Ask ten people to define "Family The people a person identifies as family — blood, marriage, partnership, adoption, or chosen kin Full entry →" and you will get ten different answers — and that is exactly the point. In nursing, family is who the person says it is: the people bound by blood, marriage, adoption, partnership, or commitment who function as the person's support system. A family can be two people or twenty, can span generations or be a chosen family of close friends, and can change over time. What makes a group a family in the healthcare sense is not a legal definition but a function: these are the people who love, care for, and are affected by the patient.
This topic introduces the basic building blocks nurses use when the "unit of care" is bigger than one person: how to think about family structure (who makes up the family), family functions (what families do), the three ways nurses view the family (as context, as client, or as a system), and the two assessment tools that make family data visible — the Genogram Multi-generational diagram of family relationships, health patterns, and roles Full entry → and the Ecomap Diagram of the family's connections to outside systems and resources Full entry →. Later topics in this chapter build on these foundations to explain how family dynamics influence health outcomes and what the nurse's role is in caring for the family unit.
Why this matters
Almost no patient arrives at care alone. Families influence whether a person takes medication, keeps appointments, changes diet, or recovers at home — and a person's illness, in turn, reshapes the family: roles shift, finances strain, caregivers burn out. When nurses understand family concepts, they can:
- Assess realistically: knowing who the family is (not just who is in the waiting room) reveals who needs teaching, who is the caregiver, and who must be consulted for discharge planning.
- Educate effectively: teaching a family member who will administer care at home is different from teaching the patient alone.
- Recognize strain: identifying caregiver burden and family conflict early prevents crises after discharge.
- Provide family-centered care: treating the family as part of the care team improves outcomes and honors the patient's world — which is also what most patients say they want.

Core Concepts
What counts as a family
Nursing's working definition is deliberately broad: family members are who the person identifies as family. This includes blood relatives, spouses and partners, adoptive and foster family, in-laws, step-relations, and chosen family (close friends who function as kin). Two practical consequences:
- Ask, don't assume. "Family" cannot be inferred from a last name, a wedding ring, or who looks related. A standard question — "Who are the people closest to you?" — opens the door.
- Legality is not the same as family. A person's healthcare decision-maker is determined by law (see Chapter 36 on legal considerations), but caregiving, visiting, and support are shaped by who actually functions as family. Both matter; they are different questions.
Family structures
Structure describes the makeup of the family. Common forms include:
- Nuclear family Parents/partners and their children in one household Full entry →: two parents (or partners) and their children.
- Extended family Relatives beyond the nuclear unit who participate in family life and care Full entry →: relatives beyond the nuclear unit — grandparents, aunts, uncles, cousins — living nearby or in the same household, often sharing caregiving.
- Single-parent family: one parent raising children, sometimes with support from extended family or community.
- Blended (step) family: partners with children from previous relationships forming a new household.
- Multigenerational family: three or more generations under one roof (increasingly common as elders and adult children live together).
- Same-sex parent families, childless families, and communal/group households round out a picture that no single template captures.
Two cautions: structures are descriptions, not diagnoses — no structure is inherently healthy or unhealthy — and families shift over time (divorce, remarriage, children leaving, elders moving in), so the structure the nurse assessed last admission may not be the structure today.
Functions of the family
What does a family do? Nursing textbooks typically group family functions into:
- Physical maintenance: food, shelter, clothing, and meeting members' basic needs.
- Socialization: teaching children (and newcomers) language, values, and social roles.
- Emotional support: affection, belonging, a place to be known and accepted.
- Economic support: pooling and managing resources; the family is often the first "safety net."
- Health-related functions: promoting health habits, monitoring illness, providing care when a member is sick, and navigating the healthcare system.
When a member is hospitalized, the family's other functions don't pause — they stretch. Recognizing that helps nurses see why families under strain may struggle to absorb new teaching or make decisions.
Family as context, client, or system
Nurses can view the family in three ways, and the right view depends on the situation:
- Family as context: the family is background — the nurse focuses on the individual patient but considers how the family affects that person's health (e.g., a patient whose family cooks traditional high-salt meals).
- Family as client: the family itself is the unit of care — every member is the focus (e.g., community health, family planning, a family coping with a genetic condition).
- Family as system Viewing the family as an interacting whole where change in one member affects all Full entry →: the family is an interacting whole whose parts affect one another — a change in one member ripples through everyone (e.g., a parent's new disability changes roles for the whole household). This view is the foundation of the frameworks in the next topic.
Assessment tools: genogram and ecomap
- Genogram: a multi-generational "family tree" diagram (usually three or more generations) showing relationships, marriages, children, deaths, and patterns of health and illness. It reveals hereditary risks, family roles, and relationship quality (close, distant, conflicted).
- Ecomap: a diagram of the family in the center surrounded by its connections to outside systems — school, work, church, healthcare, friends, social services — with lines showing the strength and direction of each connection. It reveals the family's resources and gaps.
