  • 4. 
    During a cardiac arrest, a 58-year-old man, a non-smoker, receives cardiopulmonary resuscitative measures and is brought to the hospital, where he is intubated. During the intubation procedure he suffers aspiration of gastric contents (pasta with mushrooms and peas). Over the next 10 days he develops a non-productive cough along with a fever to 37.9 C. A chest radiograph reveals a 4 cm diameter mass with an air-fluid level in the right lung. A sputum gram stain reveals mixed flora. Which of the following conditions is he most likely to have?
    • A. 

      Squamous cell carcinoma

    • B. 

      Lung abscess

    • C. 

      Chronic bronchitis

      Bronchiectasis

  • 5. 
    Alphla 1 antitrypsin deficiency leads to emphysema because:
    • A. 

      Lt leads to deficient formation of pulmonary elastic tissue 

    • B. 

      It leads to excessive destruction of elastic tissue by elastase enzymes 

    • C. 

      Lt predisposes to Bronchial inflammation and obstruction. 

    • D. 

      All of the above

    • E. 

      Non of the above 

  • 6. 
    All of the following conditions can cause atelectasis or collapse except:
    • A. 

      Compression of bronchi by enlarged lymph nodes. 

    • B. 

      Alphla 1 antitrypsin deficiency

    • C. 

      Pneumothorax

    • D. 

      Bronchial tumors

  • 7. 
    A 55-year-old woman has had fever and dyspnea for a month along with a 2 kg weight loss. On physical examination her temperature is 37.7 C. A chest radiograph shows a reticulonodular pattern along with prominent hilar lymphadenopathy. A transbronchial lung biopsy is performed, and microscopic examination shows no viral inclusions, no fungi, no acid fast bacilli, and no atypical cells. Which of the following diseases is she most likely to have?
    • A. 

      Silicosis

    • B. 

      Sarcoidosis 

    • C. 

      TB

    • D. 

      Usual interstitial pneumonia

    • E. 

      Asbestosis 

  • 8. 
    A 55-year-old man has been a cigarette smoker for the past 39 years. He has noted some blood-streaked sputum on coughing during the past week. He also has back pain. A chest radiograph shows a small 3 cm right hilar mass with several 1 to 2 cm peripheral lung nodules. A bone scan reveals multiple areas of increased uptake in the vertebrae, ribs, and pelvis. A sputum cytology reveals the presence of clusters of small cells having hyperchromatic nuclei and almost no cytoplasm. Which of the following laboratory test findings is he most likely to have as a consequence of his lung disease?
    • A. 

      Positive antinuclear antibody

    • B. 

      Platelet count of 55,000/microliter

    • C. 

      Plasma cortisol at 8 am of 5 microgm/dL (N= 10-20 micrigram/dL) 

    • D. 

      Serum sodium of 113 mmol/L

    • E. 

      Hyperuricemia

  • 9. 
    A 40-year-old woman has had a high fever for a week, accompanied by a cough productive of yellowish sputum. On physical examination her temperature is 38.2 C. There are diffuse rales in all lung fields. Her chest radiograph reveals patchy infiltrates in all lung fields, and there is a 4 cm rounded area of consolidation in the left upper lobe that has an air-fluid level. Examination of her sputum reveals numerous neutrophils. Which of the following infectious agents is most likely causing her pulmonary disease?
    • A. 

      Staphylococcus aureus

    • B. 

      Aspergillus niger

    • C. 

      Mycoplasma pneumoniae

    • D. 

      Adenovirus

    • E. 

      Mycobacterium tuberculosis

  • 10. 
    A 36-year-old woman has had increasing dyspnea for 8 years. She has no cough or increased sputum production. On physical examination there is hyperresonance to percussion. A chest radiograph reveals increased lung volumes with flattening of the diaphragmatic leaves bilaterally. The right heart border is prominent. A chest CT scan demonstrates decreased attenuation (broncho vascular marking) in all lung fields. Which of the following laboratory findings is she most likely to have?
    • A. 

      Decreased serum ceruloplasmin

    • B. 

      Increased sweat chloride

    • C. 

      Elevated blood ethanol

    • D. 

      Decreased serum alpha-1-antitrypsin

    • E. 

      Positive antinuclear antibody test

  • 11. 
    A 12-year-old girl has the acute onset of dyspnea and wheezing. She coughs up a large, thick mucus plug. She has experienced similar previous episodes for the past 7 years, all of which lasted 1 to 6 hours. On physical examination her vital signs include T 37.1 C, P 109/minute, RR 27/minute, and BP 90/60 mm Hg. There are decreased breath sounds in all lung fields. A chest radiograph reveals hyperinflation but no infiltrates. Laboratory studies show WBC count of 8300/microliter with differential count of 60 segs, 3 bands, 16 lymphs, 10 monos, and 11 eosinophils. A sputum sample examined microscopically has increased numbers of eosinophils. Which of the following is the most likely diagnosis?
    • A. 

      Hypersensitivity pneumonitis

    • B. 

      Mycoplasma pneumonia infection

    • C.
