NU 664C Psychotic Disorders & Schizophrenia Exam (2025/2026) – 100+ Graded Questions on DSM-5 Diagnosis, Positive/Negative Symptoms, Delusions, Antipsychotics, Neurobiology & Imaging

This NU 664C Psychotic Disorders and Schizophrenia Exam Review (2025/2026) provides over 100 exam-ready, A+ rated questions and answers aligned with advanced practice mental health nursing standards. Designed for PMHNP students and psychiatric nurse clinicians, the document offers a full-spectrum review of psychotic spectrum disorders, emphasizing diagnostic criteria, neurobiology, symptom differentiation, pharmacologic interventions, and functional outcomes. The content starts with foundational distinctions among positive symptoms (hallucinations, delusions, disorganized speech), negative symptoms (alogia, avolition, anhedonia), and cognitive symptoms (impaired attention, memory, executive function)—crucial for DSM-5-based assessments. Also included are key subtypes of psychotic disorders such as: Schizophrenia Schizoaffective Disorder (bipolar & depressive types) Schizophreniform Disorder Brief Psychotic Disorder Delusional Disorder Capgras Syndrome A breakdown of hallucination types (auditory, visual), thought disorders (thought echo, insertion, delusional perception), and delusion categories (grandiose, somatic, persecutory, religious) is provided with real-case features. Pharmacologic management includes first- and second-generation antipsychotics: Second-gen (SGA): Aripiprazole, clozapine – mechanisms, receptor targets, and treatment-resistant protocols First-gen (FGA): Haloperidol, chlorpromazine – dopaminergic activity, IM/PO routes, and dose equivalence Monitoring for neuroleptic malignant syndrome (NMS) and understanding IM depot formulations (short/long-acting) are also covered. The neurobiological section discusses: PET and CT imaging findings – enlarged ventricles, reduced gray matter Neurotransmitter abnormalities – dopamine dysregulation, elevated glutamate Affected brain regions – hippocampus, thalamus, prefrontal cortex, basal ganglia, occipital and temporal lobes Evoked potentials and electrophysiologic abnormalities (e.g., P300) Neurodevelopmental disruptions and reduced brain symmetry The document also highlights: Course specifiers (first episode, continuous, remission phases) DSM-5 duration criteria Prognostic indicators Catatonic features (mutism, echolalia, echopraxia, stupor) Recommended for: PMHNP students and psychiatric-mental health nursing learners Graduate coursework in psychopharmacology, neuropsychiatry, and diagnostics Board and licensing exam prep (ANCC PMHNP) Clinicians reviewing acute psychosis management protocols This review combines theoretical knowledge with practical application, making it a critical study tool for mastering the complexity of psychotic disorders in advanced practice.
