A nurse in an outpatient facility is teaching a client about the development of mental illness.
Which of the following statements by the nurse describes the role of a vulnerability gene?
"It is a gene variant that increases the risk for the development of a specific mental illness.”.
"It is a gene variant that is responsible for the development of a specific mental illness.”.
"It is a gene variant that is responsible for an individual's resilience to stress.”.
"It is a gene variant that determines an individual's likelihood of recovering from mental illness.”.
The Correct Answer is A
Choice A rationale:
A vulnerability gene is a variant that increases the risk for the development of a specific mental illness. It does not guarantee the development of the illness, but it increases susceptibility.
Choice B rationale:
A vulnerability gene is not solely responsible for the development of a specific mental illness. Mental illnesses are typically the result of a combination of genetic, environmental, and psychological factors.
Choice C rationale:
A vulnerability gene does not determine an individual’s resilience to stress. Resilience is a complex trait influenced by multiple genes and environmental factors.
Choice D rationale:
A vulnerability gene does not determine an individual’s likelihood of recovering from mental illness. Recovery is influenced by a variety of factors, including treatment, support systems, and individual resilience.

Choice A rationale:
Stress from a new job could indeed be a cause of a depressed mood. Changes in life circumstances, such as starting a new job, can be stressful and lead to feelings of depression.
Choice B rationale:
High blood pressure is not typically a direct cause of a depressed mood. It is a physical health condition that needs to be managed, but it does not directly cause depression.
Choice C rationale:
An elevated heart rate is not typically a direct cause of a depressed mood. It is a physical symptom that can be associated with many different conditions, but it does not directly cause depression.
Choice D rationale:
Renal dysfunction is not typically a direct cause of a depressed mood. It is a physical health condition that needs to be managed, but it does not directly cause depression.
Correct Answer is C
Explanation
Choice A rationale:
Physical harm is not a necessary condition for developing a trauma-related disorder. Emotional and psychological trauma can also lead to these disorders.
Choice B rationale:
Genetics can predispose individuals to trauma-related disorders, but it is not the sole cause. Environmental factors, such as experiencing or witnessing a traumatic event, play a significant role.
Choice C rationale:
Experiencing or witnessing a traumatic event can indeed result in developing a trauma-related disorder. This is because the event can cause significant emotional distress and impact the individual’s ability to cope.
Choice D rationale:
While chemical imbalances in the brain can be associated with trauma-related disorders, they are typically a result of the disorder rather than the cause.
