What breed of dog is a Westie? - CORRECT - ANSWERS West Highland White Terrier
What is the purpose of the Schirmer tear test? Why is this test done before other tests?
Describe how to perform this test. - CORRECT - ANSWERS This test is used to evaluate
tear production of the eye. It is performed first because other procedures can falsely
increase or decrease tear production. A strip should be folded in the notch while in its sterile
packging then removed. Place this strip between the lower eyelid and cornea near the lateral
canthus. Hold strip in place for one minute, remove, then measure it with the included chart.
You measure where the dry and wet part meet.
How would you restrain Sparky for an eye examination? - CORRECT - ANSWERS Restraint
is done with the dog sitting or in sternal recumbency on the table. One arm is wrapped
around the dog to keep the muzzle in place and the other arm is used to prevent the dog from
backing up. Sternal is preferred because you can use your body weight to help keep the dog
down.
Why is anesthetizing the eye important before performing this test? - CORRECT - ANSWERS
Tonometry involves placing the tool right against the eye. If insufficient numbing of the
cornea occurs, the animal may traumatize the eye during the procedure.
What is the function of a tonometer? Describe how to use this tool. - CORRECT - ANSWERS
The tonometer measures intraocular pressure. There is a variety available but all work in a
similar manner. The tonometer is first cleaned and checked prior to use. The tonometer is
placed on the anesthetized cornea with another person restraining the body and the head of
the animal.
The tonometer is placed perpendicular to the cornea for an accurate reading. The tip is then
lifted off the eye. Repeat the test two more times to get an average reading.
, What is the term for collecting urine using a needle and a syringe? - CORRECT - ANSWERS
Cystocentesis is the procedure of collecting urine with a needle and syringe
Describe how to restrain a dog for a cystocentesis - CORRECT - ANSWERS Cystocentesis
is performed by holding a dog in dorsal recumbency with the front limbs cranial and the hind
limbs caudal. You may also use lateral recumbency or standing.
Where is the cephalic vein located? Describe how you would restrain sparky for a blood draw.
- CORRECT - ANSWERS The cephalic vein is located on the cranial aspect of the radius.
One person will extend the arm and hold off from the other person to draw blood. The dog is
in sternal recumbency with the vein being rolled laterally.
The other technician is having difficulty finding the vein and asks you to try while she
restrains. How do you draw blood from the cephalic vein? - CORRECT - ANSWERS An
appropriately sized needle is advanced into the vessel at a 25 degree angle and aspirated
while doing so to maintain negative pressure. Verify that you are in the right spot by pulling a
flash of blood. After drawing blood you will apply pressure for 60 seconds.
The dog was estimated to be 9% dehydrated. The dog is no longer vomiting. Annie weights 75
pounds. Calculate the rehydration fluid volume based on the percent dehydration.
Maintenance fluid rate is 60 ml/kg/day. Please calculate the total fluids required for Annie for
that day. - CORRECT - ANSWERS Rehydration fluid= percent dehydration x kg body weight
x 10. So 75#=34kg, 34kg x 9% x 10= 3000ml or 3L
Maintenance fluids is 60ml/kg. So you take 60ml x 34kg = 2040ml/day.
Ongoing losses would include how many times they vomited or had diarrhea in the past 24 hr
and how many ml of that. That equation the amount of mL x how many times it happened =
____ ml x2 (for human error). Since this dog has stopped vomiting, we dont have to worry
about this.
