A technician draws 6 mL of euthanasia solution but notices a 0.2 mL air bubble remains. What should be done before injection?
Answer: Hold the syringe vertically with needle up and gently tap to float the bubble, then expel it
Tapping and expelling air ensures the full drug dose is delivered and prevents IV air embolism risk.
Which type of scale is most appropriate for accurately weighing neonatal kittens (< 200 g) for euthanasia dose calculation?
Answer: A gram-precision digital scale with a range of 0–500 g
A high-precision gram scale ensures accurate weight measurement for very small animals where dosing errors are most critical.
A technician uses an extension set (IV line) to administer euthanasia solution to a large animal. What must be confirmed about the set before drug delivery?
Answer: All clamps are open and the line has been flushed to remove air
Open clamps and an air-free line ensure unobstructed, accurate delivery of the full dose to the patient.
When verifying death in a large animal, a stethoscope is placed over the cardiac region for auscultation. How long should the technician listen before confirming cardiac arrest?
Answer: At least 2–5 minutes
AVMA guidelines recommend auscultating for a minimum of 2–5 minutes in large animals to confirm irreversible cardiac arrest.
A syringe is labeled 'for single use only.' A technician considers reusing it with a new needle after a first draw. What is the risk?
Answer: The plunger seal degrades, leading to inaccurate volume measurement on subsequent draws
Single-use syringes lose plunger seal integrity upon reuse, compromising dose accuracy and sterility.
A concentration of euthanasia solution is listed as 39% on the label. What does this concentration mean in mg/mL terms?
Answer: 390 mg/mL
A 39% solution means 390 mg of active ingredient per mL (39 g per 100 mL = 390 mg/mL).
During a field euthanasia, a technician lacks a stethoscope to confirm cardiac arrest. Which alternative method is acceptable per AVMA guidelines?
Answer: Palpation of a peripheral pulse combined with observation for cessation of respiration over several minutes
Absent peripheral pulse combined with cessation of breathing is an acceptable alternative when a stethoscope is unavailable.
