A technician needs to administer 3 mL of pentobarbital using a 12 mL syringe. How should the dose be measured to ensure accuracy?
Answer: Draw to the 3 mL graduation mark while keeping the syringe at eye level
Accurate measurement requires reading the syringe graduation at eye level to avoid parallax error.
When using a stethoscope to confirm cardiac arrest after euthanasia, where should the chest piece be placed on a dog?
Answer: Left axillary region (left armpit/chest wall area)
The left axillary/cardiac region provides the best auscultation of heart sounds in canines.
A scale used to weigh animals for euthanasia drug dosing reads 0.3 kg when unloaded. What is this called and how should it be corrected?
Answer: Zero error; tare the scale before use
A non-zero reading with no load is a zero error, corrected by taring (zeroing) the scale before weighing.
Which needle gauge is most appropriate for IV administration of euthanasia solution to a medium-sized dog (20 kg)?
Answer: 20–22 gauge
20–22 gauge needles provide adequate flow for IV euthanasia solution while minimizing vascular trauma in medium-sized dogs.
A technician uses a pulse oximeter on a sedated animal prior to euthanasia and gets a reading of 96%. What does this value indicate?
Answer: Oxygen saturation is within normal range
SpO2 of 96% is within the normal range (95–100%), indicating adequate hemoglobin oxygenation.
After euthanasia, a technician listens for heart sounds for 60 seconds and hears nothing. What additional step confirms cessation of cardiac activity?
Answer: Check for a pulse and absence of respiratory movement simultaneously
Confirming death requires checking for absent pulse and respiratory movement in addition to cardiac auscultation.
A 60 mL catheter-tip syringe is used for large animal euthanasia. What is the primary advantage of a catheter-tip over a luer-lock tip?
Answer: It connects directly to large-bore tubing without a needle for high-volume delivery
Catheter-tip syringes connect to large-bore extension sets for rapid, high-volume drug delivery in large animals.
