Quiz on Swine Anesthesia and Analgesia

These questions were kindly donated by Dr. Victoria Hampshire, to whom I am very grateful. She sent a CD of material used by USUHS students to prepare for the board exams in 2000, including outlines of the entire blue book on anesthesia complete with questions.

Write down your answers and then check the answers.

 

Questions:

1.      Which combination of intramuscular anesthetics produces good muscle relaxation and 30 minutes of deep sedation with profound but reversible hemodynamic effects?

  1. Ket-Xyl
  2. Ket-Climazolam
  3. Ket-Ace
  4. Til-Zol
  5. Ket-Medetomidine

  1. Isoflurane
  2. Enflurane
  3. Halothane
  4. Methoxyflurane

 

3.      Alpha-2 adrenergics cause heart rate to increase/decrease and cause a hypotensive/hypertensive state.

 

4.      Which alpha-2 adrenergics provide analgesia?

  1. xylazine
  2. detomidine
  3. medetomidine
  4. atipamezole
  5. all of the above
  6. a & c

 

5.      Which of these breeds are susceptible to malignant hyperthermia?

  1. Yorkshire
  2. Sinclair
  3. Hormel
  4. Goettingen
  5. All of the above

 

6.      Which statement is not true regarding the pathophysiology of MH?

  1. massive influx of calcium into the cell.
  2. Transmitted as an autosomal dominant Hal genotype
  3. Due to a C to T defect at nucleotide 1843
  4. Related to the calcium release channel at ryr-1 locus
  5. All of the above are true

 

7.      The first cardinal sign of MH is?

  1. an increase in body temperature
  2. an increase in HR and RR
  3. an increase in PaCO2
  4. an elevation in end tidal CO2
  5. a severe rhabdomyolysis

8.      Coronary steal is described as:

  1. a band of fibrous tissue that circle the heart
  2. atrophy of heart musculature
  3. a shunting of blood away from ischemic areas
  4. collateral circulation which allows for perfusion of collateral dependent areas

 

9.      MAC stands for?  What units is it expressed in?

 

10.  Which inhalant has the highest MAC?

  1. halothane
  2. isoflurane
  3. nitrous oxide

11.  Why should nitrous never be used as a sole anesthetic agent?

  1. high abuse potential
  2. low solubility
  3. low potency
  4. cardiovascular depression

  5. all of the above

 

13.  Which of the following statements regarding intraoperative ECG monitoring for swine is FALSE?

  1. ECG monitors the adequacy of circulatory function
  2. Swine have a prolonged Q-T interval
  3. Use of bretylium every 30 min will reduce cardiac arrhythmias
  4. Miniature swine are less susceptible to cardiac arrhythmias
  5. A heart rate below 70 is considered bradycardia

 

14.  Which parameter is not recommended for monitoring anesthetic depth?
