Which drug can be used to treat malignant hypothermia?
Dantrolene
Which of the following crosses the BBB?
Scopalamine
Physostigmine
Pyridostigmine
Scopalamine and Physostigmine cross the BBB
When Edrophonium, a reversible acetylcholinesterase is given to a patient
that is suspected of having myasthenia gravis, and the symptoms worsen
the patient was going through
a cholinergic crisis
Which will NOT cause systemic effects?
Pilocarpine
Physostigmine
Demecarium

Pilocarpine
What is the correct order of onset of blockade due to
neuromuscular blockers?
- Tail and Face
- Limb
- Following
- Abdominal
- Intercostal mm.
- Diaphragm mm.
Which drug can cause malignant hyperthermia in susceptible animals?
Succinylcholine
Which 2 drugs can increase intraocular pressure?
Succinylcholine and Scopalamine
M3 selective muscarinic agonist used to treat bladder paralysis by
contracting the detrusor muscle
Bethanecol
Alpha-agonist and is also a Beta-1 agonist at high doses,
Causes vasoconstriction, increased BP, and increased afterload
Norepinephrine
At what dose of dopamine would you see the drug affecting alpha-1 receptors
and causing vasoconstriction?
HIGH doses
Which animal experiences the following adverse effect when given Atropine?
Hypersalivation
Cats
Which animal experiences the following adverse effect when given Atropine?
Cyclopegia panic
Horses
Which animal experiences the following adverse effect when given Atropine?
Sticky saliva
Ruminants
Which animal experiences the following adverse effect when given Atropine?
Breaks down atropine very fast
Rabbits
What drugs are in the “Triple Drip”?
Guaifenesin, Ketamine, and _________
(either Xylazine or Detomidine)
T/F:
Guaifenesin produces analgesia
FALSE
T/F:
Methocarbamol is a carbamate of guaifenesin that gets metabolized to guaifenesin
FALSE
While it IS a carbamate of guaifenesin, it DOES NOT get metabolized to it
Treatment for strychnine, metaldehyde, tetanus, and permethrin poisoning
Methocarbamol
Muscle relaxer that treats functional urethral obstruction and has a
peripheral site of action
Dantrolene
What are the 3 non-depolarizing competitive neuromuscular blockers?
Atracurium, Vecurium, Mivacurium
T/F:
Thiopental and Physostigmine are agonists of Guaifenesin
FALSE
Physostigmine is an antagonist of Guaifenesin
T/F:
In phase 1 of depolarizing neuromuscular blockers,
activation of nicotinic ACh receptors induces prolonged depolarization
at the motor-end plate, and
non-complete repolarization prevents stimulation by ACh
TRUE
T/F:
Since dogs and ruminants lack pseudocholinesterase,
depolarizing non-competitive neuromuscular blockers last about
20 minutes instead of the normal 2-3 minutes in other patients
TRUE
