Clinical meaning
Occupational health nursing focuses on preventing work-related injuries and illnesses, promoting worker health, and managing workplace health programs. The hierarchy of controls guides hazard management: elimination (remove the hazard), substitution (replace with less hazardous), engineering controls (redesign equipment), administrative controls (change work practices), and PPE (personal protective equipment) as the last resort. Common occupational hazards include chemical exposures (solvents, dusts, fumes), physical hazards (noise, vibration, radiation), biological hazards (bloodborne pathogens, TB), ergonomic risks (repetitive strain, manual handling), and psychosocial factors (workplace violence, burnout). Workers' compensation provides medical treatment and wage replacement for work-related injuries. The Occupational Safety and Health Administration (OSHA) sets and enforces workplace safety standards. Return-to-work programs facilitate safe transition from disability to productive work through modified duties and gradual return.
Exam relevance
Risk factors: - Repetitive motion tasks causing musculoskeletal disorders - Chemical exposure without adequate ventilation or PPE - Excessive noise exposure causing hearing loss (>85 dB threshold) - Shift work disrupting circadian rhythms and increasing error risk - Workplace violence particularly in healthcare and social services
