Which level is NOT part of the Intervention Wheel's levels of practice?

• A. Public Policy
• B. Community
• C. Systems
• D. Individual/Family

Answer: (A)

The Intervention Wheel organizes practice across three levels of influence: individual or family, community, and systems. These levels describe where you target your nursing interventions to impact health outcomes.

Public Policy isn’t a level of practice. It’s a type of intervention you might use at the systems level to influence rules, laws, or organizational procedures. So, while policy development or policy advocacy are actions you can take within the systems level, the levels themselves are the individual/family, community, and systems.

To see how this fits: working with an individual or family focuses on personal health behaviors and needs; working with a community involves mobilizing groups and addressing community-wide factors; and working at the systems level aims to change the broader environment, including policies and organizational practices that affect population health. Public Policy sits under the systems level rather than being a standalone level.
