MULTIPLECHOICE
1. The use of x-rays to create a medical image on patients is referred to as
a. electrocardiography.
b. radiography.
c. sonography.
d. magnetic resonance imaging.
ANS: B
Radiography is the making of records of internal structures of the body by passage of x-
rays or gamma rays through the body. These records or images are typically referred to as
radi ographs.
REF: p. 4
2. Particular care must be taken when using radiation for medical imaging. This is the result ofjl jl
ra diation’s ability to create in human tissue and possible biochemical jl
changes.
a. ionizations
b. radio waves
c. sound waves
d. thermal changes
ANS: A
Some forms of electromagnetic energy, including x-
jl
rays, have the ability to ionize atomsin matter. These ionizations have the ability to disrupt
jl
the composition of matter and are capable of disrupting life processes. Special protection
should be provided to prevent excessive exposure to ionizing radiation.

REF: p. 3
3. In the diagnosis of patient disease states, physicians can select from an array of medical
jl
diagn ostic modalities. Afew of these involve the use of ionizing energy to create a medical
jl
image. I f a physician is concerned about the use of ionizing radiation, he or she may choose
jl jl jl jl jl
to order an y of the following diagnostic modalities EXCEPT
jl
a. thermograms.
b. medical sonography.
c. radiography.
d. magnetic resonance imaging.
ANS: C
Radiography involves the use of x-
rays for the production of medical images. Medical procedures such as thermograms,
sonogra ms, and magnetic resonance scans use nonionizing energy forms and consequently
jl
do not prod uce ionizations in human tissue. They are regarded as nonionizing modalities for
jl jl jl
imaging and o ffer excellent alternatives to physicians concerned about radiation exposure to
jl jl
patients.
, REF: pp. 3-4
4. The Greek physician Hippocrates is regarded as the father of Western medicine.All of
the fol lowing choices represent his medical beliefs EXCEPT the
a. use of high ethical standards of conduct.
b. important medical value of sorcery and witchcraft.
c. importance of closely monitoring a patient’s condition and recovery.
jl
d. value of diet and exercise and allowing nature to take its course in recovery.
jl jl jl
ANS: B
The Hippocratic Corpus is writings that they emphasize rational and natural explanations for
th e treatment of disease and reject sorcery and magic. The Hippocratic oath still governs the
ethi cal conduct of physicians today.
REF: p. 5
5. Throughout the historyof medicine, remarkable achievements have been recorded. These
e vents have led to our current understanding of the human organism and disease. As this
res earch continues, much of it will most likely focus on
a. proper sanitation and public health.
b. immunology and the development of vaccines.
c. germ theory and infection.
d. human genes and genetic engineering.
jl
ANS: D
Although the Human Genome Project is finished, analyses of the data will continue for
jl jl
many years. The replacement of faulty genes through gene therapy offers promises of cures
for a vari ety of hereditary diseases, and through genetic engineering, important
pharmaceuticals contin ue to be developed. Medical research will continue to focus on the
genetic code in all cells.

6. Wilhelm C. Roentgen’s discovery of ―the x-
ray‖ is regarded as one of medicine’s most significant achievements.Although his discovery
was accidental, his early research was so thorough that no significant findings have been
jl
add ed to his original theories. This in itself is a true tribute to the brilliance of Roentgen as
jl jl
a scie ntist. One of the most famous early images he created was an x-ray image of his
jl
a. colon.
b. laboratoryassistant’sfoot.
c. wife’s hand.
jl
d. kidneys.
ANS: C
November 8, 1895, is believed by historians to be the day that Roentgen created the famous
im age of the hand of his wife. Through his investigative methods, Roentgen identified the
proper ties of x-rays.
REF: p. 6
, 7. Avaluable x-ray procedure used to diagnose a myocardial infarction is
a. mammography.
b. myelography.
c. arthrography.
d. coronaryarteriography.
ANS: D
Coronary arteriography is an extremely valuable tool in diagnosing atherosclerosis, which can
jl
block the coronary arteries and cause a heart attack (myocardial infarction). By way of a
jl j jl
specia l catheter with a balloon tip, effective treatment of atherosclerosis is possible. This
treatment o f a blocked blood vessel is termed angioplasty. Angioplasty is used to treat
patients without ha ving to use invasive open-heart surgery. jl
REF: p. 8
8. All of the following are true of the diagnostic procedure of mammography EXCEPT
a. it is very valuable for the detection of early breast cancers.
jl
b. theprocedures may be performed using a general radiographic machine.
jl jl jl
c. radiographers need to be specially trained in order to perform mammography.
jl
d. radiographersmust be certified by the ARRT to qualify for the mammography
jl jl jl
ex amination.
ANS: B
Special breast imaging centers have been built to accommodate the demand for jl
mammography procedures. Equipment and supplies, such as a specially designed x-ray tube
jl jl
and high- resolution digital imaging detectors, are used to create high- jl
quality breast images. Mammography cannot be performed using general x-ray jl jl
equipment. REF: p. 8
9. To studythe blood vessels of the brain, kidneys, liver, and other organs, contrast material
is ad ministered into these vessels by using
a. catheters.
b. stents.
c. balloons.
d. none of the above.
ANS: A
Angiography is the term for radiologic examination of the blood vessels after injection of a
co ntrast medium. Most often, the contrast material is injected through a catheter, which can
be di rected to a variety of major arteries or veins for visualization of these structures.
REF: p. 8
10. Radiologic science continues to be one of the most exciting professions in medicine.An
jl jl
im aging modality that uses no ionizing radiation and the energy of radio waves and
jl jl
magneti c fields is
a. nuclear imaging.
b. thermography.
