• Question 101:

  The syndrome of stockpiling is proven to be ineffective and inefficient. It also creates quality issues. This approach provides little value to the data collection effort and is one of the biggest mistake quality improvement teams make.

  Rather than provide a rich source of information, this approach unnecessarily derives up:

  A. The cost of data collection

  B. Create data management issues

  C. Overwhelms the quality improvement teams with too much information

  D. All of the above

  Correct Answer: D

• Question 102:

  A data analyst, using a clinical decision support system (administrative database), discovered a higherthan-expected incidence of renal failure (a serious complication) following coronary artery bypass surgery. The rate was well above 10 percent for the most recent 12 months increased over the last six quarters. However, the clinical decision support system did not contain enough detail to explain whether this complication resulted from the coronary artery bypass graft procedures or was a chronic condition present on admission.

  To find the answer, the data analyst uses different steps. This example illustrates:

  A. How an administrative system's cost effectiveness can be combined with the detailed information in a medical record review?

  B. How data analyst use review chart to isolate cases

  C. That data should be thorough

  D. Computer aided information systems are better to gather data

  Correct Answer: A

• Question 103:

  Generally, medical record review and prospective data collection are considered the most time-intensive and expensive ways to collect information.

  Many reserve these methods for highly specialized improvement projects or use them to answer questions that have:

  A. Surfaced following review of administrative data sets

  B. Use rule-based software development

  C. Combine code and chart based on the overall population

  D. Situation related characteristics

  Correct Answer: A

• Question 104:

  Which of the following is NOT out of Quality measurement categories or domains?

  A. Clinical quality (including both process and outcome measures)

  B. Financial performance

  C. Operational status

  D. patient satisfaction

  Correct Answer: C

• Question 105:

  The cockpit of an airplane is a more complex example of a collection of instruments that reports information critical to successful air travel. The driver of a car or the pilot of an airplane monitors multiple indicators of performance simultaneously to arrive at the intended destination successfully. At any given point in the journey, the driver or pilot may focus on one indicator, but overall success depends on the collective performance of the systems represented by the indicators.

  This example depicts that dashboard tools that report on the ongoing performance of the critical processes that lead to:

  A. Organizational success

  B. Its own success

  C. Organization success rather than on the success itself

  D. Past performance rather than real time performance

  Correct Answer: C

• Question 106:

  Statistical analysis conducted with control charts is different from what some consider "traditional research" (e.g. hypothesis testing, development of p-values, design of randomized clinic trials). Traditional research is designed to compare the results at time one (e.g. the cholesterol levels of a group of middle-aged men) with the results at time two (typically months after the initial measure).

  Research conducted in this manner is referred to as ___________________.

  A. Static group comparison

  B. Continuous distribution

  C. SPC

  D. None of these

  Correct Answer: A

• Question 107:

  Quota sampling was developed in the late 1930s and used extensively by the Gallup organization. Babbie (1979) describes the steps involved in developing a quota sample.

  All of the following are out of those steps EXCEPT:

  A. Develop a matrix describing the characteristics of the target population. This may entail knowing the proportion of male and female; various age, racial and ethnic proportions; as well as the education and income levels of the population

  B. Once the matrix has been created and a relative proportion assigned to each cell in the matrix, data are collected from persons having all the characteristics of a given cell

  C. All persons in a given cell are then assigned a weight appropriate to their proportion of the total

  D. When all the sample elements are so weighted, the overall data should provide a reasonable representation of the majority of the samples

  Correct Answer: D

• Question 108:

  A random sampling also can be drawn by placing equally sized pieces of paper with a range of numbers on them (e.g., 1 to 100) in a bowl and picking a predetermined number to be the sample.

  The problem with simple random samples is that:

  A. They may under represent segments of population

  B. They may over represent segments of population

  C. They may over or under-represent segments of population

  D. They cannot truly depict the samples

  Correct Answer: C

• Question 109:

  Convenience sampling produces a biased sample that is basically a collection of anecdotes that cannot be applied generally to larger populations.

  Convenience sampling is also known as:

  A. Quota sampling

  B. Judgment sampling

  C. Expert sampling

  D. Chunk sampling

  Correct Answer: D

• Question 110:

  Systematic sampling is achieved by numbering or ordering each element in the population (e.g., time order, alphabetical order, and medical order) and then selecting every kth element.

  The key point that most people ignore when doing a systematic sample is that:

  A. The starting point for selecting every kth element should be guaranteed through a random process and should be equal to or less than k but greater than zero.

  B. The starting point for selecting every kth element should be guaranteed through a random process and should be less than k but greater than zero.

  C. The starting point for selecting every kth element should be guaranteed through a random process and should be greater than zero.

  D. The starting point for selecting every kth element should be guaranteed through a random process and should be equal to or greater than zero.

  Correct Answer: A
