particles by removing orbital electrons from the atom of normal matter through which it
passes?

b. Nonionizing radiation
c. Subatomic radiation
d. Ultrasonic radiation
RIGHT ANSWERA
3. Regarding exposure to ionizing radiation, hospital patients who are educated to understand the
medical benefit of an imaging procedure are more likely to
a. assume a small chance of biologic damage but not suppress any radiation phobia
they may have.
b. cancel their scheduled procedure because they are not willing to assume a small
chance of biologic damage.
c. suppress any radiation phobia but not risk a small chance of possible biologic
damage.

biologic damage.
RIGHT ANSWERD
4. The millisievert (mSv) is equal to
a. 1/10 of a sievert.
b. 1/100 of a sievert.
c. 1/1000 of a sievert.

,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 hospital patient to comprehend.
a. 1 and 2 only
b. 1 and 3 only
c. 2 and 3 only
d. 1, 2, and 3
RIGHT ANSWER D
6. If a hospital 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 hospital patient’s question by changing the subject.
c. tell the hospital 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.
RIGHT ANSWER A
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 hospital patient radiation safety.
b. So that radiographers and radiologists do not have to accept responsibility for
hospital patient radiation safety. NURSINGEXAMS
c. Because radiation-induced cancer does not appear to have a dose level below
which individuals would have no chance of developing this disease.
d. Because radiation-induced cancer does have a dose level at which individuals
would have a chance of developing this disease.

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