  1. A respiratory educator reviews spirometry data showing an FEV1/FVC ratio of 0.65 post-bronchodilator. How should this finding be classified?

    Answer: Obstructive pattern

    An FEV1/FVC ratio below 0.70 post-bronchodilator confirms obstructive airflow limitation per GOLD criteria.

  2. When analyzing peak flow variability data, a diurnal variation greater than what percentage is generally considered significant for asthma diagnosis?

    Answer: 20%

    Peak flow diurnal variability greater than 20% is a significant indicator of airway instability consistent with asthma.

  3. A CRE is evaluating a patient's 6-minute walk test results over three visits. Distance decreased from 420m to 380m to 350m. What trend does this data suggest?

    Answer: Progressive decline in exercise tolerance

    A consistent decrease in 6MWT distance across serial measurements indicates progressive decline in functional exercise capacity.

  4. Which statistical measure is most appropriate to report when summarizing FEV1 percent predicted values across a heterogeneous patient population?

    Answer: Median with interquartile range

    Median with IQR is preferred for skewed or heterogeneous distributions, providing a more robust central tendency estimate.

  5. A pulmonary rehab program reports a 15% improvement in 6MWT distance. Which additional data point would best contextualize clinical significance?

    Answer: Minimal clinically important difference (MCID)

    The MCID for 6MWT (approximately 25-35m) determines whether a percentage change reflects a meaningful clinical benefit.

  6. In an educational program outcome report, a CRE notes that 60% of COPD patients achieved target inhaler technique scores. What type of data is this?

    Answer: Proportional/rate data

    A percentage of patients achieving a target represents proportional data, expressing outcomes as rates or proportions.

  7. A respiratory educator compares pre- and post-education SpO2 readings during exercise. Which statistical test is most appropriate for this paired data?

    Answer: Paired t-test

    A paired t-test is used to compare means from the same subjects measured at two time points, controlling for individual variability.
