they received factual information about the study before having the examination are more
likely to:
a. assume a small risk of biologic damage but not overcome any radiation phobia
they may have.
b. cancel their scheduled procedure because they are not willing to assume a small
risk of biologic damage.
c. overcome any radiation phobia but not assume a small risk of possible biologic
damage.

b. 1 and 3 only
c. 2 and 3 only
d. 1, 2, and 3
ANS: D REF: 9
6. 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.
ANS: A REF: 9
7. Which of the following is the intention behind the ALARA concept?
a. To keep radiation exposure and consequent dose at the highest possible level
b. To keep radiation exposure and consequent dose at an average level

d. Student radiologic technologist
ANS: C REF: 8
, 10. Why is a question about the amount of radiation a patient will receive during a specific x-ray
procedure difficult to answer?
