American Society for Clinical Pathology (ASCP) Technologist in Cytogenetics certification (ASCP CG) Practice Test

What can a technologist do to reduce the risk of repetitive motion injuries when analyzing data on a computer?

1. Keep both hands on the keyboard at all times

2. Support the arm that moves the mouse

3. Limit sitting time by only standing during breaks

4. Use a wrist strap

The correct answer is: Support the arm that moves the mouse

Supporting the arm that moves the mouse is a key strategy for reducing the risk of repetitive motion injuries, as it helps maintain proper ergonomics while using a computer. By providing support to the arm, the technologist can minimize strain on the shoulder, wrist, and forearm, which are commonly affected by repetitive movements associated with prolonged mouse usage. When an arm is unsupported, it can lead to tension and discomfort, especially during extended periods of data analysis, contributing to conditions such as carpal tunnel syndrome or tendonitis. By ensuring that the arm is supported, either by using a properly designed mouse pad with wrist support or an ergonomic chair with adjustable armrests, the technologist can promote a more natural posture, thereby reducing the risk of developing these types of injuries. Other strategies, while they may have some effect, do not address the underlying ergonomic issues as directly or effectively. Keeping both hands on the keyboard may limit the use of the mouse but doesn’t necessarily prevent strain. Limiting sitting time is important for overall health but does not specifically focus on the mechanics of using the mouse. A wrist strap could provide some support but does not substitute for proper arm and shoulder positioning during extended computer use.
