A nurse is preparing a presentation about the relationship of genetics, stress, and developing mental illness. Which of the following information should the nurse plan to include in the presentation?

A. Family studies indicate that mental illness often has a genetic component, so stating there is no genetic association is inaccurate. B. While regular healthcare appointments can help with early identification and management, mental illness cannot be completely prevented solely through routine care; genetics and environmental stressors also play significant roles. C. Twin studies show that both genetics and environmental factors, including stress, contribute to mental illness, so claiming stress is unrelated is incorrect. D. Adoption studies demonstrate that individuals are more likely to develop certain mental illnesses if their biological parents had the disorder, even when raised by adoptive parents. This supports the concept of a genetic correlation in mental illness while also highlighting the interaction with environmental factors.
