Bank
Regarding exposure to ionizing radiation, 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.
d. suppress any radiation phobia and be willing to assume a small
chance of possible
biologic damage. -correct answer -->>D. Suppress any radiation
phobia and be willing to assume a small chance of possible biologic
damage.
Consequences of ionization in human cells include
1. creation of unstable atoms.
2. production of free electrons.
,3. creation of highly reactive free radicals capable of producing
substances poisonous to the cell.
4. creation of new biologic molecules detrimental to the living cell.
5. injury to the cell that may manifest itself as abnormal function or loss
of function. -correct answer -->>1, 2, 3, 4, & 5
Which of the following is a form of radiation that is capable of creating
electrically charged particles by removing orbital electrons from the
atom of normal matter through which it passes?
a. Ionizing radiation
b. Nonionizing radiation
c. Subatomic radiation
d. Ultrasonic radiation -correct answer -->>a. Ionizing Radiation
The millisievert (mSv) is equal to
a. 1/10 of a sievert.
b. 1/100 of a sievert.
c. 1/1000 of a sievert.
d. 1/10,000 of a sievert. -correct answer -->>C. 1/1000 of a
sievert
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 -correct answer -->>D. 1, 2, & 3
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. -correct answer -->>A. Respond by
using an estimation based on the comparison of radiation received.
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.
