medium · NCLEX-RN health-promotion
A 24-year-old client is considering predictive testing for HD. During the intake, the client asks, 'If I have the gene, does it mean I will definitely get the disease, or just that I am at higher risk?' Which response by the nurse is accurate?
- The test only indicates a predisposition, and environmental factors can prevent the disease from appearing, for this client.
- If the mutation is present, the disease is 100% penetrant, meaning symptoms will develop if you live a normal lifespan.
- It depends on whether you inherited the gene from your mother or your father.
- The test results are only 95% accurate, so there is always a chance you will remain healthy, as the next nursing response.
