What the Course Entails and Exam Details

Preparing for the COHN exam requires mastering a comprehensive body of knowledge that spans multiple critical domains of occupational health nursing. The exam blueprint covers several key areas of practice, ensuring that certified nurses can effectively manage the diverse needs of an workforce. Candidates must understand the fundamentals of direct clinical care, including the assessment and treatment of work-related and non-work-related injuries and illnesses. They must also be proficient in case management, coordinating care for injured workers to facilitate a safe and timely return to work. Other vital domains include risk management, where nurses identify workplace hazards through ergonomics, industrial hygiene, and environmental assessments. The curriculum also delves into regulatory and legal compliance, ensuring nurses can navigate complex laws like OSHA and workers' compensation. Furthermore, you must possess strong program management and quality assurance skills to develop and evaluate effective wellness, education, and disease management programs that serve both the employees and the organization's business objectives.

• Scored Questions: Out of the 160 questions, only 135 are scored.
