Question 3: During a hazard walk-through, an ABOHN-certified nurse identifies that workers are exposed to silica dust above the permissible exposure limit. Her first priority action should be:
- Order N95 respirators immediately for all affected workers
- Document the finding and notify management with recommendations for engineering controls (Correct answer)
- File a complaint with OSHA on behalf of workers
- Conduct pulmonary function testing on all exposed workers
Correct answer: Document the finding and notify management with recommendations for engineering controls
Documenting findings and recommending engineering controls follows the hierarchy of controls and appropriate occupational health nursing advocacy channels before escalating to regulatory bodies.
Question 4: Which type of examination question format does the ABOHN certification exam exclusively use?
- True/False
- Essay
- Multiple-choice (single best answer) (Correct answer)
- Matching and drag-and-drop
Correct answer: Multiple-choice (single best answer)
ABOHN certification exams use single-best-answer multiple-choice questions, consistent with standardized professional credentialing exam formats.
Question 5: A company nurse holds both COHN-S and COHN-S/CM credentials. If she allows only the CM subspecialty to lapse while maintaining COHN-S, she will:
- Lose both credentials simultaneously
- Retain the COHN-S credential but lose the CM designation (Correct answer)
- Automatically revert to a basic COHN credential
- Be required to retake the COHN-S examination
Correct answer: Retain the COHN-S credential but lose the CM designation
The CM is a subspecialty add-on; its lapse affects only that designation while leaving the primary COHN-S credential intact.
Question 6: Which of the following best represents the primary purpose of ABOHN certification for occupational health nurses?
- Meeting OSHA's mandatory qualification requirements for workplace nurses
- Demonstrating professional competence and commitment to occupational health nursing (Correct answer)
- Replacing state RN licensure for nurses working in industrial settings
- Qualifying nurses to prescribe occupational health medications independently
Correct answer: Demonstrating professional competence and commitment to occupational health nursing
ABOHN certification is a voluntary credential that validates a nurse's specialized knowledge and commitment to excellence in occupational health nursing practice.
Question 7: An occupational health nurse wants to maintain COHN certification through professional achievement rather than retaking the exam. This recertification pathway is called:
- Examination waiver renewal
- Portfolio recertification
- Professional development recertification (Correct answer)
- Continuing competence verification
Correct answer: Professional development recertification
ABOHN offers a professional development recertification pathway where nurses accumulate required continuing education and professional activities instead of retaking the examination.
