Generalized Anxiety Disorder

NCLEX Review Guide: Generalized Anxiety Disorder

Pathophysiology & Assessment

Definition & Characteristics

  • Generalized Anxiety Disorder (GAD) is characterized by excessive, uncontrollable worry about multiple life events or activities for at least 6 months.
  • The anxiety is disproportionate to the actual threat and significantly impairs daily functioning, social relationships, and occupational performance.
  • Physical symptoms include muscle tension, fatigue, restlessness, difficulty concentrating, irritability, and sleep disturbances.

Key Points

  • Duration: Symptoms must persist for at least 6 months
  • Impairment: Must cause significant distress or functional impairment
  • Pervasive: Worry occurs more days than not

Clinical Manifestations

Physical & Psychological Symptoms

  • Physical symptoms include palpitations, sweating, trembling, shortness of breath, nausea, dizziness, and frequent urination.
  • Cognitive symptoms involve racing thoughts, difficulty concentrating, mind going blank, and catastrophic thinking patterns.
  • Behavioral symptoms include restlessness, fidgeting, avoidance behaviors, and seeking excessive reassurance from others.

Clinical Scenario

A 35-year-old client reports constant worry about work performance, family finances, and health issues for 8 months. She experiences muscle tension, fatigue, and difficulty sleeping. She states "I can't turn off my brain."

Nursing Interventions & Management

Therapeutic Approaches

  • Establish therapeutic rapport by providing a calm, non-judgmental environment and validating the client's feelings without reinforcing anxious behaviors.
  • Teach relaxation techniques including deep breathing exercises, progressive muscle relaxation, and mindfulness meditation to manage acute anxiety episodes.
  • Implement cognitive-behavioral strategies by helping clients identify negative thought patterns and develop realistic coping mechanisms.
  1. Assess anxiety level using standardized tools (GAD-7 scale)
  2. Provide psychoeducation about anxiety and its physiological effects
  3. Teach grounding techniques (5-4-3-2-1 sensory method)
  4. Encourage regular exercise and sleep hygiene practices
  5. Monitor medication compliance and side effects

Pharmacological Management

Medication Classes & Nursing Considerations

  • SSRIs (first-line treatment) such as sertraline and escitalopram require 4-6 weeks for therapeutic effect and should be taken consistently.
  • Benzodiazepines provide rapid relief but carry high addiction potential and should only be used short-term for severe symptoms.
  • Buspirone is non-addictive but requires 2-4 weeks for effectiveness and should be taken with food to reduce GI upset.
