,MULTIPLE CHOICE o




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


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




ANS: B o o


Radiography is the making of records of internal structures of the body by passage of x-rays
o o o o o o o o o o o o o o o


or gamma rays through the body. These records or images are typically referred to as
o o o o o o o o o o o o o o o


radiographs.

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


oradiation’s ability to create in human tissue and possible biochemical changes.
o o o o o o o o o o


a. ionizations
b. radio waves o


c. sound waves o


d. thermal changes o




ANS: A o o


Some forms of electromagnetic energy, including x-rays, have the ability to ionize atoms in
o o o o o o o o o o o o o


matter. These ionizations have the ability to disrupt the composition of matter and are
o o o o o o o o o o o o o o


capable of disrupting life processes. Special protection should be provided to prevent
o o o o o o o o o o o o


excessive exposure to ionizing radiation.

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


odiagnostic modalities. A few of these involve the use of ionizing energy to create a medical
o o o o o o o o o o o o o o o


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


oto order any of the following diagnostic modalities EXCEPT
o o o o o o o o


a. thermograms.
b. medical sonography. o


c. radiography.
d. magnetic resonance imaging. o o




ANS: C o o


Radiography involves the use of x-rays for the production of medical images. Medical
o o o o o o o o o o o o


procedures such as thermograms, sonograms, and magnetic resonance scans use nonionizing
o o o o o o o o o o o


energy forms and consequently do not produce ionizations in human tissue. They are
o o o o o o o o o o o o o


regarded as nonionizing modalities for imaging and offer excellent alternatives to physicians
o o o o o o o o o o o o


concerned about radiation exposure to patients.

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


ofollowing choices represent his medical beliefs EXCEPT the
o o o o o o o


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


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


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


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




ANS: B o o


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


the treatment of disease and reject sorcery and magic. The Hippocratic oath still governs the
o o o o o o o o o o o o o o o


ethical conduct of physicians today.

5. Throughout the history of medicine, remarkable achievements have been recorded. These
o o o o o o o o o o


oevents have led to our current understanding of the human organism and disease. As this
o o o o o o o o o o o o o o


oresearch continues, much of it will most likely focus on
o o o o o o o o o


a. proper sanitation and public health. o o o o


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


c. germ theory and infection. o o o


d. human genes and genetic engineering. o o o o




ANS: D o o


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


many years. The replacement of faulty genes through gene therapy offers promises of cures
o o o o o o o o o o o o o o


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


pharmaceuticals continue to be developed. Medical research will continue to focus on the
o o o o o o o o o o o o o


genetic code in all cells.

6. Wilhelm C. Roentgen’s discovery of “the x-ray” is regarded as one of medicine’s most
o o o o o o o o o o o o o


osignificant achievements. Although his discovery was accidental, his early research was so
o o o o o o o o o o o


othorough that no significant findings have been added to his original theories. This in itself
o o o o o o o o o o o o o o


ois a true tribute to the brilliance of Roentgen as a scientist. One of the most famous early
o o o o o o o o o o o o o o o o o


oimages he created was an x-ray image of his
o o o o o o o o


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


c. wife’s hand. o


d. kidneys.
ANS: C o o


November 8, 1895, is believed by historians to be the day that Roentgen created the famous
o o o o o o o o o o o o o o o


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


properties of x-rays.

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


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




ANS: D o o


Coronary arteriography is an extremely valuable tool in diagnosing atherosclerosis, which
o o o o o o o o o o


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


special catheter with a balloon tip, effective treatment of atherosclerosis is possible. This
o o o o o o o o o o o o o


treatment of a blocked blood vessel is termed angioplasty. Angioplasty is used to treat
o o o o o o o o o o o o o o


patients without having to use invasive open-heart surgery.

8. All of the following are true of the diagnostic procedure of mammography EXCEPT
o o o o o o o o o o o o


a. it is very valuable for the detection of early breast cancers.
o o o o o o o o o o


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


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


d. radiographers must be certified by the ARRT to qualify for the mammography o o o o o o o o o o o


examination.
o




ANS: B o o


Special breast imaging centers have been built to accommodate the demand for
o o o o o o o o o o o


mammography procedures. Equipment and supplies, such as a specially designed x-ray tube
o o o o o o o o o o o o


and high-resolution digital imaging detectors, are used to create high-quality breast images.
o o o o o o o o o o o o


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
o o o o o o o o o o o o o o o


oadministered into these vessels by using o o o o o


a. catheters.
b. stents.
c. balloons.
d. none of the above. o o o




ANS: A o o


Angiography is the term for radiologic examination of the blood vessels after injection of a
o o o o o o o o o o o o o o


contrast medium. Most often, the contrast material is injected through a catheter, which can
o o o o o o o o o o o o o o


be directed to a variety of major arteries or veins for visualization of these structures.

10. Radiologic science continues to be one of the most exciting professions in medicine. An
o o o o o o o o o o o o o


oimaging modality that uses no ionizing radiation and the energy of radio waves and
o o o o o o o o o o o o o


omagnetic fields is o o


a. nuclear imaging. o


b. thermography.
c. CVIT.
