3. Regarding exposure to ionizing radiation, patients who are educated to understand the me
dicalbenefit of an imaging procedure are more likely to
a. assume a small chance of biologic damage but not suppress any radiation pho
biathey may have.
b. cancel their scheduled procedure because they are not willing7to assume a s
mallchance of biologic damage.
c. suppress any radiation phobia but not risk a small chance of possible biolo
gicdamage.
d. suppress any radiation phobia and be willing to assume a small chance of possi
blebiologic damage.
ANSWER:7 D

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. it provides an answer that 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
ANSWER:7 D
6. If a patient asks a radiographer a question about how much radiation he or she will rec
eivefrom a specific x-ray procedure, the radiographer can
a. respond by using an estimation based on the comparison of radiation received fr
omthe x-ray to natural background radiation received.
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 wit
h thereferring physician.

ance of developing this disease.
