I. Learning Objectives & Foundations

By the end of this module, the nursing student should be able to:

  • Recognize Cues: Identify physiological and psychological manifestations across the mental health continuum.
  • Prioritize Care: Implement immediate nursing actions based on the client's level of anxiety.
  • Pharmacological Safety: Recall key medication classes, side effects, and life-threatening complications like Serotonin Syndrome.
  • Trauma-Informed Care: Differentiate between Adverse Childhood Experiences (ACES) and Positive Childhood Experiences (PCEs).

The Pathophysiology of Anxiety

Anxiety is a normal response to stress that becomes a disorder when it interferes with daily functioning, is out of proportion to the trigger, or is prolonged.

II. The Stress Response & Risk Factors

Understanding how the body responds to stress is foundational for psychiatric nursing.

General Adaptation Syndrome (GAS)

  1. Alarm Phase: The "Fight, Flight, Freeze, or Fawn" response; adrenal glands release cortisol, leading to an increased heart rate.
    • This phase signifies immediate reaction to a stressor.
  2. Resistance Stage: The body attempts to stabilize and repair itself; the autonomic nervous system begins to downregulate but remains heightened in response to stress.
  3. Exhaustion Phase: Energy reserves are depleted; the body is unable to self-regulate, and anxiety can become a chronic disorder.
    • This stage signifies prolonged exposure to stress without adequate coping mechanisms.

Etiology & Risk Factors

Mental health disorders often follow the Diathesis-Stress Model, where an underlying vulnerability meets an environmental trigger.

  • Genetic: Adult-onset OCD in a family member doubles the risk of developing similar conditions; childhood-onset increases it tenfold.
  • Neurobiological:
    • The Cortico-striato-thalamo-cortical circuit is associated with worry and obsessions.
    • The Amygdala-centered circuit is linked to fear and panic responses.
  • Temperamental: Traits such as shyness, behavioral inhibition, or avoidance are significant risk factors for anxiety disorders.
  • Modifiable Factors: Diet, exercise, and substance use (e.g., tobacco) can influence the severity of these manifestations.

III. Levels of Anxiety: Assessment & Interventions

ATI often uses a speedometer analogy to describe these levels. Nurses must tailor interventions based on where the client falls on the Mental Health Continuum.

LevelCharacteristics & CuesPriority Nursing Interventions
MildSharpened senses, restlessness, finger tapping/nail-biting.Assist in problem-solving and use of coping mechanisms.
ModerateNarrowed perceptual field, selective inattention, physical symptoms like dry mouth, frequent urination, or insomnia.Use a calm manner and low voice; provide simple, structured instructions. Do not force decisions.
SevereSense of "impending doom," tachycardia, inability to problem-solve. Client may act out.Stay with the client; focus on immediate physical needs: fluids, blankets for warmth, and rest to prevent exhaustion.
PanicDisorganized behavior, detached from reality, dilated pupils, hallucinations. No longer responding to stimuli.Safety is the #1 priority. Minimize stimuli (move to seclusion if needed); stay with the client and use a quiet environment.
Critical Note

During severe to panic-level anxiety, avoid "reality checks" or long explanations; the client's cognitive ability is too impaired.

IV. Specific Disorders & Clinical Cues

1. Anxiety Disorders

  • Generalized Anxiety Disorder (GAD): Excessive worry for 6 months or more.
    Mnemonic: "AND IC REST" (Anxious, No control, Duration, Irritability, Concentration, Restlessness, Energy low, Sleep changes, Tension).
  • Phobias: Intense fear of specific objects; therapy of choice is Systematic Desensitization (gradual exposure).
  • Social Anxiety Disorder: Fear of being in groups or concerns about others' opinions (e.g., clothing choices).

2. Obsessive-Compulsive & Related Disorders

  • Obsessive-Compulsive Disorder (OCD): Driven by obsessions (recurrent intrusive thoughts) and compulsions (repetitive behaviors performed to lessen anxiety).
    • Compulsion Examples: Constant finger motion, seating a chair at a precise angle, tying/retying shoes for alignment.
    • Intervention: Initially, do not prevent rituals. Empathize with the client's need and provide private time for these actions.
  • Body Dysmorphic Disorder (BDD): Imagined or slight physical defects; surgical correction does not solve the underlying distress.
  • Hoarding Disorder: Chronic inability to discard items; typically debilitating and has a late onset.
Mnemonic for Panic Attack Symptoms

"STUDENTS FEAR the 3 Cs"

  • Symptoms: Sweating, Trembling, Unsteadiness, Derealization, Elevated HR, Nausea, Tingling, Shortness of breath, FEAR of dying/losing control.
  • 3 Cs: Choking, Chest pain, Chills.

