Health Promotion and Disease Prevention
Levels of prevention
Primary prevention stops disease before it starts (immunizations, hand hygiene, helmet and seat-belt education, tobacco and vaping prevention, nutrition and physical activity policy). Secondary prevention detects disease early (screening, BMI surveillance, dental screening). Tertiary prevention limits disability in students already affected (asthma action plans, diabetes self-management support, individualized education). Many exam distractors are simply prevention-level mismatches.
Core content
- Immunizations: know school-entry requirements, conditional enrollment, medical versus religious/personal exemptions under state law, exclusion during outbreaks, and the nurse's role in surveillance and recall - not in judging exemptions.
- Infection control: standard precautions for all blood and body fluids, hand hygiene as the single most effective measure, respiratory etiquette, and exclusion criteria based on transmission (e.g., fever with rash, pertussis until treated).
- Health education and policy: the WSCC (Whole School, Whole Community, Whole Child) model, the district wellness policy, and the coordinated school health team.
- Behavior change: motivational interviewing rather than lecturing, teach-back for health literacy, and culturally tailored materials.
Traps
Confusing primary and secondary prevention. Assuming the nurse can waive an immunization "because it is easier." Forgetting that adolescent confidential services (reproductive health, substance use) follow state minor-consent rules. Treating health education as a one-time assembly instead of a planned curriculum with measurable objectives.
Rule of thumb
Ask: does this action keep the disease from occurring (primary), find it early (secondary), or reduce its impact (tertiary)? Then ask whether the nurse has legal authority and preparation to do it. Health promotion is population-based; health education is one tool within it, and every program needs an outcome measure.
