Disorder (PTSD). - Acute Stress Disorder (ASD). - Adjustment Disorder (AD). - Other Specified or Unspecified Trauma- and Stressor-Related Disorders.
Prevalence of PTSD/Adjustment Disorder: Highly prevalent in women, adolescents, Black Americans, Hispanic Americans, Indigenous peoples, LGBTQ+ individuals, military members, and first responders.
Shared Characteristics and Timelines: - ASD and PTSD both involve intrusion manifestations and negative alterations in cognition or mood. - Acute Stress Disorder (ASD): Duration of days to month post-trauma. - Post-Traumatic Stress Disorder (PTSD): Duration longer than month.
Age-Specific PTSD Criteria: - Under years: Exposure/witnessing, intrusive manifestations, avoidance, changes in mood, and arousal/reactive manifestations. Children may specifically show "time skew," "omen formation," and "post-traumatic play/re-enactment." - Older than years: Similar criteria but include negative alterations in cognition and mood. Adolescents and adults may experience depersonalization or derealization.
Comorbidities: Bipolar disorder, alcohol use disorder, anxiety, aggression, cardiovascular disease, obesity, and type diabetes mellitus.
Disaster and Crisis Management
Disaster Management Cycle: - Pre-Disaster: Prevention/mitigation and preparedness. - Disaster: The impact of the disaster itself. - Post-Disaster: Response and recovery.
Crisis Emergency Model of Care (Brennaman): - Underlying vulnerability leads to an overwhelmed state lacking control. - Manifestations: Agitation, anger, aggression, feeling "low," anxiety, or euphoria. - Health care provider assessment determines if it is a mental health emergency (requiring emergency intervention) or a non-emergency (requiring crisis intervention).
Age-Related Manifestations After Disaster: - Children: Regression behaviors, sadness, angry outbursts. - Adolescents/Adults: Isolation, withdrawal, depression, anxiety. - All Ages: Eating and sleep disturbances.
Behaviors Requiring Further Assistance: Disorientation, suicidal/homicidal ideation, problematic substance use, or interpersonal violence.
Nursing Role and Trauma-Informed Care
Trauma-Informed Nursing Practice: The goal is to structure care and address needs while avoiding retraumatization. It shifts the question from "Why are you here?" to "What has happened to you?"
Key Principles of Trauma-Informed Care: - Safety. - Trustworthiness and Transparency. - Peer Support. - Collaboration and Mutuality. - Empowerment, Voice, and Choice. - Cultural, Historical, and Gender Issues.
The 4 Cs of Trauma-Informed Care: - Calm. - Contain. - Care. - Cope.
Universal Trauma Precautions: - Take impact of widespread crisis into account. - Use therapeutic communication. - Maintain a judgment-free, healing environment. - Practice self-care.
Bias Management: Addressing both explicit and implicit biases to reduce health disparities and move toward equitable care.
The Nursing Process and Plan of Care
Step 1: Recognizing Cues (Assessment): - Use a trauma-informed perspective to ask "What has happened?" - Document manifestations, life stressors, and functional impairment. - Screening Tools: Not for diagnosis; used to guide treatment and identify risk. Nurses should warn the client of potential discomfort before use.
Step 2: Analyze Cues and Prioritize Hypotheses: - Review symptom domains and evidence of helplessness/hopelessness. - Prioritize by risk: Risk for self-harm, command hallucinations, or risk for other-directed harm.
Step 3: Generating Solutions (Planning) and Taking Actions (Implementation): - Promote safety, collaboration, and coping strategies. - Coordinate medication administration and treatment therapies (e.g., CBT, EMDR).
Step 4: Evaluating Outcomes and Discharge Planning: - Assess client response to the plan of care. - Gather feedback from the interprofessional team.
Prevention Levels in Trauma: - Primordial, Primary, Secondary, and Tertiary preventions.
Therapeutic Modalities and Pharmacology
Cognitive Behavioral Therapy (CBT): Focuses on changing negative thought patterns.
Prolonged Exposure Therapy (PE): Gradual approach to trauma-related memories.
Cognitive Processing Therapy (CPT): Helps clients challenge and modify unhelpful beliefs related to trauma.
Eye Movement Desensitization and Reprocessing (EMDR): Uses bilateral stimulation to process traumatic memories.
Pharmacotherapy: Medication management as part of the interprofessional treatment plan.
