Schizophrenia

Key Points

• Schizophrenia is a severe psychotic disorder with positive, negative, and cognitive symptom domains.
• Course often includes prodromal, acute, and recovery/residual phases with relapse risk.
• Effective treatment combines antipsychotic medication, psychosocial interventions, and family support.
• Nursing priorities include safety, therapeutic alliance, adherence support, and functional recovery planning.

Pathophysiology

Schizophrenia likely emerges from multifactorial neurodevelopmental and neurochemical mechanisms involving genetic vulnerability plus environmental stressors. Major theories include dysregulated dopamine, glutamate/NMDA hypofunction, and serotonin-pathway effects.

Clinical burden is high, with functional impairment, medical comorbidity risk, and shortened life expectancy when untreated or undertreated.

Classification

• Symptom domains: Positive (delusions/hallucinations/disorganization), negative (blunted affect, avolition, anhedonia), cognitive deficits.
• Phase model: Prodromal, acute psychosis, and recovery/residual phase.
• Treatment layers: Pharmacologic management plus psychosocial and community-based supports.

Nursing Assessment

NCLEX Focus

In acute psychosis, prioritize safety and command-hallucination risk assessment first.

• Assess psychosis content, especially command hallucinations and harm risk.
• Assess symptom domain profile and current illness phase.
• Assess medication history, side effects, and adherence barriers.
• Assess social determinants affecting relapse risk (housing, support, access, stigma).
• Assess insight/anosognosia and capacity for collaborative planning.

Nursing Interventions

• Maintain calm, low-stimulation, nonthreatening therapeutic milieu.
• Use de-escalation and least-restrictive safety protocols when agitation escalates.
• Support antipsychotic adherence and monitor EPS/metabolic/adverse effects.
• Deliver psychoeducation to client/family on relapse warning signs and response plans.
• Coordinate psychosocial supports (CBT, social-skills, case management, community reintegration).

Confrontation Harm

Directly challenging fixed delusions in acute phase can increase paranoia and disrupt alliance.

Pharmacology

Antipsychotics are core treatment (first- and second-generation classes). Nursing care includes class-specific adverse-effect surveillance (EPS, metabolic effects, sedation, NMS risk), adherence coaching, and timely prescriber communication for optimization.

Clinical Judgment Application

Clinical Scenario

A young adult with recent withdrawal, paranoia, command hallucinations, and disorganized speech attempts to elope from the unit.

Recognize Cues: Acute psychosis with immediate safety threat. Analyze Cues: Command content and behavioral disorganization elevate harm risk. Prioritize Hypotheses: Priority is immediate safety stabilization and symptom control. Generate Solutions: Initiate de-escalation, acute medication plan, and structured environmental controls. Take Action: Implement safety protocol and begin therapeutic engagement with simple communication. Evaluate Outcomes: Reassess risk reduction, symptom trajectory, and readiness for phase-transition goals.
