What are the four steps in the diagnostic problem-solving process: 1. 2. 3. 4. 1. narrowing the search 2. hypothesis activation 3. information seeking 4. hypothesis evaluation
What is the purpose of a cue in narrowing the search? Cues help to focus attention on a suspicious area
When is an image determined to be outside acceptance limits? if the radiographer, supervisor, or other physician determines that an image is not acceptable, it is outside limits of quality.
What is the last stage in the imaging process? a. acquisition b. processing c. analysis d. archiving d. archiving

What individual is trained to create and analyze an image? The radiographer
What step requires that the hypotheses be tested by looking for more information? a. hypothesis evaluation b. information seeking c. hypothesis activation d. narrowing the search field b. information seeking
What is the last step of the diagnostic problem-solving strategy? a. hypothesis activation b. hypothesis evaluation c. information seeking d. narrowing the search field b. hypothesis evaluation
Which of the following is described as a major roadblock in overcoming complex problems such as establishing imaging standards? a. hypothesis evaluation b. quality management c. pyramid problem d. analytical process c. pyramid problem
Which of the following concepts is described as the range of images determined to be of good quality by a given individual or a department? a. analytical process b. quality management c. pyramid problems d. acceptance limits d. acceptance limits
Why might some poor quality images be considered within the acceptance limits? to prevent added exposure to the patient
Which of the following steps in diagnostic problem-solving strategy starts with the review of the complete image to avoid premature narrowing? a. information seeking b. hypothesis activation c. hypothesis evaluation d. narrowing the search field d. narrowing the search field
Acceptable images depends on many factors. If any of those factors are off, it can cause a problem in various other factors, thus a pyramid effect of problems is the result pyramid problem
