Stress and Anxiety

Key Points

• Stress is the body-mind response to perceived challenge; anxiety is fear or unease that can become impairing when persistent.
• Acute stress may be adaptive, but chronic stress worsens physical and psychiatric outcomes.
• Anxiety exists on a continuum from mild arousal to panic-level dysregulation.
• Nursing management combines coping-skills coaching, lifestyle supports, and targeted therapies.

Pathophysiology

Stress activates sympathetic and neuroendocrine pathways (fight-or-flight), increasing heart rate, blood pressure, vigilance, and stress-hormone output. Repeated or prolonged activation can disrupt sleep, immune function, metabolism, mood regulation, and cognition.

Anxiety disorders emerge when fear-processing systems remain overactive and disproportionate to actual threat.

Classification

• Stress response domains: Physiologic, emotional, and behavioral reactions.
• Coping domains: Problem-focused, emotion-focused, and resilience-oriented strategies.
• Anxiety-intensity levels: Mild, moderate, severe, and panic.

Nursing Assessment

NCLEX Focus

Differentiate adaptive stress from pathologic anxiety by duration, intensity, and functional impact.

• Assess stressors, symptom pattern, and duration.
• Assess physiologic manifestations (sleep change, autonomic signs, appetite/energy shifts).
• Assess cognitive distortions (catastrophizing, overgeneralization, threat overestimation).
• Assess current coping style effectiveness and available social supports.
• Assess safety concerns, including escalation to panic, self-harm risk, or substance misuse.

Nursing Interventions

• Teach grounding, paced breathing, and relaxation techniques for acute symptom reduction.
• Coach problem-solving and time-management skills for controllable stressors.
• Promote sleep hygiene, activity, and nutrition to reduce physiologic burden.
• Reinforce resilience-building habits and support-network engagement.
• Coordinate psychotherapy/pharmacotherapy referral when anxiety impairs function.

Chronic-Stress Normalization

Treating severe chronic stress as “normal life pressure” delays care and increases morbidity.

Pharmacology

Medication options for anxiety may include SSRIs/SNRIs, buspirone, and short-term benzodiazepine use in selected contexts. Nursing care must monitor dependency risk, withdrawal risk, side effects, and functional response.

Clinical Judgment Application

Clinical Scenario

A client reports persistent worry, insomnia, muscle tension, gastrointestinal upset, and declining concentration at work for months.

Recognize Cues: Multi-domain anxiety burden with functional decline. Analyze Cues: Pattern exceeds short-term adaptive stress response. Prioritize Hypotheses: Priority is anxiety disorder evaluation and immediate coping support. Generate Solutions: Combine symptom-regulation skills with therapy/medication pathway. Take Action: Implement grounding education, sleep plan, and referral coordination. Evaluate Outcomes: Reassess anxiety severity, function, and coping capacity.
