The minimum acceptable heart rate for an anesthetized large breed dog is __________ bpm.
70
100
60
80
Tachypnea is:
An increase in respiratory rate
A decrease in respiratory depth (tidal volume)
An increase in respiratory depth (tidal volume)
A decrease in respiratory rate
A patient that has been anesthetized will often have a:
Mild metabolic acidosis
Mild respiratory acidosis
Mild metabolic alkalosis
Mild respiratory alkalosis
Pulse oximetry allows accurate estimation of:
Blood gas values
Percent saturation of hemoglobin with oxygen
Arterial blood pressure
Pulse pressure
Which of the following statements about body temperature is incorrect?
Circulating warm water blankets should be set at 45° C (approximately 111° F).
Dangerous CNS depression and changes in cardiac function may be seen at body temperatures less than 32° C (89.6° F).
Ideally, IV fluids should be warmed to about 37.5° C (approximately 100° F) before administration to surgical patients.
Body temperatures of 32° C to 34° C (89.6° F to 93.2° F) cause prolonged anesthetic recovery.
An animal under surgical, stage III anesthesia would exhibit which of the following signs?
Regular respiration
Dilated pupils
Brisk palpebral reflex
Pale mucous membranes commonly indicate all of the following except:
Anemia
Decreased perfusion
Blood loss
Hypertension
Which of the following statements about nystagmus as a monitoring tool is/are accurate?
Nystagmus is commonly seen in horses in very light anesthesia.
In a horse, a “divergent eye sign” is typically associated with an adequate plane of anesthesia for surgery.
Ruminants rarely show nystagmus under anesthesia.
Nystagmus is not a useful indicator of anesthetic depth in small animals.
All are correct
An ETCO2 level of 65 would commonly be caused by:
Hypothermia
Decreased tidal volume
Detachment of the endotracheal tube from the connector
Hyperventilation
A 20-kg dog has been anesthetized by mask induction with isoflurane and after intubation is maintained on 2% isoflurane with a flow rate of 2 L/min of oxygen. The heart rate is 80 bpm, respiratory rate is 4 breaths/min and shallow, the jaw tone is fully relaxed, and all reflexes are absent. This animal is most likely in what stage of anesthesia?
Stage III, deep
Stage III, surgical
Stage II
Stage III, light
Like people, domestic animals tend to readily show that they are in pain.
True
False
Pain tolerance varies widely between species and individuals within a species.
True
False
Administering analgesics after pain occurs is often just as effective as giving them before it occurs.
True
False
Even though pain has many damaging consequences, it can also be beneficial by limiting activity.
True
False
Even though multiple analgesics are often given concurrently, it is recommended that no more than one NSAID be given to a patient at a time.
True
False
Lidocaine, bupivacaine, or tetracaine can be used topically to reduce pain associated with minor procedures such as urethral catheterization.
True
False
Bilateral infraorbital and mandible dental blocks can be used to provide analgesia for dental extractions of the upper and lower dental arcades.
True
False
Opioids classified as partial agonists have a decreased effect but very similar side effects to pure agonists.
True
False
Giving butorphanol with a fentanyl patch will maximize the analgesic effects of the patch.
True
False
Diazepam does not provide pain relief.
True
False
Because it can cause heart toxicity, lidocaine is not recommended for use in cats.
True
False
Large animals do not experience pain in the same way as small domestic animals and people.
True
False
GI ulceration is the primary side effect of NSAIDs in large animals.
True
False
Signs of pain can be classified as physiologic or behavioral. Examples of behavioral signs of pain are
Screaming, escaping, and tucking the abdomen
Tachycardia, dilated pupils, and howling
Biting, hiding, and hypertension
The drug gabapentin has particular efficacy for
Abdominal pain
Deep pain
Neuropathic pain
NMDA-receptor antagonists such as ketamine have a particular place in preventing and treating
Wind-up pain
Preexisting pain
Neuropathic pain
Because of potential side effects of NSAIDs, patients should not receive them if they have
Stomach ulcers
Bleeding abnormalities
Hypotension
All are correct
Dogs receiving NSAIDs are particularly prone to adverse effects relating to the GI system, whereas cats are particularly prone to adverse effects relating to the
Kidneys
Blood
Liver
Cats can be given NSAIDs when indicated but should never be given.
Acetaminophen
Meloxicam
Carprofen
Local anesthetics work by
Inhibiting norepinephrine release
Disrupting neural transmission
Blocking mu receptors
The stinging sensation caused by injection of local anesthetics can be reduced by adding 0.1 mL of __________________ to 10 mL of the local agent.
Sodium bicarbonate
Bupivacaine
Epinephrine
One of the following species is more sensitive to morphine and therefore requires lower doses of this pure agonist. Which one is it?
Cat
Horse
Dog
An opioid that has a significantly longer duration of action than most is
Morphine
Buprenorphine
Hydromorphone
This synthetic drug is available in oral form and produces opioid-like stimulation of the mu receptor, but with fewer side effects.
Fentanyl
Hydromorphone
Tramadol
Which of the following drug combinations is representative of the anesthetic protocol known as “kitty magic”?
Buprenorphine, meloxicam, and dexmedetomidine
Buprenorphine, dexmedetomidine, and ketamine
Fentanyl, ketoprofen, and ketamine
Which of the following drugs is safe for use in patients with GI disturbances and thus is a good choice for dogs with gastric dilation volvulus (GDV), unlike many analgesics.
Hydromorphone
Carprofen
Lidocaine
In view of the efficacy gabapentin has in treating neuropathic pain, which of the following conditions would it be used to treat?
Pain secondary to a severe infection
Limb pain resulting from trauma
Resistance to being touched at a location with no tissue damage
The most commonly used NSAIDs in large animals are
Ketoprofen and phenylbutazone
Phenylbutazone and flunixin meglumine
Flunixin meglumine and carprofen
The opioid most commonly used in large animals is
Morphine
Butorphanol
Fentanyl
The analgesic class most commonly used in horses is
Opioids
NSAIDs
α2-Agonists