Together they answer two questions every discharge plan needs: What runs in this family? and What does this family have to lean on? (The family assessment models used in practice, such as the Calgary Family Assessment Model, organize exactly these kinds of data.)
Common Confusions
| Do Not Confuse | With | Difference |
|---|---|---|
| Family | Household | A household is people sharing a dwelling; family is who the person identifies as kin — chosen family may not live together, and housemates may not be family |
| Family structure | Family function | Structure = makeup; function = what the family does. A "non-traditional" structure can function superbly, and a "traditional" one can be dysfunctional |
| Legal next of kin | Family | Law may designate a decision-maker, but caregiving and support come from whoever functions as family — nurses work with both |
| "A typical family" | A healthy family | There is no single normal structure; health depends on function, resources, and dynamics, not form |
| Nuclear family | The only real family | Nuclear is one structure among many; extended, blended, multigenerational, and chosen families are equally real |
| One genogram visit | A complete family picture | Families change (births, deaths, divorce, moves); reassess structure and supports over time |
Eli explains
The same idea, in plain words
Explain it like I’m 10
A family is the group of people who love and take care of each other — it can be parents and kids, grandparents, two dads, one mom, or close friends who feel like family. Families do important jobs: feeding and housing people, teaching kids, giving hugs and support, and helping when someone is sick. When a nurse takes care of someone who is sick, they also need to know who that person's family is, because the family is the team that will help them get better at home.
Worked example
Mr. Okafor, 62, is being discharged after a first heart event. The student's initial plan focuses on teaching Mr. Okafor alone about his medications and follow-up. The nurse instead asks one question — "Who are the people closest to you?" — and draws a quick genogram with the student. The picture changes everything:
- Structure: Mr. Okafor lives with his wife, their adult daughter, and the daughter's two children — a multigenerational household. His wife does the cooking.
- Patterns: two generations back, his father and an uncle both died of heart disease; his mother has diabetes. The genogram makes the family's health patterns visible — and prompts a conversation about screening for the adult children.
- Roles: the wife is the main cook and the daughter drives and manages appointments. Teaching the patient alone would have failed: the family holds the levers.
The ecomap adds the outside world: a mosque community that brings meals, a church-affiliated senior center, and a strained relationship with the primary care clinic (missed appointments in the past). The nurse's plan now includes the wife in dietary teaching, the daughter in appointment logistics, and a referral conversation about the clinic's transportation support. Same patient, same discharge — but the family concepts turned a generic handout into a plan the family could actually execute.
Key takeaways
- Family = who the person says it is. Broader than biology or law; ask, don't assume.
- Structure ≠ function. A family's makeup (nuclear, blended, multigenerational) does not determine how well it functions.
- Families perform physical, social, emotional, economic, and health functions — illness strains all of them.
- Three views of the family: as context (background), as client (unit of care), or as system (interacting whole) — choose per situation.
- Genogram = family tree + health/relationship patterns; ecomap = family's links to the outside world. Both are core assessment tools.
- Families change over time — reassess structure and support at every encounter, not just admission.
- Person-first and family-first language: "a family caring for a child with diabetes," not "a diabetic family."

6 review questions from the chapter. Try each one, then open the answer.
How should a nurse determine who a patient's "family" is?
Show answer
Ask — using a question like "Who are the people closest to you?" — because family is who the person identifies as family (blood, marriage, partnership, adoption, or chosen kin), not who looks related or who is legally recognized.
What are the three ways nurses view the family, and when is each appropriate?
Show answer
Family as context (the family is background influencing an individual patient's health), family as client (the family itself is the unit of care), and family as system (an interacting whole where change in one member affects all). The appropriate view depends on the situation and the care goals.
What is the difference between a genogram and an ecomap?
Show answer
A genogram is a multi-generational family tree showing relationships, roles, deaths, and health/illness patterns; an ecomap shows the family at the center connected to outside systems (work, school, church, healthcare, services) with the strength of each connection.
Why is Family structure The makeup of the family (nuclear, extended, single-parent, blended, multigenerational, etc.) Full entry → alone a poor predictor of family health?
Show answer
Because health depends on function — how well the family meets physical, emotional, social, and economic needs — not on its shape. Any structure can be healthy or strained; assess what the family does and the resources it has.
A patient's spouse is the legal decision-maker, but the patient's sister provides all daily care. Who should discharge teaching include, and why?
Show answer
Both — teaching must reach whoever provides daily care (the sister) and whoever holds legal decision-making authority (the spouse). Family structure, function, and legal roles are different questions with different answers, and a safe discharge plan needs all of them.
List three functions families perform that are directly relevant to health.
Show answer
Any three of: physical maintenance (food, shelter, clothing), socialization, emotional support, economic support, and health-related functions (health habits, monitoring illness, caregiving, navigating healthcare).
