COHN Health Promotion and Prevention Questions and Answers

Question 1

An Occupational Health Nurse (OHN) is developing a wellness program for a manufacturing company. The primary goal is to prevent the onset of new health conditions among the workforce. Which of the following interventions best represents a primary prevention strategy?

Accepted Answer

Offering workshops on stress management and healthy nutrition.

Answer

Primary prevention aims to prevent disease or injury before it ever occurs. Offering educational workshops on healthy behaviors like stress management and nutrition is a classic example of a primary prevention strategy designed to prevent the initial occurrence of health problems like hypertension, obesity, and related chronic diseases.

Question 2

A worker in a noisy factory reports tinnitus. The OHN's assessment confirms the worker has been wearing their assigned earplugs consistently but incorrectly. According to the hierarchy of controls, which of the following actions would be the MOST effective long-term solution to protect this worker and others from noise-induced hearing loss?

Accepted Answer

Installing sound-dampening enclosures around the loudest machinery.

Answer

The hierarchy of controls prioritizes methods to eliminate or reduce hazards. Engineering controls, which physically isolate people from the hazard, are more effective than administrative controls or personal protective equipment (PPE). Installing sound-dampening enclosures is an engineering control that reduces the noise at its source, offering a more reliable and protective solution than relying on worker behavior like PPE use (earplugs) or administrative changes (job rotation).

Question 3

When designing a comprehensive workplace wellness program, which component is crucial for identifying the specific health needs and risks of the employee population to ensure the program is targeted and effective?

Accepted Answer

Conducting aggregate health risk appraisals and biometric screenings.

Answer

A successful wellness program begins with understanding the specific needs of the workforce. Conducting health risk appraisals (HRAs) and biometric screenings provides valuable aggregate data on health risks, such as high blood pressure, cholesterol, and stress levels, allowing the OHN to tailor interventions and prioritize resources effectively.

Question 4

An OHN implements a mandatory hearing conservation program for all employees exposed to noise levels at or above the OSHA action level. This program includes baseline and annual audiograms, training, and provision of hearing protection. This entire program is an example of which level of prevention?

Accepted Answer

Secondary prevention

Answer

Secondary prevention focuses on the early detection and treatment of disease to slow its progression. A hearing conservation program with regular screening tests (audiograms) is designed to detect early signs of hearing loss, allowing for timely intervention to prevent further damage. While it has primary prevention elements (training, PPE), its core function of early detection through screening places it firmly in the secondary prevention category.

Question 5

An office manager asks the OHN for guidance after several employees complain of wrist and shoulder pain. The OHN's initial action should be to promote health and prevent further injury by:

Accepted Answer

Conducting ergonomic assessments of the employees' workstations.

Answer

The role of the OHN includes assessing the workplace to identify potential hazards and health risks, including ergonomic risks. Before implementing controls or recommending treatment, the OHN must first assess the root cause of the problem. An ergonomic assessment will identify specific risk factors in the workstation setup (e.g., chair height, monitor position) that can be corrected to prevent further injury.
