Question 1

A special indirect measurement procedure must be done to find the following:
A) Inspiratory reserve volume
B)Residual volume
C)Expiratory reserve volume
D)Inspiratory capacity

Accepted Answer

B

Question 2

Overall characteristics of pulmonary function testing results on a patient with obstructive lung disease include that: A) FEV₁ is reduced and FEV₁% is normal. B)FEV₁ and FEV₁% are both increased. C)FEV₁ and FEV₁% are both reduced. D)FEV₁ is increased and FEV₁% is decreased.

Accepted Answer

Pulmonary function testing results on a patient with obstructive lung disease typically show a reduction in both FEV1 and FEV1% because the airway is partially obstructed, and it takes more effort for the patient to exhale. This leads to a decrease in the volume of air that can be exhaled in the first second (FEV1) and a decrease in the percentage of vital capacity that can be exhaled in the first second (FEV1%). Therefore, choice C is the correct answer.

Question 3

Your patient has obstructive lung disease. In response to this, which of the following are typically found?
1) Decreased lung compliance
2) Increased ventilatory rate
3) Increased tidal volume
4) Decreased ventilator rate
A)3, 4
B)2, 3
C)1, 2
D)1, 3, 4

Accepted Answer

A

Question 4

All of the following are true of the peak expiratory flow rate test EXCEPT:
A) it is effort dependent.
B)it is taken from the FVC test results.
C)it is taken from the MVV test results.
D)it assesses large upper airways.

Accepted Answer

Peak expiratory flow rate test is not taken from the MVV (maximum voluntary ventilation) test results but rather it is a separate test which measures the maximum flow rate at which a person can exhale forcefully after a full inspiration. It is effort dependent and helps to evaluate airflow limitation in the large upper airways.

Question 5

Which of the following forced vital capacity test times should be interpreted as normal?
A) Less than 4 seconds
B)4 to 6 seconds
C)6 to 8 seconds
D)8 to 10 seconds

Accepted Answer

A normal adult will exhale a forced vital capacity (FVC) within 4 to 6 seconds. Patients with restrictive lung diseases may blow out the FVC in less than 4 seconds. Patients with obstructive lung diseases will need more than 6 seconds to blow out the FVC.

Question 6

Pulmonary function studies are done for all of the following measurements EXCEPT:
A) the patient's carbon monoxide level.
B)lung volumes and capacities.
C)pulmonary diffusion capacity.
D)forced expiratory flow rates.

Accepted Answer

Pulmonary function studies include measurements of lung volumes and capacities, pulmonary diffusion capacity, and forced expiratory flow rates. However, measuring the patient's carbon monoxide level is not a part of pulmonary function studies.

Question 7

The pulmonary diffusion capacity of carbon monoxide test is used to:
A) assess the patient's blood carbon monoxide level.
B)remove carbon monoxide from the patient's blood.
C)measure the residual volume.
D)assess the alveolar-capillary membrane.

Accepted Answer

The pulmonary diffusion capacity of carbon monoxide test is used to assess the alveolar-capillary membrane by measuring the diffusion of carbon monoxide from alveoli into red blood cells in the pulmonary capillaries. It is not used to assess the patient's blood carbon monoxide level, remove carbon monoxide from the patient's blood, or measure the residual volume.

Question 8

Total lung capacity is composed of all of the following EXCEPT:
A) IRV.
B)IC.
C)ERV.
D)RV.

Accepted Answer

ATotal lung capacity (TLC) can be calculated by adding IC, ERV, and RV.

Question 9

In response to a restrictive lung disorder, the following are typically found:
1) Decreased lung compliance
2) Increased ventilatory rate
3) Decreased tidal volume
4) Decreased lung rigidity
A)1
B)2, 3
C)2, 3, 4
D)1, 2, 3

Accepted Answer

Restrictive lung disorders are characterized by decreased lung compliance, leading to increased ventilatory rate and decreased tidal volume as the lungs cannot expand fully.

Question 10

The FEF 25%-75% is used to evaluate:
A) flow in large airways.
B)restrictive lung disease.
C)maximum breathing effort.
D)flow in medium-size to small airways.

Accepted Answer

FEFS1U1B125%-75% stands for forced expiratory flow between 25% and 75%, which is used to evaluate the flow in medium-size to small airways. Therefore, the correct choice is D.
