A veterinary technician must calculate the pentobarbital dose for a 45 kg dog at 87 mg/kg. What total dose (mg) is required?
Answer: 3,915 mg
45 kg × 87 mg/kg = 3,915 mg; dose in mg equals body weight multiplied by the mg/kg rate.
What is the purpose of the 'dead space' in a needle-syringe assembly, and how does it affect dose measurement?
Answer: Dead space holds residual drug after the plunger bottoms out, potentially leaving drug undelivered
Dead space is the volume of drug retained in the needle hub after full plunger depression, which may result in incomplete dose delivery.
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?
Answer: The 3 mL syringe, because its smaller graduations allow more accurate volume reading
Smaller graduation increments (0.1 mL vs. 0.2 mL) on the 3 mL syringe allow finer measurement precision.
An animal scale has not been calibrated in over a year. What is the primary risk of using an uncalibrated scale for euthanasia dosing?
Answer: Inaccurate weight leads to incorrect drug dosing, risking underdose or failed euthanasia
Inaccurate weight measurements directly cause dosing errors; underdosing can result in failed or prolonged euthanasia.
After confirming death by auscultation, a technician notices the animal has an involuntary muscle twitch. What does this indicate?
Answer: Post-mortem muscle activity, which is normal and does not indicate life
Post-mortem myoclonus (muscle twitching after death) is a normal physiological reflex and does not indicate survival.
Which measurement instrument should be used to verify the internal diameter and gauge of a needle before IV administration to a fragile geriatric animal?
Answer: Read the manufacturer's label on the needle packaging, which specifies gauge and length
Needle gauge and length are specified on the manufacturer's packaging label and should always be verified before use.
A controlled substance log requires recording the volume drawn from a vial and any wastage. A technician draws 5 mL but uses only 4.5 mL. How is this properly documented?
Answer: Record 5 mL drawn and 0.5 mL wasted, witnessed by a second authorized staff member
DEA regulations require documenting both the amount drawn and any wastage, with a witness signature for controlled substances.
