Question 1

Which continuous quality improvement model was originally developed by W. Edwards Deming and later refined for healthcare applications?

Accepted Answer

Plan-Do-Study-Act (PDSA)

Answer

The PDSA cycle was developed by Deming (building on Shewhart's work) and is widely adopted in healthcare quality improvement.

Question 2

A fishbone (Ishikawa) diagram used in respiratory education QI is designed to:

Accepted Answer

Identify and categorize potential root causes of a problem

Answer

A fishbone diagram visually maps potential causes of a problem into categories (people, process, equipment, environment), facilitating root cause identification.

Question 3

In Six Sigma quality methodology, the term 'sigma level' describes:

Accepted Answer

The number of standard deviations between the process mean and the nearest specification limit

Answer

Sigma level measures process capability by indicating how many standard deviations fit between the mean and the specification limit, with higher sigma indicating fewer defects.

Question 4

A respiratory education department uses 'chart audits' as part of its QI program. The primary purpose is to:

Accepted Answer

Verify that documentation meets established standards and reflects actual care provided

Answer

Chart audits systematically review documentation to assess compliance with standards, identify gaps, and ensure care documentation accurately reflects education delivered.

Question 5

When evaluating the reliability of a respiratory education assessment tool, 'test-retest reliability' means:

Accepted Answer

The same test given twice to the same group produces consistent results

Answer

Test-retest reliability assesses the stability of scores when the same instrument is administered to the same individuals on two separate occasions under similar conditions.
