• Question 21:

  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.

• Question 22:

  The following results are obtained from an adult patient:

  

  Which of the following is the best interpretation of these values?

  A. Small airway disease

  B. Normal values

  C. Combined obstruction/restriction

• Question 23:

  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.

  Correct Answer: A

• Question 24:

  A pulmonary function technologist is reviewing results of a recent mechanical diffusion simulation using a 3-liter syringe. The test was conducted at a room temperature of 22?C. The following BTPS results were reported: Which of the following should the technologist do?

  B. Change the calibration gases.

  C. Recalibrate the gas analyzer.

  D. Recalibrate the pneumotachometer.

  Correct Answer: A

• Question 25:

  While reviewing exercise data, a pulmonary function technologist notes that the patient's anaerobic threshold occurred at 35% of the patient's VO2MAX. This indicates the patient has

  A. ventilatory limitation

  B. cardiac limitation

  C. a normal response to exercise

  D. given a submaximal effort

  Correct Answer: B

• Question 26:

  A physician orders smoking cessation counseling for a 60-year-old male with a new diagnosis of CHF and COPD. The patient has failed several attempts to quit smoking using nicotine gum. Which of the following should a pulmonary function technologist recommend?

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

  C. Clean and reevaluate this nebulizer.

  D. Accept the results and begin using the device.

  Correct Answer: D
