Occupational Health Nursing Practice and Professional Role
The role and its boundaries
Occupational health nursing (OHN) applies the nursing process to a working population rather than to a single patient. Candidates must understand the scope-of-practice triangle: what the nurse may do independently (assessment, first aid, health teaching, surveillance testing, case management), what requires standing orders or written protocols from a physician or advanced practice provider, and what must be referred out (diagnosis, prescribing, definitive treatment). Know the AAOHN/ABOHN framework, the nursing process as applied to aggregates, and the ethical duties of confidentiality, advocacy, and dual loyalty when employer interests and worker interests diverge.
Core concepts to master
- Aggregate focus: the "client" is the workforce; you plan for groups, not just individuals.
- Primary, secondary, tertiary prevention and where each OHN activity fits.
- Roles: clinician, case manager, educator, consultant, researcher, change agent, leader.
- Confidentiality and recordkeeping: medical records are separate from personnel files; release requires authorization except where law mandates (e.g., OSHA access rights, workers' compensation).
- Collaboration with safety, HR, industrial hygiene, and management.
- Professional development: certification, continuing education, evidence-based practice.
Traps
Questions love to blur the independent/protocol/referral line. A nurse may perform a hearing test or spirometry under a protocol, but interpreting it as a diagnosis or clearing a worker for a specific job is often outside nursing scope. Another trap: choosing "report to the employer" when the correct answer is "protect confidentiality and report only aggregate or legally required information." Watch for answers that make the nurse the sole decision-maker on fitness-for-duty.
Rule of thumb
If an action requires a medical diagnosis, prescription, or a legal fitness determination, the nurse's role is assess, document, refer, and advocate - not decide.
