Question 1

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. disconnected gas sampling line

B. dynamic hyperinflation

C. acute decrease in FRC

D. drift in the flow transducer

Correct Answer: C

Question 2

When performing exercise testing on a biologic control, the measurements obtained should be compared with

A. The patient population that will be tested.

B. Predicted values used for the biologic control's height and weight

C. Previous tests performed on the biologic control.

D. At least two other biologic controls being tested.

Correct Answer: C

Question 3

The following data are obtained for a 60-year-old male undergoing an exercise (stress) test on an ergometer:

A pulmonary function technologist should

A. Continue the test since this is a normal cardiopulmonary response.

B. Stop the test because the blood pressure response is abnormal.

C. Stop the test because this is an abnormal VD/VT response.

D. Stop the test because the heart rate is too high after 10 minutes.

Correct Answer: B

Question 4
