MULTIPLE CHOICE
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 ra
diographs.
4
2. Particular care must be taken when using radiation for medical imaging. This is the result of
radiation’s ability to create in human tissue and possible biochemical changes.
a. ionizations
b. radio waves
c. sound waves
d. thermal changes
ANS: A
Some forms of electromagnetic energy, including x-
rays, have the ability to ionize atoms in matter. These ionizations have the ability to disrupt t
he composition of matter and are capable of disrupting life processes. Special protection sh
ould be provided to prevent excessive exposure to ionizing radiation.

3. In the diagnosis of patient disease states, physicians can select from an array of medical dia
gnostic modalities. A few of these involve the use of ionizing energy to create a medical im
l8
age. If a physician is concerned about the use of ionizing radiation, he or she may choose to
order any of the following diagnostic modalities EXCEPT
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, sonogr
ams, and magnetic resonance scans use nonionizing energy forms and consequently do not p
roduce ionizations in human tissue. They are regarded as nonionizing modalities for imaging
and offer excellent alternatives to physicians concerned about radiation exposure to patients
.
, REF: pp. 3-4
4. The Greek physician Hippocrates is regarded as the father of Western medicine. All of the
following 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.
d. value of diet and exercise and allowing nature to take its course in recovery.
ANS: B
The Hippocratic Corpus is writings that they emphasize rational and natural explanations for
the treatment of disease and reject sorcery and magic. The Hippocratic oath still governs the
l8
ethical conduct of physicians today.

5. Throughout the history of medicine, remarkable achievements have been recorded. These
events have led to our current understanding of the human organism and disease. As this
l8
research 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.
ANS: D
Although the Human Genome Project is finished, analyses of the data will continue for ma
ny years. The replacement of faulty genes through gene therapy offers promises of cures for
a variety of hereditary diseases, and through genetic engineering, important pharmaceutical
s continue to be developed. Medical research will continue to focus on the genetic code in a
ll cells.

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