a)
Pulmonary hypertension
b)
Morbid obesity
c)
Chronic asthma
d)
Pneumonia
2.
Upon the assessment of a patient receiving volume control AC ventilation, you observe a flow-volume loop with a sawtooth pattern on exhalation. Which of the following actions would help this patient the most?
a)
Switch to pressure control ventilation
b)
Administer a bronchodilator
c)
Increase the endotracheal tube cuff pressure
d)
Assess the patient’s need for suctioning
3.
The amount of gas that can be inhaled above the volume that is normally inhaled during quiet breathing is called what?
a)
FRC
b)
ERV
c)
IRV
d)
VC
4.
After reviewing your work order for the day, you notice that you have a patient with chronic bronchitis and another patient with emphysema. Which of the following PFT findings would you expect for these patients?
a)
Increased lung compliance
b)
Decreased forced expiratory flows
c)
Decreased total lung capacity
d)
Decreased diffusing capacity
5.
Upon entering the patient’s room, you heard the physician instruct the patient to “inhale as deeply as possible and then blow out all of the air as hard as you can.” Which pulmonary function test is being performed?
a)
IC
b)
TLC
c)
MVV
d)
FVC
6.
You have been monitoring the vital capacity and maximum inspiratory pressure readings over the last 4 hours of a 39-year-old female patient that is receiving mechanical ventilation. The values have steadily decreased over this time period. How should this be interpreted?
a)
Her condition is worsening
b)
She has undiagnosed asthma
c)
Her strength is improving
d)
She is not giving her best effort
7.
The results of a bedside spirometry test that was performed on a patient reveals the following: Respiratory rate = 19, Tidal volume = 380 mL, Dead space = 145 mL, Vital capacity = 1.1 L. Based on these results, what is the patient’s minute ventilation?
a)
3.4 L/min
b)
4.7 L/min
c)
7.2 L/min
d)
21.3 L/min
8.
You are called to measure the strength of a patient’s respiratory muscles at the bedside. Which of the following devices would you select?
a)
Pressure manometer
b)
Peak flowmeter
c)
Ergometer
d)
Respirometer
9.
Your patient has the following PFT results below: Vital Capacity 54% of predicted, FEV1 76% of predicted, FEV1/FVC ratio 82%, Peak Flow 119% of predicted, Total Lung Capacity 65% of predicted. Which of the following would be the best interpretation of the results?
a)
Restrictive disease only
b)
Obstructive disease only
c)
Bronchitis
d)
Mixed restrictive and obstructive disease
10.
Using spirometry, you tested a 52-year-old female patient before and after a bronchodilator was given. The results show that her FEV1 increased from 62% to 83% of predicted. What do these results indicate?
a)
A fixed airway obstruction is present
b)
The patient has normal diffusion capacity
c)
The patient has a reversible airway obstruction
d)
The patient has a restrictive process
11.
While performing an MIP test on a 19-year-old female patient, she produces the following results after three attempts: Attempt #1: -23 cm H2O, Attempt #2: -42 cm H2O, Attempt #3: -14 cm H2O. Which of the following best explains the patient’s results?
a)
There is a leak at the mouthpiece
b)
The patient has an obstructive disease
c)
The patient has a restrictive disease
d)
The patient isn’t giving a good effort
12.
Which of the following bedside measurements is considered to be the best for assessing the function of the respiratory muscles and mechanical properties of the lungs?
a)
Functional residual capacity
b)
Vital capacity
c)
Maximum inspiratory force
d)
Minute ventilation
13.
You are about to perform a pulmonary function test on a 65-year-old male patient after providing a bronchodilator breathing treatment. It is suspected that the patient has COPD. His results are as follows: FEV1/FVC ratio = 64%, FEV1 = 86% predicted. How would you characterize this patient?
a)
Normal
b)
Mild COPD
c)
Moderate COPD
d)
Severe COPD
14.
A 49-year-old male patient has a vital capacity of 3400 mL, a functional residual capacity of 4600 mL, and an expiratory reserve volume of 1400 mL. What is his residual volume?
a)
8700 mL
b)
2100 mL
c)
3200 mL
d)
5800 mL
