1.
A dog undergoing prolonged abdominal surgery develops progressive
hypotension despite an adequate anesthetic depth. Which intervention should
the anesthesia technician prioritize first?
A. Increase the inhalant anesthetic concentration
B. Assess anesthetic depth, heart rate, ventilation, and circulating volume
C. Administer additional opioid immediately
D. Increase the fresh gas flow only
Answer: B
Rationale: Hypotension under anesthesia has multiple possible causes, including
excessive anesthetic depth, hypovolemia, vasodilation, bradycardia, and cardiac
dysfunction. A systematic assessment should occur before selecting a specific
treatment.
2.
Which monitoring parameter provides the most direct information about a
patient's ventilatory effectiveness during general anesthesia?
A. Pulse rate
B. Mean arterial pressure
C. End-tidal carbon dioxide
D. Peripheral temperature
Answer: C
,Rationale: End-tidal CO₂ provides continuous information about alveolar
ventilation and is particularly useful for detecting hypoventilation, apnea, and
changes in pulmonary perfusion.
3.
A mechanically ventilated patient suddenly develops a substantial increase in
peak inspiratory pressure. Which problem should be investigated first?
A. Excessive anesthetic depth
B. Airway obstruction or decreased pulmonary compliance
C. Hypoglycemia
D. Peripheral vasodilation
Answer: B
Rationale: An acute increase in airway pressure commonly indicates obstruction,
bronchoconstriction, kinked tubing, mucus accumulation, endotracheal tube
problems, or reduced pulmonary/thoracic compliance.
4.
Which opioid is generally considered a full μ-opioid receptor agonist and
therefore capable of producing substantial analgesia?
A. Butorphanol
B. Buprenorphine
C. Morphine
D. Naloxone
Answer: C
Rationale: Morphine is a full μ-opioid agonist. Butorphanol has primarily κ-agonist
and μ-antagonist activity, while buprenorphine is a partial μ agonist and naloxone
is an opioid antagonist.
,5.
Why is multimodal analgesia particularly valuable for patients undergoing major
orthopedic procedures?
A. It eliminates the need for monitoring
B. It combines analgesic techniques acting through different mechanisms
C. It prevents all postoperative complications
D. It guarantees complete anesthesia without inhalants
Answer: B
Rationale: Multimodal analgesia combines drugs and techniques with different
mechanisms, potentially improving analgesia while reducing reliance on any single
drug and decreasing dose-related adverse effects.
6.
A cat becomes bradycardic and hypotensive during anesthesia. Which drug class
may be considered when clinically significant vagally mediated bradycardia is
suspected?
A. Anticholinergic
B. Benzodiazepine
C. α₂ antagonist
D. Local anesthetic
Answer: A
Rationale: Anticholinergic drugs such as atropine or glycopyrrolate reduce
parasympathetic influence on the heart and may increase heart rate when vagal
bradycardia is clinically significant.
, 7.
Which local anesthetic complication represents a potentially life-threatening
systemic toxicity syndrome?
A. Local tissue numbness
B. Local anesthetic systemic toxicity
C. Mild injection discomfort
D. Temporary vasodilation
Answer: B
Rationale: Excessive systemic exposure to local anesthetics can cause neurologic
and cardiovascular toxicity, including seizures, arrhythmias, cardiovascular
depression, and potentially cardiac arrest.
8.
A patient receiving an inhalant anesthetic suddenly develops absent capnographic
waveforms. What should the technician evaluate immediately?
A. Body temperature only
B. The patient's airway, breathing circuit, and ventilation
C. Blood glucose only
D. Urine specific gravity
Answer: B
Rationale: Loss of a capnogram can result from apnea, disconnection, accidental
extubation, airway obstruction, equipment malfunction, or severe changes in
pulmonary blood flow. Immediate airway and equipment assessment is essential.
