VTNE Anesthesia Management 5

Question 1

Which of the following is the MOST accurate method to confirm correct endotracheal tube placement?

Accepted Answer

Capnography showing a normal waveform

Answer

Capnography demonstrating a consistent CO2 waveform is the gold standard for confirming endotracheal intubation, as esophageal placement will not produce a waveform.

Question 2

A patient recovering from anesthesia is shivering. Why is postanesthetic shivering clinically significant?

Accepted Answer

It increases oxygen consumption and cardiac workload

Answer

Shivering significantly increases oxygen demand and metabolic rate, which can be dangerous in compromised cardiac or respiratory patients.

Question 3

Which drug is used to reverse benzodiazepine sedation in veterinary patients?

Accepted Answer

Flumazenil

Answer

Flumazenil is a competitive benzodiazepine antagonist at the GABA-A receptor that reverses sedation from diazepam or midazolam.

Question 4

A dog on isoflurane anesthesia has a mean arterial pressure (MAP) of 55 mmHg. Which intervention is the MOST appropriate first step?

Accepted Answer

Reduce the isoflurane concentration and provide an IV fluid bolus

Answer

Isoflurane causes dose-dependent vasodilation and hypotension; reducing its concentration while providing a fluid bolus addresses both the cause and the hemodynamic effect.

Question 5

What is the purpose of preoxygenation before anesthetic induction in dogs and cats?

Accepted Answer

To extend the time before oxygen desaturation occurs if intubation is difficult

Answer

Preoxygenation denitrogenates the functional residual capacity, increasing oxygen reserves and providing extra time for safe intubation before desaturation.
