| a. | the order in which they were exposed. |
| b. | the order in which they were processed. |
| c. | anatomic order. |
| d. | the order prescribed by the American Dental Association (ADA) nomenclature. |
ANS: C
Radiographs are intended to be placed in a film holder in anatomic order. They are not placed in the film holder in the order in which they were exposed. They are not placed in the film holder in the order in which they were processed. They are not placed in the film holder in the order prescribed by the ADA nomenclature.

| a. | increases the contrast of the radiograph. |
| b. | increases the density of the radiograph. |
| c. | decreases the density of the radiograph. |
| d. | masks the light around each radiograph. |

| a. | the treatment room lights are left on. |
| b. | extraneous light is eliminated. |
| c. | the viewbox light is turned off. |
| d. | films are held up by the operator and viewed through ceiling lights. |
ANS: B
When viewing radiographs, it is easier to detect subtle changes in density and contrast if extraneous light is eliminated. Treatment room lights are a source of extraneous light. Backlighting, as from the viewbox, is preferred. Viewing films through ceiling lights is discouraged.
