If a patient asks a radiographer a question about the potential risk of radiation
exposure associated with a specific x-ray procedure, the radiographer should:
A. use his or her intelligence and knowledge to answer the question honestly and
provide a suitable example that compares the amount of radiation received from the
procedure in question with natural background radiation received over a given period
of time
B. avoid the patient's question by changing the subject
C. tell the patient that it is unethical to discuss such concerns
D. refuse to answer the question and recommend that he or she speak with the
referring physician
