UPDATE
1. A driver experienced a pneumothorax four weeks ago. The medical examiner tests
the driver's respiratory function and the forced vital capacity (FVC) is 58% of predicted.
What should the certification decision be?
•Do not certify pending additional testing.
•Certify for three months, pending driver follow up with personal physician and/or
specialist.
•Certify one year.
•Certify two years. - Answer- Do not certify pending additional testing.
Explanation: The driver may not be certified until FVC is > 60% predicted or additional
testing reveals acceptable respiratory parameters - e.g., pulse oximetry with O2 > 92%.
2. Pulse oximetry O2 saturation = 90%. Arterial blood gas (ABG): PaO2 = 60 mm Hg,
PaCO2 = 42 mm Hg. What is the certification determination?
•Do not certify.
•Certify three months pending additional testing.
•Certify for one year.
•Certification depends on whether testing is conducted at altitudes above or below
5,000 feet. - Answer- Certification depends on whether testing is conducted at altitudes
above or below 5,000 feet.
,The certification determination related to arterial blood gas (ABG) testing depends on
the altitude at which testing is performed. A PaO2 of less than 65 mm Hg is
disqualifying at altitudes of less than 5,000 feet; a PaO2 of less than 60 mm Hg is
disqualifying at altitudes of greater than 5,000 feet.
3. The maximum certification interval for a driver diagnosed with asthma is __________.
•Three months.
•Six months.
•One year.
•Two years. - Answer- Two years.
The maximum certification interval for asthma is two years.
4. Spirometry testing should be performed on drivers who smoke and who are over
__________ years of age.
•30
•35
•40
•45 - Answer- 35
5. Which of the following is disqualifying?
•PaCO2 less than 45 mm Hg.
•PaO2 less than 70 mm Hg at altitudes less than 5000 feet.
•PaO2 less than 65 mm Hg at altitudes above 5000 feet.
•PaCO2 greater than 45 mm Hg. - Answer- PaCO2 greater than 45 mm Hg.
PaCO2 of less than 45 mm Hg is not disqualifying, but PaCO2 of greater than 45 mm
Hg is disqualifying. An O2 saturation of less than 65 mm Hg is disqualifying at altitudes
below 5,000 feet and an O2 saturation of less than 60 mm Hg is disqualifying at
altitudes above 5,000 feet.
, 1. A driver with a history of bacterial meningitis with early seizures or a single
unprovoked seizure requires a waiting period of __________ seizure free and off
anticonvulsant medications.
•One year.
•Two years.
•Five years.
•Ten years. - Answer- Five years.
Explanation: The waiting period for a history of bacterial meningitis with early seizures
or single unprovoked seizure is five years seizure free and off anticonvulsant
medications.
2. Transient ischemic attacks (TIA's) are automatically disqualifying for __________.
After the minimum waiting period the certification depends on the interval history,
general health, neurological examination, and compliance with the treatment program.
•Three months.
•Six months.
•Nine months.
•One year. - Answer- One year.
Explanation: The minimum waiting period for transient ischemic attacks (TIA's) is one
year.
3. A driver with peripheral neuropathy __________.
•May be certified for one year.
•Should not be certified by regulation.
•Should not be certified by guidance.
•May be certified for three months pending specialist evaluation. - Answer- Should not
be certified by guidance.
Explanation: Peripheral neuropathy is a disqualifying condition. However, this is a
guidance recommendation, not a regulatory requirement, so Medical Examiners may
consider qualification for a driver with peripheral neuropathy.
