RPFT Registered Pulmonary Function Technologist Free Practice Test — 30 Questions

Question 1

A Registered Pulmonary Function Technologist is scheduled to perform a full diagnostic spirometry battery on a patient presenting for a routine follow-up. Upon entering the testing room, the technologist observes the patient exhibiting significant shortness of breath, audible wheezing, and appears to be in moderate distress, stating they feel \"much worse than usual.\" What is the most ethically sound and clinically appropriate immediate course of action for the technologist?

Accepted Answer

Postpone the spirometry testing until the patient's acute symptoms subside and they are clinically stable.

Question 2

A registered pulmonary function technologist is conducting spirometry on a patient who requires supplemental oxygen via a nasal cannula. During the forced vital capacity maneuver, the technologist observes a slight but consistent leak around the patient\'s nares from the nasal cannula tubing. Considering the principles of volume measurement in spirometry, what is the most likely direct consequence of this unaddressed leak on the recorded pulmonary function test results?

Accepted Answer

An underestimation of the patient's forced vital capacity (FVC) and related volume measurements.

Question 3

Following a routine daily calibration check of a spirometer using a 3.0 L volume syringe, the device consistently registers volumes that are 0.2 L lower than the delivered volume across a range of flow rates (e.g., 2 L/s, 4 L/s, 6 L/s). The RPFT notes this persistent discrepancy. What is the most appropriate immediate course of action?

Accepted Answer

Immediately recalibrate the spirometer according to manufacturer specifications and re-verify calibration.

Question 4

Following a recent mandate from the National Institute for Occupational Safety and Health (NIOSH) requiring all accredited pulmonary function laboratories to transition to an automated calibration verification system (ACVS) for spirometry, Anya, a seasoned RPFT, is tasked with spearheading the implementation in her department. The ACVS employs a novel digital flow sensor and a standardized simulated lung model, a significant departure from the previous manual syringe-based method.

Question 20

A Registered Pulmonary Function Technologist is evaluating a patient presenting with exertional dyspnea and suspected restrictive lung disease. Initial spirometry reveals slightly reduced FEV1/FVC ratios, but the FVC maneuver shows significant variability and early termination, making reproducibility criteria difficult to meet. The patient reports no significant improvement after a standard bronchodilator administration. The technologist suspects that air trapping or significant intrinsic lung disease might be confounding the spirometry results. Which of the following diagnostic pathways best reflects the technologist\'s need to demonstrate adaptability, advanced problem-solving, and a comprehensive approach to pulmonary function assessment in this ambiguous scenario?

Accepted Answer

Perform lung volume measurements via plethysmography or helium dilution and assess diffusing capacity (DLCO).

Question 21

A physician urgently requests that a pulmonary function technologist deviate from the standard protocol for spirometry by allowing the patient to take a single, maximal exhalation followed by a short inspiratory hold before the forced exhalation begins, citing a belief that this specific maneuver will better capture an elusive bronchospastic response in a patient with atypical symptoms. The technologist is aware that this modification is not part of any recognized PFT guideline. What is the most appropriate course of action for the technologist in this situation?

Accepted Answer

Politely decline the request, explain the importance of adhering to standardized PFT protocols for data validity and reproducibility, and offer to perform the test according to established guidelines, while also offering to document the physician's specific concerns for further discussion.

Question 22

Following the publication of a pivotal study in a leading respiratory journal, the pulmonary function laboratory where you work is mandated to revise its bronchodilator response testing protocol.
