Homework 7 Flashcards
When an animal scheduled for surgery is brought in by the owner’s neighbor, who is in a
hurry, the best thing to do is:
Have the neighbor sign the consent form.
Ensure that the owner is called before the procedure is initiated and confirm the owner’s wishes
You have an anesthetic patient that is premedicated and ready for anesthetic induction. An IV
catheter is in place and your endotracheal intubation materials are prepared. You draw up
alfaxalone in one syringe and saline in a second syringe. Both are clear liquids. You place the syringes on the counter near where the patient will be induced. How is the best way to
assure which drug is in which syringe?
Label each syringe with the drug content and include the patient’s name.
Carbon Dioxide absorbing material should be changed….
any or all of the above depending on which occurs first
While monitoring an animal under isoflurane anesthesia on a partial rebreathing system, your
oxygen tank is getting low. The surgery is going to take longer than expected and you realize
you will run out of oxygen before the surgery is over. What is the best course of action?
Have a colleague prep a second isoflurane anesthesia machine for you with an appropriate amount of oxygen. Then, disconnect the patient from the first machine and reconnect to the second machine.
If no other anesthetic machine is available, have a colleague get another oxygen tank with enough oxygen, disconnect the patient from the machine and quickly, reattach the new
tank, and reconnect the patient to the machine.
During an anesthetic procedure how often should the oxygen flow meter be checked?
Every 5 minutes
During an anesthetic procedure, what common item(s) for suction are discussed to remove
mucus or blood from an obstructed endotracheal tube?
A cut down feeding tube and 20 ml syringe
Which of the following is / are TRUE for Pediatric Patients that are undergoing anesthesia?
The dose of injectable anesthetics administered is often 1/2 to 2/3 the dose given to
mature animals.
A geriatric patient is defined as…
One who has reached 75 % of the average life expectancy of that species and breed
Brachycephalic animals may
need to be preoxygenated prior to anesthetic induction include parasympatholytics (anticholinergics) in the anesthetic protocol have to have the endotracheal tube stay in place long into the recovery phase
Which of the following induction agents is especially a good choice for cardiac patients?
Etomidate
Which of the following is / are TRUE for Respiratory Impaired Patients that are undergoing anesthesia?
Propofol Induction may be an advantage due to its’ resulting bronchodilation.
During recovery the endotracheal tube should not be removed until the patient has a strong swallowing reflex.
An opioid partial agonist like buprenorphine, may be a good choice as a premedication.
Which of the following is / are TRUE for Renal Impaired Patients that are undergoing anesthesia?
Inhalation agents for anesthetic maintenance are the best choice since they are eliminated through exhalation.
A pregnant dog, undergoing anesthesia for a cesarean section should….
have preoxygenation techniques administered
Which of the following clinical signs, when monitoring an adult medium sized canine anesthetic patient, informs the anesthetist that the patient is too deeply anesthetized?
central position of the globe (eye), absent palpebral reflex, 3 breaths/minute, 50
heart beats/minute, absent jaw tone, CRT 2.5 seconds, pale mucous membranes.
Basic Life Support (BLS) of CPR includes….
chest compressions and intubation / ventilation
Which of the following statements is /are TRUE for CPR ventilation?
An intubated patient should have 100% oxygen delivered, if possible, at 10 breaths /minute
An intubated patient, if air is delivered via an Ambu bag, should have breaths delivered at 10/ minute.
If a patient is not intubated, two quick breaths should be delivered via mouth-to-snout ventilation every 30 chest compressions.
CPR compressions should…
occur at a rate of 100 to 120 compression / minute.
occur continuously for 2 minutes with a brief pause to change compressors and patient evaluation.
compress the chest by 1/3 to 1/2 of its width followed by full elastic recoil.
What is the most common cause of death of the postanesthetic period patient?
Dyspnea from upper airway obstruction
If the pop-off valve is inadvertently left closed which of the following would occur?
Pressure within the circuit will rise which can lead to increased pressure within the lungs.
Continued pressure can result in alveolar rupture, decrease blood return from the vena cava and pneumothorax.
What is the minimum amount of time for brain damage to occur when there is inadequate oxygenation of the tissues?
5 minutes
Which of the following premedications should be avoided for use in a patient with cardiovascular disease?
Ketamine
This anticholinergic / parasympatholytic is used to prevent and treat bradycardia secondary to increased parasympathetic tone. Can be helpful with patients experiencing asystole or pulseless electrical activity (PEA)
Atropine
This medication is used to stimulate the respiratory center and the central nervous system.
Doxapram
This benzodiazepine is used to treat seizures and can be administer IV or rectally as a suppository. It can be used in the Post-Arrest Period.
Diazepam
This powerful sympathetic nervous system stimulant increases peripheral vascular tone, increases the strength of heart contractions and increases heart rate.
Epinephrine
This local anesthetic can also be administered to treat ventricular tachycardia.
During CPR it can be used IV to treat Ventricular Fibrillation or Pulseless Ventricular Tachycardia.
Lidocaine
This reversal agent is an antagonist to opioids.
Naloxone
This medication is used to increase vascular resistance differently than Epinephrine
Vasopressin
