NRCME Medical Conditions and Guidelines 3 — Questions and Answers
Question 1: A driver on metformin for type 2 diabetes has an HbA1c of 8.2% with no hypoglycemic episodes in the past year. What is the correct certification decision?
- Certify for 1 year; metformin does not cause hypoglycemia (Correct answer)
- Disqualify due to HbA1c above 8%
- Require insulin exemption regardless of medication type
- Certify for 2 years as long as there are no complications
Correct answer: Certify for 1 year; metformin does not cause hypoglycemia
Metformin alone does not cause hypoglycemia, so a driver on metformin may be certified for 1 year without the insulin exemption program.
Question 2: Under FMCSA hearing standards, a driver must perceive a forced whispered voice at what minimum distance in the better ear?
- 3 feet without hearing aids
- 5 feet with or without hearing aids (Correct answer)
- 10 feet without hearing aids
- 5 feet without hearing aids
Correct answer: 5 feet with or without hearing aids
FMCSA requires the ability to perceive a forced whispered voice in the better ear at not less than 5 feet, with or without a hearing aid.
Question 3: Which finding in a driver's cardiovascular history would allow certification after specialist evaluation under FMCSA guidelines?
- Current unstable angina
- Myocardial infarction 6 months ago with full recovery and normal stress test (Correct answer)
- Symptomatic congestive heart failure with ejection fraction of 30%
- Current third-degree heart block without pacemaker
Correct answer: Myocardial infarction 6 months ago with full recovery and normal stress test
A driver may be certified after MI recovery if a cardiologist confirms adequate functional capacity and no significant residual risk.
Question 4: A driver with obstructive sleep apnea is compliant with CPAP therapy (AHI < 5 on therapy) and denies daytime sleepiness. What is the appropriate certification period?
- 6 months to verify continued compliance
- 1 year with documentation of CPAP compliance (Correct answer)
- 2 years if asymptomatic
- Disqualify; sleep apnea is permanently disqualifying
Correct answer: 1 year with documentation of CPAP compliance
CPAP-compliant drivers with OSA can be certified for 1 year with documentation of ongoing therapy effectiveness.
Question 5: Which musculoskeletal condition would most likely require a skills performance evaluation (SPE) certificate for continued CMV operation?
- Lumbar disc herniation with resolved radiculopathy
- Below-knee amputation with functional prosthesis (Correct answer)
- Mild osteoarthritis of the knee
- Cervical strain with full range of motion recovered
Correct answer: Below-knee amputation with functional prosthesis
Loss of a limb or limb dysfunction that affects control of the vehicle requires a Skills Performance Evaluation (SPE) certificate.
Question 6: A commercial driver taking a Schedule II controlled substance for chronic pain is applying for certification. What is the examiner's appropriate action?
- Certify if the driver's physician states the medication is necessary
- Certify for 6 months with quarterly drug screening
- Disqualify; Schedule II substances are prohibited for CMV drivers (Correct answer)
- Require a specialist evaluation before certifying
Correct answer: Disqualify; Schedule II substances are prohibited for CMV drivers
FMCSA regulations prohibit CMV operation while using Schedule I or II controlled substances, regardless of prescription status.
Question 7: A driver presents with a history of TIA (transient ischemic attack) 4 months ago with complete resolution. What is the FMCSA standard for certification?
- Certify immediately if neurological exam is normal
- Wait 1 year from the TIA before certifying with specialist clearance (Correct answer)
- Disqualify permanently after any TIA
- Certify after 6 months if imaging is normal
Correct answer: Wait 1 year from the TIA before certifying with specialist clearance
FMCSA advisory criteria recommend waiting at least 1 year after a TIA and obtaining neurological specialist clearance before certification.
