The traditional unit of exposure is the roentgen, while the SI unit is the:
a. coulomb/kg of air
b. rad
c. rem
d. curie

coulomb/kg of air
Roentgen or coulomb/kg measures ionization of air molecules
Which of the following tumors originates in osseous tissue?
a. Ewing's sarcoma
b. chondrosarcoma
,c. fibrosarcoma
d. chordoma
Give this one a try later!
chondrosarcoma
Osseous tumors originate in hard bone, spongy bone, and cartilage.
Chondrosarcoma's originate in cartilage tissue.
Using a stethoscope alone would assess:
a. pulse rate
b. blood pressure
c. pathogen load
d. pulmonary and cardiac sounds

pulmonary and cardiac sounds
During treatment requring the use of whole abdomen fields, the structure at the
greatest risk for latent effects after 44 Gy is the:
a. liver
b. kidney
c. pancreas
d. gallbladder

kidney
, tolerance doses of the kidney and liver are low. TD 5/5 for the whole liver is
about 30 Gy whereas the TD 5/5 for the kidney is 23 Gy.
Which of the following would be considered a typical alpha/beta ratio for early
responding tissue?
a. 1.5 Gy
b. 3 Gy
c. 5 Gy
d. 10 Gy
Give this one a try later!
10 Gy
The linear quadratic relationship between radiation effect and dose
indicates a larger alpha/beta ratio for early responding tissue
The use of barium would not be indicated in a patient who has suspected:
a. bowel perforation
b. diabetes
c. congestive heart failure
d. renal failure
Give this one a try later!
Bowel perforation
since barium is inert, it is not advisible to use it for GI studies in patients
with bowel perforation or obstruction
