FALSE

Question 19

T/F:

Methocarbamol is a carbamate of guaifenesin that gets metabolized to guaifenesin

T/F:

Thiopental and Physostigmine are agonists of Guaifenesin

Answer 23

FALSE

Physostigmine is an antagonist of Guaifenesin

Question 24

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

Question 25

T/F:

Since dogs and ruminants lack pseudocholinesterase,

depolarizing non-competitive neuromuscular blockers last about
