The community health nurse is administering flu shots to children at a local playground. What is the rationale for this nurse's action?

A) To prevent individual illness
B) To prevent community outbreak of illness
C) To prevent outbreak of illness in the family
D) To prevent needs of the local population groups

The nurse is trying to prevent a community outbreak of illness. By focusing on subpopulations (children), the community health nurse cares for the community as a whole and considers the individual or the family as only one member of a group at risk. Community-based nursing, as opposed to community health nursing, focuses on the needs of the individual or family. Public health nursing focuses on meeting the population groups' needs.
