1. What Is asbestos?
   1. A group of naturally occurring fibrous silicate minerals.
   2. A fibrous substance used widely throughout the United States in the construction, shipbuilding, and automotive industries until the 1970s.
   3. A heat-stable substance commonly used in insulation, pipe coverings, boilers, brake pads, and many other products.
   4. All of the above.
2. Which asbestos exposure pathway most commonly leads to illness?
   1. Ingestion.
   2. Inhalation.
   3. Dermal contact.
   4. All are equally important.
3. Of the following, in the United States, the people in the general population most at risk of exposure to asbestos today is
   1. people who work in asbestos mining and milling.
   2. household contacts of workers engaged in the manufacture of asbestos-containing products.
   3. people working or living in homes and buildings with loose, crumbling, or disturbed asbestos materials.
   4. people who garden with vermiculite potting soil.
4. OSHA requires workers who are exposed to asbestos at levels higher than the PEL of 0.1 fibers/cc of air (8-hour TWA) to
   1. receive medical surveillance.
   2. be hospitalized immediately.
   3. file claims for work-related injuries.
   4. All of the above.
5. After inhalation, asbestos fibers
   1. are retained in the lungs, especially the lower lung fields.
   2. initiate responses that can lead to fibrosis of lung tissue.
   3. initiate responses that can lead to carcinogenesis.
   4. All of the above.
6. Of the four respiratory conditions associated with asbestos exposure, the condition that is not malignant but is associated with significant restrictive deficits is
   1. parenchymal asbestosis.
   2. asbestos-related pleural abnormalities.
   3. lung carcinoma.
   4. pleural mesothelioma.
7. Which condition is most likely to occur secondary to asbestos-associated pulmonary fibrosis?
   1. Peritoneal mesothelioma.
   2. Colon cancer.
   3. Cor Pulmonale.
   4. Constrictive pericarditis.
8. The most important risk factor for asbestos-associated diseases are
   1. genetic polymorphisms and exposure to air pollution.
   2. total exposure to asbestos and smoking.
   3. frequency of respiratory infections and coexistence of other fibrotic respiratory conditions.
   4. all are equally important.
9. A 64-year-old male who worked in shipyards in the United States in the 1960s and 1970s presents to his physician complaining of breathlessness, especially when he works or exercises. He says this symptom began several years ago but was so minor that he was not concerned. He also complains of a slight, nagging dry cough. Of the asbestos-associated diseases, the most likely culprit is
   1. parenchymal asbestosis.
   2. asbestos-related pleural abnormalities.
   3. lung carcinoma.
   4. pleural mesothelioma.
10. On auscultation of the patient described above, you are most likely to hear
    1. normal breath sounds.
    2. absent breath sounds.
    3. bibasilar end inspiratory rales.
    4. rhonchi.
11. As part of taking the exposure history, you should explore
    1. possible occupational exposures to asbestos.
    2. possible paraoccupational and secondary exposures to asbestos.
    3. use of personal protective equipment.
    4. All of the above.
12. Pulmonary function tests of a patient with parenchymal asbestosis are most likely to show
    1. normal results.
    2. low FVC.
    3. low FEV1.
    4. low FEV1/FVC.
13. On chest radiograph, small, irregular opacities in the bases of both lung fields is suggestive of
    1. parenchymal asbestosis.
    2. pleural plaques.
    3. benign asbestos pleural effusion.
    4. diffuse pleural thickening.
14. In caring for a patient who was exposed to asbestos, it is important to
    1. take steps to avoid further exposure to asbestos.
    2. counsel the patient to stop smoking.
    3. monitor the patient to facilitate early diagnosis.
    4. All of the above.
15. Patients diagnosed with an asbestos-associated disease should be instructed to
    1. continue working with asbestos as long as they use PPE.
    2. contact their doctor if they develop any sign of respiratory infection or other health change.
    3. receive influenza and pneumococcal vaccines only if they meet other criteria for being high risk.
    4. All of the above.
16. Asbestos fibers are released into the air mainly when
    1. asbestos-containing materials are loose, crumbling, or disturbed.
    2. asbestos is fixed in solid materials such as wallboard.
    3. asbestos-bearing rock lays unexposed deep underground.
    4. All of the above.
17. EPA's MCL for asbestos in drinking water is which of the following?
    1. 0.07 fibers per liter of drinking water.
    2. 7 million fibers per liter of drinking water.
    3. 700 fibers per liter of drinking water.
    4. 70,000 fibers per liter of drinking water.
18. Diffuse interstitial fibrosis resulting from inhalation of asbestos fibers and producing restrictive lung disease and progressive exertional dyspnea is termed
    1. lung carcinoma.
    2. pleural mesothelioma.
    3. parenchymal asbestosis.
    4. asbestos-related pleural abnormalities.
19. Asbestos-related pleural abnormalities include which of the following?
    1. Pleural plaques.
    2. Benign pleural effusions and diffuse pleural thickening.
    3. Rounded atelectasis.
    4. all of the above
20. The most typical abnormal finding on physical examination of a patient with significant asbestosis is
    1. a “doughy” feeling in the abdomen.
    2. bibasilar inspiratory rales on pulmonary auscultation.
    3. clubbing of the fingers.
    4. All of the above.
21. The two most important tests for diagnosing asbestos-associated diseases are
    1. BAL and lung biopsy.
    2. CT and HRCT scans.
    3. chest radiograph and pulmonary function tests.
    4. blood studies and colon cancer screening.
22. Managing parenchymal asbestosis involves
    1. smoking cessation.
    2. regular influenza and pneumococcal vaccines.
    3. respiratory therapies and pulmonary rehabilitation.
    4. All of the above.
23. Patients who were exposed to asbestos should
    1. stop smoking.
    2. avoid exposure to other respiratory irritants.
    3. avoid exposure to respiratory infections and contact their doctor if they get signs of infection or other health changes.
    4. all of the above
