Question 1
Which of the following is an irreversible condition that results in progressive obstruction of
airflow and includes chronic bronchitis and emphysema?
A) Asthma
B) Bronchiectasis
C) Chronic Obstructive Pulmonary Disease (COPD)
D) Pulmonary Fibrosis
E) Acute Bronchitis
Correct Answer: C) COPD (chronic obstructive pulmonary disease)
Rationale: COPD is defined as an irreversible condition resulting in progressive
airflow obstruction, encompassing chronic bronchitis and emphysema.
Question 2
What condition is characterized by a partially reversible airflow limitation as well as the
presence of a chronic productive cough?
A) Emphysema
B) Asthma
C) Bronchiectasis
D) Chronic obstructive bronchitis
E) Cystic Fibrosis
Correct Answer: D) Chronic obstructive bronchitis
Rationale: Chronic obstructive bronchitis is specifically described as having partially
reversible airflow limitation and a chronic productive cough.
,Question 3
Which condition involves the permanent enlargement of the air spaces distal to the terminal
bronchioles?
A) Chronic Bronchitis
B) Asthma
C) Emphysema
D) Bronchiectasis
E) Acute Respiratory Distress Syndrome (ARDS)
Correct Answer: C) Emphysema
Rationale: Emphysema is characterized by the permanent enlargement of air spaces
distal to the terminal bronchioles.
Question 4
Normal physiologic aging leads to what approximate decrease in Forced Expiratory Volume in 1
second (FEV1) per year?
A) 10 cc/year
B) 20 cc/year
C) 30 cc/year
D) 40 cc/year
E) 50 cc/year
Correct Answer: C) 30cc/year
Rationale: Normal physiologic aging typically results in a 30 cc/year decrease in
FEV1.
,Question 5
What spirometry measurement is defined as the average flow rate during the first second of a
Forced Vital Capacity (FVC) maneuver and is decreased by airflow limitation?
A) FVC (Forced Vital Capacity)
B) FEV1 (Forced Expiratory Volume in 1 second)
C) FEV1/FVC Ratio
D) Peak Expiratory Flow Rate (PEFR)
E) Residual Volume (RV)
Correct Answer: B) FEV1 (Forced expiratory volume in 1 second)
Rationale: FEV1 is the average flow rate during the first second of an FVC maneuver
and is a key indicator of airflow limitation.
Question 6
What spirometry measurement represents the amount of air that can be exhaled during a rapid
forced exhalation after a maximum inhalation?
A) FEV1
B) FEV1/FVC Ratio
C) FVC (Forced Vital Capacity)
D) Inspiratory Capacity (IC)
E) Total Lung Capacity (TLC)
Correct Answer: C) FVC-Forced Vital Capacity
Rationale: FVC is the total amount of air exhaled forcefully after a maximum
inhalation.
, Question 7
How is a client's FVC compared to their peers, and what is the expected minimum percentage?
A) As a raw number; at least 70%.
B) As a percent of predicted; at least 80%.
C) As a ratio; less than 70%.
D) As a percentage of total lung capacity; at least 90%.
E) As an absolute value; at least 3.0 liters.
Correct Answer: B) Percent of predicted of FVC; Should be at least 80%
Rationale: A client's FVC is compared to peers using the percent of predicted, which
should be at least 80%.
Question 8
What is considered a normal FEV1/FVC ratio?
A) Less than 70%
B) Equal to 70%
C) Greater than 70%
D) Greater than 80%
E) Equal to 100%
Correct Answer: C) Normal is >70%
Rationale: A normal FEV1/FVC ratio is greater than 70%.
Question 9
If the FEV1/FVC ratio is less than 70%, what does this typically indicate?
A) Restriction (decreased holding capacity of the lungs).
B) Obstruction (decreased speed of airflow).
