MULTIPLE CHOICE g




1. The use of x-rays to create a medical image on patients is referred to as
g g g g g g g g g g g g g g


a. electrocardiography.
b. radiography.
c. sonography.
d. magnetic resonance imaging. g g




ANS: B
Radiography is the making of records of internal structures of the body by passage of x-
g g g g g g g g g g g g g g g


rays or gamma rays through the body. These records or images are typically
g g g g g g g g g g g g g


referred t o a s radiographs.

REF: p. 4 g




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


of radiation’s ability to create
g g g g g


in human tissue and possible biochemical changes g g g g g g


.
a. ionizations
b. radio waves g


c. sound waves g


d. thermal changes g




ANS: A
Some forms of electromagnetic energy, including x-
g g g g g g


rays, have the ability to ionize atoms in matter. These ionizations have the ability to disru
g g g g g g g g g g g g g g g


pt the composition of matter and are capable of disrupting life processes. Special

3. In the diagnosis of patient disease states, physicians can select from an array of medical
g g g g g g g g g g g g g g


diagnostic modalities. A few of these involve the use of ionizing energy to create a medi
g g g g g g g g g g g g g g g g


cal image. If a physician is concerned about the use of ionizing radiation, he or she may
g g g g g g g g g g g g g g g g g


choose to order any of the following diagnostic modalities EXCEPT
g g g g g g g g g g


a. thermograms.
b. medical sonography. g


c. radiography.
d. magnetic resonance imaging. g g




ANS: C
Radiography involves the use of x- g g g g g


rays for the production of medical images. Medical procedures such as thermograms, son
g g g g g g g g g g g g


o grams, and magnetic resonance scans use nonionizing energy forms and consequently d
g g g g g g g g g g g g


o not produce ionizations in human tissue. They are regarded as nonionizing modalities f
g g g g g g g g g g g g g


or i maging and offer excellent alternatives to physicians concerned about radiation expo
g g g g g g g g g g g g g


sure t o patients.

g g g g g g


b. important medical value of sorcery and witchcraft. g g g g g g


c. importance of closely monitoring a patient’s condition and recovery. g g g g g g g g


d. value of diet and exercise and allowing nature to take its course in recovery.
g g g g g g g g g g g g g




ANS: B
The Hippocratic Corpus is writings that they emphasize rational and natural
g g g g g g g g g g


explanations f or the treatment of disease and reject sorcery and magic. The Hippocratic
g g g g g g g g g g g g g g


oath still gove r ns the ethical conduct of physicians today.

5. Throughout the history of medicine, remarkable achievements have been recorded. The
g g g g g g g g g g


gs e events have led to our current understanding of the human organism and disease. A
g g g g g g g g g g g g g g g


g s this research continues, much of it will most likely focus on
g g g g g g g g g g g


a. proper sanitation and public health. g g g g


b. immunology and the development of vaccines. g g g g g


c. germ theory and infection. g g g


d. human genes and genetic engineering. g g g g




ANS: D
Although the Human Genome Project is finished, analyses of the data will continue for m
g g g g g g g g g g g g g g


any years. The replacement of faulty genes through gene therapy offers promises of
g g g g g g g g g g g g g


cure s for a variety of hereditary diseases, and through genetic engineering, important
g g g g g g g g g g g g g


pharma ceuticals continue to be developed. Medical research will continue to focus
g g g g g g g g g g g g


on the gene ti c code in all cells.

6. Wilhelm C. Roentgen’s discovery of ―the x- g g g g g g


ray‖ is regarded as one of medicine’s most significant achievements. Although his disco
g g g g g g g g g g g g


gvery was accidental, his early research was so thorough that no significant findings have
g g g g g g g g g g g g g


gbeen added to his original theories. This in itself is a true tribute to the brilliance of Ro
g g g g g g g g g g g g g g g g g


gentgen as a scientist. One of the most famous early images he created was an
g g g g g g g g g g g g g g


gx-
ray image of his
g g g


a. colon.
b. laboratory assistant’s foot. g g


c. wife’s hand. g


d. kidneys.
ANS: C
November 8, 1895, is believed by historians to be the day that Roentgen created the famo
g g g g g g g g g g g g g g g


us image of the hand of his wife. Through his investigative methods, Roentgen identified
g g g g g g g g g g g g g g


the properties of x-rays.

, 7. A valuable x-ray procedure used to diagnose a myocardial infarction is
g g g g g g g g g g


a. mammography.
b. myelography.
c. arthrography.
d. coronary arteriography. g




ANS: D
Coronary arteriography is an extremely valuable tool in diagnosing atherosclerosis, which
g g g g g g g g g g


can block the coronary arteries and cause a heart attack (myocardial infarction). By
g g g g g g g g g g g g g


way o f a special catheter with a balloon tip, effective treatment of atherosclerosis is
g g g g g g g g g g g g g g g


possible. T his treatment of a blocked blood vessel is termed angioplasty. Angioplasty is
g g g g g g g g g g g g g g


used to tr eat patients without having to use invasive open-heart surgery.

b. the procedures may be performed using a general radiographic machine.
g g g g g g g g g


c. radiographers need to be specially trained in order to perform mammography. g g g g g g g g g g


d. radiographers must be certified by the ARRT to qualify for the mammograp g g g g g g g g g g g


h y examination.
g g g




ANS: B
Special breast imaging centers have been built to accommodate the demand for mammogr
g g g g g g g g g g g g


aphy procedures. Equipment and supplies, such as a specially designed x-
g g g g g g g g g g g


ray tube and high- resolution digital imaging detectors, are used to create high-
g g g g g g g g g g g g


quality breast images. Mammography cannot be performed using general x-

b. stents.
c. balloons.
d. none of the above. g g g




ANS: A
Angiography is the term for radiologic examination of the blood vessels after g g g g g g g g g g g


injection o f a contrast medium. Most often, the contrast material is injected through a
g g g g g g g g g g g g g g g


catheter, w hic h can be directed to a variety of major arteries or veins for visualization
g g g g g g g g g g g g g g g g g


of these stru ctu res.
