Key Takeaways

  • Anxiety exists on a continuum from mild (enhanced learning and problem-solving) to panic (complete loss of control and inability to function)
  • During a panic attack, stay with the client, maintain a calm demeanor, and use short, simple sentences
  • Generalized Anxiety Disorder (GAD) involves excessive worry occurring more days than not for at least 6 months
  • Phobias involve intense, irrational fear of specific objects or situations that leads to avoidance behaviors
  • Obsessive-Compulsive Disorder (OCD) involves intrusive thoughts (obsessions) and repetitive behaviors (compulsions) performed to reduce anxiety

Anxiety Disorders and Mental Health Concepts

Anxiety is a universal human experience, but when it becomes excessive or interferes with daily functioning, it crosses into the realm of mental health disorders. The NCLEX tests your understanding of anxiety levels, common anxiety disorders, and appropriate nursing interventions.


The Four Levels of Anxiety

Anxiety exists on a continuum from mild to panic. Each level has distinct characteristics and requires different nursing approaches.

LevelCharacteristicsLearning AbilityNursing Focus
MildAlert, slight tension, enhanced perceptionOptimalUse for teaching
ModerateNarrowed perception, selective attentionDecreasedRedirect, structure
SevereGreatly reduced perception, difficulty thinkingSignificantly impairedSafety, simple tasks
PanicComplete loss of control, terrorImpossibleStay present, safety

Mild Anxiety

Mild anxiety is adaptive and actually enhances performance.

Characteristics:

  • Alert and attentive
  • Perceptual field is broad
  • Motivation increased
  • Slight restlessness
  • Heightened awareness

Nursing considerations:

  • Optimal time for teaching
  • Learning is enhanced
  • Problem-solving improved
  • No intervention needed unless it escalates

Moderate Anxiety

Moderate anxiety begins to narrow the perceptual field.

Characteristics:

  • Selective inattention (focuses on immediate concern)
  • Voice changes (may tremble or increase in pitch)
  • Physical symptoms (increased heart rate, sweating)
  • Sees, hears, and grasps less
  • Can be redirected with assistance

Nursing interventions:

  • Use therapeutic communication
  • Help client focus on the present
  • Break tasks into smaller steps
  • Provide structure
  • Encourage relaxation techniques

Severe Anxiety

Severe anxiety significantly impairs functioning.

Characteristics:

  • Greatly reduced perceptual field
  • Difficulty thinking clearly
  • Focus on small or scattered details
  • Physical symptoms intensify
  • Communication may become scattered
  • Unable to problem-solve

Nursing interventions:

  • Reduce stimuli in the environment
  • Stay with the client
  • Use simple, direct statements
  • Do NOT teach at this level
  • Focus on safety
  • Provide one task at a time

Panic-Level Anxiety

Panic represents a complete loss of control and is a psychiatric emergency.

Characteristics:

  • Terror, dread, feeling of impending doom
  • Inability to communicate coherently
  • Physical symptoms at maximum (palpitations, chest pain, dyspnea)
  • May experience depersonalization/derealization
  • Unable to function
  • May be immobilized or hyperactive

Nursing interventions for panic:

  1. Stay with the client - Never leave someone in panic alone
  2. Maintain calm demeanor - Your calmness is contagious
  3. Use short, simple sentences - "You are safe. I am here with you."
  4. Move to a quiet area - Reduce environmental stimuli
  5. Encourage slow breathing - "Breathe with me. In... Out..."
  6. Do not touch without permission - Touch may increase panic
  7. Safety is priority - Prevent injury during crisis

Post-panic: Once the panic subsides, explore triggers and develop coping strategies.


Common Anxiety Disorders

Generalized Anxiety Disorder (GAD)

Definition: Excessive, uncontrollable worry about multiple aspects of life occurring more days than not for at least 6 months.

