The public health nurse is assigned to the population of clients in an inner-city community. The nurse identifies which of the following as a priority intervention?

The correct answer is C: Perform a windshield survey. This is the priority intervention because it involves assessing the community's overall health needs and resources by physically observing the environment. It helps in identifying key health issues, resources, and potential areas for intervention. Developing a survey on teen pregnancies (A) may be important but not a priority without assessing the community first. Holding a focus group on immunizations (B) is valuable but may not address the broader health needs of the community. Interviewing the elderly at the senior's center (D) is specific and may not represent the entire community.
