20. Which statement would be most appropriate for the nurse to make when assisting a family in compiling a family health history?
a. When you have completed this history, it will not need to be updated.
b. Looking back at two generations of biological relatives will be sufficient.
c. The purpose of completing a family history is to decrease genetic susceptibility.
d. A family history is a useful tool when considering your future health risks.
A family history is a useful tool to help families know about their health risks and prevent disease in themselves and their close relatives. It is recommended that families develop a three generation history and update it on a regular basis. Completion of a family history will not decrease genetic susceptibility; rather it will make families more aware of what that susceptibility may be.

21. The Genetic Information Nondiscrimination Act (GINA):
a. Protects individuals from discrimination based on their genetic information
b. Allows health insurance companies to deny coverage for pre-existing conditions
c. States employers may collect genetic information from employees as needed
d. Requires employees to report genetic disorders to their employer
GINA was designed to prohibit the improper use of genetic information in health insurance and employment. It protects individuals from discrimination based on their genetic information, prevents denial of coverage based solely on genetic predisposition to disease, and limits disclosure of genetic information.
