NRCME - National Registry of Certified Medical Examiners Musculoskeletal System Assessment Questions and Answers

Question 1

A 45-year-old driver presents for a recertification exam. He has a below-the-knee amputation of his left leg and has been using a prosthesis for over 10 years with no issues. He operates a vehicle with an automatic transmission. He does not have an FMCSA-issued Skill Performance Evaluation (SPE) certificate. What is the most appropriate action for the medical examiner?

Accepted Answer

Disqualify the driver until he obtains a Skill Performance Evaluation (SPE) certificate.

Answer

According to 49 CFR 391.41(b)(1), the loss of a foot or leg is a disqualifying condition unless the driver has been granted a Skill Performance Evaluation (SPE) certificate. Even with a well-fitting prosthesis and a long, stable history, the SPE certificate is required for interstate CMV operation to formally document the driver's ability to safely operate the vehicle. The medical examiner cannot waive this requirement.

Question 2

When assessing a driver's hands and fingers, which two functions are critical for determining physical qualification under 49 CFR 391.41(b)(2)?

Accepted Answer

Prehension and power grasping.

Answer

The regulation at 49 CFR 391.41(b)(2)(i) specifically states that a person is physically qualified if they have no impairment of a hand or finger which interferes with 'prehension or power grasping'. These functions are essential for safely manipulating a steering wheel, shifting gears, and operating other vehicle controls. The other options describe movements, but are not the specific functional abilities cited in the regulation.

Question 3

A 58-year-old CMV driver reports a history of chronic low back pain following a lumbar fusion surgery performed three years ago. He is not taking any narcotic pain medication and reports his pain is well-controlled. On examination, he has a full range of motion of his extremities but has mildly limited lumbar flexion. What is the most important factor for the medical examiner to consider for certification?

Accepted Answer

Whether the condition is stable and does not interfere with safe driving functions.

Answer

The primary concern for any musculoskeletal condition, including post-surgical spinal issues, is whether it interferes with the ability to control and operate a CMV safely. The medical examiner must make a clinical judgment based on the stability of the condition, absence of incapacitating pain or weakness, and whether the driver can perform tasks like turning the head and body, shifting gears, and applying brakes. While the other factors are part of the overall assessment, the functional impact on safety is paramount.

Question 4

A driver with a fixed deficit of the right arm and hand due to a previous injury is seeking a Skill Performance Evaluation (SPE) certificate. As part of the application process, who must complete the medical evaluation summary?

Accepted Answer

A board-certified physiatrist or orthopedic surgeon.

Answer

The FMCSA requires that the medical evaluation summary, a key component of the SPE certificate application, must be completed by a specialist knowledgeable in the musculoskeletal system, specifically a board-qualified or board-certified physiatrist (doctor of physical medicine) or an orthopedic surgeon. This ensures an expert evaluation of the impairment and the individual's functional capabilities.

Question 5

Which of the following musculoskeletal conditions requires the most careful evaluation for potential sudden incapacitation while driving?

Accepted Answer

Rheumatoid arthritis with acute inflammatory flare-ups.

Answer

Rheumatoid arthritis is a systemic, inflammatory disease known for acute, episodic flare-ups that can cause severe pain, swelling, and loss of function in the joints, particularly the hands, wrists, and cervical spine. Such a flare-up could lead to sudden difficulty with steering, shifting, or turning the head, posing a significant risk of incapacitation. The other conditions are generally more stable and less likely to cause sudden, unpredictable functional loss.
