Question 1

A veterinary technician must calculate the pentobarbital dose for a 45 kg dog at 87 mg/kg. What total dose (mg) is required?

Accepted Answer

3,915 mg

Answer

45 kg × 87 mg/kg = 3,915 mg; dose in mg equals body weight multiplied by the mg/kg rate.

Question 2

What is the purpose of the 'dead space' in a needle-syringe assembly, and how does it affect dose measurement?

Accepted Answer

Dead space holds residual drug after the plunger bottoms out, potentially leaving drug undelivered

Answer

Dead space is the volume of drug retained in the needle hub after full plunger depression, which may result in incomplete dose delivery.

Question 3

A technician uses a 3 mL syringe with 0.1 mL graduations versus a 12 mL syringe with 0.2 mL graduations to measure a 2.5 mL dose. Which syringe provides greater precision and why?

Accepted Answer

The 3 mL syringe, because its smaller graduations allow more accurate volume reading

Answer

Smaller graduation increments (0.1 mL vs. 0.2 mL) on the 3 mL syringe allow finer measurement precision.

Question 4

An animal scale has not been calibrated in over a year. What is the primary risk of using an uncalibrated scale for euthanasia dosing?

Accepted Answer

Inaccurate weight leads to incorrect drug dosing, risking underdose or failed euthanasia

Answer

Inaccurate weight measurements directly cause dosing errors; underdosing can result in failed or prolonged euthanasia.

Question 5

After confirming death by auscultation, a technician notices the animal has an involuntary muscle twitch. What does this indicate?

Accepted Answer

Post-mortem muscle activity, which is normal and does not indicate life

Answer

Post-mortem myoclonus (muscle twitching after death) is a normal physiological reflex and does not indicate survival.
