Final answer:
Community nursing activities start on the first contact with the patient, allowing nurses to assess needs and plan care, including health education and coordination with community resources.
Step-by-step explanation:
Nursing activities related to community nursing typically begin at the time of the first contact with the patient. Community nursing focuses on the prevention, education, and the management of health conditions in community settings, rather than just in hospital or acute care environments. By starting at the first contact, community nurses can fully assess the patient's needs, environment, and resources to create a comprehensive care plan that includes health promotion, disease prevention, and coordinating care among different services and community resources.
