head tilt has an inner ear infection. What position would best visualize the
tympanic bullae?: Oblique

with gas: true
8. Which of the following controls the number of the x-rays produced?: mAs

quality of the repeat film?: Decrease kVp
15.The dorsoventral as apposed to the ventrodorsal position is best utilized for:
Smaller pocket pets such as rats and reptiles
16.When taking distal leg images of a horse, why is the hoof cleaned and packed?:

17.What material would be appropriate for packing the hoof prior to radiographs?:
Play-doh
18.When doing joint images of the horse, what is the minimum number of images
that need to be taken?: 2
19.The majority of imaging conducted on horses is of what body area?: Pelvis
, .
