1.
Repetitive motion injuries are caused by ___________ exposure to a combination of factors.
Correct Answer
C. Prolonged
Explanation
Repetitive motion injuries are caused by prolonged exposure to a combination of factors. This means that these injuries occur over a long period of time, rather than immediately or intermittently. Prolonged exposure to repetitive motions, such as typing or lifting heavy objects, can lead to strain and damage to the muscles, tendons, and nerves. This type of injury often develops gradually and worsens over time, making it important to take breaks, use proper ergonomics, and seek treatment to prevent further damage.
2.
Most RMIs occur to the ______________.
Correct Answer
D. All of the above
Explanation
RMIs (Repetitive Motion Injuries) can occur to various parts of the body due to repetitive movements or overuse. Upper extremities such as hands, wrists, and arms are commonly affected by RMIs like carpal tunnel syndrome. Back injuries can occur due to repetitive lifting or bending motions. Neck injuries can result from repetitive movements or poor posture. Therefore, all of the above options are correct as RMIs can occur in the upper extremities, back, and neck.
3.

Correct Answer
B. False
Explanation
The statement "Ergonomics is the science of safely fitting the worker to the work" is incorrect. Ergonomics is actually the science of designing and arranging products, systems, and environments to fit the needs and capabilities of the people who use them. It focuses on optimizing human well-being and overall system performance. Therefore, the correct answer is False.
4.
There are six "rules" for mouse use. Which of the following is not one of them?
Correct Answer
C. Rest your wrist on a stationary surface whenever using a mouse.
Explanation
Resting your wrist on a stationary surface whenever using a mouse is not one of the six "rules" for mouse use. The other options listed are all important guidelines for using a mouse correctly, such as holding the mouse loosely, keeping wrists in a neutral position, and using your whole arm and shoulder to move the mouse. Resting the wrist on a stationary surface can lead to strain and discomfort in the long run.
5.
To avoid repetitive motion injuries it is advised that you take a break periodically, alternate tasks, switch hands, or rotate work activities.
Correct Answer
A. True
Explanation
Taking breaks periodically, alternating tasks, switching hands, or rotating work activities are all effective strategies to prevent repetitive motion injuries. These actions help to reduce the strain on specific muscles and joints, allowing them to rest and recover. By incorporating these practices into your work routine, you can minimize the risk of developing repetitive motion injuries such as carpal tunnel syndrome or tendonitis. Therefore, the statement is true.
6.
Stressing your wrist can occur with gripping, grasping, or lifting with just the thumb and forefinger.
Correct Answer
A. True
Explanation
Stressing your wrist can indeed occur with activities such as gripping, grasping, or lifting objects using only the thumb and forefinger. These actions can put strain on the tendons and muscles in the wrist, leading to wrist pain or discomfort. Therefore, the statement "Stressing your wrist can occur with gripping, grasping, or lifting with just the thumb and forefinger" is true.
7.
In laying out your work station, which of the following is/are recommended:
Correct Answer
D. A and B
Explanation
In order to have an organized and efficient work station, it is recommended to place equipment that is frequently used within easy reach. This ensures that the necessary tools are readily accessible and saves time and effort. Additionally, avoiding clutter on the work surface helps to maintain a clean and organized workspace, reducing distractions and increasing productivity. Therefore, the correct answer is A and B.
8.
The first step to workspace ergonomics is to adjust your monitor so the top of the screen is at eye level.
Correct Answer
B. False
Explanation
The correct answer is False. The first step to workspace ergonomics is not to adjust the monitor so the top of the screen is at eye level. While it is important to position the monitor at eye level, the first step to workspace ergonomics is actually to adjust the chair and desk height so that your feet are flat on the floor and your knees are at a 90-degree angle.
9.
The three primary areas in an office environment that should be ergonomically adjusted are:
Correct Answer
C. Chair, Monitor and Keyboard placement, Environment and Workspace Considerations
Explanation
The correct answer is Chair, Monitor and Keyboard placement, Environment and Workspace Considerations. This answer is correct because it includes all the essential elements that should be ergonomically adjusted in an office environment. The chair, monitor, and keyboard placement are crucial for maintaining proper posture and reducing strain on the body. Additionally, considering the overall environment and workspace factors such as lighting, temperature, and noise levels are important for creating a comfortable and productive work environment.
10.
Adjusting the office chair is a key step in proper monitor and keyboard placement.
Correct Answer
A. True
Explanation
Adjusting the office chair is indeed a key step in proper monitor and keyboard placement. This is because the height and position of the chair can greatly affect the ergonomics of the workstation. By adjusting the chair to the correct height and ensuring proper support for the back and arms, the user can maintain a comfortable and healthy posture while working. This, in turn, helps to prevent strain on the neck, back, and wrists, and promotes better productivity and overall well-being.
