  1. A patient's digital pulmonary rehabilitation platform shows declining step counts and session completion rates over two weeks. The educator's BEST response is to:

    Answer: Schedule a motivational check-in to identify barriers and adjust the program

    Declining engagement metrics signal barriers that require a supportive check-in to identify and address root causes before adjusting the program.

  2. Which capnography waveform pattern is characteristic of bronchospasm or COPD exacerbation?

    Answer: A 'shark fin' waveform with a sloped, gradual rise to peak ETCO2

    The 'shark fin' (sloped expiratory upstroke) pattern reflects uneven CO2 emptying due to airway obstruction in bronchospasm or COPD.

  3. A remote patient monitoring program transmits nightly pulse oximetry data. Which value should trigger an automated alert to the care team per standard protocols?

    Answer: SpO2 below 88% for more than 5 minutes

    SpO2 sustained below 88% is the standard threshold for clinically significant nocturnal hypoxemia requiring evaluation.

  4. When conducting a virtual inhaler technique assessment via video, the educator notes they cannot verify the patient's inspiratory flow rate. The BEST solution is:

    Answer: Mail an In-Check DIAL or similar training device so flow can be quantified at the next visit

    Mailing a low-tech inspiratory flow training device enables objective flow assessment at a subsequent in-person or virtual session.

  5. A respiratory educator reviews oscillometry (impulse oscillometry, IOS) results. Elevated R5-R20 difference primarily indicates:

    Answer: Peripheral (small) airway resistance disproportionate to central airway resistance

    R5 measures total (central + peripheral) resistance while R20 reflects mainly central airways; an elevated R5-R20 difference indicates peripheral airway disease.

  6. A digital asthma action plan app allows patients to log symptoms and PEF daily. Which feature is MOST critical for safety?

    Answer: Automated color-zone thresholds that prompt the patient to contact their provider or call 911

    Automated action-zone thresholds that escalate to provider contact or emergency services are the safety-critical feature in digital asthma action plans.

  7. Which interoperability standard enables EHR systems from different vendors to exchange respiratory function test results?

    Answer: HL7 FHIR (Fast Healthcare Interoperability Resources)

    HL7 FHIR provides a standardized API framework that enables different EHR systems to exchange structured clinical data, including pulmonary function results.
