ANS: B ll
Radiography is the making of records of internal structures of the body by passage of x- l l l l l l l l l l l l l l l
rays or gamma rays through the body. These records or images are typically referred to as radiogra
l l l l l l l l l l l l l l l l
phs.

2. Particular care must be taken when using radiation for medical imaging. This is the result of radiat
l l l l l l l l l l l l l l l l
ion’s ability to create l in human tissue and possible biochemical changes.l l l l l l l l l
a. ionizations
b. radio waves l
c. sound waves l
d. thermal changes l
ANS: A ll
Some forms of electromagnetic energy, including x-
l l l l l l
rays, have the ability to ionize atoms in matter. These ionizations have the ability to disrupt the co
l l l l l l l l l l l l l l l l l
mposition of matter and are capable of disrupting life processes. Special protection should be pro
l l l l l l l l l l l l l l
vided to prevent excessive exposure to ionizing radiation.

3. In the diagnosis of patient disease states, physicians can select from an array of medical diagnosti
l l l l l l l l l l l l l l l
c modalities. A few of these involve the use of ionizing energy to create a medical image. If a phys
l l l l l l l l l l l l l l l l l l l
ician is concerned about the use of ionizing radiation, he or she may choose to order any of the foll
l l l l l l l l l l l l l l l l l l l
owing diagnostic modalities EXCEPT l l l
a. thermograms.
b. medical sonography. l
c. radiography.
d. magnetic resonance imaging. l l
ANS: C ll
Radiography involves the use of x- l l l l l
rays for the production of medical images. Medical procedures such as thermograms, sonograms,
l l l l l l l l l l l l l
and magnetic resonance scans use nonionizing energy forms and consequently do not produce ion
l l l l l l l l l l l l l
izations in human tissue. They are regarded as nonionizing modalities for imaging and offer excell
l l l l l l l l l l l l l l
ent alternatives to physicians concerned about radiation exposure to patients.

4. The Greek physician Hippocrates is regarded as the father of Western medicine. All of the follo
l l l l l l l l l l l l l l l
wing choices represent his medical beliefs EXCEPT the
l l l l l l l
a. use of high ethical standards of conduct.
l l l l l l
b. important medical value of sorcery and witchcraft. l l l l l l
c. importance of closely monitoring a patient’s condition and recovery. l l l l l l l l
d. value of diet and exercise and allowing nature to take its course in recovery.
l l l l l l l l l l l l l
ANS: B ll
The Hippocratic Corpus is writings that they emphasize rational and natural explanations for the tr
l l l l l l l l l l l l l l
eatment of disease and reject sorcery and magic. The Hippocratic oath still governs the ethical con
l l l l l l l l l l l l l l l

l l l l l l l l l l l
nts have led to our current understanding of the human organism and disease. As this research c
l l l l l l l l l l l l l l l l
ontinues, much of it will most likely focus on l l l l l l l l
a. proper sanitation and public health. l l l l
b. immunology and the development of vaccines. l l l l l
c. germ theory and infection. l l l
d. human genes and genetic engineering. l l l l
ANS: D ll
Although the Human Genome Project is finished, analyses of the data will continue for many year
l l l l l l l l l l l l l l l
s. The replacement of faulty genes through gene therapy offers promises of cures for a variety of h
l l l l l l l l l l l l l l l l l
ereditary diseases, and through genetic engineering, important pharmaceuticals continue to be d
l l l l l l l l l l l
eveloped. Medical research will continue to focus on the genetic code in all cells.

6. Wilhelm C. Roentgen’s discovery of ―the x- l l l l l l
ray‖ is regarded as one of medicine’s most significant achievements. Although his discovery w
l l l l l l l l l l l l l
as accidental, his early research was so thorough that no significant findings have been added to
l l l l l l l l l l l l l l l l
his original theories. This in itself is a true tribute to the brilliance of Roentgen as a scientist. One
l l l l l l l l l l l l l l l l l l l
of the most famous early images he created was an x-ray image of his
l l l l l l l l l l l l l
a. colon.
b. laboratory assistant’s foot. l l
c. wife’s hand. l
d. kidneys.
ANS: C ll
November 8, 1895, is believed by historians to be the day that Roentgen created the famous image
l l l l l l l l l l l l l l l l l
of the hand of his wife. Through his investigative methods, Roentgen identified the properties of
l l l l l l l l l l l l l l l
x-rays.

, 7. Avaluable x-ray procedure used to diagnose a myocardial infarction is
l l l l l l l l l l
a. mammography.
b. myelography.
c. arthrography.
d. coronary arteriography. l
ANS: D ll
Coronary arteriography is an extremely valuable tool in diagnosing atherosclerosis, which can bl
l l l l l l l l l l l l
ock the coronary arteries and cause a heart attack (myocardial infarction). By way of a special cath
l l l l l l l l l l l l l l l l
eter with a balloon tip, effective treatment of atherosclerosis is possible. This treatment of a block
l l l l l l l l l l l l l l l
ed blood vessel is termed angioplasty. Angioplasty is used to treat patients without having to use i
l l l l l l l l l l l l l l l l
nvasive open-heart surgery. l l

8. All of the following are true of the diagnostic procedure of mammography EXCEPT
l l l l l l l l l l l l
a. it is very valuable for the detection of early breast cancers.
l l l l l l l l l l
b. the procedures may be performed using a general radiographic machine.
l l l l l l l l l
c. radiographers need to be specially trained in order to perform mammography. l l l l l l l l l l
d. radiographers must be certified by the ARRT to qualify for the mammography exa l l l l l l l l l l l l
mination.
ANS: B ll
Special breast imaging centers have been built to accommodate the demand for mammography pr
l l l l l l l l l l l l l
ocedures. Equipment and supplies, such as a specially designed x-ray tube and high-
l l l l l l l l l l l l
resolution digital imaging detectors, are used to create high- l l l l l l l l
quality breast images. Mammography cannot be performed using general x-ray equipment.

9. To study the blood vessels of the brain, kidneys, liver, and other organs, contrast material is admi
l l l l l l l l l l l l l l l l
nistered into these vessels by using l l l l l
a. catheters.
b. stents.
c. balloons.
d. none of the above. l l l
ANS: A ll
Angiography is the term for radiologic examination of the blood vessels after injection of a contr l l l l l l l l l l l l l l l
ast medium. Most often, the contrast material is injected through a catheter, which can be directe
l l l l l l l l l l l l l l l
