D
(Chp 01) 6. If a patient asks a radiographer a question about how much radiation
he or she will receive from a specific x-ray procedure, the radiographer can
a. respond by using an estimation based on the comparison of radiation received
from the 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 with the
referring physician.
A
(Chp 01) 7. Why should the selection of technical exposure factors for all medical
imaging procedures always follow ALARA?
a. So that referring physicians ordering imaging procedures do not have to
accept responsibility for patient radiation safety.
b. So that radiographers and radiologists do not have to accept responsibility for
patient radiation safety.
c. Because radiation-induced cancer does not appear to have a dose level below
which individuals would have no chance of developing this disease.

would have a chance of developing this disease.

c. Radiation Safety Officer
d. Student radiologic technologist
C
(Chp 01) 10. Why is a question concerning the amount of radiation a patient will
receive during a specific x-ray procedure difficult to answer?

measure

comprehensible by a patient
3. Because the patient should not receive any information about radiation dose
