The three levels of practice described by the Intervention Wheel are:

• A. Individual, Family, Community
• B. Population, Policy, Practice
• C. Primary, Secondary, Tertiary
• D. Micro, Meso, Macro

Answer: (A)

The Intervention Wheel organizes public health nursing practice around three levels of the unit being served: individuals, families, and communities. This means you tailor interventions to the size of the target group and the way health issues play out at each level.

Working with individuals focuses on one person and aims to influence personal health behaviors, risk factors, and health status through methods like health teaching, counseling, screening, and referrals. When the target is a family, the focus expands to the family unit, taking into account dynamics, routines, and support systems to improve health outcomes for all members—often using family-centered education and coordination of resources. At the community level, the emphasis is on the broader environment, organizations, and systems, employing actions such as coalition building, community organizing, policy development, advocacy, and environmental changes to improve population health.

These three levels are distinct from other frameworks like primary/secondary/tertiary prevention (stages of disease), or micro/meso/macro (levels of social systems), or population/policy/practice as a general categorization.
