Anxiety-Related Disorders

Key Points

  • Anxiety disorders involve persistent, excessive fear/worry that disrupts daily functioning.
  • Major subtypes include generalized anxiety disorder, phobias, and panic disorder.
  • Effective care combines psychoeducation, psychotherapy, and selective pharmacologic support.
  • Nursing priorities include risk assessment, panic de-escalation, and coping-skill reinforcement.
  • Anxiety disorders frequently co-occur with depressive disorders and substance-use disorders, which changes risk and treatment planning.
  • Panic attacks can be expected (cue-triggered) or unexpected (no clear trigger), and this distinction helps with diagnosis and exposure planning.

Pathophysiology

Anxiety disorders reflect dysregulated threat detection, autonomic arousal, and maladaptive cognitive processing. Genetic predisposition, stress/trauma exposure, and learned avoidance patterns all contribute to symptom persistence.

Avoidance temporarily lowers distress but reinforces long-term anxiety severity.

Classification

  • GAD: Excessive, hard-to-control worry across multiple domains on most days for at least 6 months, with at least 3 associated symptoms (for example restlessness, fatigue, concentration difficulty, irritability, muscle tension, sleep disturbance) and functional impairment.
  • Social anxiety disorder: Marked fear/anxiety in social situations with possible scrutiny/negative evaluation, persistent (typically 6 months or more), with avoidance or endurance under intense distress and functional impairment.
  • Agoraphobia: Intense fear of at least 2 situation domains (for example public transportation, open spaces, enclosed spaces, crowds/lines, or being outside home alone) due to perceived difficulty escaping/help-seeking during panic-like or embarrassing symptoms.
  • Phobia disorders: Excessive, out-of-proportion fear tied to specific objects/situations (for example flying, heights, animals, injections, blood) with immediate anxiety response, active avoidance or endurance with intense fear, persistence (typically 6 months or more), and functional impairment.
  • Panic attack episode: Abrupt surge of intense fear peaking within minutes with at least 4 core panic symptoms.
  • Panic-attack pattern: Expected attacks follow identifiable cues (for example flying/public speaking); unexpected attacks occur without clear warning and may occur during rest or sleep.
  • Panic disorder: Recurrent unexpected panic attacks plus at least 1 month of persistent attack-related worry and/or maladaptive behavior change (for example avoidance).
  • Separation anxiety disorder: Persistent fear of separation from attachment figures with avoidance of separation/being alone, separation nightmares or somatic symptoms, and duration thresholds of at least 4 weeks in children and typically at least 6 months in adults.
  • Selective mutism: Anxiety-linked failure to speak in specific social situations despite intact language ability, usually with early-childhood onset and social-evaluation fear pattern.

Nursing Assessment

NCLEX Focus

Distinguish panic attack from medical emergencies while treating both as urgent until ruled out.

  • Assess symptom duration, triggers, and functional impairment.
  • Use anxiety-focused mental status examination findings (distress signs, speech/motor changes, mood/affect, thought content, insight/judgment) to classify current severity.
  • Escalate urgent medical evaluation for panic-like red flags such as chest pain, shortness of breath, or palpitations while maintaining anxiety de-escalation support.
  • Assess panic physiology (palpitations, dyspnea, chest discomfort, derealization).
  • Distinguish a DSM-style panic-attack episode from broader panic-level anxiety dysregulation on the anxiety continuum when documenting assessment findings.
  • In suspected panic disorder, assess whether at least one prior attack was followed by at least 1 month of persistent concern about additional attacks/consequences or panic-linked maladaptive avoidance behavior.
  • During acute panic episodes, perform rapid vital-sign assessment and escalate immediately for chest pain, severe dyspnea, or collapse-risk symptoms while anxiety care proceeds.
  • Assess avoidance behaviors and safety impact on work/school/social life.
  • For specific phobias, assess immediate trigger reactivity and threat-overestimation patterns, plus somatic fear cues (for example palpitations, sweating, tremor, dyspnea, dizziness, GI distress).
  • For agoraphobia, assess feared-situation count/domain, escape-help beliefs, avoidance severity, and housebound risk; note that agoraphobia may occur with or without panic disorder.
  • For social anxiety, assess feared-scrutiny contexts (conversation, eating/drinking while observed, performance tasks) and fear of negative evaluation.
  • Assess comorbid depression, substance use, and sleep disturbance.
  • Assess baseline risk factors for anxiety disorders (for example childhood behavioral inhibition/shyness traits, trauma exposure, and family history of anxiety/mental disorders).
  • Assess treatment readiness and prior response to therapy/medication.
  • Use focused psychosocial interviewing (for example PQRSTU structure) to clarify anxiety provocation, body-region symptoms, severity trend, timing, and client understanding.
  • Screen directly for suicide risk and non-suicidal self-injury (NSSI); normalize screening language and escalate immediately when risk cues are present.
  • Include cultural and spiritual assessment (for example CFI and FICA frameworks) and evaluate family-dynamics stress/support effects on anxiety patterns.
  • Screen with brief tools such as GAD-2 when indicated; a score of 3 or higher supports need for further evaluation.
  • When available, use structured severity tools (for example adult generalized-anxiety severity measures) to trend response over time.
  • Consider age-specific screening context: broad adult screening is commonly recommended through age 64 (including pregnancy/postpartum), while evidence in adults older than 65 is less definitive and requires individualized judgment.
  • Evaluate for medical or substance-related causes that can mimic anxiety (for example thyroid/cardiopulmonary disease, electrolyte abnormalities, hypoglycemia/hypoxia, caffeine, medications, or illicit drugs) before final diagnostic conclusions.
  • In new-onset anxiety with concentration complaints, assess high-caffeine intake and nonprescribed herbal supplements before attributing symptoms to a primary anxiety disorder alone.
  • In children and adolescents, assess whether anxiety is developmentally expected versus function-impairing, and screen for contextual threats such as bullying or adverse childhood experiences (ACEs).
  • In children with social anxiety, assess developmental expression patterns (for example crying, tantrums, freezing, clinging, shrinking, or failing to speak in social situations).
  • When selective mutism is suspected, assess freezing/rigidity, avoidance-security behaviors (for example eye-contact avoidance, hiding, gesture-only communication), and anxiety-linked somatic activation in speaking situations.

