Chapter 5 Questions
Question 1 of 5
A nurse cares for a pregnant client who has a family history of sickle cell disease. The client is unsure if she wants to participate in genetic testing. What action should the nurse take?
Correct Answer: A
Rationale: Providing balanced information about the risks and benefits of genetic testing allows the client to make an informed decision without bias. Sharing personal stories or advocating for testing may influence the client's autonomy inappropriately.
Question 2 of 5
A nurse cares for an adult client who has received genetic testing. The clients mother asks to receive the results. How should the nurse respond?
Correct Answer: D
Rationale: Client confidentiality is paramount, and only the client can decide to share genetic test results. The nurse should direct the mother to discuss with the client, respecting the client's autonomy and privacy.
Question 3 of 5
A nurse obtains health histories when admitting clients to a medical-surgical unit. With which client should the nurse discuss predisposition genetic testing?
Correct Answer: A
Rationale: A family history of breast cancer, especially at a relatively young age, indicates a potential risk for hereditary breast cancer, warranting discussion about predisposition genetic testing for genes like BRCA1/2. The pregnant woman's father having sickle cell disease suggests carrier testing, and the man of Eastern European Jewish ancestry may need carrier testing for conditions like Tay-Sachs, not predisposition testing.
