A build up of chemical mediators within the spinal cord after a painful stimulus is called which of the following?
A. Acute pain B. WInd Up C. Chronic pain D. Neuropathic pain |
B Wind up pain.
Acute pain is the first recognised pain after bodily injury and is self limiting. Chronic = Weeks to months persists beyond expected healing time Neuropathic is pain from injury to the central or peripheral nervous system |
A. Acute pain
B. WInd Up C. Chronic pain D. Neuropathic pain |

After an induction dose of thiopental, recovery usually occurs after 10 - 15 mins. Which of the reasons is why recovery is so fast?
A - redistribution of the drug to muscle and fat. B - Renal excretion in urine C Hepatic metabolism D Tissue absorption of the ionised drug |
A - Redistribution to muscle (most) and fat (small amount). Metabolism is very slow, 10% per hour. Tissue absorption of ionised form does not occur

Which of the following might cattle have during anaesthesia?
1. Copious Salivation 2. Bloat 3. Regurgitation 4. Hypo-ventilation from pressure of the abdomen on the diaphragm. A 1 is correct B 1 & 2 are correct C. 1, 2, & 3 are correct D. All four are correct |
D. All four are correct.
To prevent regurge, place a tube in the oesophagus to direct rumen contents away from the head. Pregnancy or full abdo make breathing difficult. |

The recommended size of a rebreathing bag is:
A. 4.6mL/kg B. 10 to 20mL/kg C. 60mL/kg D. 200mL/kg |
C. 60mL/kg
Most recommend the bag be close to totall chest capacity, which is 5-6 times tidal volume. Tidal volume estimated to be 10mL/kg. |

A yellow colour on a vaporiser indicates it is to be used for which of the following?
A. Halothane B. Isofluorane C. Sevofluorane D. Nitrous Oxide |
C. Sevofluorane.
Halothane is red Isofluorane is purple and Nitrous Oxide is Blue |

In a horse under anaesthesia with a MAP under 60mmHg, what is usually administered if fluid loading ineffective?
A. Epinephrine B. Digoxin C. Esmolol D. Dobutamine |
D. Dobutamine
Epinephrine - cardiac arrest Digoxin - tx heart disease Esmolol - beta blocker used to treat tachycardia. Dobutamine - Beta agonist commonly used to treat hypotension in horses under anaesthesia. |

Which of hte following would be a reasonable induction protocol for an animal with signs of icterus?
A. THiopental followed by halothane B. Ketamine/diazepam followed by halothane C. Propofol followed by isofluorane D. Mask induction with haothane |
C. Propofol followed by isofluorane.
Thiopental not recommended cos slower metabolism of the drug, even though recovery is primarily due to redistribution. Halothane may cause 'halothane hepatitis' Propofol redistributed and metabolised at sites other than the liver. Metabolism of isofluorane is only 0.2% so it is a good choice. |
