1. The most commonly supported neuroanatomic theory of schizophrenia suggests which
etiology?
A) Excessive amounts of dopamine and serotonin in the brain
B) Ineffective ability of the brain to use dopamine and serotonin
C) Insufficient amounts of dopamine in the brain
D) Decreased brain tissue in the frontal and temporal regions of the brain
Ans: D
Feedback:
Decreased brain tissue in the frontal and temporal regions of the brain is the most
commonly supported neuroanatomic theory that suggests the etiology of schizophrenia.
The other theories are neurochemical.
2. The nurse reviews current literature and identifies that which of the following are
included in current studies of biologic theories regarding the etiology of schizophrenia?
Select all that apply.
A) That there is a particular pathologic structure associated with the disease.
B) That genetics is the cause of schizophrenia.
C) Persons with schizophrenia have decreased brain volume and abnormal brain
function in the frontal and temporal areas of persons with schizophrenia.
D) The brain activity of persons with schizophrenia differs from people who do not
have schizophrenia.
E) That the etiology of schizophrenia may be related to the body’s response to
exposure of a virus.
Ans: B, C, D, E
Feedback:
In the first half of the 20th century, studies focused on trying to find a particular
pathologic structure associated with the disease, largely through autopsy. Such a site
was not discovered. The biologic theories of schizophrenia focus on genetic factors,
neuroanatomic and neurochemical factors (structure and function of the brain), and
immunovirology (the body’s response to exposure to a virus).
3. The student nurse correctly recognizes that which one of the following findings is best
supported by genetic studies in the etiology of schizophrenia?
A) If a person has schizophrenia, distant relatives are also at risk.
B) That there is no relationship at all between schizophrenia and genetics.
C) That there is a weak correlation between genetics and schizophrenia.
D) That schizophrenia is at least partially inherited.
Ans: D
Feedback:
The most important studies have centered on twins; these findings have demonstrated
that if one identical twin has schizophrenia, the other twin has a 50% chance of
developing it as well. Fraternal twins have only a 15% risk. This finding indicates that
schizophrenia is at least partially inherited.

4. The nurse is assessing for negative symptoms of schizophrenia in a newly admitted
client. The nurse would note which behavior as indicative of a negative symptom?
A) Difficulty staying on subject when responding to assessment questions
B) Belief of owning a transportation device allowing for travel to the center of the
Earth
C) Hesitant to answer the nurse’s questions during the assessment interview
D) Mimicking the postural changes made by the nurse during the assessment
interview
Ans: C
Feedback:
A negative symptom of schizophrenia is alogia, or the tendency to speak very little or to
convey little substance of meaning (poverty of content). Associative looseness
(fragmented or poorly related thoughts and ideas), delusions (fixed false beliefs that
have no basis in reality), and echopraxia (imitation of the movements and gestures of
another person whom the client is observing) are all positive symptoms.
5. The client with schizophrenia believes the student nurses are there to spy on the clients.
The client is suffering from which of the following symptoms?
A) Hallucinations
B) Delusions
C) Anhedonia
D) Ideas of reference
Ans: B
Feedback:
Delusions are fixed false beliefs that have no basis in reality. Hallucinations are false
sensory perceptions or perceptual experiences that do not exist in reality. Ideas of
reference are false impressions that external events have special meaning for the person.
Anhedonia is feeling no joy or pleasure from life or any activities or relationships.
