  1. A CRE is preparing a quality improvement report on inhaler technique errors. Which chart type best displays the most frequent errors in descending order?

    Answer: Pareto chart

    A Pareto chart ranks categories by frequency in descending order and includes a cumulative percentage line, ideal for prioritizing quality improvement targets.

  2. When reviewing spirometry reference equations for a 45-year-old African American female, which factor is critical to apply correctly?

    Answer: Race/ethnicity-adjusted reference values

    Race/ethnicity-specific reference equations are required because population-based norms differ across ethnic groups for accurate percent-predicted calculations.

  3. A CRE notices that asthma control questionnaire scores improved significantly in the first month but plateaued afterward. This pattern best represents which phenomenon?

    Answer: Ceiling effect

    A ceiling effect occurs when scores cluster near the maximum possible value, limiting the ability to detect further improvement.

  4. When calculating a program's COPD readmission rate, the denominator should include which patient group?

    Answer: All COPD patients discharged from the hospital during the reporting period

    The denominator for readmission rate includes all eligible discharged COPD patients in the period, regardless of program completion.

  5. A respiratory educator finds that arterial blood gas pH values in a dataset are not normally distributed. Which measure of central tendency should be reported?

    Answer: Median

    Median is preferred for non-normally distributed continuous data because it is not influenced by outliers or skewness.

  6. A CRE is analyzing data showing that high-risk COPD patients who completed education had 40% fewer ER visits. This type of analysis is best described as:

    Answer: Retrospective cohort analysis

    Analyzing existing patient records comparing outcomes between groups over time is a retrospective cohort analysis.

  7. Which COPD assessment tool provides data that can be plotted to show disease severity distribution across a patient population?

    Answer: BODE index

    The BODE index integrates BMI, obstruction, dyspnea, and exercise capacity into a validated COPD severity score suitable for population-level reporting.
