Mixed Deck — All CEAS Topics Flashcards

What is the primary purpose of a task analysis during a CEAS ergonomic assessment?

Answer: Identify and document the physical demands, frequency, and duration of each job task

Task analysis systematically breaks down job duties to identify physical demands, awkward postures, and exposure durations that drive ergonomic risk.

Which risk response strategy involves reducing the likelihood or impact of a risk?

Answer: Risk mitigation

Risk mitigation involves taking proactive steps to reduce either the probability of a risk occurring or its potential impact if it does occur.

When a worker holds a load at arm's length rather than close to the body, the primary biomechanical effect on the lumbar spine is:

Answer: Increased spinal moment (torque) due to a greater moment arm

A longer moment arm multiplies the torque that spinal muscles must generate to maintain balance, greatly increasing lumbar compressive and shear forces.

What is a key performance indicator (KPI) in quality management?

Answer: A measurable value that demonstrates how effectively objectives are being achieved

KPIs are quantifiable measurements that demonstrate how effectively an organization or process is achieving its key quality objectives.

Which body region is assessed most frequently during computer workstation ergonomic evaluations?

Answer: Neck and upper extremities

Computer work primarily stresses the neck, shoulders, arms, wrists, and hands, making upper-extremity and neck assessment the focus of most workstation evaluations.

The Strain Index is an ergonomic assessment tool primarily used to evaluate risk for disorders of which body region?

Answer: Distal upper extremity (hand, wrist, forearm)

The Strain Index was developed to quantify risk of distal upper extremity disorders based on factors like exertion, duration, and posture.

When a CEAS specialist recommends a document holder, what is the primary purpose?

Answer: Position source documents at the same height and distance as the monitor to reduce neck rotation and flexion

A document holder aligned with the monitor eliminates repeated neck rotation and vertical gaze shift between desk and screen, reducing cervical strain.

What is a root cause analysis used for?

Answer: To identify the underlying cause of a problem rather than just addressing symptoms

Root cause analysis is a systematic method used to identify the fundamental underlying cause of a problem, enabling solutions that prevent recurrence rather than just treating symptoms.

What is delegation in the context of team management?

Answer: Assigning tasks and authority to team members while maintaining accountability

Delegation involves assigning tasks and appropriate authority to team members while the leader maintains overall accountability for outcomes and provides necessary support.

What is the appropriate action when discovering a colleague has violated professional standards?

Answer: Report through proper channels as outlined in the code of ethics

Professional standards require reporting violations through proper channels to protect the public and maintain the integrity of the profession.

After implementing ergonomic interventions at a workstation, what is the most important follow-up action for a CEAS specialist?

Answer: Conduct a post-intervention assessment to verify effectiveness and worker acceptance

Post-intervention follow-up confirms that changes reduced risk factors, verifies correct use by the worker, and identifies any remaining or new concerns.

What is the Plan-Do-Check-Act (PDCA) cycle used for?

Answer: Continuous improvement of processes and practices

The PDCA cycle is a systematic approach to continuous improvement where processes are planned, implemented, evaluated, and refined in an ongoing cycle.

What is the ergonomic benefit of a negative-tilt keyboard tray?

Answer: Promotes neutral or slightly extended wrist posture by angling the keys away from the user

A negative tilt (front of keyboard higher than the back) encourages a neutral or slightly extended wrist position, reducing flexion and carpal tunnel pressure.

Which keyboard placement measurement is most important to assess upper-extremity ergonomics?

Answer: Elbow angle and wrist alignment relative to keyboard height

Elbow angle (ideally 90–110°) and neutral wrist alignment are the primary indicators of appropriate keyboard height in ergonomic assessments.

Which of the following muscles is NOT part of the rotator cuff?

Answer: Deltoid

The rotator cuff comprises supraspinatus, infraspinatus, teres minor, and subscapularis; the deltoid is a large, superficial shoulder muscle with a separate function and origin.

How many task variables does the NIOSH Lifting Equation use to calculate the Recommended Weight Limit (RWL)?

Answer: Six

The NIOSH Lifting Equation applies six multipliers — horizontal, vertical, distance, asymmetry, frequency, and coupling — to calculate the RWL.

Forearm pronation results in the palm facing:

Answer: Downward (posteriorly in anatomical position)

Pronation rotates the radius over the ulna so the palm faces downward (posteriorly), the opposite of supination; sustained pronation during keyboard use is an ergonomic risk factor.

Lateral epicondylitis ('tennis elbow') involves degeneration of the common tendon origin at the lateral epicondyle, primarily affecting which muscle group?

Answer: Wrist extensors

Lateral epicondylitis affects the common extensor tendon origin — most often the extensor carpi radialis brevis — at the lateral epicondyle of the humerus.

What is the primary objective of Certified Ergonomics Assessment Specialist certification?

Answer: To validate professional competence in certified ergonomics assessment specialist

The Certified Ergonomics Assessment Specialist certification validates that professionals have demonstrated competence and knowledge in their field.

What is the most important element of effective professional communication?

Answer: Clarity and accuracy of the message tailored to the audience

Effective professional communication requires clarity and accuracy, with the message tailored to the audience's level of understanding and needs.
