Acepromazine has many different sedative properties and other dose-dependent side effects. What is the most common side effect seen?
Vasodilation
Hypoventilation
An increase in body temperature
Cardiac arrhythmias
 
Which anaesthetic drug was found to increase the risk of anaesthesia morbidity and mortality in the CEPSAF study?
Acepromazine
Medetomidine
Propofol
No drug was found to increase the risk
 
Many injectable anaesthetic agents and sedatives act within the central nervous system (CNS). How are nerve impulses and messages communicated through the CNS?
Neuromodulation
Neurotransmitters
Schwann Cells
Neuromuscular Junctions
 
What does “co-induction” of anaesthesia mean?
When a patient is heavily sedated intramuscularly and then intubated
When a mask induction technique is used
When an animal has multiple anaesthetics in daily succession
When anaesthesia is induced with more than one drug
 
When discussing Minimum Alveolar Concentration (MAC), what is the best description of the concept of “MAC-sparing”?
The percentage on the vaporiser is incorrect due to cold room temperatures
A reduction in MAC due to certain anaesthesia drugs administered
More volatile agent is delivered when using nitrous oxide and oxygen
Varied uptake of the volatile agent in animals with pulmonary disease
 
What neurotransmitter is the principal excitatory neurotransmitter in the vertebrate CNS?
Noradrenaline
Glutamate
Dopamine
Serotonin
 
When using a benzodiazepine as a co-induction drug, how can excitement be avoided?
Avoid premedication with medetomidine
Give ¼ of the induction agent first, then the benzodiazepine
Give the benzodiazepine after the full dose of the induction agent
Dilute the benzodiazepine in 50:50 saline and give it slowly
 
Medetomidine has a biphasic effect on the cardiovascular system. How long does the first phase roughly last?
5 minutes
10 minutes
20 minutes
30 minutes
 
Which induction drug can be given intramuscularly?
Propofol
Alfaxalone
Diazepam
None of the above
 
Which anticholinergic is useful to increase the heart rate in a non-emergent situation e.g vagally mediated bradycardia that is not life threatening?
Glycopyrrolate
Atropine
Dopamine
Noradrenaline
