Final answer:
A rural community health nurse should gather information from migrant farmworker advocacy groups to identify health services data for migrant farmworkers.
Step-by-step explanation:
To identify health services data for migrant farmworkers, a rural community health nurse should gather information from migrant farmworker advocacy groups. These groups are specifically focused on the needs and health concerns of the migrant farmworker population and can provide valuable data on accessing healthcare services. Additionally, they may have information on community resources and programs available to improve health care delivery for this minority group.
Local grocery stores and social media platforms are unlikely to provide relevant health services data for migrant farmworkers. National weather reports are unrelated to health care delivery for this specific population.
