ATI Psychiatric Exam 1 | Nurselytic

Correct Answer: A

Rationale: The correct answer is A: It is a gene variant that increases the risk for development of a specific mental illness. Vulnerability genes are genetic variations that predispose individuals to a higher likelihood of developing a particular mental illness when exposed to certain environmental factors. This statement accurately describes the role of vulnerability genes in increasing the risk for mental illness development.



Choices B, C, and D are incorrect.
Choice B states that vulnerability genes are responsible for an individual's resilience to stress, which is inaccurate as vulnerability genes actually increase susceptibility to mental illness rather than resilience.
Choice C suggests that vulnerability genes are solely responsible for the development of a mental illness, which is an oversimplification as mental illness development is influenced by a combination of genetic, environmental, and other factors.
Choice D implies that vulnerability genes determine an individual's likelihood of recovery from mental illness, which is not true as vulnerability genes primarily affect the risk of developing mental illness rather than recovery outcomes.
