Question 2
The following three questions pertain to Case 7.A: Asthma.
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..
Q3
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..
Q4
Question 4

Select one:
True
False
Feedback
The correct answer is: False.
Q5
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..
Q6
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)..
Q7
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.
