Community and Public Health Nursing
Core concepts
Community health focuses on populations rather than individuals. Understand the levels of prevention: primary (prevent disease before it occurs, such as immunizations), secondary (early detection, such as screening), and tertiary (rehabilitation and limiting disability). Know epidemiology basics: incidence versus prevalence, attack rate, and outbreak investigation steps. Community assessment includes windshields surveys and data sources. Public health nursing roles include case finding, outreach, and health education. Social determinants of health and health equity are increasingly tested. Disaster nursing covers triage and mass casualty response. Reportable communicable diseases and contact tracing belong here.
Traps to watch
The most common trap is mislabeling a prevention level. Screening is secondary, not primary. Another trap is confusing incidence (new cases over time) with prevalence (all existing cases). Questions may ask about the community as client, so an answer focused on one individual is wrong. Disaster triage items test the principle of doing the greatest good for the greatest number, which differs from individual emergency care. Watch for questions about culturally congruent care and health literacy.
Worked rule of thumb
Label the prevention level before choosing an answer. Ask: does this stop disease before it starts (primary), find it early (secondary), or reduce complications (tertiary)? Example: a blood pressure screening fair is secondary prevention, while teaching about low-sodium diets to prevent hypertension is primary.
