Composite health department written as a model document. Essential services are quoted from the 2020 revision.
A Short History That Explains the Framework
In 1893 Lillian Wald opened a nursing settlement on Henry Street on Manhattan's Lower East Side, where the term public health nurse took hold. In 1988 the Institute of Medicine's report The Future of Public Health grouped public health's work under three core functions, which it called assessment, policy development and assurance, (Institute of Medicine, 1988). In 2020 the 10 Essential Public Health Services were revised, with equity placed at the center of the wheel (Public Health National Center for Innovations, 2020).
Mapping Rules
Each activity is assigned its primary core function and one essential service, quoted exactly from the 2020 list. Where an activity serves two functions, the second is noted.
Mapping Table
1. Community health assessment. Assessment. Service 1: "Assess and monitor population health status, factors that influence health, and community needs and assets." Nursing: data collection, key informant interviews.
2. Tuberculosis contact tracing. Assessment. Service 2: "Investigate, diagnose, and address health problems and hazards affecting the population." Nursing: case investigation, directly observed therapy.
3. Communicable disease reporting. Assessment. Service 2. Nursing: follow-up of reportable conditions.
4. Restaurant inspections. Assurance. Service 6: "Utilize legal and regulatory actions designed to improve and protect the public's health." Nursing: none.
5. Immunization clinic. Assurance. Service 7: "Assure an effective system that enables equitable access to the individual services and care needed to be healthy." Nursing: administration, outreach.
6. Maternal-child home visiting. Assurance. Service 7. Nursing: home visits.
7. Health education campaigns. Policy development, second function assurance. Service 3: "Communicate effectively to inform and educate people about health, factors that influence it, and how to improve it." Nursing: teaching.
8. Coalition on childhood lead. Policy development. Service 4: "Strengthen, support, and mobilize communities and partnerships to improve health." Nursing: member.
9. Housing code advisory work. Policy development. Service 5: "Create, champion, and implement policies, plans, and laws that impact health." Nursing: none.
10. Workforce training. Assurance. Service 8. Nursing: preceptors for students.
11. Program evaluation. Assurance. Service 9. Nursing: quality data.
12. Accreditation and infrastructure. Assurance. Service 10. Nursing: none.
Reading the Nursing Column
Public health nurses appear in nine of the twelve rows, most heavily under assessment and assurance. The empty cell that matters most is service 5: no nurse sits where housing policy is made, although lead in old housing is one of the neighborhood's clearest hazards. The scope and standards for the specialty include advocacy and policy work among a public health nurse's responsibilities (American Nurses Association, 2022).
One Change
Add a public health nurse seat to the city's housing code advisory board, so that what nurses see on home visits reaches the people writing the rules.

How this NU450 Unit 2 example is structured
The table carries the argument, and everything around it prepares or interprets it. History comes first but stays short and functional: each date explains a piece of the framework used later, so the section never becomes a timeline for its own sake. The mapping rules are stated before the table, including how activities serving two functions are handled, by listing the primary one and noting the second. Each essential service is quoted exactly from the 2020 list, since paraphrase tends to drift back toward the 1994 version. The nursing column is the analysis's own contribution: public health nurses appear in nine of the twelve rows, most heavily under assessment and assurance. The gap section reads the empty cells and finds no activity under service 5 with nursing involvement. One recommendation ends the paper: a nurse seat on the housing code advisory board.

NU450 Unit 2 questions, answered
Where do nurses fit among the three core functions?
Across all three, though unevenly in most departments. Nurses assess through surveillance, screening and home visits, assure through case management and clinic services, and contribute to policy development less often than their knowledge would justify. The sample's nursing column makes that pattern visible. Where a prompt focuses on one nursing role, map that role's activities rather than the whole department's.
Can I analyze my own local health department?
Yes, and many prompts invite it. Health departments usually publish their community health assessment, improvement plan and annual reports, which list activities you can map. Accredited departments also report against standards built on the essential services. Use only public documents, and describe what the department itself publishes rather than guessing at internal work.
How much history belongs in a core functions paper?
Enough to explain the framework and no more. Wald and the Henry Street Settlement anchor public health nursing, the 1988 report introduced the core functions, and the 2020 revision updated the services. Half a page usually covers it. If your prompt asks for history as its own section, expand it, but keep linking each event to the framework.
