MULTIPLE CHOICE j




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


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




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


or gamma rays through the body. These records or images are typically referred t o a
j j j j j j j j j j j j j j j j


s radiographs.

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


radiation’s ability to create
j j j j


in human tissue and possible biochemical changes j j j j j j


.
a. ionizations
b. radio waves j


c. sound waves j


d. thermal changes j




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


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


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


i on should 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
j j j j j j j j j j j j j j


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


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


to order any of the following diagnostic modalities EXCEPT
j j j j j j j j j


a. thermograms.
b. medical sonography. j


c. radiography.
d. magnetic resonance imaging. j j




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


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


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


o not produce ionizations in human tissue. They are regarded as nonionizing modalities f or i
j j j j j j j j j j j j j j j


maging and offer excellent alternatives to physicians concerned about radiation expo sure t o
j j j j j j j j j j j j j j


patients.

4. The Greek physician Hippocrates is regarded as the father of Western medicine. All of t
j j j j j j j j j j j j j j


he following choices represent his medical beliefs EXCEPT the
j j j j j j j j j


a. use of high ethical standards of conduct. j j j j j j


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


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


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




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


f or the treatment of disease and reject sorcery and magic. The Hippocratic oath still gove r
j j j j j j j j j j j j j j j j j


jns the ethical conduct of physicians today.

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


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


jthis research continues, much of it will most likely focus on
j j j j j j j j j j


a. proper sanitation and public health. j j j j


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


c. germ theory and infection. j j j


d. human genes and genetic engineering. j j j j




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


years. The replacement of faulty genes through gene therapy offers promises of cure s
j j j j j j j j j j j j j j


for a variety of hereditary diseases, and through genetic engineering, important pharma
j j j j j j j j j j j j


ceuticals continue to be developed. Medical research will continue to focus on the
j j j j j j j j j j j j j


gene ti c code in all cells.

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


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


was accidental, his early research was so thorough that no significant findings have been
j j j j j j j j j j j j j j


added to his original theories. This in itself is a true tribute to the brilliance of Ro entgen as a
j j j j j j j j j j j j j j j j j j j j


scientist. One of the most famous early images he created was an x-
j j j j j j j j j j j j j


ray image of his j j j


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


c. wife’s hand. j


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


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


properties of x-rays.