V. Nursing Pharmacology

Drug ClassExamplesKey Nursing Considerations & Teaching
SSRIsSertraline, Fluoxetine, EscitalopramDelayed onset (2-4 weeks); take in the morning to avoid insomnia; do not stop abruptly; monitor for hypertension and anorexia (weight loss); take with food to reduce nausea.
SNRIsVenlafaxine, DuloxetineSame as above for SSRIs with some adjustments based on patient response.
BenzodiazepinesAlprazolam, LorazepamFast-acting (relief in 30-60 mins); high risk for dependency and abuse; antidote is Flumazenil.
BuspironeBusparNon-sedating, non-addictive; takes 1-3 weeks for effect; avoid grapefruit juice.

SSRI Discontinuation Syndrome

Abrupt stopping leads to flu-like symptoms and the mnemonic "FINISH":

  • Flu-like symptoms
  • Insomnia
  • Nausea
  • Imbalance (dizziness)
  • Sensory disturbances ("brain zaps")
  • Hyperarousal (anxiety/agitation)

Serotonin Syndrome (Emergency)

Occurs with excessive serotonin (e.g., mixing SSRIs with MAOIs, TCAs, St. John's Wort). Mnemonic "HARM":

  • Hyperthermia
  • Autonomic instability (BP fluctuations)
  • Rigidity
  • Mental status changes
    • Action: Stop medication immediately and notify the provider.

VI. Trauma-Informed Care: ACES & PCEs

Mental health is significantly impacted by early life experiences. Nurses use trauma-informed lenses to assess and evaluate care.

  • The Dose-Response Relationship: A direct correlation exists between high ACE scores and chronic adult diseases.
    • ACE Score of 4+: Tripled risk of lung cancer; quadrupled risk of depression.
    • ACE Score of 6+: May lead to premature death within 20 years.
  • Impact on the Brain: ACEs force clients into a permanent "survival mode," making it difficult to suppress fear responses.
  • PCEs (Positive Childhood Experiences): Resilience factors (safe relationships, stable environments) that counteract the toxic stress of ACES.

Trauma-Informed Care (TIC)

Ensure transparency, peer support, and collaboration while avoiding re-traumatization during assessments.

  • What are ACEs and PCEs? Studies indicate that higher ACE scores correlate with increased risks of cancer, cardiovascular diseases, and mental illnesses.

VII. Interprofessional Team & Glossary

The Collaborative Team

  • Occupational Therapist: Helps clients with severe OCD find adaptive ways to perform Activities of Daily Living (ADLs).
  • Psychologist: Conducts Cognitive Behavioral Therapy (CBT) or Exposure & Response Prevention (ERP).
  • Nutritionist: Consults on avoiding stimulants (caffeine, sugar) that trigger anxiety.

Glossary of Therapies

  • Cognitive Reframing: Replacing negative "automatic thoughts" with positive ones.
  • Aversion Therapy: Pairing a maladaptive behavior with a negative stimulus.
  • Flooding: Prolonged exposure to a feared stimulus at full intensity to extinguish fear.

Learning Objectives & Foundations (Reiterated)

By the end of this module, the nursing student will be able to:

  • Recognize Cues: Identify physiological and psychological manifestations across the mental health continuum for anxiety, OCD, and mood disorders.
  • Differentiate Disorders: Distinguish between clinical presentations of depression, bipolar disorder, GAD, and OCD.
  • Prioritize Care: Implement immediate nursing actions based on anxiety levels and suicide risk scores.
  • Apply Pharmacological Safety: Recall key medication classes, side effects, and life-threatening complications like Serotonin Syndrome.
  • Trauma & Cultural Competency: Assess the impact of Adverse Childhood Experiences (ACES) and cultural attitudes on help-seeking behaviors.

