The parietal pleura
Covers the inner surface of the thoracic cavity
Immediately after the creation of an opening through the thorax into the pleural cavity,
Air would flow into the pleural cavity through the hole
A vessel that normally contains desaturated (venous) blood is
The peripheral chemoreceptors for respiratory control are
located in the carotid and aortic arteries
Given the following muscles, which are involved in active expiration?
internal intercostals, rectus abdominis
During inspiration, the intrapulmonary pressure must be
less than atmospheric pressure
Surfactant is a phospholipid that
reduces alveolar surface tension
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
is caused by an aerobic bacillus, is characterized by the formation of a granuloma
An example of ventilation without perfusion is
Which of the following manifestations is characteristic of emphysema
All of the following are part of the pathophysiology of chronic bronchitis except:
loss of lung elasticity
All of the following are part of the pathophysiology of asthma except
relaxation of bronchial smooth muscle
Which of the following conditions could cause absorption atelectasis?
Which of the following would indicate a right tension pneumothorax?
tracheal deviation to the left
All of the following are classes of drugs used to treat asthma except
Incomplete expansion of alveoli is called
In COPD, which of the following is true?
decrease in FEV 1.0
Air trapping in asthma is due to
increased expiratory flow resistance
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
In tuberculosis, the combination of the primary lesion and the lymph node granulomas is called the
All of the following are part of the pathophysiology of ARDS except:
decreased permeability of alveolar-capillary membrane
All of the following are ways that CO2 is carried in the blood except:
Which of the following conditions could impair the function of the mucociliary escalator system?
A, B, and C (smoking, dehydration, hypoxia)
The most common cause of pneumococcal pneumonia is
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:
The most common pulmonary infection in persons with AIDS is:
pneumocystis carinii pneumonia
Movement of air through an obstructed upper airway, particularly the vocal cords in the larynx, produces a crowing sound called
Sitting up with the mouth open and the chin thrust forward is a classic posture in a child with which condition?
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:
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
In children, the respiratory syncytial virus is a common cause of:
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

increase in partial pressure gradients of gases across the respiratory membrane
