CAMRT Flashcards
what does flexion/extension views of the c-spine assess?
anteroposterior mobility & anteroposterior movement, motility
what is the CR angle for a AP Coccyx?
10 degrees caudad, 10 degrees caudal CR angulation
What does ERCP stand for?
endoscopic retrograde cholangiopancreatography
why is ERCP done?
diagnose biliary & pancreatic pathologic condictions & investigate gallbladder, common bile duct and pancreatic ducts as well as intervention procedures
why is a ball catchers view done?
assist in detecting early radiologic changes needed to diagnose rheaumatoid arthritis
SC 35 the timer accuracy must be accurate to————–seconds or ————% of the setting which ever is greater
1/60 & 5mas
if a safelight test has become worse than the previous test, the thing to check first would be?
light streaks also bulb wattage,film type, timing etc
orthrostatic hypotension is?
low blood pressure due to standing upright (dizziness after getting up from a supine position)
is a germicide the same as a disinfectant?
germicide solution is a solution that destroys microrganisms and a disinfectant is any substance that inhibits the growth of bacteria. a disinfectant is a type of germicide
what is the difference between a Lauenstein view of the hip and a x-table lateral?
Lauenstein is the lesser trochanter in profile medially and the femoral neck superimposes the greater trochanter. x-table is the femoral neck demonstrated at about the same transverse level
what is the significance of Shenton’s Line?
used to evaluate pathology of the hip
the body part perpendicular to the CR when doing an intercondylar fossa is?
long axis of the leg, calf/lower leg/ tib-fib
purpose of lateral bending for scoliosis is?
compensatory curve will straighten/correct itself on one of these films. employed in patients with early scoliosis to determine the presence of structural change when bending to the right and left
optimal KVP for a chest x-ray and why?
100-130kvp to sufficiently penetrate the heart shadow and visualize the thoracic vertebrae as well as provide the long scale of contrast necessary to visualize lung details
how to adjust CR for a PCXR on a kyphotic patient
angle up slightly or leave the CR straight so the clavicles will be 1” below the apices of the lung
maximum size focal spot for a scaphoid
0.6mm
medication that may be added to the contrast to prevent a reaction
steroids and antihistamines(Benadryl, Medrol) may be used as a premedication but the contrast media should NEVER be mixed with medication
test tool used to test the focal spot is
standard a slit camera, pinhole camera & star pattern
nurse forgets to chart a medication during an IVP what should you do?
must bring 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
size of focal spot effects penumbra what does penumbra effect?
recorded detail
state the line focus principal
through angling the target, the effective area of the target is made much smaller than the actual area of electron interaction
the pedicles are sitting to far on the vertebral bodies so the patient is?
to far oblique (if oblique l-spine)
what is the purpose of a CVP line?
used for measuring central venous pressure and allowing nutrients and fluid to be instilled; best location would be the brachiocephalic vein at the junction of the SVC or actually within the SVC itself
what is the purpose and position of a Swan Ganz catheter?
Purpose- to measure wedge pressure, measure central venous pressure, measure systolic, diastolic and mean pressure, withdraw blood samples and to give fluid or inject drugs. Position- right or left pulmonary artery
