Question 2

Question
What purpose does the Murphy’s eye serve on an endotracheal tube?

Question 3

Question
If an endotracheal tube is longer than the thoracic inlet, there is:
Answer
  • an increased risk of mechanical dead space.

Answer
  • Pressure-reducing valve
  • Tank pressure gauge
  • Vaporizer
  • Line pressure gauge

Question 11

Question

Answer
  • Pressure-reducing valve
  • Flowmeter
  • Vaporizer
  • Line pressure gauge

Question 12

Question
How does a flowmeter set below 100 mL/kg/min affect the concentration of anesthetic in the circuit?
Answer
  • Increases the actual concentration of anesthetic
  • Does not affect the concentration of anesthetic
  • Lowers the actual concentration of anesthetic
  • The flowmeter cannot be set lower than 100 mL/kg/min

Question 13

Question
A normal concentration of isoflurane to maintain a premedicated 20-kg dog would be approximately:
Answer
  • 5%
  • 0.5%
  • 6%
  • 1.5%

Question 14

Question
What should be done if a bottle of inhalant anesthetic is accidentally dropped and breaks?
Answer
  • Mop up the liquid with a wet mop.
  • Mop up the liquid with paper towels.
  • Evacuate the room immediately and allow the room to air out until the liquid is completely evaporated.
  • There is no reason to do anything as the liquid will evaporate.

Question 15

Question
You have been asked to manage general anesthesia on a horse. What type of system would be most appropriate?
Answer
  • Closed rebreathing system
  • Semiclosed rebreathing system
  • Rebreathing system
  • Partial rebreathing system

Question 16

Question
Failure to adjust which of the following devices results in a buildup of excess pressure or volume of gases within the circuit and may damage the animal’s lungs?
Answer
  • Unidirectional valve
  • Pop-off valve
  • Pressure manometer
  • Air intake valve

Question 17

Question
