Which of the following statements about asthma is NOT CORRECT? Select one: a. Asthma is primarily a restrictive respiratory disorder. b. Increased airway resistance is characteristic of asthma. c. In asthma, the FEV1/FVC ratio may be decreased from normal. d. Asthma may be characterized by a hyperinflation of the lungs, which is reflected as an increase in residual volume. e. Asthma may be associated with symptoms such as coughing, wheezing, shortness of breath, or chest tightness. Feedback The correct answer is: Asthma is primarily a restrictive respiratory disorder.. Q 3 Question 3 Which of the following statements about asthma is CORRECT? Select one: a. Increased airway resistance would result from an increase in airway radius. b. A beta-agonist would promote bronchoconstriction thus would reduce airway resistance. c. V/Q mismatching in asthma would generally be characterized as an increase in the shunt fraction. d. Anti-inflammatory agents like a glucocorticoid would not be beneficial to a patient with asthma, since asthma is a disorder that is not associated with inflammation. Feedback The correct answer is: V/Q mismatching in asthma would generally be characterized as an increase in the shunt fraction.. Q 4 Question 4 Hypocapnia occurs as a consequence of hypoventilation, which reduces CO2 levels. Select one: True False Feedback The correct answer is: False. Q 5 Question 5 The following three questions pertain to Case 7.B: Pulmonary Fibrosis. Which of the following statements about Pulmonary Fibrosis is CORRECT? Select one: a. Pulmonary fibrosis is an obstructive pulmonary disorder. b. Pulmonary fibrosis is characterized by reduced or restricted airflow through the airways. c. The parameter of Fick’s law of diffusion altered in a person with pulmonary fibrosis is “x” or the distance across which the gas must travel for exchange to occur. d. Persons with pulmonary fibrosis have an increased compliance. Feedback The correct answer is: The parameter of Fick’s law of diffusion altered in a person with pulmonary fibrosis is “x” or the distance across which the gas must travel for exchange to occur.. Q 6 Question 6 Which of the following statements about Pulmonary Fibrosis is NOT CORRECT? Select one: a. Persons with pulmonary fibrosis have an increased total lung capacity (TLC). b. Pulmonary fibrosis may be associated with an inflammatory process that leads to an increase in scar tissue. c. Reduced PaO2 levels are due to impaired gas exchange. d. Decreased PaCO2 levels may be a consequence of hyperventilation. Feedback The correct answer is: Persons with pulmonary fibrosis have an increased total lung capacity (TLC).. Q 7 Question 7 When a person with pulmonary fibrosis exercises, the ability to equilibrate oxygen may be compromised by an increased thickness of the respiratory membrane. Select one: True False Feedback The correct answer is: True. Q 8 Question 8 The following three questions pertain to Case 7.C: COPD. Our patient with COPD has a “prolonged expiratory phase” to his respirations. In the case of emphysema what is the most likely mechanism that underlies this slowing of forced expiration? Select one: a. Increased airway resistance due to mucous b. Loss of elastic recoil of the lungs c. Increased airway resistance due to inflammation d. Smooth muscle constriction of the airways Feedback The correct answer is: Loss of elastic recoil of the lungs. Q 9 Question 9 Our patient with COPD has an increased PaCO2 value at 69 mmHg and an increased bicarbonate value at 34 mEq/L. Based upon these values our patient most likely was in Select one: a. Respiratory acidosis with renal compensation b. Respiratory alkalosis with renal compensation c. Metabolic acidosis with respiratory compensation d. Metabolic alkalosis with respiratory compensation Feedback The correct answer is: Respiratory acidosis with renal compensation. Q 10 Question 10 The primary risk factor for COPD is tobacco smoking, but an inherited genetic condition is responsible for a minority of the cases. Select one: True False Feedback The correct answer is: True. Q 11 Question 11 The following three questions pertain to Case 7.D: Pulmonary Embolism. Which of the following are NOT considered a specific risk factor or indication for pulmonary embolism? Select one: a. Female b. Birth control pill use c. Overweight d. Deep vein thrombosis (DVT) Feedback The correct answer is: Female. Q 12 Question 12 Virchow’s triad includes all of the following EXCEPT: Select one: a. Change in vessel wall b. Decreased blood flow c. Decreased coagulability of blood d. Increased coagulability of blood Feedback The correct answer is: Decreased coagulability of blood. Q 13 Question 13 One of the most common sources of embolism in pulmonary embolism is deep vein thrombosis of the popliteal vein. Select one: True False Feedback The correct answer is: True. Q 14 Question 14 Jason smoked a considerable amount in college. One day, he experienced sharp chest pain and could not catch his breath. His roommate took him to the emergency room, where he was diagnosed with a collapse lung. Based upon the above information, Jason’s condition would most likely be described as a
