topical anesthesia
A state in which a patient is aware or unaware of the surroundings but can be easily aroused by a noxious stimulant is referred to as:
sedation
A stage of anesthesia that has a sufficient loss of sensitivity to pain and muscle relaxation to allow for the performance of surgery without the pain or movement is:
surgical anesthesia

A complex that occurs too early is referred to as:
premature complex.
The advantage of using an oscillometric blood pressure monitor over a Doppler monitor is:
oscillometric BP monitors determine diastolic pressure and MAP in addition to systolic.
Neither the PaO2 nor the SpO2 gives an accurate measure of oxygen if which of the following is present in the patient?
anemia
Which of the following is true?
Epinephrine added to the local anesthetic causes constriction of the blood vessels in the area of the injection and decreases the rate of the drug absorption.

Intravenous crystalloid fluid administration at a rate of 20 mL/kg for 20 min
A complication of an anesthetized animal breathing room air would be:
a decrease in the PaCO2.
General duration of action for buprenorphine following intramuscular injection is thought to be:
6-12 hrs
The drug that is most similar to oxymorphone in duration and effect is:
hydromorphone
Clinical effects of NSAIDs are due to their inhibition of what chemical synthesis within the body?
Prostaglandin
The most appropriate drug for IM injection for induction is:
ketamine
In general, when compared to the IV dose, the dose of the induction drug for IM use is:
larger
While intubating a patient that has been induced with the appropriate amount of injectable induction agent, intubation should take place how quickly in order to keep the patient in the appropriate plane of Stage III?
1-2 min
Which of the following may cause a horse brief excitement or loss of sedation during the time period after giving sedation before anesthetic induction?
Moving the animal behind a squeeze gate or into the stocks
Which of the following is not a sign of appropriate sedation for standing chemical restraint?
Restlessness without external stimuli
Which of the following complications can arise if a horse’s halter is left on during anesthesia?
neuropathy
The main anesthetic concern in ruminants is:
regurgitation
You have been asked to intubate an adult cow. How is the procedure done?
Manually using a blind technique that includes one hand in the mouth guiding the tube
An adult ruminant is intubated and in a surgical stage of anesthesia but begins to breathe rapidly with very shallow respirations. What should be done with this patient?
place on a venitlator
What is the approximate total blood volume of a 100-g hamster assuming the patient is hemodynamically stable with circulating blood volume representing 70 mL/kg of body weight?
7.0 ml
When attempting to try and illicit a reliable signal for SpO2 on small rodents, the most accurate place is usually the:
hindfoot
When treating circulatory failure with blood transfusions in small mammals and rabbits, what is the likelihood of incompatibility during the initial transfusion?
rare
When is the largest portion of anesthetic-related deaths likely to occur?
post anesthetic period
The proper equation to determine cardiac output (CO), taking into consideration stroke volume (SR) and heart rate (HR), is:
CO = HR × SV.
A geriatric patient is defined as one that has reached what percentage of their life expectancy?
75%
