MULTIPLE CHOICE jjj




1. Consequences of ionization in human cells include jjj jjj jjj jjj



1. creation ofunstable atoms. jjj jjj



2. production of free electrons. jjj jjj



3. creation ofhighly reactive free molecules jjj (called free radicals) capable jjj jjj jjj jjj jjj



of producing substances poisonous to the cell.
jjj jjj jjj jjj jjj jjj



4. creation of new biologic molecules detrimental to the living
jjj cell. jjj jjj jjj jjj



5. injury to the cell that may manifest
jjj itself as abnormal function or loss of
jjj jjj jjj jjj jjj jjj jjj jjj jjj



function.

jjj jjj jjj jjj jjj jjj jjj jjj jjj jjj



jjj charged particles by removing orbital electrons from the atom of normal matter
jjj jjj jjj jjj jjj jjj jjj jjj

, through which it passes? a.
jjj jjj jjj jjj



Ionizing radiation jjj



b. Nonionizing radiation jjj



c. Subatomic radiation jjj



d. Ultrasonic radiation jjj




ANS: j j j A

3. Regarding exposure to ionizing radiation, patients who are educated to understand the
jjj jjj jjj jjj jjj jjj jjj jjj



medical benefit of an imaging procedure are more likely to
jjj jjj jjj jjj jjj jjj jjj jjj



a. assume a small chance of biologic damage but not suppress any radiation
jjj jjj jjj jjj jjj jjj jjj



phobia they may
j jj have. jjj jjj jjj



b. cancel their scheduled procedure because they are not willing to assume
jjj a jjj jjj jjj jjj jjj jjj



small chance of biologic damage. jjj jjj jjj jjj



c. suppress any radiation phobia but not risk a small chance of possible biologic damage.
jjj jjj jjj jjj jjj jjj jjj jjj



d. suppress any radiation phobia and be willing to assume a small chance jjj jjj jjj jjj jjj jjj



of possible biologic damage.
j jj jjj jjj

d. 1/10,000 of a sievert. jjj jjj jjj




ANS: j j j C


5. The advantages of the BERT method
jjj are jjj jjj jjj jjj



1. BERT does not imply radiation jjj risk; it is simply a means for comparison. jjj jjj jjj jjj jjj jjj jjj jjj



2. BERT emphasizes that radiation is an innate part of the environment.
jjj jjj jjj jjj jjj jjj jjj



3. BERT provides an answer that is easy for the patient to comprehend. a. 1 and 2 only
jjj jjj jjj jjj jjj jjj jjj jjj

c. 2 and 3 only jjj jjj



d. All the options jjj jjj




ANS: D jjj




6. If a patient asks a radiographer a question about how much radiation he orshe will
jjj jjj jjj jjj jjj jjj jjj jjj



receive from a specific x-ray procedure, the radiographer can
jjj jjj jjj jjj jjj jjj jjj



a. respond by using an estimation based on the comparison of radiation received
jjj jjj jjj jjj jjj jjj



from the x-ray to natural
j jj background radiation
jjj received. jjj jjj jjj jjj jjj



b. avoid the patient’s question by changing the subject.
jjj jjj jjj jjj



c. tell the patient that it is unethical
jjj to discuss such concerns.
jjj jjj jjj jjj jjj jjj jjj jjj jjj



d. refuse to answer the question and recommend that he or she speak with the referring
jjj jjj jjj jjj jjj jjj jjj jjj jjj



physician.

7. Why should the selection of technical exposure factors for all medical imaging
jjj jjj jjj jjj jjj jjj jjj jjj



procedures always follow ALARA?
jjj jjj jjj jjj

jjj j j j jjj j j j j j j
