1. Recent cataract removal surgery
2. Unstable cardiovascular status
4. Hemoptysis of unknown origin
,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
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%
