A patient is to have surgery and it is planned that atracurium (Tracrium) is to be used as an adjunct to general anesthesia. How will the atracurium work?
A) Act as agonist to acetylcholine
B) Stops depolarization in the axion
C) Act as antagonist to acetylcholine
D) Stops repolarization in the axion
C
Feedback:
Nondepolarizing neuromuscular junction blockers compete with acetylcholine (ACh) for the ACh receptor site and after they occupy the site, stimulation cannot occur. This results in paralysis because the muscle cannot respond. Other options are incorrect.
