The purpose of the rheostat in the x-ray circuitry is to:
a. minimize electron repulsion
b. monitor tube current
c. alter anode rotation speed
d. adjust filament temperature
d. adjust filament temperature
The rheostat adjusts filament temperature and is controlled by the
radiographer using the mA selector on the operator control panel.
An examination requisition states that the patient is blind. When providing
instructions for a chest radiograph, the technologist should:
a. speak loudly so the patient can hear
b. skip the explanation and try to complete the exam as quickly as possible
c. ask the patient how they would like to receive instructions
d. proceed with the examination, pantomiming instructions to the patient
c. ask the patient how they would like to receive instructions
A blind person might have specific instructions as to how to continue with
communication for an examination. The patient might suggest that the
technologist lead the way by offering a specific arm. People who are sight
impaired are not necessarily hearing impaired.
The recommended SID for a lateral projection of the C-spine is ______
inches.
a. 30
b. 40
c. 44 to 48
d. 60 to 72
d. 60 to 72
A 60- to 72-inch SID is needed to compensate for the increase OID that
occurs in a lateral position because of the space between the patient't
shoulder and neck. This increase in SID helps ensure visualization of all
seven cervical vertebrae.

The _____ measurement is an average calculated from the gonadal dose
received by the entire population; the measurement is used to determine the
effect of radiation exposure of future offspring.
a. relative biologic effectiveness
b. effective dose
c. genetically significant dose
d. lethal dose (LD) 50/30
c. genetically significant dose
Relative biologic effectiveness is used to compare biologic effectiveness of
radiations with different linear energy transfer (LET). Effective dose is the
equivalent dose multiplied by tissue-weighting factors. LD 50/30 is the
lethal dose that is required to kill 50% of the population in 30 days.
The kidneys are located in the:
a. peritoneal cavity
b. anteroperitoneum
c. supraperitoneum
d. retroperitoneum
d. retroperitoneum
Organs such as the pancreas and kidney lie behind the peritoneum
(retroperitoneum). The peritoneal cavity is the small space between the
visceral and parietal peritoneum and does not contain organs.
Anteroperitoneum means in front of the peritoneum.
Which projection of the chest is used to differentiate the lobes of the lungs,
demonstrate the interloper fissures, and localize pulmonary lesions?
a. PA
b. lateral
c. PA oblique
d. AP axial
b. lateral
A lateral projection is used to differentiate the lobes of the lungs,
demonstrate the interloper fissures, and localize pulmonary lesions. The left
lateral position best demonstrates left-sided pulmonary lesions, and the right
lateral position best demonstrates right-sided lesions
