Question 1

Hallucinations and delusions are classified as ____ of schizophrenia

Accepted Answer

Hallucinations and delusions are classified as positive symptoms of schizophrenia. Positive symptoms are characterized by the presence of abnormal experiences, behaviors, or thoughts that are not usually present in healthy individuals. These symptoms include hallucinations, delusions, disorganized speech, and disorganized behavior. Negative symptoms, on the other hand, are characterized by the absence of normal experiences, behaviors, or thoughts that are typically present in healthy individuals. Examples of negative symptoms include flattened affect, lack of motivation or pleasure, and social withdrawal. Temporary or dangerous symptoms are not official classifications of schizophrenia symptoms.

Question 2

Which of the following does not seem to be linked to the development of schizophrenia?

Accepted Answer

The answer of Which of the following does not seem...

Question 3

As a result of cultural values in Western society, many young women

Accepted Answer

Cultural values in Western society place a strong emphasis on thinness as a symbol of beauty and success. This can lead to many young women feeling dissatisfied with their weight and feeling the need to diet in order to achieve this ideal. This pressure can also contribute to the development of eating disorders such as anorexia nervosa or bulimia nervosa in some individuals.

Question 4

Schizophrenic disorders usually emerge

Accepted Answer

Schizophrenic disorders typically emerge during adolescence or early adulthood, with onset usually occurring between the ages of 16 and 30. While it is rare, some individuals may develop symptoms earlier or later.

Question 5

____ involves intense fear of gaining weight, disturbed body image, refusal to maintain normal weight, and dangerous measures to lose weight.

Accepted Answer

The symptoms described match those of anorexia nervosa, which involves a fear of gaining weight and refusal to maintain a healthy weight, often through dangerous measures such as restrictive eating, excessive exercise, and purging. Amenorrhea (A) is the absence of menstrual periods, which can be a symptom of an eating disorder but is not specific to anorexia nervosa. Osteoporosis (B) is a condition characterized by weak bones and is a potential consequence of long-term malnutrition, but is not a defining symptom of anorexia nervosa. Bulimia nervosa (C) is another type of eating disorder, but it involves episodes of binge eating followed by purging, rather than restrictive eating as in anorexia nervosa.

Question 6

Which of the following has been identified as a major factor in the etiology of schizophrenia?

Accepted Answer

Genetic vulnerability has been identified as a major factor in the etiology of schizophrenia. Studies have found that individuals with a first-degree relative who has schizophrenia have a 10% chance of developing the disorder, compared to a 1% chance in the general population.

Question 7

Which of the following statements regarding the etiology of schizophrenia is supported by research?

Accepted Answer

Research has shown that some people inherit a genetically transmitted vulnerability to schizophrenia. However, concordance rates for identical twins are not virtually 100%, indicating that genetic factors are not the sole cause of schizophrenia. Schizophrenia has not been linked to a recessive gene, and the chance of a child developing schizophrenia with two schizophrenic parents is not as high as 90%.

Question 8

Raymond tends to remain completely motionless for long periods of time, during which he seems oblivious to his environment. Raymond would most likely be diagnosed as having which of the following subtypes of schizophrenia?

Accepted Answer

Raymond's behavior of remaining motionless for long periods of time and seeming oblivious to his environment are consistent with the catatonic subtype of schizophrenia, which is characterized by extremes of motor behavior such as immobility or excessive, purposeless movement.

Question 9

Eating disordered behaviors

Accepted Answer

Eating disorders have been documented throughout history in various cultures, but are more prevalent in affluent Western societies where there is a greater emphasis on thinness and beauty standards. While there was an increase in eating disorder diagnoses in the 1980s, the disorders themselves have not disappeared, and while cognitive-behavioral therapy can be helpful, it is not a cure-all for everyone.

Question 10

Anorexia nervosa can eventually lead to which of the following medical problems?

Accepted Answer

Anorexia nervosa can lead to a loss of bone density, gastrointestinal problems, and a loss of menstrual cycles in women. This is because the body is not receiving the necessary nutrients it needs to function properly, leading to a range of medical complications.

Question 11

____ schizophrenia is characterized by a severe deterioration of adaptive behavior.

Accepted Answer

Disorganized schizophrenia is characterized by disorganized speech and behavior, flat or inappropriate affect, and a severe deterioration of adaptive behavior. It can also include delusions or hallucinations, but they are less prominent than in paranoid schizophrenia. Catatonic schizophrenia is characterized by motor disturbances such as immobility or repetitive, purposeless movements. Undifferentiated schizophrenia is a catch-all category for individuals who do not meet the criteria for any specific subtype.

Question 12

About ____ percent of people with schizophrenia enjoy a full recovery.

Accepted Answer

The answer of About ____ percent of people with schizophrenia...

Question 13

____ involves habitually engaging in out-of-control overeating followed by unhealthy compensatory efforts, such as self-induced vomiting and excessive exercise.

Accepted Answer

The description matches the diagnostic criteria for bulimia nervosa, which involves recurrent episodes of binge eating followed by inappropriate compensatory behaviors to avoid weight gain. These behaviors can include self-induced vomiting, excessive exercise, or the misuse of laxatives, diuretics, or other medications. Amenorrhea and osteoporosis are associated with anorexia nervosa, which involves restricting food intake to maintain a low body weight.

Question 14

After the onset of schizophrenia, the course of the disorder is negatively affected by

Accepted Answer

Family dynamics high in expressed emotion, characterized by criticism, hostility, and emotional overinvolvement, have been shown to be a strong predictor of relapse and prolonged periods of hospitalization for schizophrenia patients. On the other hand, families that provide social support and stress-free environments may positively impact the course of schizophrenia, but the negative impact of high expressed emotion is stronger.

Question 15

The prognosis is poorer for schizophrenics who return to families characterized by ____ expressed emotion.

Accepted Answer

Research has shown that families characterized by high expressed emotion (EE) involve criticism, hostility, and emotional overinvolvement, which can cause stress for individuals with schizophrenia and negatively impact their prognosis.

Question 16

Accepted Answer

The answer of Mark has been diagnosed as schizophrenic. It...

Question 17

Research findings indicate that the ____ larger in schizophrenic patients than in normal control subjects.

Accepted Answer

Research has consistently found larger ventricles in schizophrenia patients compared to normal control subjects. The ventricles are fluid-filled spaces in the brain that help protect and cushion it. The enlargement of the ventricles in schizophrenia patients may be due to the loss of brain tissue and decreased brain volume associated with the disorder.

Question 18

Marta sits alone all day, babbling incoherently and giggling to herself. Marta would most likely be diagnosed as having which of the following subtypes of schizophrenia?

Accepted Answer

Marta's symptoms of incoherent speech and inappropriate affect, such as giggling to herself, are characteristic of disorganized schizophrenia.

Question 19

A young woman who says to herself, "I must be thin to be accepted," is demonstrating which of the following factors in the etiology of eating disorders?

Accepted Answer

The young woman's thought process reflects a cognitive factor in the development of eating disorders. Cultural and evolutionary factors may also play a role, but these are not demonstrated in the given scenario. There is limited evidence for a biological component in the etiology of eating disorders, but it is not reflected in this scenario.
