Multiple Choice ANSWERS
1. d. Although the dentist, dental assistant, and dental hygienist can all perform periodic quality control tests on the dental x-ray machine, equipment regulations usually specify that inspections be done by a qualified radiological expert licensed by the state.
2. a. Established in 1981 and updated in 1991, the federal Consumer-Patient Radiation Health and Safety Act established guidelines regarding who can place and expose radiographs.
3. c. Providing all radiographers with a radiation monitoring badge, whether required by law or not, is a good risk-management tool. Monitoring lack of exposure provides the practice with documentation of safe work habits.
4. d. The Consumer-Patient Radiation Health and Safety Act established minimum standards for state certification and licensure of personnel who administer radiation in medical and dental radiographic procedures. The intent of the act was to minimize unnecessary exposure to potentially hazardous radiation.
5. b. The patient must be informed as to who will be exposing the radiographs, but they do not need to be provided with the option of selecting the radiographer.
6. b. Such documents are not valid because the patient cannot legally consent to negligent care.
7. d. Ethics is defined as a sense of moral obligation regarding right and wrong behaviors. Professional ethics supplement legal guidelines and regulations regarding the behavior of health care professionals.
