C. By identifying the population at risk for the problem
Public health nursing incorporates the nursing process at the community level by first identifying the population at risk for specific health problems or issues. This initial step helps public health nurses target their efforts and resources effectively to address the needs of the community. Once the population at risk is identified, the nursing process can further progress by assessing the community's health needs, planning interventions, implementing programs or interventions, and evaluating the outcomes to improve the overall health and well-being of the population.
