3. Patients who have an understanding of the medical benefits of an imaging procedure because
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.

damage.
d. overcome any radiation phobia and be willing to assume a small risk of possible
biologic damage.
ANS: D REF: 8

5. The advantages of the BERT method are:
1. it does not imply radiation risk; it is simply a means for comparison.
, 2. it emphasizes that radiation is an innate part of our environment.
3. the answer given in terms of BERT is easy for the patient to comprehend.
a. 1 and 2 only
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

administration to be directly responsible for the execution, enforcement, and maintenance of
the ALARA program?

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?
1. Because the received dose is measured in a number of different units
2. Because scientific units for radiation dose are not comprehensible by the patient
3. Because the patient should not receive any information about radiation dose
a. 1 and 2 only
b. 1 and 3 only
c. 2 and 3 only
d. 1, 2, and 3
ANS: A REF: 9
11. X-rays are a form of which of the following kinds of radiation?

d. Nonionizing
ANS: B REF: 2
12. The radiographer must answer patient questions about the potential risk of radiation exposure:
a. abruptly to discourage the patient from asking any other questions.
b. evasively so as not to reveal any information about radiation risk.
c. honestly and in understandable terms.
d. with technical terms.
ANS: C REF: 9
13. Radiation phobia can be greatly reduced by explaining the diagnostic radiation dose to the
patient by using the:
a. ALARA method.
b. BERT method.
c. ORP method.
d. TRACE method.
ANS: B REF: 10

practice is justified?
