  1. The parietal pleura
    Covers the inner surface of the thoracic cavity
  2. Immediately after the creation of an opening through the thorax into the pleural cavity,
    Air would flow into the pleural cavity through the hole
  3. A vessel that normally contains desaturated (venous) blood is
    Pulmonary artery
  4. The peripheral chemoreceptors for respiratory control are
    located in the carotid and aortic arteries
  5. Given the following muscles, which are involved in active expiration?
    internal intercostals, rectus abdominis
  6. During inspiration, the intrapulmonary pressure must be
    less than atmospheric pressure
  7. Surfactant is a phospholipid that
    reduces alveolar surface tension
  8. Which of the following statements about the oxyhemoglobin dissociation curve is true?
    the curve shifts to the right when there is a decrease in pH
  9. Tuberculosis
    is caused by an aerobic bacillus, is characterized by the formation of a granuloma
  10. An example of ventilation without perfusion is
    pulmonary embolus
  11. Which of the following manifestations is characteristic of emphysema
    weight loss
  12. All of the following are part of the pathophysiology of chronic bronchitis except:
    loss of lung elasticity
  13. All of the following are part of the pathophysiology of asthma except
    relaxation of bronchial smooth muscle
  14. Which of the following conditions could cause absorption atelectasis?
    chronic bronchitis
  15. Which of the following would indicate a right tension pneumothorax?
    tracheal deviation to the left
  16. All of the following are classes of drugs used to treat asthma except
    beta blockers
  17. Incomplete expansion of alveoli is called
    Atelectasis
  18. In COPD, which of the following is true?
    decrease in FEV 1.0
  19. Air trapping in asthma is due to
    increased expiratory flow resistance
  20. Oxygen diffusion from the capillary blood to the tissue cell occurs because
    The PO2 is higher in the capillary blood than in the tissue cell
  21. In tuberculosis, the combination of the primary lesion and the lymph node granulomas is called the
    Ghon's complex
  22. All of the following are part of the pathophysiology of ARDS except:
    decreased permeability of alveolar-capillary membrane
  23. All of the following are ways that CO2 is carried in the blood except:
    oxyhemoglobin
  24. Which of the following conditions could impair the function of the mucociliary escalator system?
    A, B, and C (smoking, dehydration, hypoxia)
  25. The most common cause of pneumococcal pneumonia is
    Streptococcus pneumonia
  26. During one of the pathologic stages of bacterial pneumonia, the alveolar spaces are engorged with fluid and hemorrhagic exudate. This stage is referred to as:
    Hyperemia
  27. The most common pulmonary infection in persons with AIDS is:
    pneumocystis carinii pneumonia
  28. Movement of air through an obstructed upper airway, particularly the vocal cords in the larynx, produces a crowing sound called
    Stridor
  29. Sitting up with the mouth open and the chin thrust forward is a classic posture in a child with which condition?
    Epiglottitis
  30. A patient expires normally; then, using forced expiration, he blows as much air as possible into a spirometer. The amount of air remaining in the lungs is called:
    Residual volume
  31. Administering high concentrations of oxygen to a person with chronic hypoxia can be harmful because:
    the oxygen chemoreceptors which are the main stimulus for ventilation are suppressed
  32. In children, the respiratory syncytial virus is a common cause of:
    bronchiolitis
  33. In the person with COPD, pursed-lip breathing improves ventilation because it:
    increases small airway pressures during expiration as a means of preventing their collapse
  34. Which of the following would increase the rate of gas exchange across the respiratory membrane?
    increase in partial pressure gradients of gases across the respiratory membrane
  35. The pneumotaxic center
    inhibits the apneustic center
  36. Which of the following criteria are used to diagnose cystic fibrosis?
    A, B, and C (deficient pancreatic enzymes in GI secretions, increased sodium and chloride in sweat, chronic pulmonary infections)
  37. The oldest and most widespread of the industrial diseases (pneumoconioses) is
    Silicosis
  38. The disorder that is characterized by angulation of the spine both posteriorly and laterally is called:
    Kyphoscoliosis
  39. Pleural effusion that results from infection and contains pus is called
    Empyema
  40. A condition that causes instability of the chest wall characterized by pendulum movement of the mediastinal contents during the breathing cycle is known as:
    Flail Chest injury
