Which of the following is the MOST accurate method to confirm correct endotracheal tube placement?
Answer: Capnography showing a normal waveform
Capnography demonstrating a consistent CO2 waveform is the gold standard for confirming endotracheal intubation, as esophageal placement will not produce a waveform.
A patient recovering from anesthesia is shivering. Why is postanesthetic shivering clinically significant?
Answer: It increases oxygen consumption and cardiac workload
Shivering significantly increases oxygen demand and metabolic rate, which can be dangerous in compromised cardiac or respiratory patients.
Which drug is used to reverse benzodiazepine sedation in veterinary patients?
Answer: Flumazenil
Flumazenil is a competitive benzodiazepine antagonist at the GABA-A receptor that reverses sedation from diazepam or midazolam.
A dog on isoflurane anesthesia has a mean arterial pressure (MAP) of 55 mmHg. Which intervention is the MOST appropriate first step?
Answer: Reduce the isoflurane concentration and provide an IV fluid bolus
Isoflurane causes dose-dependent vasodilation and hypotension; reducing its concentration while providing a fluid bolus addresses both the cause and the hemodynamic effect.
What is the purpose of preoxygenation before anesthetic induction in dogs and cats?
Answer: To extend the time before oxygen desaturation occurs if intubation is difficult
Preoxygenation denitrogenates the functional residual capacity, increasing oxygen reserves and providing extra time for safe intubation before desaturation.
Which of the following correctly describes the effect of hypothermia on drug metabolism during anesthesia?
Answer: It prolongs the duration of anesthetic drugs by slowing metabolism
Hypothermia decreases hepatic enzyme activity and reduces blood flow, slowing drug metabolism and prolonging the action of anesthetic agents.
During anesthesia, a patient's SpO2 reading suddenly drops to 85% but mucous membranes appear pink. What is the most likely cause of this discrepancy?
Answer: Pulse oximeter sensor artifact or poor probe placement
A discrepancy between low SpO2 and normal clinical appearance often indicates probe malposition, movement artifact, or poor perfusion at the sensor site rather than true hypoxemia.