Symptoms:

  • Restlessness or feeling "on edge"
  • Easy fatigability
  • Difficulty concentrating
  • Irritability
  • Muscle tension
  • Sleep disturbance

Nursing considerations:

  • Teach relaxation techniques
  • Encourage regular exercise
  • Limit caffeine intake
  • Medications: SSRIs, SNRIs, Buspirone

Panic Disorder

Definition: Recurrent, unexpected panic attacks with persistent concern about future attacks.

Characteristics of a panic attack:

  • Sudden onset of intense fear
  • Peaks within minutes
  • Physical symptoms: palpitations, sweating, trembling, shortness of breath, chest pain
  • Fear of dying or "going crazy"
  • Duration: typically 10-30 minutes

Nursing priority: During an attack, stay present and help the client feel safe.


Phobias

Definition: Intense, irrational fear of specific objects, situations, or activities that leads to avoidance.

TypeFear OfExamples
Specific phobiaObjects/situationsSpiders, heights, blood
Social phobiaSocial situationsPublic speaking, eating in public
AgoraphobiaPlaces of escape difficultyCrowds, open spaces, public transit

Treatment:

  • Systematic desensitization (gradual exposure)
  • Cognitive-behavioral therapy
  • Medications may be adjunctive

Obsessive-Compulsive Disorder (OCD)

Obsessions: Intrusive, unwanted thoughts, images, or urges that cause marked anxiety.

Compulsions: Repetitive behaviors or mental acts performed to reduce anxiety caused by obsessions.

Common themes:

ObsessionRelated Compulsion
Contamination fearsExcessive handwashing
Doubt ("Did I lock the door?")Repeated checking
Need for symmetryArranging, counting
Forbidden thoughtsMental rituals, praying

Nursing considerations:

  • Do NOT interrupt rituals abruptly (increases anxiety)
  • Set limits gradually
  • Allow extra time for daily activities
  • Treatment: ERP (Exposure and Response Prevention), SSRIs

Post-Traumatic Stress Disorder (PTSD)

Definition: Develops after exposure to a traumatic event involving actual or threatened death, serious injury, or sexual violence.

Symptom clusters:

  1. Intrusion - Flashbacks, nightmares, intrusive memories
  2. Avoidance - Avoiding reminders of the trauma
  3. Negative changes in mood/cognition - Blame, detachment, negative beliefs
  4. Hyperarousal - Hypervigilance, startle response, sleep problems

Nursing considerations:

  • Create a safe, trusting environment
  • Avoid retraumatization
  • Trauma-informed care approach
  • Treatment: Trauma-focused CBT, EMDR, medications

Defense Mechanisms

Clients use defense mechanisms unconsciously to protect themselves from anxiety. Common mechanisms tested on NCLEX:

MechanismDefinitionExample
DenialRefusing to accept realityCancer patient says "There must be a mistake"
ProjectionAttributing own feelings to others"You're the one who's angry, not me!"
DisplacementRedirecting emotions to safer targetYelling at spouse after conflict with boss
RationalizationMaking excuses to justify behavior"I failed because the test was unfair"
RegressionReturning to earlier developmental stageAdult sucking thumb during stress
RepressionUnconsciously blocking painful memoriesCannot remember childhood abuse
SublimationChanneling impulses into acceptable activitiesAnger channeled into sports (healthy)

Medications for Anxiety

Drug ClassExamplesKey Points
SSRIsSertraline, Paroxetine, EscitalopramFirst-line for most anxiety disorders; 2-4 weeks for effect
SNRIsVenlafaxine, DuloxetineAlso first-line; monitor blood pressure
BenzodiazepinesLorazepam, Alprazolam, DiazepamShort-term only; dependence risk; avoid abrupt discontinuation
BuspironeBusparNon-sedating; no dependence; takes 2-4 weeks
Beta-blockersPropranololPerformance anxiety; blocks physical symptoms

Benzodiazepine safety: Monitor for sedation, respiratory depression, falls. Flumazenil reverses overdose.

  • Mild anxiety = best time to teach

  • Don't interrupt OCD rituals abruptly
  • Phobias = systematic desensitization