The Pathophysiology of Mental Health

Mental health disorders are diagnosed on a spectrum from mild (outpatient) to severe (requiring hospitalization for safety).

  • Neurotransmitter Role: Psychotropic medications primarily regulate Serotonin (5-HT) to manage manifestations of anxiety, mood, and obsessive-compulsive behaviors.
  • Neurobiology: The Cortico-striato-thalamo-cortical circuit is associated with worry and obsessions, while the Amygdala-centered circuit is linked to fear and panic.
  • The Stress Response: The General Adaptation Syndrome (GAS) includes the Alarm Phase (cortisol release), Resistance Stage (body attempts to stabilize), and Exhaustion Phase (energy reserves depleted, leading to chronic disorder).

II. Clinical Presentation: Anxiety Levels & Interventions

Nursing interventions are tailored to the client's current level on the Mental Health Continuum.

Mild Anxiety

  • Manifestations: Sharpened senses, increased focus, and mild restlessness (e.g., finger tapping, nail-biting).
  • Priority Action: Assist the client in identifying triggers and utilizing existing coping mechanisms.

Moderate Anxiety

  • Manifestations: Narrowed perceptual field, selective inattention; physical symptoms such as dry mouth, frequent urination, headache, and insomnia.
  • Priority Action: Use a calm manner and low voice; provide simple, structured instructions and avoid forcing the client to make complex decisions.

Severe Anxiety

  • Manifestations: Sense of "impending doom," tachycardia, and inability to problem-solve. Cognitive ability is significantly impaired.
  • Priority Action: Stay with the client; never leave them alone as their safety is at risk. Focus on physical needs, including fluids, blankets for warmth, and rest.

Panic Level Anxiety

  • Manifestations: Disorganized behavior, detached from reality, hallucinations, and dilated pupils.
  • Priority Action: Safety is the #1 priority. Minimize stimuli and move the client to a quiet environment. If less restrictive interventions fail, medications or seclusion may be required.

III. Mood Disorders: Depression & Bipolar

Depressive Disorders

Depression is both a symptom and a disorder, often triggered by stressors like loss, trauma, or hormonal imbalance.

  • Major Depressive Disorder (MDD): Requires 5 or more DSM-5 criteria over a 2-week period. Key signs include anhedonia (loss of interest) and depressed mood. Other cues include unintentional weight changes, sleep disturbance, psychomotor agitation/retardation, fatigue, and feelings of worthlessness.
  • Dysthymia (Persistent Depressive Disorder): A milder form of chronic depression.
  • Disruptive Mood Dysregulation Disorder: Diagnosed in children who exhibit extreme irritability and trouble functioning in school.
  • Comorbid Conditions: Symptoms of depression are frequently seen in clients with Parkinson's, Huntington's, traumatic brain injury (TBI), or hypothyroidism.

Bipolar Disorder

Clients experience alternating episodes of depression and mania.

  • Bipolar I Disorder: At least one episode of Mania (extreme high levels). Mania symptoms include overactivity, overeating, overspending, insomnia, and rapid speech.
  • Bipolar II Disorder: Characterized by more profound depression and Hypomania (mild mania).
  • Cyclothymic Disorder: Mild cycling between hypomania and mild-to-moderate depression for at least 2 years.
  • Specifications: Nurses should monitor for "Rapid Cycling" (frequent shifts) or "Mixed Features" (mania and depression occurring simultaneously).

IV. Suicide Risk Assessment & Management

Suicide is a behavior, not a disorder. Nurses must immediately assess all clients for risk factors.

The SAD PERSONS Scale

Score one point for each factor to determine the outcome:

  • S: Sex (Male)
  • A: Age (
  • D: Depression
  • P: Previous attempt
  • E: Ethanol (substance use)
  • R: Rational thinking loss
  • S: Social supports lacking
  • O: Organized plan
  • N: No partner
  • S: Sickness (chronic illness).
  • Scoring: 0-2 (Home with follow-up), 3-6 (Consider admission), 7-10 (Admit to hospital).
Immediate Warning Signs

Nurses must be alert to clients stating they feel "hopeless," "trapped," or like a "burden to others".

