Question 1

Because there is considerable overlap among the types of schizophrenia and because patterns of behavior shift over time,many patients are simply classified as suffering from __________ schizophrenia.

Accepted Answer

The term "undifferentiated schizophrenia" is used to classify patients who do not fit neatly into one of the other subtypes of schizophrenia. This may be because their symptoms are not consistent with a single subtype or because they show a mixture of symptoms from different subtypes.

Question 2

Schizophrenia in which there are prominent psychotic symptoms,but none of the specific features of catatonic,disorganized or paranoid types would be classified as a(n)__________ schizophrenia.

Accepted Answer

Undifferentiated schizophrenia is a subtype in which the individual displays prominent psychotic symptoms such as delusions, hallucinations or disordered thinking, but does not fit into the specific criteria for catatonic, disorganized or paranoid types. This subtype may also be referred to as atypical schizophrenia.

Question 3

Mothers who contracted either rubella or influenza during the middle of their pregnancies,or who experienced malnutrition during pregnancy or complications at the time of birth have children with a higher risk of developing

Accepted Answer

Studies have shown that rubella or influenza during the middle of pregnancy, malnutrition during pregnancy or birth complications can increase the risk of developing schizophrenia in the child.

Question 4

Paranoid schizophrenia is characterized by auditory hallucinations and

Accepted Answer

Paranoid schizophrenia is specifically characterized by delusions of grandeur and persecution, as well as auditory hallucinations. Other symptoms may include disorganized speech, disorganized behavior, and negative symptoms like lack of emotion or motivation. Severe depression, silliness and bizarre behavior, and mutism are not necessarily characteristic of paranoid schizophrenia.

Question 5

The LEAST prone to violence would be a person who

Accepted Answer

The option B states that the person is a former mental patient who is not actively psychotic. Studies have shown that mental illness on its own is not a good predictor of violence. In fact, people with mental illness are more likely to be victims of violent crimes than perpetrators. Therefore, an individual who is not actively psychotic and has received treatment for their mental illness is the least prone to violence.

Question 6

Women who are exposed during the middle of pregnancy to which of the following have children who are more likely to become schizophrenic?

Accepted Answer

Women who are exposed to a flu virus or rubella during the middle of pregnancy have been found to have children who are more likely to become schizophrenic. This is due to the fact that these viruses can cause inflammation and damage to the developing brain, which may increase the risk of developing schizophrenia later in life.

Question 7

Ginny's mother was exposed to the influenza virus midway through her pregnancy as well as being malnourished during much of her pregnancy.Due to these prenatal factors,Ginny is more likely to

Accepted Answer

Exposure to influenza and malnutrition during pregnancy can lead to disturbances in brain development, increasing the risk of psychotic disorders like schizophrenia in later life.

Question 8

Emily has barricaded herself in her home.She believes that aliens are trying to take over her mind and body.She has wrapped herself in aluminum foil in order to prevent the penetration of the cosmic rays that she has "seen" coming down through her ceiling.Emily believes that she alone has been given the power by God to tell real humans from aliens pretending to be humans so she can destroy them.Emily would most likely be diagnosed as having

Accepted Answer

Emily's beliefs are consistent with paranoid schizophrenia, which is characterized by delusions (belief in things that are not true) and hallucinations (seeing or hearing things that are not there). Emily's delusions involve aliens taking over her mind and body, and her belief that she has been given special powers by God to destroy them.

Question 9

James Huberty,who killed 21 people at a fast-food restaurant in San Ysidro,California,felt persecuted and cheated by life.Shortly before he went to the fast-food restaurant,he announced to his wife that he was "going hunting humans." Huberty had been hearing hallucinated voices for some time.Huberty would most likely be diagnosed with which disorder?

Accepted Answer

Huberty's feelings of persecution, the presence of hallucinations and his announcement of going "hunting humans" suggest symptoms commonly seen in paranoid schizophrenia.

Question 10

Regarding schizophrenia,which of the following statements is FALSE?

Accepted Answer

Disorganized schizophrenia is not the most common subtype of schizophrenia. In fact, it is the least common subtype. The most common subtype is paranoid schizophrenia.

