Examination in Analgesia & Anesthesia
– 100 Practice Questions and Correct
Answers With Rationales 2026 Q&A
1. Which of the following is the most accurate method for assessing
anesthetic depth in dogs?
A. Heart rate
B. Respiratory rate
C. Palpebral reflex
D. Blood pressure
Answer: Palpebral reflex
Rationale: The palpebral reflex is a reliable indicator of anesthetic
depth because it diminishes as anesthesia deepens, more so than
heart or respiratory rate.
2. Which opioid is classified as a pure mu agonist?
A. Butorphanol
, B. Buprenorphine
C. Morphine
D. Nalbuphine
Answer: Morphine
Rationale: Morphine is a pure mu opioid agonist, providing strong
analgesia by binding to mu receptors.
3. What is the primary purpose of premedication in anesthesia?
A. Increase heart rate
B. Cause muscle spasms
C. Reduce anxiety and improve analgesia
D. Decrease anesthetic absorption
Answer: Reduce anxiety and improve analgesia
Rationale: Premedications calm patients, reduce anesthetic
requirements, and provide analgesia before surgical stimulation.
4. Which of the following is a common adverse effect of alpha-2
agonists?
A. Hypertension
B. Bradycardia
C. Hyperthermia
D. Hypoglycemia
Answer: Bradycardia
Rationale: Alpha-2 agonists decrease sympathetic tone, commonly
, causing bradycardia and initial hypertension followed by
hypotension.
5. Which inhalant anesthetic has the lowest blood/gas partition
coefficient?
A. Halothane
B. Isoflurane
C. Sevoflurane
D. Desflurane
Answer: Desflurane
Rationale: Desflurane has the lowest blood/gas solubility, leading to
rapid induction and recovery.
6. The MAC (minimum alveolar concentration) of an inhalant anesthetic
indicates:
A. The analgesic potency
B. The concentration preventing movement in 50% of patients
C. Cardiovascular stability
D. Respiratory depression potential
Answer: The concentration preventing movement in 50% of patients
Rationale: MAC is used to compare anesthetic potency; lower MAC
indicates higher potency.
7. Which of the following reduces the risk of hypotension during
anesthesia?
A. Overhydration
, B. Hypothermia
C. Preoperative fluid therapy
D. Excessive opioid administration
Answer: Preoperative fluid therapy
Rationale: Maintaining adequate intravascular volume helps prevent
hypotension during anesthesia.
8. Which monitoring parameter is most sensitive for early hypoxemia in
anesthetized patients?
A. Heart rate
B. Pulse oximetry (SpO2)
C. Blood pressure
D. Capnography
Answer: Pulse oximetry (SpO2)
Rationale: Pulse oximetry detects oxygen saturation declines earlier
than changes in heart rate or blood pressure.
9. Which drug is commonly used to reverse benzodiazepine sedation?
A. Naloxone
B. Atipamezole
C. Flumazenil
D. Yohimbine
Answer: Flumazenil
Rationale: Flumazenil competitively inhibits benzodiazepine
receptors to reverse sedation and muscle relaxation.
