NBRC RPFT (Registry Examination for Advanced Pulmonary Function Technologists) Exam is a certification exam for those who wish to become advanced pulmonary function technologists. RPFT exam assesses the knowledge and skills of individuals who work in the field of pulmonary function testing. RPFT exam is designed to ensure that candidates have the necessary skills to perform and interpret pulmonary function tests, as well as to evaluate and manage patients with respiratory diseases.

Q15. A pulmonary function laboratory routinely tests five subjects as biologic controls. Acceptable instrument performance over time is indicated when measurements

For each individual are within 2 standard deviations of the mean of previous measurements for each individual.

For an individual are within 2 standard deviations of the mean of those for the group.

Of the group as a whole agree with those predicted by linear regression for changes in age.

Are within the 95% confidence interval predicted for an individual being tested.

Q16. Airways resistance and specific conductance tests are requested for a 7-year-old child with asthma. Which of the following techniques is preferred?

Panting with body plethysmography

Quiet breathing with body plethysmography

Interrupter

Oscillation

Q17. A comparison of two techniques for measuring Rawis shown below:

Which of the following should a pulmonary function technologist conclude?

Subject 1 panted too forcefully.

The system was calibrated for quiet breathing.

Subjects 1 and 2 both have reactive airways.

Results are consistent with the two methodologies.

Q18. Using a peak flowmeter, a pulmonary function technologist obtains the following:
The technologist should

Conclude that bronchodilatation has occurred.

Report the average of the two best efforts.

Perform at least one more peak flow trial.

Report the patient’s peak flow as 750 L/min.

Q19. A pulmonary function technologist is reviewing an asthma action plan. The patient takes a low-dose inhaled corticosteroid and a long-acting beta2-agonist twice daily. The patient’s personal best peak flow is 600 L/min.
Which of the following instructions should be given to the patient when the peak flow drops to 500 L/min?

Add montelukast (Singular).

Continue the current regimen.

Go to the emergency department.

Double the steroid dose.

Explanation/Reference:

Q20. A pulmonary function technologist reviews the following home monitoring spirometry results:

Use alternative medicine such as acupuncture.

Add a trial of bupropion (Zyban).

Increase the dosage of the nicotine replacement.

Q23. A 35-year-old healthy male is performing a maximal stress test as part of an annual physical. The following data are observed:
