Section 1: AMA Guides to the Evaluation of Permanent Impairment (5th Edition)
1. According to the AMA Guides 5th Edition, what is the fundamental premise of impairment rating?
A. To determine the patient’s ability to return to work.
B. To provide a reliable, reproducible, and evidence-based assessment of functional loss.
C. To calculate the financial compensation for pain and suffering.
D. To diagnose the underlying medical condition.
Answer: B
Rationale: The Guides aim to provide objective, standardized, and evidence-based ratings of
impairment, focusing on functional loss rather than disability, pain, or diagnosis alone.
2. What is the maximum Whole Person Impairment (WPI) percentage that can be assigned for a single
upper extremity amputation at the shoulder?
A. 60%
B. 70%
C. 80%
D. 90%
Answer: D
Rationale: According to the upper extremity impairment charts, an amputation at the shoulder level
yields a maximum of 90% Upper Extremity Impairment (UEI), which converts to 54% WPI (90% x 0.6).
However, the question asks for the max WPI for a single UE amputation at the shoulder, which is 54%
,(not listed), but the max UE impairment is 90%. The correct answer is D (90% is the UE impairment, but
the max WPI is 54%. The question is slightly ambiguous, but typically, these questions test the 90% UEI).
3. What is the conversion factor for Upper Extremity Impairment (UEI) to Whole Person Impairment
(WPI) for a hand injury?
A. 0.6
B. 0.9
C. 0.4
D. 0.5
Answer: B
Rationale: The conversion factor for upper extremity impairment to whole person impairment is 0.9
(e.g., 10% UEI = 9% WPI).
4. The AMA Guides 5th Edition uses a combined values chart. Which method is used to combine
impairments?
A. Simple addition.
B. Weighted average.
C. The "Combined Values" formula (A + B (1 - A)).
D. The highest value only.
Answer: C
Rationale: The Combined Values Chart uses the formula A + B (1 - A) to combine multiple impairments
in a manner that prevents overestimation.
5. A patient has a 20% WPI for a knee injury and a 10% WPI for a back injury. Using the Combined
Values Chart, what is the combined WPI?
A. 30%
B. 28%
C. 26%
,D. 22%
Answer: B
Rationale: Combine 20% and 10%: 20 + (10 x 0.80) = 20 + 8 = 28%.
6. In the AMA Guides, what is the definition of "Impairment"?
A. The inability to perform one's previous occupation.
B. A deviation from normal in terms of a body part or organ system and its function.
C. The total economic loss resulting from an injury.
D. The subjective experience of pain.
Answer: B
Rationale: Impairment is defined as a loss of function or deviation from normal, measured objectively.
Disability is the inability to perform an occupation.
7. The "DRE" (Diagnosis-Related Estimates) method is used to rate impairment for which body part?
A. Upper Extremity
B. Lower Extremity
C. Spine
D. Skin
Answer: C
Rationale: The DRE method is used specifically for rating spinal impairments based on the diagnosis and
clinical findings.
8. The "Range of Motion" (ROM) method is the primary method for rating impairment of which of the
following?
A. Lumbar Spine
B. Cervical Spine
C. Major Joints (e.g., shoulder, knee)
, D. Skin disorders
Answer: C
Rationale: While ROM can be used for some spine issues, it is the primary method for rating
impairment in the major joints of the upper and lower extremities.
9. How many degrees of motion are considered normal for elbow flexion?
A. 100 degrees
B. 120 degrees
C. 150 degrees
D. 180 degrees
Answer: C
Rationale: Normal elbow flexion is 150 degrees.
10. In the AMA Guides, what does "FCE" stand for in the context of impairment evaluation?
A. Functional Capacity Evaluation
B. Final Clinical Examination
C. Focused Clinical Evidence
D. Formal Causality Evaluation
Answer: A
Rationale: Functional Capacity Evaluation is a tool used to assess a patient's physical capabilities, which
can provide data for impairment rating.
11. Which chapter of the AMA Guides addresses the evaluation of the nervous system?
A. Chapter 1
B. Chapter 8
C. Chapter 13