Nursing Interventions

  • Use calm, brief communication and breathing coaching during panic episodes.
  • Guide gradual exposure and coping rehearsal for phobic avoidance reduction.
  • Teach anxiety-management skills (grounding, relaxation, cognitive reframing).
  • Support adherence to psychotherapy (CBT, DBT, and exposure-based approaches including systematic desensitization paired with relaxation/imagery).
  • For phobia treatment planning, include exposure format selection (in vivo, imaginal, or virtual-reality exposure) based on trigger type, access, and client tolerability.
  • For mild-to-moderate anxiety, use calm active listening, open-ended exploration, low-stimulation space, and simple physical activity to reduce escalation.
  • Monitor medication use and reinforce safe short-term versus long-term strategies.
  • During extreme anxiety or panic, do not leave the client alone; use a low-stimulus environment, stay present for safety, and provide short, concrete directions.
  • During severe anxiety/panic, use one-step communication in a slow low-pitched tone and prioritize physiologic stabilization (fluids, warmth, rest, and nutrition support).
  • Reinforce health teaching on symptom triggers, including caffeine, OTC cold medications, illicit substances, and herbal products that may worsen anxiety or interact with prescribed therapy.
  • Use collaborative medication/substance history review to identify “self-treatment” patterns (for example energy drinks or supplements for sleep/focus) that can perpetuate anxiety symptoms.
  • Provide psychoeducation that helps clients identify and name anxiety symptoms, and encourage support-group or trusted-support engagement when available.
  • Implement anxiety care across APNA-style domains (coordination of care, health teaching, pharmacologic-biologic-integrative therapies, milieu therapy, and therapeutic relationship/counseling).
  • For recurrent panic presentations, document trigger context, physiologic findings, interventions, and response trajectory to improve continuity and trigger-pattern prevention.

Avoidance Reinforcement Loop

Repeated avoidance strengthens fear conditioning and worsens long-term disability.

Pharmacology

Common options include SSRIs/SNRIs and buspirone for long-term management, with cautious short-term benzodiazepine use when indicated. Hydroxyzine and situational beta-blocker use may help selected clients with short-term symptom control. Gabapentin is sometimes used off-label in selected anxiety contexts but has mixed evidence and sedation/cognitive side-effect burden. Nurses should monitor sedation, dependence risk, medication-response timelines, and interaction triggers; in older adults, benzodiazepines are generally avoided when possible because oversedation, confusion, and fall risk are amplified.

Clinical Judgment Application

Clinical Scenario

A client with recurrent sudden dyspnea, chest tightness, and fear of dying avoids public transport after two episodes.

  • Recognize Cues: Panic-pattern symptoms with escalating avoidance behavior.
  • Analyze Cues: Functional impairment now extends beyond isolated episodes.
  • Prioritize Hypotheses: Priority is panic disorder stabilization and avoidance-cycle interruption.
  • Generate Solutions: Initiate panic education, exposure-based plan, and medication review.
  • Take Action: Implement coping protocol and coordinate psychotherapy referral.
  • Evaluate Outcomes: Track attack frequency, avoidance reduction, and daily-function recovery.
