Core Functions Role Brief: A Public Health Nurse and the 1,350 Children Under Three in One Rural County
The Population
The population is all children aged 0 through 35 months living in a composite rural Midwestern county of about 38,000 people, roughly 1,350 children, with about 450 births a year. The county has one critical access hospital without a delivery unit, two family medicine clinics, no pediatrician, and a county health department with three public health nurses, of whom I am the one assigned to maternal and child health. The nearest pediatric practice and birthing hospital are 45 minutes away. This brief sets out what changes when the patient is this group rather than any one child, and where my work falls among the core functions of public health.
What Changes When the Patient Is a Group
In clinical practice, a nurse assesses one child, plans that child's care, and evaluates that child's response. In public health nursing, the same steps apply to the whole population: the assessment asks how many children in the county are up to date on vaccines, not whether one child is; the plan is aimed at the reasons many children fall behind; and the evaluation asks whether the county's rate changed. The professional definition of public health nursing centers on this population focus, drawing on nursing along with the social and public health sciences (American Public Health Association, Public Health Nursing Section, 2013). Individual care still happens, in immunization clinics and home visits, but it is chosen and organized because of what it does for the population.
The Three Core Functions, Applied to This Population
Public health work is commonly organized into three core functions, assessment, policy development, and assurance, first set out in a national report on the state of public health (Institute of Medicine, 1988), and elaborated since as ten essential public health services (Public Health National Center for Innovations, 2020). For the county's youngest children, each function becomes specific work.
| Core function | What it means for children under three here | My share of the work |
|---|---|---|
| Assessment | Measuring vaccination coverage, well-child visit completion, and birth outcomes; identifying which families fall behind and why | Pulling coverage data from the state immunization registry quarterly; reviewing birth records; interviewing families and clinic staff |
| Policy development | Using data to shape local decisions, such as clinic hours, child care immunization requirements, and standing orders for vaccination | Presenting coverage data to the board of health; drafting a standing order proposal with the medical director; working with child care centers on record reviews |
| Assurance | Making sure services exist and reach families: vaccines available, clinics accessible, gaps filled | Running the health department's monthly immunization clinic; enrolling the two family medicine clinics in the federal children's vaccine program; home visits to families who miss appointments |
Where I Sit Among the Other Services
The health department's other nurses cover communicable disease investigation and adult services; the environmental health specialist covers water, septic, and food safety; the WIC program, operated by the department, sees about 60% of the county's infants for nutrition services. The WIC office is where I will find most families with young children, so a large share of my assessment and assurance work happens alongside WIC visits. The family medicine clinics provide most well-child care; my role is not to replace them but to track the population they serve and fill gaps they cannot.
What the Role Is Not
The role is not primary care for the county's children, and it is not limited to running clinics. A nurse who spent all available hours vaccinating children in the health department clinic would serve the children who came, but would not know about the ones who did not, and would never address why they did not. The core functions require time for assessment and policy work even when the clinic schedule is full.
First Priorities
Three priorities follow for my first year: establish a quarterly coverage report for children 19 to 35 months from the state registry, which does not currently exist for the county; learn from families, WIC staff, and clinic staff why children fall behind; and ensure that both family medicine clinics can vaccinate every eligible child at every visit. National data show that coverage among young children is lower in rural areas than in cities, so the county's rate is likely to be below state and national levels (Hill et al., 2023), but that is an expectation to test, not a finding. If the county turns out to be near the state rate, the priorities will shift toward the other measures, well-child visits and birth outcomes, rather than holding to a plan the data do not support.

NU 655 Unit 1 instructions, in plain terms
Unit 1 asks you to describe the public health nursing role for a defined population, using the core functions of public health. Expect to define the population, explain how population-focused practice differs from individual care, apply assessment, policy development and assurance to that population, place the role among other services and set priorities. Many versions ask you to cite the APHA definition of public health nursing or the essential public health services. Check whether your section wants a geographic population or allows a population defined by condition or setting. A specific population with a number attached makes the brief concrete. Saying what the role is not helps as much as saying what it is, since public health nurses are often pulled toward clinic work alone.
Inside the NU 655 Unit 1 example
The brief opens with the population: age range, county size and the number of children. A short section explains the shift from patient to population, using the parallel between assessing one child and assessing a group. The core functions section takes each function in turn and gives a concrete example for this population, such as using registry data for assessment and working with clinics on reminder systems for assurance. A section places the nurse among colleagues in the health department and partners outside it. The section on what the role is not prevents the brief from collapsing into clinic duty. The priorities section names three tasks for the first year, each tied to a core function. Each claim rests on a national source.
Reading the NU 655 Unit 1 rubric
Herzing's rubric for the role brief usually covers the definition of the population, the explanation of population-focused practice, the application of core functions, the placement of the role, priorities and writing. Population points reward a defined group with size and boundaries. The core functions criterion carries the most weight; graders want each function shown in action for this population, not defined in general terms. Population-focused practice points go to a clear contrast with individual care. Placement criteria look for awareness of other services and partners. Priorities earn credit when they are specific and tied to functions. The APHA Public Health Nursing Section definition and the Institute of Medicine's 1988 report belong in the APA 7 list.
Common NU 655 Unit 1 mistakes, and how to avoid them
Role briefs in Unit 1 commonly lose points by describing public health nursing as clinic work, such as giving vaccines, without the assessment and policy functions. Another frequent problem is a population too vague to plan for, such as children in the community. Students often define the core functions without applying them. The shift from individual to population is mentioned but not explained. Other services are ignored, so the nurse appears to work alone. Priorities are general, such as improve health outcomes. Finally, attach numbers to the population, since a role brief that never says how many people the nurse serves or where they live is hard to grade.

NU 655 Unit 1 questions, answered
Does the population have to be a geographic area?
Not necessarily. A shared exposure, an age band, a workplace or a condition can bound a group just as well, and sometimes better, because the response follows the boundary. What matters is that the definition lets somebody count who is inside it and find where they are. If your instructions name a setting, use that and state the boundary you drew within it.
How much theory belongs in the brief?
Enough to give the practice a frame and no more. Name the model your instructions point at, then spend the space on what the nurse does inside it, because application is where the credit sits. Long summaries of public health history read as filler in a document meant to establish a role, and they crowd out the examples that make the role visible.
Can I write about the agency where I work?
In many sections that is welcome and it produces a sharper brief, since you know which partner actually answers the phone. Check the instructions, keep anything not publicly available out of the file, describe colleagues by role, and remember that real community figures or client details you have access to are yours to handle rather than material for an example.
