Answer to Question 1

Ans: A
Feedback:
Rate is the primary measurement used to describe the occurrence (quantity) of a state of health in a specific group of people in a given time period. Ratio is a fraction that represents the relationship between two numbers. Relative risk ratio is the ratio of the incidence rate in the exposed group to the incidence rate in the nonexposed group. Sensitivity is the ability of a test to correctly identify people who have a health problem or the probability of testing positive if the health problem is truly present.

Answer to Question 2

Ans: A, B, D
Feedback:
The primary way to demonstrate prevention or control of a health problem is to compare epidemiologic statistics before and after the implementation of the health service. Planning and evaluation are continuous processes. As new data become available, modification in health services may be necessary, and those modifications require evaluation. Evaluation of the program and planning of future interventions should not be based on the clients' perception of its effectiveness, which is likely to not be accurate. Because factors may vary significantly from community to community, it would be more appropriate to compare before and after statistics in your own community rather than statistics with other communities.