Question 11

Children who were exposed to psychological trauma or deviant communication patterns have a higher risk of developing

Accepted Answer

Exposure to psychological trauma or deviant communication patterns is associated with a higher risk of developing schizophrenia, as these factors can contribute to the onset of the disorder in vulnerable individuals.

Question 12

Regarding the mentally ill and violence,which of the following statements is/are TRUE?

Accepted Answer

Studies have shown that people with mental illness are no more violent than the general population, and that substance abuse is a bigger factor in violence. Additionally, research has found that people who are actively experiencing psychosis are not necessarily violent, and that former mental patients are not more likely to be violent. Therefore, option A is false. Option B is also incorrect because while severe mental illness can be associated with violence, people who are actively psychotic may be too disorganized or overwhelmed to be violent. Option C is the most accurate because evidence suggests that poverty, youth, and alcohol/drug use are stronger predictors of violence than mental illness alone.

Question 13

Which of the following prenatal situations has NOT been shown to increase the risk of the developing child being more vulnerable to having schizophrenia later in life?

Accepted Answer

Having an extra chromosome at pair 16 is not related to an increased risk of schizophrenia. However, the other choices have been shown to increase the vulnerability of the developing child to have schizophrenia later in life. Maternal inflammation caused by contracting infections like influenza and rubella during pregnancy has been associated with an increased risk of schizophrenia. Malnutrition during pregnancy has been linked to the disruption of normal fetal brain development, which can also increase the risk of later schizophrenia.

Question 14

Which major subtype of schizophrenia has become rare in Europe and North America?

Accepted Answer

Catatonic schizophrenia has become rare in Europe and North America, likely due to changes in diagnostic criteria and the increased use of antipsychotic medications.

Question 15

Frequent auditory hallucinations and bizarre,unconvincing delusions of persecution and grandeur are typical of

Accepted Answer

Frequent auditory hallucinations and bizarre, unconvincing delusions of persecution and grandeur are typical of paranoid schizophrenia. Paranoid psychosis and disorganized paranoia are not specific diagnoses, and paranoid delusional disorder typically involves more believable, non-bizarre delusions. Therefore, B is the best choice.

Question 16

Regarding violence and psychoses,which of the following statements is FALSE?

Accepted Answer

While it is true that mental illness in general is not a strong predictor of violence, people who are actively psychotic and currently experiencing psychotic symptoms have an increased risk for violence. This is because they may have delusions or hallucinations that cause them to feel threatened or paranoid, leading them to act aggressively in self-defense or to protect themselves. It is important to note that this risk does not apply to all people with mental illness or even all people with psychosis, but rather to those who are actively symptomatic.

Question 17

Sara believes that she is the daughter of Jesus Christ.Every room in her apartment is adorned with crosses; and she wears three around her neck at all times to prevent evil spirits from entering her body.Sara also hears "voices," which tell her to "get down on her knees," which she readily obeys even if she is in the middle of the street.The "voices" have also commanded her to throw rocks at two of the neighborhood boys because they are the sons of Satan.Sara would most likely be diagnosed as having

Accepted Answer

Sara's belief that she is the daughter of Jesus Christ, her hearing of "voices," and her acting on their commands to harm others all point towards a diagnosis of paranoid schizophrenia.

Question 18

During childhood,individuals who develop schizophrenia seem to have

Accepted Answer

Research suggests that childhood trauma, such as physical or sexual abuse, is a risk factor for the development of schizophrenia. While intellectual stimulation or the use of defense mechanisms may play a role in mental health, they are not specifically linked to the development of schizophrenia in childhood. Precocious abilities may be a potential marker for schizophrenia, but it is not a definitive factor.

Question 19

Under what circumstances do mental problems represent an elevated risk of violence?

Accepted Answer

Delusions and hallucinations, particularly those involving paranoia, can lead to violent behavior due to the individual’s distorted beliefs and perception of reality. Mood disorders and somatoform disorders do not necessarily increase the risk of violence. The fourth option is incorrect as there are certain mental disorders that can increase the risk of violence.

Question 20

The most common type of schizophrenia is the __________ subtype.

Accepted Answer

The paranoid subtype of schizophrenia is the most common type, accounting for approximately 40% of all cases. Individuals with paranoid schizophrenia typically experience delusions and auditory hallucinations, often centered around a theme of persecution or grandiosity.
