Which of the following is an example of secondary data a nurse should review when identifying health needs in the community?

Secondary data refers to information that has already been collected and analyzed for purposes other than the specific research question at hand. In this context, reviewing previous health survey results serves as a prime example of secondary data. These results provide insights into community health indicators, trends, and needs that have been established through prior assessments. By evaluating this existing data, a nurse can identify patterns or issues that affect the health of the population without needing to collect new data from the community.

On the other hand, methods such as a windshield survey, community forum, and direct interviews involve collecting new information directly from the environment or individuals within the community, categorizing them as primary data. In community health nursing, secondary data is crucial because it allows for an efficient review of established trends and can inform the development of targeted interventions without the time and resource investment required for new data collection. Thus, reviewing previous health survey results is instrumental in shaping health initiatives and understanding the community's needs effectively.
