A pulmonary function technologist is performing an exercise (stress) test on a patient with severe COPD. As the test progresses, the patient shows signs of increasing dyspnea. Measurements of inspiratory capacity decreased from 2.0 L to 1.5 L. Which of the following most likely occurred?

• A.acute decrease in FRC
• B.drift in the flow transducer
• C.disconnected gas sampling line
• D.dynamic hyperinflation

A patient has normal pulmonary and cardiac function. Which of the following is most likely when the patient reaches the anaerobic threshold during incremental stress testing?

• A.Decreased CO2production
• B.Increased VDA/VTratio
• C.Decreased VE
• D.Increased RER

A body plethysmograph box pressure transducer fails the electronic calibration check after multiple attempts.
Which of the following should a pulmonary function technologist do?
1. Perform a biologic control test
2. Inspect the door seal.
3. Re-zero the box pressure transducer.
4. Perform a physical pressure calibration.

• A.1, 2, and 4 only
• B.1, 2, and 3 only
• C.2, 3, and 4 only
• D.1, 3, and 4 only

During an exercise (stress) test, the minute ventilation to carbon dioxide production (Ve /VCO2) ratio is 100.
This measurement indicates

• A.A normal response
• B.Equipment malfunction
• C.Increased work of breathing
• D.Severe pulmonary hypertension

In setting up a CO analyzer, a pulmonary function technologist notices that the analyzer reads -0.03 while sampling air. The technologist should

• A.Adjust the reading to +0.03.
• B.Reverse the sample flow.
• C.Adjust the reading to 0.00.
• D.Accept the reading because it is within ± 3%.
