Answer to Question 1

Ans: A
Feedback:
Incidence density is calculated by dividing the number of new cases occurring during the study period by the person-time units accumulated by subjects during the study period and multiplying the result by the base multiple of 10. In this case, the following equation would result: 42/20,411 = 0.0021 1,000 = 2.1 cases per 1,000 client-days.
