Chapter 19 Flashcards
Which of these statements is false regarding chemical labels?
C) Chemical labels must be at least 3 inches by 5 inches in size.
There is no regulation on the size of these mandatory labels.
Switching from film-based radiography to a digital imaging system will eliminate the need for managing each of the following except one. Which one is the exception?
A) Disinfectant.
Low- or intermediate-level disinfectants are commonly used to prepare clinical contact surfaces prior to radiographic procedures.
In most locations, who must perform x-ray machine testing according to state and local regulations?
A qualified health physicist.
A qualified health physicist will conduct tests on dental x-ray machines prior to renewing a registration or license.
Can the dental radiographer play a role in monitoring the x-ray machine?
TRUE.
The radiographer who uses the machine on a daily basis should also play a role in monitoring the x-ray machine.
When not in use, how should the x-ray unit support arm be positioned?
FALSE.
The support arm of the x-ray generator should be folded in the closed position with the PID pointing down.
Are quality control calibrations needed for computer monitors used to view digital images?
TRUE.
Quality control calibrations ensure proper resolution and gray scale.
Should the darkroom be evaluated to ensure it is free from chemical fumes?
TRUE.
The darkroom should be evaluated for conditions that create film fog.
What is the definition of quality control in dental radiography?
Quality control is a series of tests to ensure that the radiographic system is functioning properly.
It ensures that the radiographs produced are of an acceptable quality.
What is the purpose of a product label according to the OSHA Hazard Communication Standard?
Chemical product manufacturers must provide warning labels.
Labeling products assists the radiographer in safe management of these products.
What does the outline of a coin on the processed film used in the coin test indicate?
A failed test.
The coin test is used to determine safelight adequacy.
What is the key to peak performance of an automatic processor?
Maintenance.
The unit manufacturer will recommend maintenance and cleaning procedures.
Which processing solution is most critical and demands careful attention?
Developer.
When the developer deteriorates, the underdeveloped radiographic images lighten.
What is quality assurance in dental radiography?
Quality assurance is defined as the planning, implementation, and evaluation of procedures used to produce high-quality radiographs.
It helps to increase the quality of radiographs produced and decrease the incidence of retake radiographs.
What is a reference film?
A reference film is a radiograph processed under ideal conditions.
It is used to compare periodically subsequent films.
