NR 547 Midterm Exam 2026/2027 | 50+ Questions & Answers | Psychiatric Diagnosis, Anxiety, OCD, Psychosis & DSM-5 | Chamberlain University

The NR 547 Midterm Exam 2026/2027 is a 13-page psychiatric and mental health review containing 50+ questions, answers, diagnostic criteria, screening tools, laboratory values, and treatment concepts. The document concentrates on psychiatric differential diagnosis, medical and substance-related rule-outs, anxiety disorders, panic disorder, agoraphobia, social anxiety disorder, adjustment disorder, obsessive-compulsive disorder, psychotic disorders, schizophrenia-spectrum conditions, and psychiatric assessment scales. Its question-and-answer format is designed for focused midterm preparation and rapid review of diagnostic distinctions and treatment principles. The opening section focuses on the psychiatric differential-diagnosis process. The material presents six considerations: ruling out malingering or factitious disorder, excluding a substance-related etiology, excluding a medical etiology, identifying the specific primary psychiatric disorder, distinguishing adjustment disorder from “other specified” and “unspecified” conditions, and establishing whether symptoms fall within the boundary of no mental disorder. It also distinguishes the use of “other specified” from “unspecified” diagnoses and emphasizes the importance of gathering sufficient clinical information before assigning a definitive diagnosis. The document then reviews laboratory evaluation for psychiatric presentations, connecting physical conditions with symptoms that may resemble or contribute to psychiatric disorders. Students review CBC and iron studies when investigating anemia in patients with fatigue and decreased motivation, BUN and creatinine, thyroid-function testing for symptoms such as impaired concentration, insomnia, mood changes, and reduced mental alertness, as well as vitamin B12 and vitamin D levels. The resource specifically associates low vitamin B12 with potential depression, mania, psychotic manifestations, and cognitive impairment. A major portion addresses generalized anxiety disorder (GAD), panic disorder, agoraphobia, and social anxiety disorder. GAD content includes persistent excessive worry, sleep disturbance, restlessness, fatigue, muscle tension, concentration difficulties, amygdala and prefrontal-cortex activity, and the duration criterion presented in the document. Treatment concepts include SSRIs, buspirone, and adverse effects associated with SSRIs. The material also reviews the Hamilton Anxiety Rating Scale (HAM-A) and GAD-7, including symptom-severity ranges provided in the study guide. For panic disorder and phobic disorders, students review recurrent unprovoked panic attacks, anticipatory anxiety, palpitations, choking or smothering sensations, nausea, dizziness, paresthesias, trembling, and derealization. The document identifies SSRI therapy combined with CBT as first-line treatment for panic disorder. Agoraphobia is differentiated by fear involving situations such as being outside the home alone, crowds or lines, public transportation, open spaces, and enclosed spaces. Social anxiety disorder content addresses fear of scrutiny or judgment, avoidance of social interactions, performance anxiety, CBT, propranolol, and benzodiazepines in the treatment scenarios described by the source. The OCD section provides detailed examination of obsessions, compulsions, insight, diagnostic features, assessment, and treatment. Obsessions covered include contamination, pathological doubt, somatic concerns, aggressive or sexual thoughts, and a need for symmetry or ordering. Compulsions include checking, washing, counting, confessing, arranging, repeated comparisons, and time-consuming ritualistic behavior. Treatment content emphasizes SSRIs and exposure-response therapy, while the Yale-Brown Obsessive Compulsive Scale is presented for grading symptom severity. The document also discusses PANDAS and its proposed association between beta-hemolytic streptococcal infection, autoimmune processes, basal-ganglia inflammation, and childhood OCD symptoms. The final section concentrates on psychosis and schizophrenia-spectrum disorders. Conditions reviewed include schizophrenia, schizoaffective disorder, schizophreniform disorder, brief psychotic disorder, delusional disorder, and catatonia. Students compare disorders according to symptom patterns and duration, including schizophrenia with continuous disturbance lasting at least six months, schizophreniform presentations lasting more than one month but less than six months, and brief psychotic episodes lasting more than one day but less than one month according to the document. Catatonia is reviewed through findings such as mutism, withdrawal, staring, posturing, rigidity, negativism, echolalia, echopraxia, and grimacing, with benzodiazepines identified as its primary treatment in the material. The resource concludes with important psychosis assessment instruments. The Brief Psychiatric Rating Scale (BPRS) is described as a clinician-rated tool covering symptoms such as hostility, suspiciousness, hallucinations, and grandiosity and as useful for evaluating changes during treatment. The Positive and Negative Syndrome Scale (PANSS) is identified as a measure used to evaluate schizophrenia-related clinical symptoms and distinguish positive from negative symptom domains, particularly in research settings.
