Anesthesia Exam 1 with questions and
answers 100%Correctly verified answers
latest update 2025/2026 RATED A+
Anesthesia Definition - CORRECT ANSWERS Loss of sensation to all or part of the body
Analgesia Definition - CORRECT ANSWERS Without pain
What are the components of general anesthesia? - CORRECT ANSWERS • Animal is
unconscious and unaware of its surroundings
• Unconsciousness (hypnosis, narcosis)
• Muscle relaxation
• Lack of pain (analgesia)
• Loss of memory (amnesia)
• Suppression of reflexes (motor, autonomic)
• All without harming the patient
What are the general principles of veterinary anesthesia? - CORRECT ANSWERS • Physiology,
pharmacology, and pathology are building blocks for the science behind anesthesia
• Adequate standard of monitoring
• Additional requirements
○ Species differences in anatomy, pharmacologic effects, and metabolism of drugs
○ Humane treatment-prevention of pain, relief from anxiety and stress, sympathetic handling
○ Prevention of injury to animal and personnel
• Critical evaluation of history, physical examination, and laboratory data -> know your patient
• Stabilize and correct identified abnormalities, if possible, prior to anesthesia
• Be organized and efficient to minimize anesthesia time
,• Select anesthetic protocol based on patient, existing abnormalities and to minimize adverse effects
• Identify and prepare for potential complications and underlying pathologies
• Establish intravenous access whenever possible
• Secure and maintain patent airway
• Use supplemental oxygen when indicated and provide ventilatory support
• Monitor vital body systems (cardiovascular, respiratory, and CNS)
• Identify and correct abnormalities that arise
• Continue monitoring and support through recovery period
• Use appropriate analgesia and sedation to minimize pain and distress
Why is pre-anesthetic patient evaluation important? - CORRECT ANSWERS • Identifies
individual risk factors
• Underlying physiologic abnormalities
Contributes information for development of an individualized anesthetic plan
Pre-Anesthetic Fasting Requirements and Consequences for Inadequate Fasting for Cats and Dogs -
CORRECT ANSWERS ○ 6-12 hours fast
○ Free access to water up until procedure (1 hour before)
○ Fast about 4 hours up to 4 months of age - risk of hypoglycemia
○ Decreases risk of regurgitation and aspiration
Pre-Anesthetic Fasting Requirements and Consequences for Inadequate Fasting for Horses - CORRECT
ANSWERS ○ 6-12 hour fast
○ Access to water
, ○ The weight of GI contents increases pressure on diaphragm and limits lung expansion -> decreased
ventilation results in decreased arterial oxygen and increased arterial carbon dioxide levels ->
ventilation-perfusion mismatch
Pre-Anesthetic Fasting Requirements and Consequences for Inadequate Fasting for Cattle - CORRECT
ANSWERS ○ 24-48 hours food
○ 12-24 hours water
○ Regurgitation and aspiration of rumen contents
Bloat -> pressure on diaphragm, limits lung expansion -> decreased ventilation results in decreased
arterial oxygen and increased arterial carbon dioxide levels -> ventilation-perfusion mismatch
Pre-Anesthetic Fasting Requirements and Consequences for Inadequate Fasting for Sheep and Goats -
CORRECT ANSWERS ○ 12-24 hours food
○ +/- water
○ Ruminants less than 4 weeks fast only 2-4 hours, nursing, monogastric, less prone to regurgitation
○ Regurgitation and aspiration of rumen contents
○ Bloat -> pressure on diaphragm, limits lung expansion -> decreased ventilation results in decreased
arterial oxygen and increased arterial carbon dioxide levels -> ventilation-perfusion mismatch
Why are fasting recommendations different for pediatric patients? - CORRECT ANSWERS • Due
to the risk of hypoglycemia, their livers are not fully developed yet and therefore they cannot regulate
their blood-glucose
What type of drug is Maropitant? Explain its use as a peri-operative medication. - CORRECT ANSWERS
• Neurokinin-1 antagonist
• Give 1.0 mg/kg subQ at least one hours before opioid premedication to prevent vomiting and signs of
nausea associated with opioid drugs
• Also provides adjunct analgesia
• Faster return to feeding post-operatively
, What are the general steps of anesthesia? - CORRECT ANSWERS • Pre-anesthetic evaluation
• Premedication period
• Induction of anesthesia
• Maintenance
• Recovery
• Post-anesthetic period
What are the components of the pre-anesthetic minimum data base? - CORRECT ANSWERS
Signalment
History
Physical exam
Laboratory and diagnostic tests
What does signalment consist of? - CORRECT ANSWERS Species
Breed
Age
Sex/neuter status
Temperament
Weight and body condition score
What are the specific breed related anesthetic issues presented in lecture? - CORRECT ANSWERS
• Brachycephalic breeds more prone to upper airway obstruction
• Greyhounds and drug metabolism
• Breed disposition to cardiac disease (Cavalier, Maine coon)
• Poland China, Landrace, Duroc pigs, and malignant hyperthermia