  • Behavioral Red Flags: Giving away loved possessions, arranging affairs, bidding goodbye to family, or sudden extreme mood swings.
  • Critical Observation: A client who suddenly seems relieved may have finalized a suicide plan and requires immediate line-of-sight observation.
Intervention

Implement Suicide Precautions. Ensure the client is not alone in their room during group activities and prioritize higher-risk clients for constant observation.

Mood Disorders

Major Depressive Disorder (MDD)

Key symptoms (SIGECAPS):

  • S: Sleep disturbance
  • I: Loss of interest (anhedonia)
  • G: Guilt
  • E: Low energy

  • Severe: difficulty focusing, physical symptoms.
  • Panic: loss of control, possible hallucinations.
Interventions:
  • Mild to moderate: teaching is appropriate.
  • Severe to panic:
    • Stay with the patient.
    • Use short, simple statements.
    • Reduce stimuli.

Panic Disorder

Symptoms:
  • Sudden episodes of intense fear.
  • Symptoms: chest pain, shortness of breath, palpitations.
Medications:
  • Benzodiazepines for short-term use.
  • SSRIs for long-term management.

Obsessive-Compulsive Disorder (OCD)

Definitions:
  • Obsessions: intrusive, unwanted thoughts.
  • Compulsions: repetitive behaviors to reduce anxiety.
Nursing care:
  • Do not abruptly stop rituals.
  • Initially allow time for rituals.
  • Gradually limit behaviors.
Medications:
  • SSRIs (first-line), such as fluoxetine.

Suicide Risk

High-risk factors:
  • Previous suicide attempts
  • Older adults
  • Substance use
  • Severe depression
  • Recent loss
Warning signs:
  • Giving away belongings
  • Sudden calmness
  • Saying goodbye
  • Statements about death or worthlessness
Priority interventions:
  • One-to-one observation for high-risk patients.
  • Remove harmful objects.
  • Ask direct questions:
    • "Do you have a plan?"
    • "Do you have access to means?"
    • Asking about suicide does not increase risk.
Priority level:
  • Plan plus means equals highest priority.
Therapeutic communication:
  • Use open-ended statements: "Tell me how you feel."
  • Avoid false reassurance.
  • Avoid minimizing feelings.
Medication Safety:
  • SSRIs: monitor for serotonin syndrome (agitation, fever, tremor).
  • Lithium: avoid dehydration; monitor for toxicity.
  • Benzodiazepines: risk for dependence and respiratory depression.

VIII. ATI Exam Strategy

Key Reminders:

  • Safety is always the priority.
  • Use least restrictive intervention first.
  • Avoid "why" questions.
  • Choose therapeutic communication.
  • When unsure, assess or stay with the patient.

Common ATI Pitfalls:

  • Non-therapeutic responses like "cheer up."
  • Stopping OCD rituals abruptly.
  • Providing detailed teaching during panic.
  • Ignoring suicidal cues.

Practice Questions

NCLEX/ATI-style practice questions focused on mood disorders, anxiety, OCD, and suicide risk.

Question 1: Priority (Depression/Suicide)

A nurse is caring for four clients. Which client should the nurse assess first?
A. A client with depression who reports insomnia
B. A client with depression who started a new antidepressant 2 days ago
C. A client who states, "I don't want to live anymore and I have a gun at home"
D. A client with depression who refuses to eat
Answer: C
Rationale: Plan + means = highest suicide risk. This client requires immediate intervention.

Question 2: Therapeutic Communication

A client says, "I feel like my family would be better off without me." What is the best response?
A. "That's not true. Your family needs you."
B. "Why do you feel that way?"
C. "Tell me more about those feelings."
D. "You shouldn't think like that."
Answer: C
Rationale: Open-ended, therapeutic communication encourages expression. Avoid "why" and false reassurance.

Question 3: Lithium Toxicity

Which finding indicates lithium toxicity?
A. Fine tremor

C. Diarrhea and confusion
D. Increased urination
Answer: C
Rationale: Early effects: tremor, thirst. Toxicity: confusion, diarrhea, ataxia.

Question 4: Anxiety Level

A client is unable to focus, is pacing, and reports feeling overwhelmed. What level of anxiety is this?
A. Mild
B. Moderate
C. Severe
D. Panic
Answer: C
Rationale: Severe anxiety = inability to focus + physical symptoms. Panic involves loss of control.
