5 >>A 48-year-old Haitian man presents with shortness of breath. Chest x-ray reveals a right pleural effusion extending about halfway up the chest. The patient has no other known medical problems and is on no medicines. The rest of the general physical examination is unremarkable. Diagnostic thoracentesis reveals the following: lactate dehydrogenase (LDH) 1.7 ?kat/L (100 U/L), glucose 6.4 mmol/L (150 mg/dL), and amylase 1.6 ?kat/L (90 U/L). Cell count reveals 1000 red cells per microliter and 1000 white cells per microliter (differential: 50% neutrophils, 25% lymphocytes, and 25% monocytes).

  • (B) alveolar proteinosis
  • (C) polymyositis
  • (D) chronic eosinophilic pneumonia

9 >>One week after a right total hip replacement a 65- year-old woman develops the sudden onset of shortness of breath. A workup reveals normotension, a prominent second heart sound, hypoxemia, sinus tachycardia with new right axis deviation on the electrocardiogram, and a normal chest x-ray. Oxygen is administered. Impedance plethysmography is consistent with a large proximal clot in the left leg. Which of the following would be the most reasonable next step? ?

Download
  • (A) Performance of a pulmonary angiogram
  • (B) Performance of perfusion scintigraphy
  • (C) Administration of tissue plasminogen activator
  • (D) Dextrocardia

10 >>Expected results of the pulmonary function testing of the man described above would include ?

  • (A) increased lung elastic recoil
  • (B) increased total lung capacity
  • (C) reduced functional residual capacity
  • (D) increased vital capacity

11 >>Which of the following would be the most reasonable next step in the assessment of the patient described above? ?

  • (A) Acid starch gel
  • (B) Measurement of sweat chloride concentration
  • (C) High-resolution CT scan
  • (D) Exercise stress test

12 >>Which of the following statements concerning the pathogenesis of ?1-antitrypsin deficiency is true? ?

  • (A) Emphysema results from an inability to inhibit alveolar destruction by neutrophils.
  • (B) Clinical deficiency of ?1 -antitrypsin usually results 1 from one of several nonsense mutations that cause a truncated protein product.
  • (C) The disease is inherited in a dominant fashion
  • (D) Emphysema results from an inability to inhibit alveolar destruction by neutrophils

13 >>To decrease the likelihood of drug toxicity, the theophylline dose should be reduced in a patient with asthma in which of the following circumstances? ?

  • (A) Active tobacco user
  • (B) Azithromycin use for Mycoplasma pneumonia
  • (C) Augmented use for recurrent otitis media

The carbon monoxide diffusion capacity is reduced to 35% of normal. Resting arterial hypoxemia is demonstrated on arterial blood-gas testing. Transbronchial biopsy results reveal an increase in inflammatory cells on the alveolar surface, predominantly macrophages, as well as diffuse intraalveolar fibrosis.

  • (A) oral prednisone
  • (B) oral cyclophosphamide
