ICVA - International Council for Veterinary Assessment Exotic Animal Anesthesia Questions and Answers

Question 1

A veterinarian is preparing to anesthetize a 12-year-old blue-and-gold macaw for a surgical procedure.
Which anatomical feature is most critical to consider when selecting and placing an endotracheal tube in this patient?

Accepted Answer

The presence of complete tracheal rings, which contraindicates the use of a cuffed endotracheal tube.

Answer

The presence of a diaphragm, which requires higher inflation pressures.

Answer

The bifurcation of the trachea into bronchi within the cervical region, requiring a shorter tube.

Answer

The presence of an epiglottis, which can make visualization of the glottis difficult.

Question 2

A 2 kg domestic rabbit is scheduled for a dental procedure. The veterinarian wishes to use an anticholinergic to reduce salivary and respiratory secretions. Why is glycopyrrolate often considered a more effective choice than atropine in this species?

Accepted Answer

A high percentage of rabbits possess the enzyme atropinesterase, which rapidly hydrolyzes and inactivates atropine.

Answer

Atropine causes significant and prolonged hypertension in rabbits.

Answer

Glycopyrrolate provides superior postoperative analgesia compared to atropine.

Answer

Atropine is known to cause severe gastrointestinal stasis in rabbits, while glycopyrrolate does not affect motility.

Question 3

A 5-year-old male ferret with a suspected insulinoma is presented for an exploratory laparotomy. Which of the following pre-operative fasting recommendations is most appropriate to minimize anesthetic risk?

Accepted Answer

Fast for a short period of 2-4 hours to reduce the risk of regurgitation while minimizing the risk of severe hypoglycemia.

Answer

Fast for 12 hours to ensure an empty stomach, similar to a cat.

Answer

Fast for 8 hours but allow access to a high-sugar supplement like corn syrup.

Answer

Do not fast the ferret at all to prevent a hypoglycemic crisis.

Question 4

When preparing an anesthetic bath for koi using tricaine methanesulfonate (MS-222), what is the most critical step to ensure fish safety and reduce tissue irritation?

Accepted Answer

Adding sodium bicarbonate to buffer the acidic solution.

Answer

Chilling the water to 5°C to potentiate the anesthetic effect.

Answer

Using distilled water to ensure a pure solution.

Answer

Mixing the MS-222 powder with a small amount of ethanol to aid dissolution.

Question 5

A red-eared slider is induced for a shell fracture repair. Immediately following intravenous administration of an anesthetic agent, the turtle becomes profoundly apneic and bradycardic. Which physiological mechanism is the most likely cause of this response?

Accepted Answer

Diving reflex

Answer

Bezold-Jarisch reflex

Answer

Cushing's reflex

Answer

Bainbridge reflex

Question 6

A veterinarian is deciding between alfaxalone and propofol for intramuscular (IM) induction of a bearded dragon that is difficult to handle. Which of the following is a key advantage of alfaxalone over propofol for this specific route of administration in a reptile?

Accepted Answer

Alfaxalone can be administered effectively via the IM route, whereas propofol is generally recommended for IV/IO use only.

Answer

Alfaxalone provides significant postoperative analgesia, unlike propofol.

Answer

Propofol causes severe hypertension in reptiles when given IM.

Answer

Alfaxalone has a much shorter duration of action, allowing for faster recovery.
