CAMRT (2025) ACTUAL EXAM comprehensive
questions and verified accurate solution (Detailed &
Elaborated)|get it 100% accurate!! 2025 TEST!!
What is the central ray for an AP axial coccyx? - ..(ANSWER)...Angle 10 degrees
caudad
What does ERCP stand for and what is it done for? - ..(ANSWER)...Endoscopic
Retrograde Cholangiopancreatography; used to diagnose biliary and pancreatic
pathologies when the biliary ducts are not dilated and no obstruction exists in the
ampulla
What do Flexion/Extension views of the Cervical Spine assess? - ..(ANSWER)...AP
motility of the cervical spine, or lack of movement due to trauma or disease
In SC35, what is the limit for light field and x-ray field alignment? -
..(ANSWER)...Must not exceed 2% of the SID
Why do we do a ball catcher's view? - ..(ANSWER)...Assist in detecting early
radiologic changes needed to diagnose rheumatoid arthritis
What is Orthostatic Hypotension? - ..(ANSWER)...Low blood pressure due to
standing upright (dizziness after getting up from a supine position)
What is the difference between Germicide and Disinfectant? -
..(ANSWER)...Germicide is a solution that destroys microorganisms; Disinfectant is
a type of germicide that inhibits the growth of bacteria
,2
Which carpal bone is most commonly fractured? - ..(ANSWER)...Scaphoid
What is the difference between Lauenstein and cross-table lateral views of the
hip? - ..(ANSWER)...Lauenstein=lesser trochanter in profile medially and femoral
neck superimposes greater trochanter
Cross-table Lateral=femoral neck demonstrated without overlap from greater
trochanter and a small amount of the lesser trochanter on the posterior surface
of the femur demonstrated in profile
Why do we include anterior soft tissue on a trauma cross-table lateral of the c-
spine? - ..(ANSWER)...Allows accurate measurement for any type of vertebral
displacement or noticeable swelling that could suggest a disguised fracture
When imaging the intercondylar fossa, which body part is perpendicular to the
central ray? - ..(ANSWER)...The long axis of the lower leg
What is the purpose of lateral bending for scoliosis imaging? -
..(ANSWER)...Employed in patients with early scoliosis to determine the presence
of structural change when bending to the right and left (compensatory curve will
correct itself on one of these images), as well predict or assess degree of
correction that can be obtained
,3
What is the optimal kV for a chest x-ray and why? - ..(ANSWER)...110-125 kV
sufficiently penetrates the heart shadow and visualizes the thoracic vertebrae as
well as provides the long scale of contrast necessary to visualize lung details
When doing a portable chest x-ray, how do you adjust the central ray for a
kyphotic patient? - ..(ANSWER)...Angle less (closer to perpendicular) slightly or
leave the tube perpendicular so clavicles will be 1" below apices of lung
Why is a CT study for PE scanned from from abdomen to just above shoulders? -
..(ANSWER)...To help reduce artifact of the contrast when the initial injection is
given because of the large amount of contrast that will be entering the superior
vena cava before the coronary arteries
What type of medication may be administered to a patient prior to a contrast
study to prevent a reaction? - ..(ANSWER)...Steroids and antihistamines (Benadryl,
Medrol)
What is Spatial Resolution? - ..(ANSWER)...The ability of an imaging process to
distinguish small, adjacent, high-contrast structures in the object
What should you do if a nurse forgets to chart a medication during an Intravenous
pyelogram (IVP)? - ..(ANSWER)...Bring any omissions to their attention - any item
that has not been documented on the chart is
considered to be "not performed" in a court of law
What does penumbra effect? - ..(ANSWER)...Recorded detail
, 4
What is the Line Focus Principle? - ..(ANSWER)...Through angling the target, the
effective area of the target is made much smaller than the actual area of electron
interaction (smaller anode angle=smaller effective focal spot, larger anode
angle=larger effective focal spot)
How do you know if an oblique image of the L-spine is over-rotated? -
..(ANSWER)...The pedicles sit too far posterior on vertebral bodies (Remember:
***PP, too much***=posterior pedicles)
What is a PICC line? What is its position and purpose? - ..(ANSWER)...Peripherally
Inserted Central Catheter; placed in brachiocephalic vein at the junction of the
SVC or actually within the SVC itself; used for measuring central venous pressure
as well as allowing nutrients and fluid to be instilled
What is the position and purpose of a Swan-Ganz catheter? - ..(ANSWER)...Placed
in right or left pulmonary artery; used to measure wedge pressure, central venous
pressure, systolic, diastolic, and mean pressure, to withdraw blood samples, and
to inject drugs or administer fluids
What are the three layers of mater surrounding the brain? - ..(ANSWER)...From
outer to inner: Dura, Arachnoid, and Pia
What is the appearance of a subdural hematoma on a CT (acute and chronic) and
the likely cause of one? - ..(ANSWER)...Acute subdural hematoma will have a
crescent-shaped peripheral high-density lesion; Chronic
