Q
  1. Volatile anesthetics _______ cerebral oxygen requirements, therefore, ____ doses _____ intracranial pressure (ICP)
A

Decrease, low, decrease

Higher doses cause ceerbral vasodilation and therefore ICP is elevated.

Q
  1. The main adverse effect of acepromazine is
A

antagonism of vascular alpha-1-adrenoreceptors, causing

vasodilatation,

decreased vascular resistance,

and arterial hypotension

Q
  1. True or False: The use of an anticholinergic with an alpha-2 adrenergic agonist decreases the work of the heart thus decreasing the risk of myocardial injury
A

False- increases the work of the heart thus risking myocardial injury because stroke volume is decreased even though heart rate is increased

Q
  1. Alphaxalone is a ______ anesthetic with ___________ cardiovascular and respiratory effects
A

steroid, minimal

17
Q
  1. What are the major effects and precautions of etomidate anesthesia in dogs and cats?
A

Effects: 1) Elicits no change in cardiovascular function, 2) Suppresses glucocroticoid synthesis by adrenal gland

Precautions: 1) High incidence of excitement (e.g. paddling, vacalization) particularly with inadequate preanesthetics, 2) Prolonged etomidate not recommended due to increased mortality from adrenal suppression

18
Q
  1. Which of the following statements is false regarding tiletamine anesthesia:
    a. it is classified as a imidazole anesthetic
    b. it exhibits adverse effects similar to ketamine but of greater intensity
    c. tachycardia and hypotension are most commonly observed
    d. recovery is unpredictable
A

A - is a dissociative anesthetic

19
Q
  1. True or False: All volatile anesthetics decrease heart rate, blood pressure, and minute ventilation
A

True

20
Q
  1. What are the major effects on the cardiovascular system of halothane?
A

Halothane depresses cardiac output more than the other agents, but maintains systemic peripheral resistance better than newer agents which are more potent vasodilators.

Halothane has higher incidence of arrhythmias due to sensitization of myocardium to catecholamines.

21
Q
  1. When using nitrous oxide with a rebreathing circuit at low gas flow rates, the administered gas mixture should contain at least __% oxygen.
A

50%

22
Q
  1. When using total intravenous anesthesia what parameters tend to decrease in a dose related fashion.
A

Heart rate, respiratory rate, and blood pressure, as with volatile agents

23
Q
  1. An animal under anesthesia is noted to have centrally positioned eyes which of the following statements is correct a. animal is to light and anesthesia needs to be increased b. animal is to deep and anesthesia needs to be decreased c. anesthesia is just right- no changes need to be made
A

B

24
Q
  1. Perfusion of vital organs is dependent on a mean arterial pressure of greater than____ mmHg a. 50 b. 60 c. 70 d. 80
A

B

25
Q
  1. Decreases in end-tidal carbon dioxide may indicate all of the following except: a. hypoventilation b. decrease in cardiac output and pulmonary perfusion c. increase in physiologic dead space d. equipment malfunction
A

A - hyperventilation

26
Q
  1. Anesthetic requirements are closely related to body temp with a ___% decrease in MAC for every degree-centigrade temperature drop a. 2 b. 3 c. 4 d. 5
A

D

27
Q
  1. True or False: If end tidal carbon dioxide consistently exceeds 60mmHg assisted ventilation should be provided.
A

TRUE

28
Q
  1. If mean arterial pressure falls below 60 mmHg what organ system requires immediate attention a. cardiovascular b. renal c. cerebrovascular d. hepatic
A

B

29
Q
  1. True or False: Partial opiod agonist exhibit a ceiling effect to analgesic efficacy, thus is an upper limit to the amount of analgesia that can be provided.
A

TRUE

30
Q
  1. True or False: Buprenorphine can be administered orally in cats as it exhibits trans buccal absorption and is 100% bioavailable orally at the same dose as when used parenterally.
A

TRUE

31
Q
  1. True or False: Ketamine has shown to increase the level of analgesia provided when used in combination with other analgesic agents particularly NSAIDs
A

F- particularly opiods -LOOK UP

32
Q
  1. Which of the following anesthetics should not be used for dogs and cats undergoing a thoracotomy due to the risk of developing post-operative pneumothorax a. isoflurane b. sevroflurane c. halothane d. nitrous oxide
A

D

33
Q
  1. Which of the following analgesic are recommended for use when performing a cesarean section in dogs and cats? a. buprenorphine b. epidural morphine c. NSAIDs d. all are safe to use
A

B

34
Q
  1. Prolonged administration of propofol results in: a. hypoglucosemia b. hyperglucosemia c. hypotriglyceridemia d. hypertriglyceridemia
A

D

35
Q
  1. True or False: In cats, the first sign of NSAID toxicity is gastrointestinal disturbances
A

FALSE - renal
