VTNE Veterinary Anesthesia 4

Question 1

A patient under anesthesia has a mean arterial pressure (MAP) of 48 mmHg. Which intervention should be attempted FIRST?

Accepted Answer

Reduce the anesthetic agent concentration

Answer

Reducing the inhalant anesthetic concentration is the first step since most inhalants cause dose-dependent cardiovascular depression; this is the most direct corrective action.

Question 2

Which nerve block technique would be MOST appropriate to provide dental analgesia for a maxillary canine tooth extraction in a dog?

Accepted Answer

Infraorbital nerve block

Answer

The infraorbital nerve block desensitizes the maxillary teeth (rostral to the 4th premolar) and surrounding tissues, making it ideal for maxillary canine extraction.

Question 3

What is the significance of a 'vaporizer out of circuit' (VOC) arrangement compared to a 'vaporizer in circuit' (VIC) arrangement?

Accepted Answer

VOC vaporizers deliver more precise, flow-independent concentrations

Answer

Out-of-circuit (VOC) vaporizers use a precision variable bypass design that delivers accurate agent concentrations independent of fresh gas flow rate.

Question 4

A rabbit is anesthetized and becomes apneic. Which route is MOST appropriate for emergency drug administration if IV access is not available?

Accepted Answer

Intraosseous

Answer

The intraosseous (IO) route provides rapid access to the systemic circulation in emergencies when IV access cannot be established, delivering drugs with similar speed to IV.

Question 5

Which of the following describes the Guedel classification Stage III, Plane 2 of anesthesia?

Accepted Answer

Surgical anesthesia with regular respiration and loss of palpebral reflex

Answer

Stage III, Plane 2 represents surgical anesthesia characterized by regular respiration, loss of the palpebral reflex, and absent response to surgical stimulation.
