ARRT - ANSWER American Registry of Radiologic Technologists
ASRT - ANSWER American Society of Radiologic Technologists
What do the ASRT and ARRT do for the radiologic technology profession - ANSWER The ASRT wrote and
maintains the Radiography Practice Standards. They define the practice of radiography, describe
necessary education and certification, and include the Radiographer Scope of Practice. In addition, the
practice standards include Clinical Performance Standards, Quality Performance Standards, and
Professional Performance Standards.
The American Registry of Radiologic Technologists (ARRT) created and maintains the Standards of Ethics
that apply to all radiologic technologists who are certified by the organization.
How often should the radiographic table be cleaned? - ANSWER The radiographic table should be
cleaned after each patient.
How do members of the radiologic technology profession help to control pathogen contamination? -
ANSWER By following Standard Precautions and Transmission-based precautions

_________ the sheet - ANSWER Under
What protective apparel should radiographers wear if the possibility of touching blood exists? - ANSWER
Disposable gloves
What procedure should be followed to dispose of used hypodermic needles properly? - ANSWER Place

List procedures that require aseptic technique when performed in the radiology department. - ANSWER
Cystography, intravenous urography, spinal puncture, arthrography, angiography
True or false. When performing an examination in the operating room (OR), position the C-arm next to
the operating table on the same side as the surgeon - ANSWER False, to the side opposite of surgeon
Before beginning a radiographic examination, what should the radiographer do to gain the cooperation
of a coherent patient? - ANSWER Give an explanation of the procedure to be performed.
What is the minimum number of personnel that should be used to transfer a helpless patient from a
gurney to the radiographic table? - ANSWER Four
When the radiologist is unable to see the patient, who is responsible for ensuring that an adequate
clinical history accompanies the radiographs? - ANSWER Radiographer
What is the role of the radiographer in interpretation of radiographic images? How should requests for
interpretations be handled? - ANSWER Interpretation of images is outside of the scope of practice for
radiographers. Requests for interpretations must be referred to a qualified physician, such as a
radiologist.
List the three ways a patient's colon may be cleansed for an abdominal examination. - ANSWER Limited
diet, laxatives, and enemas
,True or false. If washable gowns are used, they should be starched; starch is radiolucent, which means it
can be penetrated easily by x-rays. - ANSWER False, starch is radiopaque
Why is it necessary to ensure that any folds in cloth gowns are straightened out before making the
radiographic exposure? - ANSWER To prevent confusing shadows (artifacts)
What devices must be removed from the patient within the area of interest when the skull is examined?
- ANSWER Dentures, removable bridgework, earrings, necklaces, hairpins, and eyeglasses
Identify the three types of muscular tissue and state the type of motion (voluntary or involuntary)
associated with each. - ANSWER Smooth, involuntary (peristalsis); cardiac, involuntary (systole); and
striated, voluntary
The rhythmic motion of smooth muscle structures is called _________________________. - ANSWER
Peristalsis
What exposure factor is used to control involuntary motion? - ANSWER Exposure time
What body system controls the movement of voluntary muscles? - ANSWER Central nervous system
From the following list, circle the four ways voluntary motion can be controlled by a radiographer.
a. Increase mAs
b. Decrease mAs
c. Apply immobilization
d. Give clear instructions
e. Adjust support devices
f. Increase exposure time
g. Decrease exposure time
h. Provide patient comfort - ANSWER c, d, e, g
, True of False. Most exams require the patient to hold their breath at some phase of respiration, such as
the end of inhalation or exhalation - ANSWER True
Define image receptor (IR) - ANSWER A device that receives the energy of the x-ray beam and forms the
image of the body part
List two purposes of collimation when restricted to irradiate only the anatomy of interest. - ANSWER
First, it minimizes the amount of radiation to the patient by restricting exposure to essential anatomy
only. Second, it reduces the amount of scatter radiation that can reach the IR, which reduces the
potential for a reduction in contrast resolution.
True or false. Creating an image using a larger than required (necessary) field size is a violation of the
ARRT Code of Ethics. - ANSWER True
True or false. Shuttering of direct digital images is an acceptable substitution for proper collimation. -
ANSWER False. Shuttering gives only the displayed image the appearance of proper collimation and does
not protect the patient from unnecessary radiation exposure. The use of shuttering in place of proper
collimation is a violation of the ARRT Code of Ethics and a potential legal liability
From the following list, indicate which of the following isnot recommended or unacceptable for right and
left side marker placement.
a. Use of electronic insertion of the side marker in digital imaging
b. Placement of the marker in the anatomy of interest
c. Placement of the marker on the border of the collimated field
d. Placing the marker directly on the body part - ANSWER a, b, d
Define and describe the anatomic position. - ANSWER Refers to a position in which the patient is
standing erect with the face and eyes directed forward, arms extended by the sides with the palms of
the hands facing forward, heels together, and toes pointing anteriorly
Describe how a posteroanterior (PA) projection radiograph of the chest should be oriented on the display
monitor. - ANSWER Radiographs are usually oriented on the display monitor so that the person looking
at the image sees the body part as though viewed facing the patient.
