Nursing study guide
Community + public health nursing
Use population data, prevention, equity, preparedness, and coordination to improve health beyond one encounter.
Population lens
Ask who is affected, who is missing, what conditions shape risk, and which community assets can help.
Nursing lens
Assess access, prevention, safety, communication, coordination, and the patient or community priorities.
Equity
Do not treat a social barrier as nonadherence; identify the barrier and connect practical support.
Population assessment
Community strengths and needs belong in the same picture
Start with people, place, data, services, history, and the priorities named by the community.
Data
Population, morbidity/mortality, utilization, environment, housing, food, education, work, transport, safety, access, and inequity patterns.
Assets
Residents, culture, mutual aid, schools, faith groups, clinics, public health, emergency services, nonprofits, and trusted leaders.
Process
Define the population, collect quantitative and qualitative data, validate with community members, prioritize together, act, and evaluate.
Epidemiology
Describe who, where, when, and what changed
Rates need a denominator and an appropriate comparison.
| Measure | Question | Nursing use |
|---|---|---|
| Incidence | How many new cases occurred in the population during the period? | Detect emerging risk and evaluate prevention. |
| Prevalence | How many people currently have the condition? | Plan ongoing services and resources. |
| Attack rate | What proportion of the exposed group became ill in an outbreak? | Compare groups and support source investigation. |
| Risk / rate comparison | How do groups differ, and could access or measurement explain part of it? | Avoid causal claims from association alone; examine inequity and bias. |
Prevention
Match the intervention to the point in the disease course
Population and individual prevention reinforce each other.
Primary
Prevent onset: immunization, safer environments, injury prevention, clean air/water, education, and policy.
Secondary
Detect early: screening and case finding with an evidence-based follow-up pathway.
Tertiary
Reduce complications: chronic-disease management, rehabilitation, support, and recurrence prevention.
Evaluate
Measure reach, uptake, outcome, unintended effects, and whether benefits were equitable.
Health equity + SDOH
Ask what conditions make the healthy choice possible
Social needs are individual experiences; social determinants are broader conditions and systems.
Domains
Economic stability, education access/quality, healthcare access/quality, neighborhood/built environment, and social/community context.
Nursing response
Screen respectfully when a response can lead to support; obtain consent, protect privacy, avoid stigma, and document actionable barriers.
Equity check
Who can access the intervention? Who bears cost or risk? Are language, disability, trust, geography, hours, or documentation barriers present?
Vulnerable populations
Risk grows when exposure, susceptibility, and barriers overlap
Do not define a person only by a population label.
Examples
People experiencing homelessness, disability, poverty, rural isolation, language barriers, migration, incarceration, violence, pregnancy, extremes of age, or chronic illness may face different barriers.
Trauma-informed approach
Prioritize safety, trust, choice, collaboration, transparency, and avoidance of unnecessary retraumatization.
Access plan
Use interpreters, accessible communication, transportation/housing/food resources, low-barrier follow-up, medication access, and warm handoffs.
Disaster preparedness + triage
Protect the greatest number while preserving dignity and communication
Use the incident-command and triage system adopted by the jurisdiction and facility.
Prepare
Know hazards, personal/family plan, role, communication backup, PPE, evacuation/shelter, medication continuity, and populations needing access/function support.
Triage
Perform rapid repeated sorting with the approved system; priorities can change after treatment, movement, or resource change.
Nursing actions
Scene safety, lifesaving interventions within role, identification/tracking, infection control, documentation, reunification, psychological first aid, and escalation.
Ethics
Use transparent policy and team command; do not improvise exclusion rules or promise unavailable resources.
Care coordination
Close the loop across people, settings, and time
A referral is not complete until responsibility, information, access, and follow-up are clear.
At transition
Medication reconciliation, pending results, red flags, self-management, equipment, appointments, transport, affordability, contact, and who owns the next step.
Case management
Assess complex needs, align goals, coordinate services, advocate, monitor outcomes, and reduce duplicated or missed care.
Cross-links
Apply population and access themes across pediatric, mental-health, and genetic-disorder nursing care.
