A drug vial label reads '390 mg/mL' and the calculated dose for an animal is 1,170 mg. How many mL should be drawn?
Answer: 3 mL
1,170 mg ÷ 390 mg/mL = 3 mL; dividing total dose by concentration gives the volume to draw.
When measuring an animal's body weight for euthanasia dosing and only a floor scale is available, how should a fractious cat be weighed?
Answer: Weigh the handler holding the cat, then subtract the handler's weight
Weighing the handler with the animal then subtracting the handler's weight is a standard field technique for uncooperative patients.
What is the purpose of checking the plunger seal on a syringe before drawing up euthanasia solution?
Answer: To ensure a leak-free seal so the correct volume is delivered without loss
A damaged plunger seal can cause leakage, resulting in underdosing and failed euthanasia.
A technician must confirm death in a feline after euthanasia. Which combination of criteria meets AVMA guidelines for confirmation?
Answer: Absence of heartbeat by auscultation, no respiratory movement, and no response to stimuli for at least 1 minute
AVMA guidelines require multiple criteria (cardiac arrest, respiratory cessation, unresponsiveness) to confirm death.
A technician notices the needle has a barb after withdrawing it from a vial. What is the correct action?
Answer: Discard the needle and replace it with a new one before administering
A barbed needle causes unnecessary tissue trauma and must be replaced before administration.
In a shelter setting, a calibrated digital scale shows 'E' (error) when an animal is placed on it. What is the most likely cause?
Answer: The animal's weight exceeds the scale's maximum capacity
An 'E' error on a digital scale typically indicates the load exceeds the rated capacity of the device.
When drawing up controlled euthanasia solution from a multi-dose vial, why should the technician avoid introducing air bubbles into the syringe?
Answer: Air bubbles displace solution and cause inaccurate volume measurement
Air bubbles in the syringe reduce the actual volume of drug delivered, potentially leading to underdosing.
