Final answer:
Public health nurses should use both community-level and broader statistics to inform community-specific interventions and contribute to the formulation of effective public health policies and resource allocation.
Step-by-step explanation:
When comparing the morbidity/mortality rates of a community to national and state statistics, one of the key implications for public health nurses is that they should prioritize community-specific interventions. While community data is paramount, it is also crucial to consider broader statistics which can help to identify trends, allocate resources, and formulate policies.
Public health nurses must analyze various levels of data to effectively protect and improve community health, taking into account the local context while also utilizing wider public health strategies and resources.
