Question 1

In which of the following patients would an end-tidal CO2most likely produce values that are inconsistent with PaCO2?

A.20 year old who smokes cigarettes

B.12 year old with kyphoscoliosis

C.50 year old with mild scleroderma

D.42 year old with moderate COPD

Question 2

A helium dilution test has just been performed on a patient. The following results are obtained:
FRC 5.0 L
VC 4.0 L
ERV 1.5 L
TLC was calculated to be 6.0 L by plethysmography. From this information, a pulmonary function technologist should conclude that the patient

A.Had inadequate intrapulmonary mixing of inspired gas, resulting in an erroneous FRC.

B.Did not perform the slow vital capacity properly, resulting in too low an FRC by helium dilution.

C.Was turned into the helium dilution circuit at a lung volume considerably above FRC.

D.Did not remain in the helium dilution breathing circuit long enough for equilibration.

Question 3

A pulmonary function technologist is performing quality control on a nebulizer used in the 5breath dosimeter bronchial challenge. The target output of the device is 0.09 mL, plus or minus 10%. After 10 actuations, the nebulizer output was 75uL with a 2.0 mL initial saline dose in the nebulizer. The technologist should

A.Add an exhalation filter and proceed with testing patients.

B.Open the vent before starting the bronchial challenge.

C.Clean and reevaluate this nebulizer.

D.Accept the results and begin using the device.

Question 4

During daily quality control procedures on an infrared CO2analyzer, a pulmonary function technologist is unable to adjust the gain to the calibration gas concentration. Which of the following is the most likely explanation?

A.Water droplets in the sample cell

B.Saturation of the soda lime

C.Increased gas sampling rate

D.Presence of high levels of oxygen

Question 5

When performing quality control in a body plethysmograph using a 5-L isothermal bottle, the VTG at shutter closure are as follows:

A pulmonary function technologist should

A.Service the mouth pressure transducer.

B.Recalibrate the box pressure transducer.

C.Check biological control before beginning testing.

D.Proceed with patient testing.
