Answer to Question 1

ANS: C, D
The problem with very sensitive tests is that the test picks up almost all people with the disease but also many others who do not have the disease. These false positives result in persons needing follow-up diagnostic tests. Additional time, effort, and expense, as well as worry, result until the negative test results are obtained. There is no problem with persons receiving true negative test results and celebrating that knowledge or with persons having their condition correctly diagnosed and treated.

Answer to Question 2

ANS: C, D, E
Vital statistics record births, marriages, divorce, adoptions, and deaths in the community. Useful information would include conditions of birth, such as congenital malformations from the birth records. Death records suggest local mortality and morbidity trends. Overall growth or decline in the community's population can be seen.
