Which is the most common occupational hazard of a computer worker?

Appeared in: AIIMS Raipur - 2017 (Shift-3)

Explanation

Carpal tunnel syndrome is the most frequent occupational injury among computer users.
It is a repetitive strain injury caused by compression of the median nerve in the wrist.
The primary cause is prolonged, repetitive hand and wrist movements, characteristic of typing and mouse use.
Symptoms include numbness, tingling, and pain in the hand and fingers, which can progress to weakness if untreated.

Option A: There is no direct causal link established between typical computer use and the development of cancer.
Option B: Computer use in an office environment does not involve exposure to dust, fumes, or pathogens that cause lung disease.
Option C: While computer use can cause eye strain, it does not lead to the formation of cataracts, which is a clouding of the eye's lens.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Occupational Health Hazards as background academic context rather than a clinical decision trigger.
Nurses, especially in occupational health settings, are pivotal in educating employees about ergonomic practices to prevent repetitive strain injuries like Carpal Tunnel Syndrome.
Early identification of symptoms and intervention are crucial. A nurse's assessment can help facilitate timely referral to a specialist, preventing long-term nerve damage and disability.
What if? - If a computer worker also has a pre-existing condition like rheumatoid arthritis or diabetes, their risk for developing Carpal Tunnel Syndrome is significantly higher. A nurse would need to provide more intensive education and monitoring for this individual.

How to Approach the Question

First, identify the core of the question: it asks for the 'most common' hazard for a 'computer worker'.
Analyze the specific activities of a computer worker: this primarily involves sitting, typing, and using a mouse, which are repetitive hand and wrist movements.
Evaluate each option based on these activities.
Cancer and Lung Disease are serious conditions but are not caused by the physical actions of using a computer. Eliminate these.
Cataracts are an eye condition, and while eye strain is a computer-related issue, it doesn't cause cataracts. Eliminate this option.
Carpal tunnel syndrome is directly related to repetitive wrist motion, a key activity in computer work. This makes it the most plausible and common hazard.
