Question 1

On a hospitalized patient's treatment sheet, a veterinarian writes an order to administer an ophthalmic ointment "1/4 inch strip OD q6h" and an otic medication "4 drops AU b.i.d." Based on accepted veterinary prescription abbreviations, this order instructs the technician to apply the ophthalmic ointment into the _____ four times daily and the otic drops into both ears twice daily.

Accepted Answer

right eye

Answer

both eyes

Answer

right ear

Answer

left eye

Question 2

During routine quality assurance testing of a clinic's steam autoclave, a surgical technician places a vial containing Geobacillus stearothermophilus spores inside the center of a standard surgical pack before running a sterilization cycle. What is the specific function of this indicator, and how must its outcome be handled?

Accepted Answer

It acts as a biological indicator that verifies microbial spore destruction across all sterilization parameters, and the result must be documented in a log.

Answer

It serves as a chemical integrator that changes color immediately upon reaching 121°C, requiring only external pack labeling.

Answer

It functions as an external process indicator to distinguish autoclaved packs from unsterilized packs without requiring logbook documentation.

Answer

It measures residual ethylene oxide gas dissipation during the aeration cycle and is discarded immediately after the load cools.

Question 3

While processing reusable cloth surgical drapes and gowns contaminated with infectious exudate from a septic peritonitis surgery, which decontamination, laundering, and packaging protocol must the technician follow prior to steam sterilization?

Accepted Answer

Presoak the infectious laundry in a solution of 9 parts water to 1 part household bleach, wash, dry at high temperatures of 65-70°C, and include a sterility indicator in the autoclaved pack.

Answer

Auto-sterilize the soiled linens immediately upon removal from the operating suite to coagulate proteins before washing, then dry at 40-45°C.

Answer

Presoak the contaminated linens in a 1:32 quaternary ammonium bath, air-dry at room temperature (20-22°C), and autoclave without internal indicators.

Answer

Immerse the linens in undiluted 100% household bleach for 60 minutes, rinse with cold tap water, and fold into packs while damp to generate extra steam.

Question 4

While performing a Comprehensive Oral Health Assessment and Treatment (COHAT) on an anesthetized beagle, a veterinary technician uses a powered ultrasonic scaler to remove heavy supragingival calculus from the maxillary fourth premolars. Which technique prevents iatrogenic thermal pulp necrosis and enamel damage during mechanical scaling?

Accepted Answer

Keeping the side of the working tip parallel (0 to 15 degrees) to the tooth surface with continuous water-mist lavage, limiting contact on any single tooth to under 10 to 15 seconds at a time.

Answer

Shutting off the water coolant spray to improve visibility of the gingival sulcus and scaling with the sharp point of the instrument.

Answer

Using a high-speed polishing handpiece at 10,000 rpm with coarse dry pumice prior to removing supragingival calculus.

Answer

Holding the pointed tip perpendicular (90 degrees) to the enamel surface while applying firm pressure for 25 seconds per tooth.

Question 5

A mixed-animal veterinary hospital receives an EDTA-anticoagulated whole blood sample collected from a 4-year-old Holstein cow and another EDTA blood sample from a 6-year-old Labrador Retriever. Because a courier vehicle was delayed, the canine sample remained in warm transit for 16 hours before arriving at the clinic laboratory, whereas the bovine sample was collected on-site 10 minutes before processing.

The veterinary technician analyzes both samples on an automated hematology analyzer, which directly measures mean corpuscular volume (MCV) and red blood cell (RBC) count to generate a calculated hematocrit using the formula HCT = (MCV x RBC count) ÷ 10. To cross-check the automated values, the technician also prepares microhematocrit capillary tubes from both samples to measure the spun packed cell volume (PCV).

When setting up the microhematocrit centrifuge for both species and interpreting discrepancies between the calculated HCT and spun PCV, which centrifugation protocol and hematologic interpretation are correct?

Accepted Answer

Centrifuge the bovine capillary tube for 10 minutes and the canine tube for 3 minutes; expect the aged canine sample to show a falsely elevated MCV and calculated HCT due to erythrocyte swelling during storage.

Answer

Centrifuge both capillary tubes for 2 minutes; expect the spun PCV and calculated HCT to remain identical in the aged canine sample because plasma trapping offsets cell volume changes.

Answer

Centrifuge the bovine capillary tube for 10 minutes and the canine tube for 3 minutes; expect in vitro hemolysis in the aged canine sample to falsely elevate the RBC count and calculated HCT.

Answer

Centrifuge the bovine capillary tube for 3 minutes and the canine tube for 10 minutes; expect the aged canine sample to show a falsely decreased MCV and calculated HCT due to osmotic shrinkage.

Question 6

A veterinary technician is performing diagnostic parasitology evaluations on canine blood and fecal specimens. Which TWO laboratory procedures or diagnostic interpretations are accurate? (Select TWO)

Accepted Answer

Conducting a Baermann funnel test on fresh unrefrigerated feces isolates motile lungworm larvae that migrate into warm water and settle by gravity.

Accepted Answer

Performing a Modified Knott's test with 2% formalin and methylene blue stain concentrates microfilariae and lyses erythrocytes to differentiate Dirofilaria sp. from Acanthocheilonema (Dipetalonema) sp.

Answer

Evaluating a direct wet mount of whole blood identifies Dirofilaria immitis microfilariae by their rapid progressive forward movement out of the field of view and button-hook tail.

Answer

Using the McMaster chamber with standard sodium nitrate flotation solution is the preferred method to recover heavy operculated trematode ova without osmotic distortion.

Answer

Applying clear adhesive tape to the perianal region of a dog is used to diagnose canine pinworm (Oxyuris equi) infection.
