1.
A patient arrives in the radiology department for an examination of the
chest because of persistent cough, fever, and shortness of breath. Before
positioning the patient, the technologist reviews the requisition and
confirms the patient's identity using two identifiers. The patient states
that she could possibly be pregnant but is unsure because her menstrual
period is several days late. What is the most appropriate initial action by
the technologist?
A. Proceed with the examination because chest radiography does not
expose the abdomen directly
B. Ask the patient to sign a pregnancy waiver and immediately
perform the examination
C. Follow department policy for pregnancy screening and notify the
appropriate provider before proceeding when required
D. Cancel the examination permanently because radiographic
procedures are contraindicated during pregnancy
Correct answer: C

During a routine radiographic examination, a technologist notices that
the image receptor is not properly aligned with the anatomy of interest.
The patient has already been positioned and is uncomfortable. The
technologist wants to obtain the diagnostic image while minimizing the
possibility of repeating the exposure. Which principle should guide the
technologist's decision?
A. Increase the exposure time substantially
B. Correct the positioning and alignment before making the exposure
C. Increase the source-to-image distance without repositioning
D. Collimate only after the exposure has been completed
Correct answer: B
3.
A patient is scheduled for a chest radiograph and is unable to stand
because of severe weakness. The physician still requires an upright-type
assessment of the lungs and pleural spaces. Which alternative
positioning method is most appropriate when the patient cannot stand
but can sit upright?
A. Supine AP chest
B. Sitting AP chest
C. Prone abdominal examination
D. Lateral decubitus abdomen
Correct answer: B
4.
A technologist is preparing to perform a portable radiographic
examination on a patient in an isolation room. The patient has a
contagious respiratory infection, and several pieces of portable
,3
equipment must be taken into the room. Which action best demonstrates
appropriate infection-control practice?
A. Bring all equipment into the room and clean it at the end of the shift
B. Use appropriate personal protective equipment and disinfect
equipment according to facility protocol before removing it
C. Avoid hand hygiene because gloves will provide complete protection
D. Remove the patient's isolation sign before beginning the
examination
Correct answer: B
5.
A patient undergoing radiography asks why the technologist is standing
behind a protective barrier during the exposure. The patient says that the
technologist should remain next to the patient because otherwise the
image might not be produced correctly. Which explanation is most
appropriate?
A. The technologist receives no radiation from an X-ray tube B.
Radiation protection principles require personnel to maximize
distance and use shielding when appropriate
C. Protective barriers are used only when the patient has an infectious
disease
D. The barrier prevents scatter radiation from reaching the image
receptor
Correct answer: B
6.
A radiographic examination requires the technologist to select technical
factors that will produce adequate image quality while keeping radiation
, 4
exposure as low as reasonably achievable. Which principle is most
directly associated with minimizing unnecessary radiation exposure?
A. ALARA
B. SID
C. OID
D. AEC
Correct answer: A
7.
A patient presents for an abdominal radiograph with a requisition
indicating severe abdominal pain and possible bowel obstruction. The
patient is unable to stand safely. Which positioning consideration is
particularly important when evaluating for air-fluid levels?
A. An erect or decubitus position may be useful when clinically
appropriate
B. Only a prone position can demonstrate air-fluid levels
C. A lateral wrist projection should be performed first
D. The patient must always be placed in a Trendelenburg position
Correct answer: A
8.
During a radiographic examination, the technologist observes that the
patient's clothing contains a metal zipper directly over the anatomy
being examined. What should the technologist do?
A. Leave the zipper in place because metallic objects never affect
radiographic images
B. Remove or reposition the metallic object when possible before
exposure
