MULTIPLE CHOICE cm




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


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




ANS: B cmcm


Radiography is the making of records of internal structures of the body by passage of x
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


-
rays or gamma rays through the body. These records or images are typically referred to
cm cm cm cm cm cm cm cm cm cm cm cm cm cm


cmas radiographs.

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


ult of radiation’s ability to create
cm cm cm cm cm cm


in human tissue and possible biochemical chang cm cm cm cm cm cm


es.
a. ionizations
b. radio waves cm


c. sound waves cm


d. thermal changes cm




ANS: A cmcm


Some forms of electromagnetic energy, including x-
cm cm cm cm cm cm


rays, have the ability to ionize atoms in matter. These ionizations have the ability to di
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


srupt the composition of matter and are capable of disrupting life processes. Special pr
cm cm cm cm cm cm cm cm cm cm cm cm cm


otection 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 medic
cm cm cm cm cm cm cm cm cm cm cm cm cm cm


al diagnostic modalities. A few of these involve the use of ionizing energy to create a
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


medical image. If a physician is concerned about the use of ionizing radiation, he or sh
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


e may choose to order any of the following diagnostic modalities EXCEPT
cm cm cm cm cm cm cm cm cm cm cm


a. thermograms.
b. medical sonography. cm


c. radiography.
d. magnetic resonance imaging. cm cm




ANS: C cmcm


Radiography involves the use of x- cm cm cm cm cm


rays for the production of medical images. Medical procedures such as thermograms, so
cm cm cm cm cm cm cm cm cm cm cm cm


nograms, and magnetic resonance scans use nonionizing energy forms and consequently
cm cm cm cm cm cm cm cm cm cm cm


do not produce ionizations in human tissue. They are regarded as nonionizing modalitie
cm cm cm cm cm cm cm cm cm cm cm cm


s for imaging and offer excellent alternatives to physicians concerned about radiation ex

4. The Greek physician Hippocrates is regarded as the father of Western medicine. All o
cm cm cm cm cm cm cm cm cm cm cm cm cm


f the following choices represent his medical beliefs EXCEPT the
cm cm cm cm cm cm cm cm cm


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


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


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


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




ANS: B cmcm


The Hippocratic Corpus is writings that they emphasize rational and natural explanations
cm cm cm cm cm cm cm cm cm cm cm


for the treatment of disease and reject sorcery and magic. The Hippocratic oath still g
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


overns the ethical conduct of physicians today.

ese events have led to our current understanding of the human organism and disease
cm cm cm cm cm cm cm cm cm cm cm cm cm


. As this research continues, much of it will most likely focus on
cm cm cm cm cm cm cm cm cm cm cm cm


a. proper sanitation and public health.

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


c. germ theory and infection. cm cm cm


d. human genes and genetic engineering.
cm cm cm cm




ANS: D cmcm


Although the Human Genome Project is finished, analyses of the data will continue for
cm cm cm cm cm cm cm cm cm cm cm cm cm


many years. The replacement of faulty genes through gene therapy offers promises of c
cm cm cm cm cm cm cm cm cm cm cm cm cm cm


ures for a variety of hereditary diseases, and through genetic engineering, important ph

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


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


covery was accidental, his early research was so thorough that no significant findings
cm cm cm cm cm cm cm cm cm cm cm cm cm


have been added to his original theories. This in itself is a true tribute to the brillianc
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


e of Roentgen as a scientist. One of the most famous early images he created was an
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


cmx-ray image of his cm cm cm


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


c. wife’s hand. cm


d. kidneys.
ANS: C cmcm


November 8, 1895, is believed by historians to be the day that Roentgen created the fa
cm cm cm cm cm cm cm cm cm cm cm cm cm cm cm


mous image of the hand of his wife. Through his investigative methods, Roentgen iden
cm cm cm cm cm cm cm cm cm cm cm cm cm


tified the properties of x-rays.
