NRCME Medical Conditions and Guidelines 4 — Questions and Answers
Question 1: Under FMCSA regulations, which peripheral vision standard must a CMV driver meet?
- At least 50 degrees in the horizontal meridian in each eye
- At least 70 degrees in the horizontal meridian in each eye (Correct answer)
- At least 90 degrees in the horizontal meridian in each eye
- At least 120 degrees in the horizontal meridian in each eye
Correct answer: At least 70 degrees in the horizontal meridian in each eye
FMCSA requires a field of vision of at least 70 degrees in the horizontal meridian in each eye, making 70 degrees the correct answer.
Question 2: A driver on insulin for type 1 diabetes wishes to operate a commercial vehicle in interstate commerce. What program must they participate in?
- Diabetes Management Certification Program (DMCP)
- FMCSA Insulin-Treated Diabetes Mellitus (ITDM) Exemption Program (Correct answer)
- State-level diabetes waiver with annual physician sign-off
- No special program is required; insulin use is not restricted
Correct answer: FMCSA Insulin-Treated Diabetes Mellitus (ITDM) Exemption Program
Drivers using insulin for diabetes must obtain an exemption through the FMCSA ITDM Exemption Program to legally operate CMVs in interstate commerce.
Question 3: Which condition affecting the respiratory system would most likely result in disqualification of a CMV driver?
- Mild intermittent asthma controlled with an inhaler
- Moderate persistent asthma on inhaled corticosteroids
- Severe COPD causing significant dyspnea at rest (Correct answer)
- History of pneumonia fully resolved 6 months ago
Correct answer: Severe COPD causing significant dyspnea at rest
Respiratory dysfunction that interferes with the ability to control and drive a CMV safely, such as severe dyspnea at rest, is disqualifying.
Question 4: A driver has a blood pressure of 182/112 mmHg at examination. According to FMCSA hypertension guidelines, what is the correct action?
- Issue a 3-month certificate as with Stage 2 hypertension
- Certify for 1 year with monthly monitoring
- Disqualify; no certification until adequately treated and rechecked (Correct answer)
- Refer to cardiologist and certify pending clearance
Correct answer: Disqualify; no certification until adequately treated and rechecked
Stage 3 hypertension (≥180/110) is disqualifying; the driver must be treated and return for recheck before any certification can be issued.
Question 5: Which medication used to treat a psychiatric condition is most likely to be flagged as potentially disqualifying under FMCSA standards?
- Low-dose sertraline for mild depression with no side effects
- Benzodiazepine used daily for anxiety (Correct answer)
- Low-dose buspirone for generalized anxiety disorder
- Bupropion for major depression in full remission
Correct answer: Benzodiazepine used daily for anxiety
Daily benzodiazepine use is disqualifying under FMCSA regulations as it is a Schedule IV controlled substance with sedating properties.
Question 6: A CMV driver with a documented history of alcohol use disorder has been in sustained remission for 18 months. What is the appropriate certification action?
- Certify for 1 year with substance abuse professional (SAP) evaluation and follow-up (Correct answer)
- Disqualify permanently due to history of alcohol use disorder
- Certify for 2 years; 18 months remission exceeds the standard
- Certify only if the driver agrees to random alcohol testing
Correct answer: Certify for 1 year with substance abuse professional (SAP) evaluation and follow-up
Drivers with alcohol use disorder in remission may be certified following SAP evaluation and with appropriate follow-up monitoring.
Question 7: Which finding on a driver's abdominal examination would most warrant further workup before certifying a CMV driver?
- Mild epigastric tenderness without guarding
- Large pulsatile abdominal mass suggesting aortic aneurysm (Correct answer)
- Soft abdomen with mild obesity
- Healed laparotomy scar with no hernia
Correct answer: Large pulsatile abdominal mass suggesting aortic aneurysm
A large pulsatile abdominal mass is highly suspicious for an aortic aneurysm, which carries risk of rupture and sudden incapacitation, requiring further workup.
