AVTAA Veterinary Technician Specialty
Examination in Anesthesia & Analgesia
Practice Questions, Answers & Detailed
Explanations
Exam Coverage Summary
This comprehensive examination covers all essential domains of veterinary anesthesia and
analgesia as outlined by the Academy of Veterinary Technicians in Anesthesia and Analgesia
(AVTAA). The content encompasses foundational principles including anesthesia terminology,
pharmacology of induction agents, inhalant anesthetics, pre-medications, and reversal agents.
Clinical applications include patient assessment, ASA classification, monitoring techniques,
equipment operation, and troubleshooting. Pain management principles address nociceptive
pathways, analgesic classifications, multimodal approaches, and recognition of pain in various
species. Patient safety considerations include anesthesia machine maintenance, waste gas
exposure risks, emergency preparedness, and recognition of complications. Species-specific
considerations cover dogs, cats, equine, ruminants, swine, small mammals, and exotic species
with emphasis on anatomical and physiological differences that impact anesthetic management.
Perioperative care spans pre-anesthetic preparation, induction techniques, maintenance
protocols, recovery management, and fluid therapy calculations.
1. During the maintenance phase of general anesthesia, which of the following represents the
primary goal that directly impacts patient safety and surgical success?
A) Complete elimination of all reflexes
B) Stable cardiopulmonary values
, Page 2 of 100
C) Maximum muscle relaxation
D) Minimum anesthetic gas concentration
Correct Answer: B) Stable cardiopulmonary values
Stable cardiopulmonary values are essential during maintenance because they ensure adequate
tissue perfusion and oxygenation while preventing life-threatening arrhythmias and hypotension
that could lead to organ damage or death.
2. A veterinary technician is preparing to induce anesthesia in a geriatric dog that appears
quiet and calm. Compared to an active young dog of the same body weight, the amount of
induction agent required for this patient will likely be:
A) The same dose regardless of age or activity level
B) Approximately double the standard dose
C) Approximately one-quarter of the standard dose
D) Approximately three-quarters of the standard dose
Correct Answer: C) Approximately one-quarter of the standard dose
Older, debilitated patients have reduced metabolic capacity, decreased cardiac output, and
altered drug distribution, making them more sensitive to induction agents, often requiring
significantly lower doses than healthy young patients.
3. A technician notices the oxygen flow meter reads zero despite all efforts to establish flow.
The immediate priority action to prevent patient mortality is:
A) Check the oxygen tank pressure gauge
B) Replace the flow meter assembly
C) Disconnect breathing tubes from the endotracheal tube
D) Increase the vaporizer setting
, Page 3 of 100
Correct Answer: C) Disconnect breathing tubes from the endotracheal tube
When oxygen flow ceases, immediate disconnection of breathing tubes allows the patient to
breathe room air, preventing fatal hypoxia while troubleshooting the anesthesia machine
failure.
4. When performing a complete inventory of controlled substances in a veterinary practice,
federal regulations require this accountability measure to be conducted at which frequency?
A) Monthly
B) Annually
C) Every 2 years
D) Every 5 years
Correct Answer: C) Every 2 years
The Drug Enforcement Administration requires complete inventories of all controlled substances
every two years to ensure proper tracking, prevent diversion, and maintain regulatory
compliance in veterinary facilities.
5. A 10-pound canine patient requires mechanical ventilation with a tidal volume of 15 mL/kg.
The reservoir bag size that should be selected based on this calculation is:
A) 0.25 L
B) 0.5 L
C) 1.0 L
D) 2.0 L
Correct Answer: B) 0.5 L
, Page 4 of 100
The calculated tidal volume of 0.27 L rounds to the nearest available bag size of 0.5 L, which
provides adequate reserve volume while maintaining appropriate ventilation parameters for this
small patient.
6. The log records for which classification of controlled substances must be maintained
separately from all other practice records according to federal regulations?
A) Schedule III
B) Schedule IV
C) Schedule V
D) Schedule II
Correct Answer: D) Schedule II
Schedule II drugs have the highest potential for abuse among controlled substances used in
veterinary medicine and require separate record-keeping to ensure strict accountability and
prevent diversion.
7. A technician is monitoring a patient under anesthesia and observes that the SpO2 reading
has dropped below which percentage, indicating a medical emergency requiring immediate
intervention?
A) 95%
B) 90%
C) 85%
D) 80%
Correct Answer: C) 85%
An SpO2 below 85% represents severe hypoxemia that can rapidly lead to cardiac arrest and
brain damage, requiring immediate assessment of airway, breathing, and circulation
interventions.
