Question

the nurse is talking with the twin brother of a patient with schizophrenia. the brother asks the nurse if schizophrenia is hereditary, related to birth defects, or caused by stress. what information should the nurse provide the patients brother regarding the pathology of the disease?

select all that apply.

the heritability of the disease is estimated to be 70-90%.
the disease is inherited from the mothers side of the family.
relatives of those with schizophrenia have no greater risk of developing the disease.
the development of schizophrenia has been linked to the labor and delivery phase of pregnancy.
there is evidence that both genetic vulnerability and stressful life events can trigger symptoms of schizophrenia.

Explanation:

Analyze genetic factors and heritability

The heritability of schizophrenia is highly significant, with genetic studies estimating it to be approximately 70% to 90%. It is not inherited exclusively from one parent's side, and relatives of individuals with schizophrenia have a substantially higher risk of developing the disorder compared to the general population.

Analyze environmental and developmental factors

Obstetric complications, including issues during the labor and delivery phase of pregnancy (such as hypoxia or birth trauma), are documented environmental risk factors linked to an increased risk of developing schizophrenia later in life.

Analyze stress and vulnerability interaction

The diathesis-stress model is a widely accepted framework explaining that schizophrenia develops from a combination of biological/genetic vulnerability and environmental stressors that trigger the onset of symptoms.

Answer:

• The heritability of the disease is estimated to be 70-90%. (Correct answer)
• The disease is inherited from the mother's side of the family.
• Relatives of those with schizophrenia have no greater risk of developing the disease.
• The development of schizophrenia has been linked to the labor and delivery phase of pregnancy. (Correct answer)
• There is evidence that both genetic vulnerability and stressful life events can trigger symptoms of schizophrenia. (Correct answer)
