✍️ Sample RPFT Questions & Answers
1. A spirometer's volume reading drifts upward by 4.2% over two weeks of biologic controls. What should the technologist do?
A consistent upward drift exceeding the ±3.5% ATS accuracy limit indicates equipment malfunction requiring removal from service and correction.
2. What is the PRIMARY objective of infection control & prevention within the Registered Pulmonary Function Technologist profession?
The primary objective is ensuring quality outcomes through established standards while continuously improving practices and processes.
3. Which flow-volume loop feature most strongly suggests a patient's effort was submaximal at the start of a forced expiratory maneuver?
A rounded rather than sharp PEF spike on the flow-volume loop indicates the patient did not generate a maximal, abrupt initial effort.
4. What is the primary purpose of applying nose clips during spirometry?
Nose clips ensure that all inspired and expired air passes through the mouthpiece, preventing underestimation of volumes due to nasal air leakage.
5. What environmental data must be entered into a spirometry system before testing to allow BTPS correction?
BTPS (Body Temperature, Pressure, Saturated) correction requires ambient temperature, barometric pressure, and humidity to convert measured gas volumes to body conditions.
6. When should clinical assessment & patient care be conducted in Registered Pulmonary Function Technologist?
Regular assessments combined with trigger-based reviews ensure ongoing monitoring while capturing the impact of significant changes.
