5 Matching Questions

  1. emphysema
  2. hypercapnia
  3. pulmonary fibrosis
  4. cyanosis
  5. atelectasis
  1. a excessive fibrous or connective tissue i lung
  2. b increased amount of CO2 in the blood: depression of respiratory center by drugs; diseases of the medulla;
  3. c lung tissue collapses due to external pressure or due to removal of air due to absorption or hypoventilation
  4. d bluish discoloration of skin and mucous membranes; reduced hemoglobin in blood
  5. e permanent enlargement of gas exchange airways with destruction of alveolar walls

5 Multiple Choice Questions

  1. gas or air enterspleural space separating lung from rib cage and destroying the negative pressure gradient
  2. tidal volume gradually increases followed by gradual decrease and a period of apnea before returning to a normal respiratory pattern; from conditions that slow blood flow to the brainstem
  3. presence of fluid in the pleural space; results from fluid coming through capillaries
  4. usually viral laryngealtracheobronchitis, edema and mucous cause airway to narrow, barking cough
  5. autosomal recessive inherited disease on chromosome 7; causes abnormal expression of a protein affecting airway, bile duts, pancreas, sweat ducts and vas deferens

5 True/False Questions

  1. pulmonary edemaexcess water in the lung, HD, diminishes gas exchange


  2. hyperventilationinadequate alveolar ventilation inelation to metabolic demands; CO2 removal does not keep up with production and level increases in arterial blood causing hypercapnia


  3. hypoventilationalveolar ventilation exceeding metabolic demands; lungs remove CO2 faster than it is produced by cellular metabolism


  4. resting ventilatory rateinadequate gas exchange where either oxygen is too low or carbon dioxide is too high


  5. flail chestfractures causing instability of chest wall, paradoxic movent, impairs gas exchange
