2026/2027
1. What does flexion/extension views of c-spine assess? - correct answer-a.
Anteroposterior mobility (RAD CRITIQUE)
b. Anteroposterior movement, motility (MERRILLS)
What is the CR angle for an AP coccyx? - correct answer-a. 10 degrees caudad
(MERRILLS)
b. 10 degree caudal central ray angulation (RAD CRITIQUE)
3. What does ERCP stand for and why is it done? - correct answer-a. Diagnose
biliary and pancreatic pathologic conditions (MERRILLS)
b. Used to investigate gallbladder, common bile duct and pancreatic ducts as well
as intervention (PATH & PROCEDURES YR 1)
4. SC 20 (p24) timer accuracy must be accurate to ______second or _____% of
the setting which ever is greater. - correct answer-1/60 and 7 %
5. Why is a ball catchers view done? - correct answer-a. Assist in detecting early
radiologic changes needed to diagnose rheumatoid arthritis (MERRILLS)
,6. A safelight test has become worst than the previous test what would you check
first? - correct answer-a. Light leaks (STEVENS) - also: bulb wattage, film type,
timing, etc.
7. What is orthostatic hypotension? - correct answer-a. Low blood pressure due
to standing upright (dizziness after getting up from a supine position) (MEDICAL
DICTIONARY)
8. Is a germicide the same as a disinfectant? - correct answer-a. A germicide is a
solution that destroys microorganisms
b. A disinfectant is any substance that inhibits the growth of bacteria
c. A disinfectant is a type of germicide (TORRES)
9. Difference between a lauenstein view of hip and x-table lateral - correct
answer-a. Lauenstein = lesser trochanter in profile medially and femoral neck
superimposes greater trochanter
b. X-table = femoral neck demoed without any foreshortening, greater and lesser
trochanters are demoed at about the same transverse level (RAD CRITIQUE,
MERRILLS)
10. The significance of shenton's line. - correct answer-a. Used to evaluate
pathology of the hip (PATH & PROCEDURES 1)
11. What body part is perpendicular to the CR when doing an intercondylar fossa?
- correct answer-a. Long axis of the leg (MERRILLS)
b. Calf / lower leg / tib-fib
,12. Purpose of lateral bending for scoliosis. - correct answer-a. Compensatory
curve will straighten / correct itself on one of these films (PATH & PROCEDURES 2)
b. Employed in patients with early scoliosis to determine the presence of
structural change when bending to the right and left (MERRILLS)
13. What is the optimal kVp for a chest x-ray and why? - correct answer-a. 100-
130 kVp sufficiently penetrates the heart shadow and visualizes the thoracic
vertebrae as well as provides the long scale of contrast necessary to visualizr lung
details (RAD CRITIQUE)
14. When x-raying a kyphotic patient for portable chest x-ray how do you adjust
your CR? - correct answer-a. Angle up slightly or leave the CR straight so clavicles
will be 1" below apices of lung (CLINICAL)
15. Maximum size focal spot for scaphoid. - correct answer-a. 0.6 mm (CLINICAL)
16. What medication may be added to the contrast before injection to prevent a
reaction? - correct answer-a. Steroids and antihistamines (Benadryl, Medrol) may
be used as a premedication but contrast media shoul NEVER be mixed with
medication (TORTORICI, TORRES)
17. Test tool used to test focal spot. - correct answer-a. Standard = slit camera;
also pinhole camera + star pattern (BUSHONG)
18. You notice the nurse forgets to chart that a medication was given while the
patient was having an IVP what should you do? - correct answer-a. Must 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 (TORRES)
, 19. The size of focal spot effects penumbra, what does penumbra effect? - correct
answer-a. Recorded detail (CARLTON & ADLER)
20. State the line focus principle. - correct answer-a. Through angling the target,
the effective area of the target is made much smaller than the actual area of
electron interaction (BUSHONG)
21. The pedicles sit too posterior on vertebral bodies, so the patient is_________.
- correct answer-too far obliqued
(if an oblique L-spine)
22. Purpose and position of a CVP line. - correct answer-a. Used for measuring
central venous pressure as well as allowing nutrients and fluid to be instilled; best
location would be brachiocephalic vein at the junction of the SVC or actually
within the SVC itself (TORRES)
23. Purpose and position of a swan ganz catheter. - correct answer-a. Purpose =
1. to measure wedge pressure
2. to measure central venous pressure
3. to measure systolic, diastolic and mean pressure
4. to withdraw blood samples
5. to give fluid or inject drugs
Location = right or left pulmonary artery
24. What does plia circularis mean? - correct answer-a. The numerous folds of the
mucous membrane of the small intestine, running transversely for about two-
thirds of the circumference of the gut (MEDICAL DICTIONARY)
