What is the primary problem in obstructive lung disease? Correct Answer-
Increased airway resistance
Which of the following measure is typically increased in patients with restrictive
lung disease? Correct Answer-Pressure needed to expand the lung
You perform a series of pulmonary function tests on a patient with a potentially
infectious disease carried via the airborne route. Which of the following
infection-control procedures should you implement?
1. Wear a respirator or close-fitting surgical mask.
2. Dispose of, sterilize, or disinfect the tubing circuit after testing.
3. Clean the interior surface of the spirometer before the next test. Correct
Answer-1. Wear a respirator or close-fitting surgical mask.
2. Dispose of, sterilize, or disinfect the tubing circuit after testing.
Which of the following pulmonary function devices directly collect and measure
gas volumes?
1. Water-sealed spirometer
2. Dry rolling-seal spirometer
3. Bellows spirometer
, PFT Exam with Complete Solutions
4. Pneumotachometer Correct Answer-1. Water-sealed spirometer
2. Dry rolling-seal spirometer
3. Bellows spirometer
To what does the range or limit of a device's measuring ability refer? Correct
Answer-Capacity
How closely a device measures a certain reference value refers to what quality?
Correct Answer-Accuracy
What would you use to determine the accuracy of a water-sealed spirometer in
measuring lung volumes? Correct Answer-Calibrated 3-L syringe
While checking the accuracy of a portable spirometer for volumetric measures
with a calibrated super syringe, you obtain a mean measured value of 2.7 L.
What is the percent error of this instrument? Correct Answer-10%
What is the ability of a measuring device to consistently provide the same
measure of the same quantity? Correct Answer-Precision
