NRCME Hypertension Guidelines 2 — Questions and Answers
Question 1: Under FMCSA regulations, a commercial driver with a blood pressure reading of 160/100 mmHg at the time of examination should be:
- Certified for 1 year with follow-up required (Correct answer)
- Disqualified permanently
- Certified for 3 years with no restrictions
- Certified for 2 years with no follow-up
Correct answer: Certified for 1 year with follow-up required
Stage 2 hypertension (160-179/100-109 mmHg) permits a one-time certification of up to 12 months, requiring treatment and follow-up to confirm BP control.
Question 2: A CME is examining a driver taking a thiazide diuretic for hypertension. Which side effect is most relevant to commercial driving safety?
- Hypokalemia causing muscle weakness or cramps (Correct answer)
- Increased appetite
- Hair thinning
- Elevated cholesterol
Correct answer: Hypokalemia causing muscle weakness or cramps
Thiazide diuretics can cause hypokalemia leading to muscle weakness, cramps, and fatigue, all of which can impair a driver's ability to safely operate a commercial vehicle.
Question 3: Which blood pressure threshold constitutes Stage 3 (severe) hypertension requiring disqualification under FMCSA guidelines?
- ≥180 systolic or ≥110 diastolic (Correct answer)
- ≥160 systolic or ≥100 diastolic
- ≥140 systolic or ≥90 diastolic
- ≥150 systolic or ≥95 diastolic
Correct answer: ≥180 systolic or ≥110 diastolic
Blood pressure of 180/110 mmHg or higher is Stage 3 hypertension and disqualifies a driver from certification until it is treated and confirmed below that threshold.
Question 4: A driver on beta-blocker therapy reports dizziness when standing quickly. This symptom most likely represents:
- Orthostatic hypotension (Correct answer)
- Hypertensive crisis
- Benign positional vertigo
- Cerebellar dysfunction
Correct answer: Orthostatic hypotension
Beta-blockers can reduce cardiac output and blunt compensatory reflexes, causing orthostatic hypotension with positional dizziness that may impair driving.
Question 5: When a driver's BP is confirmed at 179/109 mmHg after two separate readings, the FMCSA guidance recommends:
- One-time certificate up to 12 months with treatment initiated (Correct answer)
- Permanent disqualification
- Full 24-month certification
- Deferral with no path to certification
Correct answer: One-time certificate up to 12 months with treatment initiated
Stage 2 hypertension (160-179/100-109) allows a single 12-month certificate to allow time for treatment and BP reduction before re-evaluation.
Question 6: Which antihypertensive drug class is most associated with a chronic dry cough that could distract a commercial driver?
- ACE inhibitors (Correct answer)
- Calcium channel blockers
- Beta-blockers
- Alpha-1 blockers
Correct answer: ACE inhibitors
ACE inhibitors cause a bradykinin-mediated dry cough in up to 20% of patients, which can be distracting and disruptive during driving.
Question 7: A CME documents a driver's BP as 138/88 mmHg on exam. Per FMCSA classification, this driver falls into which category?
- Stage 1 hypertension — certify up to 1 year
- Normal — certify up to 2 years (Correct answer)
- Stage 2 hypertension — certify up to 1 year
- Stage 3 — disqualify
Correct answer: Normal — certify up to 2 years
A BP below 140/90 mmHg is considered normal (or treated-controlled) under FMCSA guidelines, qualifying the driver for a standard 2-year medical certificate.
