Question 1

Testing that can catch problems before they may become readily apparent is called ______ maintenance.

Accepted Answer

Routine maintenance involves regularly checking and testing systems to identify and address any potential issues before they escalate into larger problems. Acceptance testing is a type of testing that occurs after development to ensure that a system meets the specified requirements. Error maintenance involves correcting issues that have already been identified. Therefore, the correct answer is A.

Question 2

Where can QC standards be found for what should be monitored in a PACS system?

Accepted Answer

Quality control (QC) standards for PACS systems can be found in various sources such as the American College of Radiology, the American Association of Physicists in Medicine, and the equipment vendor. Therefore, the best choice is D, all of the above.

Question 3

What is most often the weakest link in the digital imaging chain?

Accepted Answer

The monitor is often the weakest link in the digital imaging chain because it is the final output device that displays the image. If the monitor is not calibrated correctly or is of low quality, the image will not be accurately displayed and may appear different from its original form. It is important to use a high-quality, calibrated monitor to ensure the accuracy and consistency of the final image.

Question 4

Most QA activities produce ______ data.

Accepted Answer

QA activities typically involve collecting objective and numeric information, such as defect counts, test case pass rates, and code coverage metrics. This type of information is classified as quantitative data. While some QA activities may involve qualitative data collection (e.g., user feedback on a new feature), the majority of QA activities focus on quantitative data. Equivocal data refers to information that is unclear or open to interpretation, which is not typically the primary focus of QA activities.

Question 5

Which of the following is not a QC activity that should be monitored in a PACS environment?

Accepted Answer

The answer of Which of the following is not a...

Question 6

CQI focuses on ______.

Accepted Answer

CQI (Continuous Quality Improvement) is a management philosophy that focuses on improving processes within an organization rather than solely focusing on individuals or correcting mistakes. Quality improvement is an ongoing process that requires continuous analysis and improvement of processes to achieve better outcomes, increased efficiency, and higher quality of products or services. Therefore, A - Process is the best choice.

Question 7

Quality aspects to be evaluated in radiology include ______-centered characteristics.

Accepted Answer

Quality in radiology should include both patient-centered and product-centered characteristics. People-centered aspects to be evaluated include patient satisfaction, communication with patients, and overall patient experience. Product-centered aspects include image quality, accuracy of the diagnosis, and appropriateness of the imaging exam. Both aspects are equally important in evaluating the quality of radiology services.

Question 8

The ultimate focus in health care is to improve ______ and provide ______ so that patients will want to return.

Accepted Answer

The ultimate focus in health care is to improve patient care and provide high-quality service so that patients will want to return. Health risks and assistance with insurance may be important components of healthcare, but they are not the ultimate focus. Efficiency and employee morale may be important for running a successful healthcare organization, but they are not the ultimate focus in terms of improving patient outcomes and satisfaction.

Question 9

Errors in equipment performance are usually detected by poor ______.

Accepted Answer

Errors in equipment performance are typically detected by poor quality outcomes, as these outcomes directly reflect the equipment's performance.

Question 10

"A comprehensive set of activities designed to monitor and maintain systems that produce a product" is the definition of ______.

Accepted Answer

The answer of "A comprehensive set of activities designed to...

Question 11

Testing performed before newly installed or majorly-repaired equipment can be accepted by the department is called ______ testing.

Accepted Answer

Acceptance testing is done to ensure that the newly installed equipment or repaired equipment meets the required specifications and functions properly before being accepted by the department. Routine testing is done regularly to ensure the equipment is working optimally, while error and problem testing are not standard terms in this context.

Question 12

QA/QC programs focus on ______ quality, whereas CQI focuses on ______ the process.

Accepted Answer

QA/QC (Quality Assurance/Quality Control) programs are designed to maintain quality by ensuring that products or services meet certain standards. CQI (Continuous Quality Improvement), on the other hand, focuses on improving the process to enhance quality over time.

Question 13

A device used to measure the luminescence of areas on the monitor is a ______.

Accepted Answer

A photometer is an instrument used to measure the intensity of light, including luminescence on monitors.

Question 14

Three major categories of QC testing that can be used at various times include ______.

Accepted Answer

The three major categories of QC testing are acceptance testing, routine maintenance, and error maintenance. Option C is the only one that includes all three categories accurately. Option A and D are inaccurate as they use terminologies that do not fall under the categories of QC testing. Option B combines routine and error maintenance, which is not considered as a separate category of QC testing.

Question 15

"A plan for the systematic observation and assessment of the different aspects of a project, service, or facility to make certain that standards of quality are being met" is the definition of ______.

Accepted Answer

Quality assurance involves systematic observation and assessment to ensure that quality standards are met.

Question 16

To make a valid performance measure in any QC activity, documentation must be ______.

Accepted Answer

Keeping documentation up to date is essential to making a valid performance measure in any QC activity. Written in ink, performed by the manager, or kept in a notebook are not necessary factors for valid performance measures.

Question 17

Most health care institutions are accredited by The ______.

Accepted Answer

The Joint Commission is a non-profit organization that accredits and certifies health care organizations in the United States. It sets standards for quality and safety and provides education and support to help organizations improve their performance. The other choices are not involved in accrediting health care institutions.

Question 18

Continuous quality improvement tends to focus on ______ rather than the ______.

Accepted Answer

Continuous quality improvement is a proactive approach that aims to improve processes, systems, and procedures to achieve better outcomes. Therefore, it tends to focus on identifying and improving processes rather than correcting defects or mistakes. This involves a focus on the people involved in the processes and their interactions rather than just the end product or service. Thus, the correct choice is C, process/people.

Question 19

Daily/monthly display monitor testing can be completed by ______.

Accepted Answer

The answer of Daily/monthly display monitor testing can be completed...

Question 20

TJC accreditation is necessary for a hospital to ______.

Accepted Answer

TJC accreditation is necessary for a hospital to hold certain licenses, obtain reimbursements from insurance companies, and receive malpractice insurance.
