A nurse is reviewing the medical record of a client who recently has been diagnosed with schizophrenia. Which of the following finding is a genetic risk factor associated with the development of schizophrenia?

Biologic parent with schizophrenia

Biologic grandparent with Fragile X syndrome

Biologic uncle with Rett syndrome

Biologic sibling with Down syndrome.

Answer and Explanation

The Correct Answer is A

A. Biologic parent with schizophrenia: Having a biological parent with schizophrenia significantly increases an individual's risk of developing the disorder due to genetic and hereditary factors. Family studies have shown that the risk of schizophrenia is higher among first-degree relatives, indicating a strong genetic component.
B. Biologic grandparent with fragile X syndrome: Fragile X syndrome is a genetic disorder associated with intellectual disability but is not directly related to the risk of developing schizophrenia. While genetic factors can play a role in various mental health disorders, fragile X syndrome does not specifically indicate an increased risk for schizophrenia.
C. Biologic uncle with Rett syndrome: Rett syndrome is a neurological disorder that primarily affects females and is not associated with an increased risk of schizophrenia. The genetic risk for schizophrenia is more relevant among immediate family members rather than extended relatives like uncles.
D. Biologic sibling with Down syndrome: Down syndrome is a chromosomal disorder caused by an extra copy of chromosome 21 and does not directly increase the risk of developing schizophrenia. While individuals with Down syndrome may experience other mental health issues, the genetic risk for schizophrenia is not associated with this condition.

Correct Answer is C

Explanation

A. A history of schizophrenia: Schizophrenia is a distinct mental health disorder characterized by psychosis, including delusions and hallucinations. While it may co-occur with dissociative disorders, it is not considered a direct risk factor for dissociative identity disorder (DID).
B. Borderline personality disorder: While there is some overlap in symptoms between borderline personality disorder and dissociative identity disorder, borderline personality disorder itself is not a risk factor for developing DID. However, individuals with DID may also present with features of borderline personality disorder.
C. History of trauma during the developmental years: This is a significant risk factor for the development of dissociative identity disorder. DID is often associated with severe trauma, particularly during childhood, such as physical, emotional, or sexual abuse. The disorder can serve as a coping mechanism to dissociate from the traumatic experiences.
D. A history of self-injurious behavior: Self-injurious behavior may be a symptom associated with various mental health disorders, including borderline personality disorder, but it is not specifically identified as a risk factor for dissociative identity disorder.

A. Initial use of substances began in adulthood. B. The developing brain is exposed to substances at an early age. C. The brain already has cognitive deficits that causes it to be vulnerable to addiction. D. Medical insurance availability for substance use disorder treatment.

Correct Answer is B

Explanation

A. Initial use of substances began in adulthood: Starting substance use in adulthood is generally associated with a lower risk of developing addiction compared to early initiation. Early exposure to substances can significantly affect brain development and increase vulnerability to addiction.
B. The developing brain is exposed to substances at an early age: Early exposure to substances during critical periods of brain development can disrupt normal neurological processes and increase the likelihood of developing substance use disorders later in life. This is a well-established risk factor for addiction.
C. The brain already has cognitive deficits that cause it to be vulnerable to addiction: While cognitive deficits can increase vulnerability to addiction, this factor is more specific and not as broadly applicable as the impact of early substance exposure on a developing brain.
D. Medical insurance availability for substance use disorder treatment: While having access to treatment is important for recovery, it does not increase the potential for addiction. In fact, access to treatment can help mitigate the effects of addiction and support recovery efforts.
