NBRC Registry Examination for Advanced Pulmonary Function Technologists 認定 RPFT 試験問題:

1. A 12-year-old patient completed an evaluation for exercise-induced asthma in the pulmonary function laboratory. The patient completed six minutes of exercise on a treadmill with a heart rate of 145 to 150/min.
The following spirometry data were collected:

A pulmonary function technologist should conclude that the exercise test is

A) Adequate workload with a negative response
B) Inadequate workload with a negative response
C) Inadequate workload with a positive response
D) Adequate workload with a positive response

2. A pulmonary function technologist is reviewing results of a recent mechanical diffusion simul-ation 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?

A) Proceed with testing.
B) Recalibrate the pneumotachometer.
C) Change the calibration gases.
D) Recalibrate the gas analyzer.

3. During a cardiopulmonary stress test using breath-by-breath gas analysis, a pulmonary function technologist notices that the VO2suddenly decreases. Which of the following may explain this change?
1. The patient has achieved anaerobic threshold.
2. The measurement of the expired gas volumes is inaccurate.
3. O2analyzer "phase delay" has increased.
4. There is a leak in the tubing or mouthpiece.

A) 1, 2, and 3 only
B) 1, 3, and 4 only
C) 1, 2, and 4 only
D) 2, 3, and 4 only

4. A pulmonary function technologist is asked to select gas concentrations to simulate pediatric patients' exhaled concentrations during a DLcosimu-lation. Which of the following FECO concentrations should the technologist select?

A) 0.400
B) 0.300
C) 0.200
D) 0.100

5. During a bronchial provocation study, a patient has the following spirometric values after a 0.25 mg/mL dose of methacholine:

Based on these results, a pulmonary function technologist should

A) Instruct the patient to blow out longer and repeat the effort.
B) Stop the test and immediately administer a bronchodilaior.
C) Reduce the concentration of methacholine on the next trial.
D) Instruct the patient to blow out harder and repeat the effort.
