28

T/F: Dogs will often experience laryngospasm during intubation

False

Cats will often experience laryngospasm during intubation.

29

T/F: Rebreathing (circle) systems increase resistance for smaller patients

True

For this reason, we try to avoid using these rebreathing systems for small patients (guinea pigs, small cats, rats, etc.)

30

T/F: You should always use non-rebreathing systems for patients under 3 kg

True

31

Does this vaporizer have back-pressure compensation?

No.

This is a non-precision vaporizer. Only precision vaporizers have back-pressure compensation

31

T/F: alpha-2 agonists cause vasoconstriction & increased BP, followed by a reflex bradycardia

True

32

Name the agent that is used for reversal of benzodiazepines:

Flumazenil

33

Gas passing through the oxygen flowmeter is reduced from 50 psi to about ____ psi

15 psi

35

T/F: When inflating the cuff, there should be no escape of gas from around the endotracheal tube when the APL valve is closed and the rebreathing bag is squeezed to 30 cmH2O

FALSE

When inflating the cuff, there should be no escape of gas from around the endotracheal tube when the APL valve is closed and the rebreathing bag is squeezed to 20 cmH2O

When squeezed to 30 cmH2O, air should be able to escape around the tube. if not, air should be removed from the pilot balloon to prevent over-inflation

36

What is the mechanism of action (MOA) for Acepromazine?

Dopamine (D1 and D2) receptor antagonist

38

How many liters of oxygen can fit in an H Cylinder?

6600 L

39

What stage of anesthesia is considered anesthetic overdose?

Stage IV

41

T/F: Anal sphincter tone is a good indicator of anesthetic depth

True

Tight in Stage II; relaxes thereafter

43

If the patient is holding their breath out of excitement, which stage of anesthesia is the patient likely in?

Stage I

44

T/F: Charcoal absorption systems are useful because they absorb halogenated anesthetic gases, N2O, and CO2

False

Charcoal absorption systems absorb halogenated gases (iso, sevo, des), but do NOT absorb N2O or CO2

45

T/F: Butorphanol is a partial mu agonist and an antagonist at kappa receptors

False!

Buprenorphine is a partial mu agonist and an antagonist at kappa receptors

Butorphanol is an agonist at kappa receptors and partial mu receptor agonist/antagonist

46

T/F: Precision vaporizers can be used with rebreathing or non-rebreathing systems

True

47

T/F: Doppler provides reliable detection of systolic pressure, but is generally unreliable for diastolic pressure

True

48

T/F: Nitrous oxide can produce general anesthesia on its own

False

49

What is the SVP for Isoflurane at 20oC?

240 mmHg

50

The check valve prevents transfilling of one tank to another. If this valve breaks, what would happen to the temperature as a result of rapid transfilling?

Temperature would increase

**risk of FIRE**

51

Would these hoses be used for re-breathing or non-rebreathing systems?

rebreathing

52

Name the agent that is used to reverse pure mu and mixed agonist/antagonists because of its high affinity for mu and kappa receptors

Naloxone

53

What is the mechanism of action (MOA) of barbiturates?

↓ GABA dissociation from GABAA receptor

Direct activation of GABAA receptor Cl- channel

54

T/F: Propofol is a rapid-acting, long duration induction agent

False

Propfol is rapid-acting, ultra-short duration (<20 mins)

55

What is the mechanism of action of Propofol?

Enhances inhibitory effects of GABA at GABAA receptors

56

Induction and maintenance of general anesthesia with intravenous drugs is termed:

Total Intravenous Anesthesia (TIVA)

57

Simultaneous use of injectables and inhalant for general anesthesia is termed:

Partial Intravenous Anesthesia (PIVA)

58

Plasma concentration (Cp) of IV anesthestic drugs is at 90% of Cp steady state after ____ half-lives

3.3

Plasma concentration (Cp) of IV anesthestic drugs is at 90% of Cp steady state after 3.3 half-lives

59

Clearance = dose/AUC

This is not a question, but remember it anyway.

Yeah.

 

60

What is the consequence of leaving the APL closed for a long period of time?

Build of pressure leading to barotrauma
