ff ff ff ff f f ff ff ff ff ff ff
medical benefit of an imaging procedure are more likely to
ff ff f f ff ff f f ff ff ff ff
a. assume a small chance of biologic damage but not suppress any radiation
ff ff ff ff ff f f ff ff ff ff ff
ff phobia they may have. ff ff ff

small chance of biologic damage.

5. The advantages of the BERT method are
ff ff ff ff ff ff
1. BERT does not imply radiation risk; it is simply a means for comparison.
ff ff ff ff ff ff ff ff ff ff ff ff
2. BERT emphasizes that radiation is an innate part of the environment.
ff f f ff ff ff ff ff ff ff ff
3. BERT provides an answer that is easy for the patient to comprehend.

6. If a patient asks a radiographer a question about how much radiation he or she will
ff ff ff ff ff f f ff ff ff ff ff ff ff ff ff
receive from a specific x-ray procedure, the radiographer can
ff ff ff ff f f ff ff ff f f
a. respond by using an estimation based on the comparison of radiation received
ff ff ff ff f f ff ff ff ff ff ff
from the x-ray to natural background radiation received.
ff ff ff ff ff ff ff f f
b. avoid the patient’s question by changing the subject.
ff ff ff ff ff ff ff
c. tell the patient that it is unethical to discuss such concerns.
ff ff ff ff ff ff ff ff ff ff
d. refuse to answer the question and recommend that he or she speak with
ff ff ff ff ff ff ff ff ff ff ff ff
the referring physician.
ff ff f f
ANS: A ff
7. Why should the selection of technical exposure factors for all medical imaging
ff ff ff ff ff ff ff ff ff ff ff
procedures always follow ALARA?
ff ff f f f f
a. So that referring physicians ordering imaging procedures do not have to
ff ff ff f f ff ff ff ff ff ff
accept responsibility for patient radiation safety.
ff ff f f ff ff f f
b. So that radiographers and radiologists do not have to accept responsibility for
ff ff f f ff f f ff ff ff ff ff f f
, patient radiation safety. ff f f
c. Because radiation-induced cancer does not appear to have a fixed threshold, that
ff f ff ff ff ff ff ff ff ff ff f f
is, a dose level below which a person would have no chance of developing this
ff ff ff ff ff ff ff ff ff ff ff ff ff ff f f
disease. ff
d. Because radiation-induced cancer does have a dose level at which ff f ff ff ff ff ff ff ff ff
individuals would have a chance of developing this disease.
ff ff ff ff ff ff ff f f ff
ANS: C ff
8. The cardinal principles of radiation protection include which of the following?
ff ff f f ff ff ff f f ff ff ff

ANS: D ff
9. In a hospital setting, which of the following professionals is expressly charged by the
ff ff ff ff ff ff ff ff ff ff ff ff ff
hospital administration with being directly responsible for the execution, enforcement,
ff ff ff ff ff ff ff ff ff ff
and maintenance of the ALARA program?

d. Student radiologic technologist ff f f
ANS: C ff
10. Why is a question concerning the amount of radiation a patient will receive during a
ff ff ff ff ff ff ff ff ff ff ff ff ff ff
specific x-ray procedure difficult to answer?
ff ff ff ff f f ff
1. Because the received dose is specified in a number of different units of measure.
ff ff ff ff ff f f ff ff ff ff f f ff ff
2. Because the scientific units for radiation dose are normally not comprehensible by a
ff ff f f ff ff ff ff ff ff ff f f ff
patient.
ff
3. Because the patient should not receive any information about radiation dose.
