Community and Public Health Nursing
Core concepts
Community health questions test population-level thinking: levels of prevention, epidemiology basics, screening principles, health education, and the nurse's role in outbreak response and immunisation programmes. Know incidence versus prevalence, sensitivity versus specificity, and the difference between primary, secondary, and tertiary prevention.
Traps to expect
- Levels of prevention: immunisation and health education are primary; screening is secondary; rehabilitation and support groups are tertiary.
- Incidence versus prevalence: incidence counts new cases over a period; prevalence counts all existing cases at a point in time.
- Screening criteria: a good screening test is for a serious, treatable condition, is acceptable to the population, and has an agreed follow-up pathway.
- Outbreak steps: confirm and investigate before implementing control measures.
- Cultural competence: adapt education to language, literacy, and beliefs rather than delivering standard scripts.
Worked example
A clinic reports a rise in new hepatitis cases over one month. This is an increase in incidence, not prevalence. The community nurse's first step is to verify the diagnosis and investigate the source, then implement control measures and education, and finally evaluate the effect.
Study approach
For every intervention, ask: does this prevent the disease, detect it early, or reduce its consequences? That single question resolves most classification items.
