x ray clinical exam ACTUAL QUESTIONS
AND CORRECT ANSWERS
how do you calculate mAs - CORRECT ANSWERS✅✅mA x time (secs) = mAs
how do we calculate kVp? - CORRECT ANSWERS✅✅santes rule (2 x thickness) + 40
list common PPE - CORRECT ANSWERS✅✅lead apron, gloves, dosimeter badge and
thyroid shield, glasses
what is the measure of mA - CORRECT ANSWERS✅✅measure of milliamperage quantity
of x rays required for a given exposure
why might you get geometric distortion? - CORRECT ANSWERS✅✅motion, improper
storage, large focal spot size and decreased subjuct image distance
why might you get fog? - CORRECT ANSWERS✅✅timming issues, light leaks, film
processing was not done well
why might you get artifacts? - CORRECT ANSWERS✅✅wrong film-screen combo
machine timer is out of calibration
SID is incorrect
over/under exposed
how do you store a cassette? - CORRECT ANSWERS✅✅in a dark room , in a upright
vertical posistion
low temp around 50-70 degrees
and you want low humidity around 30 - 50%
away from chemical and xray machine
what do you log in the book at tmcc? - CORRECT ANSWERS✅✅the date, patients name/id
number, the mAs and kvp levels used, the region you are radiographing, the measurements of
,that region and a description of the animal as well as the name of the person who is doing the
x ray
name the positioning aids we might use? - CORRECT ANSWERS✅✅troughs, gauze on
limbs, blocks for horses,
before the x ray is taken what needs to be done? - CORRECT ANSWERS✅✅you need to
measure your patient and make sure the machine is calibrated properly with the measurement
you took, patients should be clean and/or sedated if needed. all the info should be logged into
the computer.
when do we take more than 2 views? - CORRECT ANSWERS✅✅for certain exotics,
metastasis check or when structures overlap
what is the source image distance that the tube stand should be at? - CORRECT
ANSWERS✅✅40 inches
when do we use the bucky vs the table top? - CORRECT ANSWERS✅✅bucky - if the
animals is over 10 cm
tabletop if the animal is less than 10 cm
what are 2 postive contrast and what do they look like in the animal? what is the puropse of a
postive contrast? - CORRECT ANSWERS✅✅barium and iodine are positive. they appear
white on screen
purpose is that what iodine is water soluble and usually used for IV (bladder) and organs like
GI because it it chemical stable and has a low toxicity
barium is insouleble and is used for GI
what are two negative contrast agents and what do they look like? - CORRECT
ANSWERS✅✅gases like 02 and co2 and they appear black
patient is getting a contrast study what should you do? - CORRECT ANSWERS✅✅patients
needs a surgical flush within 6-8 of contrast
NPO for 12-24 hours
, give enema if needed
how often are we taking radiographs for barium in a GI study? - CORRECT
ANSWERS✅✅at the 0, 15,30,45 min marks. then every 30 mins to an hour once it has
reached the distal SI.
what are BIPS - CORRECT ANSWERS✅✅barium impregnated polythylene spheres
What are contraindications of a barium series? - CORRECT ANSWERS✅✅perforaation of
the alimentory tract
thorax is damaged
what type of tissue does ultrasound exmine? - CORRECT ANSWERS✅✅soft tissue
when doing an ultra sound what has the most reflectivity? what has the least? - CORRECT
ANSWERS✅✅most - metal and mineral
lease - water
what is positively charged and receives electrons and produces heat? - CORRECT
ANSWERS✅✅the anode/ rotating anode
what is negativly charged and provides source of electrons, aims electrons to anode and emits
electrons when heated? - CORRECT ANSWERS✅✅cathode
what does the collimotor do? - CORRECT ANSWERS✅✅controls the size of the x ray
beam as well as decrease scatter/unnecessary radiation
are larger does or several smaller does more dangerous? - CORRECT
ANSWERS✅✅smaller does have a higher chance at repair a high does would have a higher
frequency and more damage because of higher penetration
how can you limit radiation? - CORRECT ANSWERS✅✅-technique chart
-posistioning aids
