ANS: .A
3. 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

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

ANS: .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

ANS: .C
10. Why . is . a .question .concerning .the . amount . of .radiation .a .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
.patient.
