answer

8

question

answer

progression from light to moderate anesthesia

question

If the rectum of a patient is covered by a surgical drape, or is otherwise inaccessible to the anesthetist, a rough estimate of body temp. can be obtained by?

answer

touching the patients feet or ears

question

Throughout anesthesia, the animal's temp. should be maintained as close to normal as possible. Hypothermia can be prevented by all of the following measures except:

answer

warming the stainless steel V trough before using it

question

Malignant hyperthermia is a potentially fatal syndrome to the anesthetized patient. Which of these species is most prone to this condition?

answer

pigs (porcine)

question

Which statement concerning eye position, pupil size, and responsiveness to light as indicators of anesthetic depth is least accurate?

answer

in stage lll, plane 3 of anesthesia, the eyes are usually central to slightly eccentric, with normal pupils that are responsive to light.

question

The presence or absence of salivary and lacrimal secretions may give clues regarding anesthetic depth. In an animal that has not received an anticholinergic, which statement concerning observance of these secretions is most accurate?

answer

tear and saliva production diminishes as anesthetic depth is increased

question

The anesthetized patient may respond to surgical stimulation if the anesthetic depth is inadequate. Response to a painful stimulus may be indicated by all of the following except?

answer

a decrease in lacrimation and salivation

question

A 10 year old dog has been anesthetized for removal of a skin tumor and is now maintained on a 2% isoflurane. The anesthetist observes that its respirations are 8/min. and shallow, its heart rate is 80 beats/min, its pupils are centrally positioned, its jaw tone is slack, and all of its reflexes are absent. This animal is in what stage and plane of anesthesia?

answer

stage lll, plane 3

question

A 10 year old dog has been anesthetized for removal of a skin tumor and is now maintained on 2% isoflurane. The anesthetist observes that its respirations are 8/min and shallow, its heart rate is 80 beats/min, its pupils are centrally positioned, its jaw tone slack, and all of its reflexes are absent. What should be your response or actions to the condition of this animal?

answer

you should reduce the vaporizer setting to 1.5% isoflurane and continue to monitor for signs of decreased depth

question

The estimated blood volume in dogs is:

answer

75 ml/kg

question

Tachycardia in an anesthetized patient may be an indication of any of the following except?

answer

xylazine overdose

question

A cardiac rhythm disturbance detected shortly after induction of anesthesia may be the result of any of the following except?

answer

breathing oxygen enriched air

question

Hypothermia has become significant in a 4 kg anesthetized cat. The best way to restore body heat is?

answer

to warm the air in the breathing circuit by some method

question

In a cat that is too deeply anesthetized, all of the following may be present except?

answer

voluntary movement

question

An isoflurane anesthetized cat suddenly begins breathing 30 times a minuet during a surgical procedure. Your first response should be to:

answer

evaluate vital organ function and endotracheal tube placement and make necessary adjustments

question

If a dog is too deeply anesthetized, all of the following may be seen except?

answer

increased jaw muscle tone

question

The only accurate way to evaluate the effectiveness of respiration is by?

answer

measuring the arterial blood oxygen and carbon dioxide partial pressures

question

Which of the following would NOT cause pale m.m.?

answer

hyperthermia

question

The patient is in an excessively deep plane of anesthesia. Which answer would not be an explanation?

answer

the endotracheal tube is kinked

question

A dog under anesthesia has a heart rate of 230 beats/min. Which of the following is the best explanation?

answer

the patient is in too light a plane of anesthesia

question

It is generally safe to extubate the patient when the patient:

answer

swallows

question

A canograph measures:

answer

expired CO2

question

The piece of equipment that facilitates intubating a patient is the:

answer

layngoscope
