Lab 4 Quiz Sheep Anesthesia

Question 1

What is the minimum acceptable Doppler (systolic) blood pressure in an anesthetized sheep?

60 mmHg

80 mmHg

100 mmHg

110 mmHg

Answer 1

80 mmHg

Question 2

Atropine should be administered to sheep pre-induction to decrease the amount of saliva they produce which will help facilitate intubation.

True
False

Answer 2

False

Question 3

Which of the following oxygen flow rates would be appropriate for the maintenance of inhalant anesthesia in a 40 kg sheep on a circle system?

0.3 L/minute
1 L/min
4 L/min
6 L/min

Answer 3

1 L/min

Question 4

Which of the following circumstances will not predispose a sheep to developing bloat when undergoing general anesthesia?

Not fasting before anesthesia
Administration of air into the stomach (esophageal intubation)
IPPV
Administration of atropine

Answer 4

IPPV

Question 5

During sheep anesthesia, you check the systolic blood pressure on a preplaced oscillometric blood pressure cuff and observe that the systolic BP is 70 mmHg and heart rate 110 bpm. What should you do?

Check the cuff and make sure the cuff width is 20% of the circumference of the limb
Nothing. This is a normal systolic blood pressure for a sheep.
Check your patient’s depth and turn down the vaporizer
Give atropine

Answer 5

Check your patient’s depth and turn down the vaporizer

Question 6

Which of the following monitors would be MOST APPROPRIATE to confirm tracheal intubation in the sheep?

ECG
Doppler
Pulse oximeter
Capnograph

Answer 6

Capnograph

Question 7

The surgeon notifies you that the procedure is complete thus you decide to turn off your vaporizer and wake up your sheep. Which of the following steps is incorrect as you prepare to extubate your sheep?

Increase your O2 flow
Place your animal in sternal recumbency
Untie the endotracheal tube and deflate your cuff
Position the nose down for drainage of saliva and regurgitant material

Answer 7

Untie the endotracheal tube and deflate your cuff

Question 8

Which of the following premedication combinations would be MOST APPROPRIATE for a sheep undergoing surgical castration?

Xylazine + Butorphanol
Acepromazine + Morphine
Detomidine + Atropine
Xylazine + Hydromorphone

Answer 8

Acepromazine + Morphine

Question 9

Which of the following is NOT a potential side effect of Intermittent Positive Pressure Ventilation (IPPV) in a sheep?

Hypoxemia due to low fraction of inspired O2 (FiO2)
Pulmonary barotrauma from an unnoticed closed APL valve
Decreased venous return and hypotension
Deeper anesthetic plane

Answer 9

Hypoxemia due to low fraction of inspired O2 (FiO2)
