Question 6

Joelle has taken her son to many doctors claiming that he has Morgellons disease.She says that she often pulls fiber-like threads from his skin and that the boy has rashes and skin lesions that never heal.Which statement about this disease is accurate?

Accepted Answer

The CDC began conducting research on Morgellons disease in early 2008 to investigate the condition, although it remains controversial and not officially recognized as a distinct medical disorder.

Question 7

Which factor is associated with the best chances for recovering from schizophrenia?

Accepted Answer

Having a high educational background has been associated with better outcomes for individuals with schizophrenia. Education can increase one's ability to understand and adhere to treatment, navigate complex medical systems, and potentially access better job opportunities and social support. While being male was once thought to be associated with a better prognosis, current research suggests that gender is not a significant factor in long-term recovery. Being single or having a low premorbid level of functioning have been associated with poorer outcomes.

Question 8

Researchers are exploring the role of quantifiable, heritable, trait-related characteristics that are thought to underlie illnesses that exist before, during, and following remission of a disorder.These characteristics are called ____.

Accepted Answer

The term describing the quantifiable, heritable, trait-related characteristics that underlie disorders is “endophenotypes”. Genotypes refer to an individual's complete set of genes, phenotypes refer to the observable traits or characteristics of an individual resulting from interactions between their genetics and environment, and genetic markers are specific DNA sequences that are known to vary between individuals and can be used to identify differences in genetic makeup.

Question 9

Which ordering of the phases of schizophrenia is accurate?

Accepted Answer

The phases of schizophrenia are generally considered to be premorbid, prodromal, active, and residual. Premorbid refers to the period before the onset of symptoms, prodromal is the early period where symptoms start to appear but are not yet fully formed, active is the period of full-blown symptoms and psychosis, and residual is the period after active symptoms have subsided but some residual symptoms may still be present. Choice C correctly orders these phases in the correct sequence.

The other choices may provide some additional information but are not as decisive in distinguishing between the three disorders.

Question 13

A follow-up study by Wiersma and colleagues (1998)reported complete remission of symptoms for approximately what percentage of individuals diagnosed with schizophrenia?

Accepted Answer

The follow-up study by Wiersma and colleagues (1998) reported complete remission of symptoms for approximately 25% of individuals diagnosed with schizophrenia.

Question 18

Lydia Tan has been living with her paranoid schizophrenic husband on an isolated farm for so long that she has come to accept his irrational beliefs.When she visits her sister, her delusions weaken.Mrs.Tan's condition is called ____.

Question 19

Which statement about research on the genetics of schizophrenia is accurate?

Accepted Answer

Although there is still much debate and controversy, evidence suggests that genetic factors play a significant and complex role in the development of schizophrenia. Studies on families, twins, and genetic sequencing have all pointed towards the involvement of genetic variations and mutations in increasing the risk for schizophrenia. However, it is important to note that environmental factors can also influence the manifestation of the disorder.
