d. magnetic resonance imaging. x x
ANS: B xx
Radiography is the making of records of internal structures of the body by passage of x-
x x x x x x x x x x x x x x x
rays or gamma rays through the body. These records or images are typically referred to as radio
x x x x x x x x x x x x x x x x
graphs.

2. Particular care must be taken when using radiation for medical imaging. This is the result of ra

diation’s ability to create x in human tissue and possible biochemical changes.
x x x x x x x x x
a. ionizations
b. radio waves x
c. sound waves x
d. thermal changes x
ANS: A xx
Some forms of electromagnetic energy, including x-
x x x x x x
rays, have the ability to ionize atoms in matter. These ionizations have the ability to disrupt the
x x x x x x x x x x x x x x x x x
composition of matter and are capable of disrupting life processes. Special protection should b
x x x x x x x x x x x x x
e provided to prevent excessive exposure to ionizing radiation.

3. In the diagnosis of patient disease states, physicians can select from an array of medical diagn
x x x x x x x x x x x x x x x
ostic modalities. A few of these involve the use of ionizing energy to create a medical image. If
x x x x x x x x x x x x x x x x x
xa physician is concerned about the use of ionizing radiation, he or she may choose to order any
x x x x x x x x x x x x x x x x x x
of the following diagnostic modalities EXCEPT
x x x x x
a. thermograms.
b. medical sonography. x
c. radiography.
d. magnetic resonance imaging. x x
ANS: C xx
Radiography involves the use of x- x x x x x
rays for the production of medical images. Medical procedures such as thermograms, sonogra
x x x x x x x x x x x x
ms, and magnetic resonance scans use nonionizing energy forms and consequently do not prod
x x x x x x x x x x x x x
uce ionizations in human tissue. They are regarded as nonionizing modalities for imaging and o
x x x x x x x x x x x x x x
ffer excellent 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 fol
x x x x x x x x x x x x x x x
lowing choices represent his medical beliefs EXCEPT the
x x x x x x x
a. use of high ethical standards of conduct.
x x x x x x
b. important medical value of sorcery and witchcraft. x x x x x x
c. importance of closely monitoring a patient’s condition and recovery. x x x x x x x x
d. value of diet and exercise and allowing nature to take its course in recovery.
x x x x x x x x x x x x x
ANS: B xx
The Hippocratic Corpus is writings that they emphasize rational and natural explanations for th
x x x x x x x x x x x x x
e treatment of disease and reject sorcery and magic. The Hippocratic oath still governs the ethic
x x x x x x x x x x x x x x x
al conduct of physicians today.

5. Throughout the history of medicine, remarkable achievements have been recorded. These e
x x x x x x x x x x x
vents have led to our current understanding of the human organism and disease. As this rese
x x x x x x x x x x x x x x x
arch continues, much of it will most likely focus on
x x x x x x x x x
a. proper sanitation and public health. x x x x
b. immunology and the development of vaccines. x x x x x
c. germ theory and infection. x x x
d. human genes and genetic engineering. x x x x
ANS: D xx
Although the Human Genome Project is finished, analyses of the data will continue for many y
x x x x x x x x x x x x x x x
ears. The replacement of faulty genes through gene therapy offers promises of cures for a variet
x x x x x x x x x x x x x x x
y of hereditary diseases, and through genetic engineering, important pharmaceuticals continue
x x x x x x x x x x
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- x x x x x x
ray‖ is regarded as one of medicine’s most significant achievements. Although his discovery
x x x x x x x x x x x x x
was accidental, his early research was so thorough that no significant findings have been adde
x x x x x x x x x x x x x x
d to his original theories. This in itself is a true tribute to the brilliance of Roentgen as a scienti
x x x x x x x x x x x x x x x x x x x
st. One of the most famous early images he created was an x-ray image of his
x x x x x x x x x x x x x x x
a. colon.
b. laboratory assistant’s foot. x x
c. wife’s hand. x
d. kidneys.
ANS: C xx
November 8, 1895, is believed by historians to be the day that Roentgen created the famous ima
x x x x x x x x x x x x x x x x
ge of the hand of his wife. Through his investigative methods, Roentgen identified the properti
x x x x x x x x x x x x x x
es of x-rays.

, 7. A valuable x-ray procedure used to diagnose a myocardial infarction is
x x x x x x x x x x
a. mammography.
b. myelography.
c. arthrography.
d. coronary arteriography. x
ANS: D xx
Coronary arteriography is an extremely valuable tool in diagnosing atherosclerosis, which can
x x x x x x x x x x x x
block the coronary arteries and cause a heart attack (myocardial infarction). By way of a special
x x x x x x x x x x x x x x x
catheter with a balloon tip, effective treatment of atherosclerosis is possible. This treatment of
x x x x x x x x x x x x x x x
a blocked blood vessel is termed angioplasty. Angioplasty is used to treat patients without havi
x x x x x x x x x x x x x x
ng to use invasive open-heart surgery.

8. All of the following are true of the diagnostic procedure of mammography EXCEPT
x x x x x x x x x x x x
a. it is very valuable for the detection of early breast cancers.
x x x x x x x x x x
b. the procedures may be performed using a general radiographic machine.
x x x x x x x x x
c. radiographers need to be specially trained in order to perform mammography. x x x x x x x x x x
d. radiographers must be certified by the ARRT to qualify for the mammography e x x x x x x x x x x x x
xamination.
ANS: B xx
Special breast imaging centers have been built to accommodate the demand for mammography
x x x x x x x x x x x x x
procedures. Equipment and supplies, such as a specially designed x-ray tube and high-
x x x x x x x x x x x x
resolution digital imaging detectors, are used to create high-
x x x x x x x x
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 ad
x x x x x x x x x x x x x x x x
ministered into these vessels by using x x x x x
a. catheters.
b. stents.
c. balloons.
d. none of the above. x x x
ANS: A xx
Angiography is the term for radiologic examination of the blood vessels after injection of a co
x x x x x x x x x x x x x x x
ntrast medium. Most often, the contrast material is injected through a catheter, which can be di
x x x x x x x x x x x x x x x
rected to a variety of major arteries or veins for visualization of these structures.

x x x x x x x x x x x x x x
aging modality that uses no ionizing radiation and the energy of radio waves and magnetic
x x x x x x x x x x x x x x
fields is
