Final answer:
Community health nurses use objective indicators such as morbidity rates, prevalence of diseases, and access to healthcare to determine the needs of an aggregate group. Personal preferences of the nurse do not qualify as valid indicators. These metrics assist in developing suitable health interventions for the population.
Step-by-step explanation:
The student asked which indicator(s) accurately identify the needs of an aggregate group in the context of community health nursing. To assess the needs of an aggregate group, a community health nurse must rely on a variety of indicators, which may include morbidity and mortality rates, prevalence of specific diseases, access to healthcare services, socioeconomic factors, and environmental data. These indicators provide objective and evidence-based metrics to understand the health status and needs of a population.
It is important to note that the nurse's preference is not a valid indicator for assessing community needs. The assessment should be based on empirical data and standard public health metrics. By evaluating these indicators, nurses can develop and implement appropriate health programs and interventions aimed at improving the overall health outcomes of the aggregate group.
