Final answer:
The nurse can protect against self-injury while working on a computer by maintaining proper body mechanics and ergonomics. This includes correct chair height, monitor position, and neutral wrist positioning.
Step-by-step explanation:
The nurse protects against self-injury when working with the computer by maintaining good body mechanics when sitting at the computer.
This includes making sure that the chair is at the correct height, the monitor is at eye level, and the keyboard and mouse are positioned to allow for the wrists to remain in a neutral position.
These precautions help to prevent musculoskeletal disorders and eye strain, which can result from improper workstation ergonomics.
In a broader context, a human factors psychologist concerned with an office workstation might focus on issues such as height of the chair to ensure comfort and reduce the risk of injury.
By practicing safe behaviors, individuals can protect their nervous system and overall health from the potential harms associated with prolonged computer use.
