NURS 420 EXAM 8 | QUESTIONS AND
ANSWERS | 2026 UPDATE | WITH
COMPLETE SOLUTIONS.
Catatonia - ANSWER>characterized by marked psychomotor disturbance, either excessive motor activity or virtual
immobility and motionless. Motor immobility may included catalepsy or stupor. Excessive motor activity is
apparently purposeless and not influenced by external stimuli. Other behaviors include extreme negativism,
mutism, peculiar movements, echolalia, or echopraxia.
Delusional Disorder - ANSWER>the client has one or more non-bizarre delusions (focus of delusion is believable).
The delusion may be persecutory, erotomanic, grandiose, jealous, or somatic in content, psychosocial functioning is
not markedly impaired, and behavior is not obviously odd or bizarre
Brief psychotic disorder - ANSWER>the client experiences the sudden onset of at least one psychotic symptoms,
such as delusions, hallucinations, or disorganized speech or behavior, which lasts from 1 day to 1 month. The
episode may or may not have an identifiable stressor or may follow childbirth
, Shared psychotic disorder - ANSWER>Two people share a similar delusion. The person with this diagnosis develops
this delusion in the context of a close relationship with someone who has psychotic delusions, most commonly
siblings, parent and child, or husband, and wife. The more submissive or suggestible person may rapidly improve if
separated from the dominant person.
Schizotypal personality disorder - ANSWER>This involves odd, eccentric behaviors, including transient psychotic
symptoms. Approximately 20% of persons with this personality disorder will eventually be diagnosed with
schizophrenia.
Schizophrenia Etiology - Biologic theories - ANSWER>-Genetic factors: genetic risk is polygenic, twins 50% identical,
15% paternal, 15% with one parent, 35% if both parents
-Neuroanatomic and neurochemical factors (less brain tissue and cerebrospinal fluid; dopamine excess and
serotonin modulation of dopamine, enlarged ventricles in the brain and cortical atrophy)
-Immunovirologic factors (viral exposure, cytokines (chemical messengers between immune cells); researchers
focusing on infections in pregnant women as a possible origin, after influenza epidemics, respiratory ailments)
Cultural Considerations for schizophrenia - ANSWER>-Ideas considered delusional in one culture possibly
commonly accepted by other cultures
- Auditory or visual hallucinations as normal part of religious experiences in some cultures
