Question 1

The term psychosis refers to disorders that involve ...&#10;A) Multiple personalities.&#10;B) Impairments in reality testing.&#10;C) A lack of empathy for other individuals.&#10;D) Violent behavior.

Accepted Answer

Psychosis is characterized by impairments in reality testing, meaning individuals may have difficulty distinguishing what is real from what is not, often experiencing hallucinations or delusions.

Question 2

Which of the following is an example of a negative symptom?&#10;A) Hallucinations&#10;B) Disorganized speech&#10;C) Delusions&#10;D) Avolition

Accepted Answer

Negative symptoms refer to a reduction or absence of normal behaviors or feelings. Avolition, which is a lack of motivation or ability to initiate and persist in goal-directed activities, is a classic example of a negative symptom. Hallucinations, disorganized speech, and delusions are considered positive symptoms, as they represent an excess or distortion of normal functions.

Question 3

With medical treatment, most individuals with schizophrenia do not experience relapses of psychotic symptoms.

Accepted Answer

While medical treatment can significantly reduce the frequency and severity of psychotic symptoms in individuals with schizophrenia, many still experience relapses, often due to factors like medication non-adherence, stress, or substance use.

Question 4

&#34;Diathesis&#34; in the diathesis-stress model refers to:&#10;A) The schizophrenogenic mother.&#10;B) Inherited factors that determine brain structure and function.&#10;C) Risk factors like early drug use.&#10;D) Events preceding the development of a diagnosable psychotic illness.

Accepted Answer

Diathesis in the diathesis-stress model refers to inherited factors, predispositions, or vulnerabilities that affect brain structure and function, making an individual more susceptible to developing a disorder under stress.

Question 5

Which neurotransmitter is most closely associated with psychotic symptoms and their treatment?&#10;A) Dopamine&#10;B) Serotonin&#10;C) Glutamate&#10;D) Acetylcholine

Accepted Answer

Dopamine is most closely associated with psychotic symptoms and their treatment, as many antipsychotic drugs work by blocking dopamine receptors, particularly in the brain's dopamine pathways.

Question 6

In which of the following ways do individuals with schizotypal personality disorder differ from individuals with schizophrenia?&#10;A) Their unusual ideas and perceptions are not severe or persistent enough to qualify as hallucinations or delusions.&#10;B) They have always manifested the symptoms of their disorder.&#10;C) They tend to be more globally impaired than individuals with schizophrenia.&#10;D) While they have unusual ideas and sensory experiences, they have no problems with social and occupational functioning.

Accepted Answer

Individuals with schizotypal personality disorder differ from those with schizophrenia primarily in the severity and persistence of their symptoms. Their unusual ideas and perceptions are not as severe or persistent enough to qualify as hallucinations or delusions, which are hallmark symptoms of schizophrenia.

Question 7

Schizophrenia is a purely genetic disorder.

Accepted Answer

Schizophrenia is influenced by a combination of genetic, biological, environmental, and psychological factors, not solely by genetics.

Question 8

Which class of drug would you expect to most exacerbate psychotic symptoms if administered to an individual with schizophrenia?&#10;A) An anxiolytic&#10;B) An antidepressant&#10;C) A mood stabilizer&#10;D) A stimulant

Accepted Answer

Stimulants, such as amphetamines or cocaine, can exacerbate psychotic symptoms in individuals with schizophrenia by increasing dopamine activity, which is associated with the exacerbation of psychotic symptoms.

Question 9

Which of the following treatments has been shown to be effective in addressing the positive symptoms of schizophrenia?&#10;A) SSRIs&#10;B) Insulin shock therapy&#10;C) Electroconvulsive therapy&#10;D) Dopamine receptor antagonists

Accepted Answer

Dopamine receptor antagonists are effective in treating the positive symptoms of schizophrenia, such as hallucinations and delusions, by blocking dopamine receptors in the brain.

Question 10

Which of the following is not associated with an increased risk for developing psychosis?&#10;A) Birth during winter months.&#10;B) Having a relative with schizophrenia.&#10;C) Excessive exposure to violent television programs or videogames.&#10;D) Obstetric complications.

Accepted Answer

Excessive exposure to violent television programs or videogames has not been scientifically proven to increase the risk for developing psychosis. Factors like genetics (having a relative with schizophrenia), birth complications, and season of birth (winter months) have been associated with an increased risk.

Question 11

Schizophrenia is usually first diagnosed during which age period?&#10;A) Between 25 and 35 years old&#10;B) Between 20 and 25 years old&#10;C) Between 15 and 30 years old&#10;D) Between 20 and 29 years old

Accepted Answer

The answer of Schizophrenia is usually first diagnosed during which...

Question 12

Lifetime prevalence rates have rates of schizophrenia are between:&#10;A) 0.5% and 1%&#10;B) 5% and 7%&#10;C) 2% and 4%&#10;D) 1% and 2%

Accepted Answer

The answer of Lifetime prevalence rates have rates of schizophrenia...
