Radiation Protection In Medical Radiography (HESI
/ Registry Prep.) - Questions With Solutions
Which of the following increases radiation exposure to the patient and
potentially to the radiographer?
a. Production of optimal quality images with the first exposure.
b. Use of appropriate radiation protection procedures.
c. Repeated radiographic exposures as a result of technical error or
carelessness.
d. Limited radiographic examination, as ordered by the radiologist.
Correct Answer - c. Repeated radiographic exposures as a result of technical
error or carelessness.
To implement an effective radiation safety program in a facility that provides
imaging services, the employer must provide all of the following except :
a. The necessary resources and appropriate environment in which to execute
an ALARA program.
b. X-Ray equipment that can produce only very low kilovoltage and very high
milliamperage.
c. A written policy statement describing this ALARA program and identifying
the commitment of management to keeping all radiation exposure ALARA that
must be available to all employees in the workplace.
d. Perform periodic exposure audits to determine how radiation in the
workplace may be lowered. Correct Answer - b. X-Ray equipment that
can produce only very low kilovoltage and very high milliamperage.
Radiation has been present on Earth in all of its various manifestations since
the :
a. Beginning of time
b. Fourteenth century
c. Eighteenth century
d. Twentieth century Correct Answer - a. Beginning of time
, Both patient and imaging personnel radiation doses will remain well below
maximum allowable levels when :
a. Radiographers and radiologists keep exposure ALARA.
b. Referring physicians stop ordering imaging procedures.
c. Orders for imaging procedures are determined only by medical insurance
companies.
d. Patients assume sole responsibility for ordering their imaging procedures.
Correct Answer - a. Radiographers and radiologists keep exposure ALARA.
How can humans safely control the use of radiant energy?
1. By using the knowledge of radiation-induced hazards that has been gained
over many years.
2. By employing effective methods to limit or eliminate radiation-induced
hazards.
3. By completely eliminating the use of radiation in the healing arts.
a. 1 and 2 only
b. 1 and 3 only
c. 2 and 3 only
d. 1, 2, and 3 Correct Answer - a. 1 and 2 only
In medicine, when radiation safety principles are correctly applied during
imaging procedures, the energy deposited in living tissue by the radiation can
be limited, thereby :
a. Completely eliminating the possibility for reducing the potential for adverse
effects.
b. Not changing the possibility for reducing the potential for adverse effects.
c. Increasing the potential for adverse biologic effects.
d. Reducing the potential for adverse biologic effects. Correct Answer - d.
Reducing the potential for adverse biologic effects.
To reduce radiation exposure to the patient :
1. Reduce the amount of the x-ray "beam on" time.
2. Use as much distance as warranted between the x-ray tube and the patient
for the examination.
3. Use specific area shielding devices.
