Final answer:
The pain and ache experienced by the nurse is most likely due to poor body mechanics while using the computer, leading to conditions such as tendinitis and carpal tunnel syndrome.
Step-by-step explanation:
The nurse's pain in the right wrist and the ache around the shoulders and back, after transitioning to a desk job, are most likely caused by poor body mechanics when using the computer.
This is due to performing the same movements repeatedly which can lead to musculoskeletal disorders such as tendinitis and biomechanical problems like carpal tunnel syndrome.
Consistent use of poor posture, especially while using a computer for extended periods, can result in neck pain (Pain in the Neck), which is a common issue for many adults each year. Improper body mechanics while working at a desk can strain muscles and create discomfort that worsens over time if not addressed properly.
