A community health nurse is calculating the top three causes of death in a county. Which of the following mortality measures should the nurse use to obtain this data?
Proportionate mortality
Crude mortality rate
Cause-specific mortality rate
Case fatality
The Correct Answer is C
Choice A: Proportionate Mortality
Proportionate mortality refers to the proportion of deaths in a specified population over a period of time attributable to different causes. It is expressed as a percentage of the total number of deaths. While this measure can provide insight into the relative importance of different causes of death, it does not give the actual mortality rate for each cause. Therefore, it is not the best measure for identifying the top three causes of death in a county.
Choice B: Crude Mortality Rate
The crude mortality rate is the total number of deaths from all causes per 1,000 or 100,000 population in a given year. This measure provides an overall picture of the mortality level in a population but does not specify the causes of death. It is useful for general mortality trends but not for identifying specific causes of death.
Choice C: Cause-Specific Mortality Rate
The cause-specific mortality rate is the number of deaths from a specific cause per 100,000 population in a given year. This measure is the most appropriate for identifying the top three causes of death because it provides detailed information on the mortality rate for each specific cause. By calculating the cause-specific mortality rates, the nurse can determine which causes are the most significant contributors to mortality in the county.
Choice D: Case Fatality
Case fatality refers to the proportion of individuals diagnosed with a particular disease who die from that disease within a specified period. It is usually expressed as a percentage. While case fatality provides information on the severity of a disease, it does not give the overall mortality rate for the population or help identify the top causes of death.

Correct Answer is B
Explanation
Choice A Reason:
The number of condoms distributed is an important metric for understanding the reach and utilization of the program. However, it does not directly measure the program's effectiveness in achieving its primary goal, which is to reduce the incidence of sexually transmitted infections (STIs). While distribution numbers can indicate program activity, they do not provide information on health outcomes.
Choice B Reason:
Decrease in the incidence of sexually transmitted infections is the most relevant metric for evaluating the effectiveness of a condom distribution program. The primary objective of such programs is to reduce the transmission of STIs among the target population. By measuring the incidence of STIs before and after the implementation of the program, the nurse can assess whether the program has successfully achieved its goal of improving sexual health outcomes.
Choice C Reason:
The number of students who engage in sex is not a suitable metric for evaluating the effectiveness of a condom distribution program. The program aims to promote safe sex practices rather than influence the number of sexual encounters. Tracking sexual activity does not provide meaningful data on the program's impact on STI prevention.
Choice D Reason:
The location of the community college campus is not relevant to the evaluation of the condom distribution program's effectiveness. While the location might be important for logistical planning and accessibility, it does not provide any information on the program's success in reducing STIs or promoting safe sex practices.
Correct Answer is B
Explanation
Choice A: Incidence is a Measure of Mortality
This statement is incorrect. Incidence refers to the number of new cases of a disease that occur in a specified population during a defined period. It measures the risk of developing the disease, not the number of deaths. Mortality rates, on the other hand, measure the number of deaths due to a disease in a population.
Choice B: Incidence Includes Only People at Risk for the Disease
This statement is correct. The incidence rate is calculated by dividing the number of new cases of a disease by the number of people at risk for the disease in the population during a specified period. This measure helps to understand the likelihood of developing the disease among those who are susceptible.
Choice C: The Denominator for the Incidence Rate Calculation is for the Entire Population
This statement is incorrect. The denominator for the incidence rate calculation should include only those individuals who are at risk of developing the disease, not the entire population. Including the entire population would inaccurately represent the risk, as it would include individuals who cannot develop the disease (e.g., men in the case of breast cancer).
Choice D: New Cases are Not Considered When Calculating an Incidence Rate
This statement is incorrect. The incidence rate specifically measures the number of new cases of a disease that occur in a population during a specified period. Therefore, new cases are a critical component of the incidence rate calculation.
