What is the medical examiner certificate expiration date? Examination 11/16/2011; disqualified due to diagnosis of benign positional vertigo last episode 10/11/2011; return to medical examiner's office for complete new certification examination on 1/2/2012. Note asymptomatic since 10/11/2011 - driver qualified for two years. Expiration date 10/11/2013. Expiration date 1/2/2013. Do not certify - waiting period has not been completed. Expiration date 1/2/2014. - Expiration date 1/2/2014. Explanation: The certification date is always based on the date of the last complete examination. The waiting period for benign positional vertigo is two months symptom free. Additional tests above and beyond what are necessitated by the examination process should be performed only when ____________. The examination was unable to determine if the driver passed one or more requirements. The examination was unable to determine if the driver passed a majority of the requirements. The driver requests that additional tests be run. Requested by the driver's employer. - The examination was unable to determine if the driver passed one or more requirements. Explanation: Additional testing should only be performed if the results of standard testing and examination procedures do not provide a clear result as to whether or not the driver meets federal standards in one or more categories. The FMCSA directly regulates __________. Interstate commercial operations, including the driver. Intrastate operation, including the vehicle and motor carrier. Intrastate operation, including the transport of hazardous materials. Intrastate commercial operations, including the driver. - Interstate commercial operations, including the driver. Explanation: Many states use federal FMCSA standards to govern intrastate commercial operations, including the driver, but the FMCSA does not directly any intrastate functions. Driver Examination 2/17/2012, blood pressure 144/102. Driver given three-month certification to 5/17/12. The driver returns on 3/16/12 with blood pressure of 124/82. The next step for the medical examiner is? Perform a complete examination and certify the driver for one year if the driver passes the examination. Certify the driver for one year from 2/17/12. Require the driver to return for additional blood pressure checks since the blood pressure still does not meet certification requirements. Disqualify the driver. - Perform a complete examination and certify the driver for one year if the driver passes the examination. Explanation: The driver's blood pressure meets certification requirements. Given the previous elevated blood pressure, with respect to blood pressure guidelines the driver now qualifies for a one year certification. However, a complete examination is required each time a new certification interval has been designated, so a complete examination is now required and the date of expiration should be determined from the last date of full driver examination. The medical examiner's role in the exemption process includes _________. Issuing the exemption. Issuing the prescription for the driver's contact lenses and/or glasses. Providing the driver with contact information for the Federal Vision Exemption Program. Assuring that the driver has peripheral vision of at least 110 degrees in each eye. - Providing the driver with contact information for the Federal Vision Exemption Program. Explanation: The medical examiner's role in the exemption process is limited to performing the driver examination and providing the driver with contact information for the FMCSA related to the exemption process. A driver who wears contact lenses which correct farsightedness in one eye and nearsightedness in the other, but has no other visual impairments can be certified under what additional conditions? Only if the driver wears prescription glasses which provide the same correction as the contact lenses. FMCSA guidance indicates that a driver should not be certified under these circumstances. Only by federal exemption. The driver is always certifiable under these conditions. - FMCSA guidance indicates that a driver should not be certified under these circumstances. Explanation: FMCSA guidance indicates that contact lenses that correct one eye for distance and one eye for near vision are not acceptable.

May be certified if examined by an otolaryngologist who is familiar with the CMV driving duties who certifies the driver as medically qualified to drive a CMV. - May not be certified. Explanation: An average hearing loss of 41.7 decibels averaged across 500, 1000, and 2000 Hz in the better ear is disqualifying. The driver should be referred to obtain a hearing aid and may be certified if the driver passes while wearing a hearing aid. A specialist cannot determine certification, and a specialist cannot override medical qualification standards such as the minimum hearing requirement. Which of the following is acceptable for a driver who wears a hearing aid? Testing of the driver's hearing is waived if the driver presents a letter from a qualified specialist. Testing of the driver's hearing may be performed by the medical examiner using audiometric testing equipment. Testing of the driver's hearing may be performed by an audiologist or otolaryngologist using specialized audiometric testing equipment. Testing of the driver's hearing may be performed at 1,000 Hz only. - Testing of the driver's hearing is waived if the driver presents a letter from a qualified specialist. Explanation: Testing the hearing of a driver who wears a hearing aid may be accomplished in three ways: 1) whisper test, 2) audiometric testing by an otolaryngologist using specialized audiometric testing equipment, or 3) audiometric testing by an audiologist using specialized audiometric testing equipment. Audiometric testing is required to be conducted at 500 Hz, 1000 Hz, and 2000 Hz. On examination, a BP of 140/90 is obtained. A follow-up BP is 140/90. What certification options may be considered? The medical examiner should certify for two years if the driver is not taking anti-hypertensive medications. If the driver is taking antihypertensive medications, six months would be the maximum certification period. The medical examiner may obtain an additional reading or use his/her clinical judgment and consider BP and overall driver medical fitness for duty to determine certification status and certification period. The medical examiner may choose not to certify based on the BP readings. - The medical examiner may obtain an additional reading or use his/her clinical judgment and consider BP and overall driver medical fitness for duty to determine certification status and certification period. Explanation: The medical examiner may use clinical judgment to make an appropriate certification determination. Which of the following is true with regard to hypertension? The lower value of either systolic or diastolic blood pressure determines the stage of hypertension. Stage 1 hypertension is BP of 140-149/90-99. Stage 2 hypertension is BP of 170-179/100-109. Stage 3 hypertension is BP of greater than or equal to 180/110. - Stage 3 hypertension is BP of greater than or equal to 180/110. Explanation: The higher value of either systolic or diastolic blood pressure determines blood pressure stage. Stage 1 hypertension is SBP 140-159, DBP 90 - 99.

When the driver has a blood pressure of 182/84. - When the driver was diagnosed with Stage 1 hypertension on a previous examination and now has a blood pressure of 162/84. Explanation: A three-month certificate may be issued more than once in a driver's lifetime. A three-month certificate should not be issued consecutively. A driver with blood pressure of greater than or equal to 180/110 is not eligible for a three-month certificate. The maximum certification interval for a driver disqualified for Stage 3 hypertension, but whose blood pressure has declined to less than or equal to 140/90, is __________. Three months. Six months. One year. Two years. - Six months. Explanation: Once diagnosed with Stage 3 hypertension, a driver may be certified for six-month intervals.

Every two years beginning five years following coronary artery bypass grafting (CABG). - 3-6 months after percutaneous coronary intervention (PCI) and then every two years thereafter. Explanation: Exercise tolerance testing (ETT) is required every 2 years following MI and with angina. ETT is required annually beginning five years after CABG due to increased risk of graft closure. 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. - 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%. 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. - Certification depends on whether testing is conducted at altitudes above or below 5,000 feet.
