Flashcards in Chpt. 12 - Review Questions Deck (25):

When an animal scheduled for a surgical procedure is brought in by a neighbor who is in a hurry, the best thing to do is:

d. Have the neighbor sign the consent form and ensure that the owner is called before the procedure is initiated.


In preparation for an anesthetic procedure, you have drawn up a syringe of barbiturate and an identical syringe of saline. You are then called to the examination room to assist the veterinarian. About 10 minutes later you return to prepare the animal for induction. With the IV catheter in place, you are just about to inject some saline into the animal when you realize that you are not sure if the syringe contains saline. The best thing to do would be to:

d. Discard both syringes, label some new syringes, and start over.


You are about to use the anesthetic machine and notice that although the flow meter is working, the pressure gauge on the oxygen tank reads close to zero. The best thing to do would be to:

b. Change the oxygen tank.


While monitoring a patient on an anesthetic machine, you realize that the oxygen tank has become empty. The best thing to do would be to:

a. Disconnect the patient from the circuit, put on a new oxygen tank, and then reconnect the patient to the circuit.


If the pop-off valve is inadvertently left shut, it will:

c. Cause a significant rise of pressure within the circuit.


You look at the oxygen tank and note that 1000 psi of pressure is left in the tank, but the flow meter now reads zero and you cannot obtain a flow by twisting the knobs. The best thing to do would be to assume:

c. The animal is not getting oxygen, and you need to remove the animal from the circuit until a new machine is found or the problem is corrected.


A geriatric patient is considered to be one that:

d. Has reached 75% of its life expectancy.


Brain damage may occur when there is inadequate oxygenation of the tissues for longer than … minutes.

b. 4


When a technician is performing CPR alone, the ratio of cardiac compressions to ventilation should be:

d. 10:2


To ensure that the benefit an animal obtains from CPR is not lost, one should not discontinue cardiac compressions for longer than:

a. 3 to 5 seconds


True or False:
Respiratory arrest is always fatal.



One may suspect that the ET tube is malfunctioning even if it is in the trachea because:

a. Compression of the reservoir bag does not result in the raising of the chest
b. The animal is dyspneic
c. The animal cannot be kept at an adequate plane of anesthesia
d. The reservoir bag is not moving or is moving very little


One may suspect that the pop-off valve has been closed or that it is malfunctioning if the:

a. Reservoir bag is distended with air
b. Patient has difficulty exhaling


Administration of the normal rate of fluids (10mL/kg/hr) during an anesthetic procedure may result in overhydration in the:

a. Patient with cardiac disease
c. Pediatric patient


Brachycephalic dogs may be at increased anesthetic risk because of their:

b. Excess tissue around the oropharynx
c. Increased vagal tone
d. Small trachea in comparison with their physical body size


To decrease the anesthetic risk associated with a brachycephalic dog, the anesthetist may elect to:

a. Use atropine as part of the anesthetic protocol
b. Preoxygenate the animal before giving any anesthetic
c. Use an injectable anesthetic to hasten induction rather than masking
d. Ensure intubation is done quickly after induction


Animals that undergo cesarean section are at increased risk during anesthesia because of:

a. Decreased respiratory function
b. Increased chance of aspiration vomitus
c. Increased chance of hemorrhage
d. Increased workload of the heart


Anesthetic agents or drugs that one may want to avoid in the animal with cardiovascular disease include:

a. Halothane
c. Xylazine


An animal that has liver dysfunction may be hypoproteinemic and therefore requires … for induction compared with that needed for a normal dog.

b. Less barbiturate


Too light a plane of anesthesia may be the result of:

a. A flow rate that is too low
b. An incorrect vaporizer setting
c. Incorrect placement of the ET tube


Tachypnea may result from:

b. Increased levels of arterial CO2
d. Too light a plane of anesthesia


When the blood pressure drops the veterinarian may ask the technician to infuse a colloid. Which of the following is not a colloid?

b. Hypertonic saline


True or False:
Laryngospasm is more common in the dog than in the cat.



True or False:
Treatment of bradycardia can always be reversed with an anticholinergic.



Tachyarrhythmias in the cat are best treated with:

c. Propranolol
