AIEHS Certified Ergonomics Assessment
CEAP Exam
**Question 1.** Which of the following best defines macro‑ergonomics?
A) Design of an individual’s chair and keyboard
B) Evaluation of an entire production system’s workflow
C) Adjustment of a worker’s posture while seated
D) Selection of a personal protective equipment size
Answer: B
Explanation: Macro‑ergonomics focuses on organizational and systemic factors such as
workflow, scheduling, and overall system design, rather than individual workstations.
**Question 2.** The most common site for work‑related carpal tunnel syndrome is:
A) The lateral epicondyle
B) The thoracic spine
C) The median nerve at the wrist
D) The lumbar vertebrae L4‑L5
Answer: C
Explanation: Carpal tunnel syndrome results from compression of the median nerve as it passes
through the carpal tunnel at the wrist.
**Question 3.** In the “workplace athlete” concept, which preventive measure is analogous to
an athlete’s warm‑up?
A) Annual health questionnaire
B) Pre‑shift stretching routine
C) Mandatory overtime
D) Fixed‑height workstations
Answer: B
, AIEHS Certified Ergonomics Assessment
CEAP Exam
Explanation: A pre‑shift stretching routine prepares muscles and joints for activity, similar to an
athlete’s warm‑up to reduce injury risk.
**Question 4.** Which anatomical structure is most likely to be strained during repetitive
overhead reaching?
A) Patellar tendon
B) Rotator cuff muscles
C) Plantar fascia
D) Biceps brachii tendon
Answer: B
Explanation: Overhead reaching places repetitive stress on the rotator cuff, which stabilizes the
shoulder joint.
**Question 5.** The primary purpose of OSHA’s W‑1 form is to:
A) Calculate the Lifting Index for heavy loads
B) Conduct a quick screen for potential ergonomic problems
C) Measure hand‑arm vibration exposure levels
D) Assess lighting adequacy in a workstation
Answer: B
Explanation: The W‑1 is a basic screening tool used to identify jobs that may have ergonomic
hazards.
**Question 6.** Which factor is NOT part of the Revised NIOSH Lifting Equation?
A) Horizontal distance
B) Frequency of lifts per minute
C) Coupling quality
, AIEHS Certified Ergonomics Assessment
CEAP Exam
D) Ambient temperature
Answer: D
Explanation: Ambient temperature is not a variable in the NIOSH Lifting Equation; the equation
focuses on biomechanical factors.
**Question 7.** A worker who reports “tightness in the lower back after prolonged standing” is
most likely experiencing which MSD?
A) Lateral epicondylitis
B) Lumbar strain
C) De Quervain’s tenosynovitis
D) Carpal tunnel syndrome
Answer: B
Explanation: Prolonged standing can cause fatigue and strain in the lumbar region, leading to
lumbar strain.
**Question 8.** Which posture is considered neutral for the wrist during keyboard use?
A) 45° ulnar deviation
B) 30° extension
C) 0° deviation and 0° flexion/extension
D) 20° radial deviation
Answer: C
Explanation: A neutral wrist position has no deviation and minimal flexion/extension, reducing
stress on the carpal tunnel.
**Question 9.** Hand‑arm vibration exposure is most commonly associated with which type of
tool?
, AIEHS Certified Ergonomics Assessment
CEAP Exam
A) Air‑conditioner
B) Handheld power drill
C) Office printer
D) Standing desk
Answer: B
Explanation: Handheld power tools such as drills generate hand‑arm vibration that can lead to
HAVS (Hand‑Arm Vibration Syndrome).
**Question 10.** In the RULA scoring system, a score of 7 indicates:
A) No action required
B) Further investigation and possible change needed soon
C) Immediate ergonomic intervention required
D) Low risk, monitor only
Answer: C
Explanation: RULA scores of 7–8 denote a high risk level requiring prompt corrective action to
reduce musculoskeletal load.
**Question 11.** Which of the following is a secondary ergonomic risk factor?
A) Excessive force
B) Awkward posture
C) Contact stress
D) High repetition rate
Answer: C
Explanation: Contact stress (localized pressure on soft tissue) is considered a secondary risk
factor, whereas force, posture, and repetition are primary factors.
