1. What is the primary goal of ergonomics in the workplace?
A. Increase production speed
B. Reduce labor costs
C. Fit the job to the worker
D. Eliminate all physical activity
C. Fit the job to the worker
Ergonomics focuses on designing tasks, tools, and environments to
match the capabilities and limitations of workers. This reduces injury
risk and improves efficiency without compromising safety.
2. Which body system is most commonly affected by poor
ergonomic practices?
A. Cardiovascular system
B. Musculoskeletal system
C. Digestive system
D. Endocrine system
B. Musculoskeletal system
Poor ergonomic conditions often lead to musculoskeletal disorders
(MSDs), affecting muscles, tendons, ligaments, nerves, and joints due to
repetitive stress or awkward postures.
, 3. Which of the following is a common risk factor for
musculoskeletal disorders?
A. Adequate lighting
B. Neutral posture
C. Repetitive motion
D. Scheduled rest breaks
C. Repetitive motion
Repetitive motion without sufficient recovery time strains tissues and
increases the likelihood of cumulative trauma injuries.
4. Neutral posture is best described as:
A. A rigid, upright stance
B. A posture minimizing joint stress
C. Any seated position
D. A reclining position
B. A posture minimizing joint stress
Neutral posture aligns joints naturally, reducing strain on muscles,
tendons, and ligaments.
5. Which ergonomic intervention is most effective for reducing
lifting injuries?
A. Increasing workload
B. Providing lifting training only
C. Engineering controls such as lift assists
D. Encouraging faster task completion
C. Engineering controls such as lift assists
Engineering controls physically reduce exposure to hazards and are
more reliable than administrative controls or training alone.
6. The term “cumulative trauma disorder” refers to:
A. Sudden traumatic injury
, B. Long-term repetitive strain injury
C. Chemical exposure injury
D. Acute fracture
B. Long-term repetitive strain injury
Cumulative trauma disorders develop gradually due to repeated
microtrauma over time.
7. Which tool assesses upper limb ergonomic risk?
A. NIOSH Lifting Equation
B. RULA
C. OSHA 300 Log
D. BMI Scale
B. RULA
Rapid Upper Limb Assessment (RULA) evaluates postural risks to upper
extremities during work tasks.
8. The primary purpose of the NIOSH Lifting Equation is to:
A. Measure cardiovascular endurance
B. Determine safe lifting limits
C. Evaluate lighting conditions
D. Calculate BMI
B. Determine safe lifting limits
The NIOSH Lifting Equation provides a recommended weight limit based
on task variables to reduce injury risk.
9. Awkward postures increase injury risk because they:
A. Improve circulation
B. Reduce muscle demand
C. Increase biomechanical stress
D. Strengthen ligaments
