Final answer:
The correct answer is option C) Cisatracurium and Atracurium as the benzylisoquinolinium NMBAs listed. Avermectins inhibit neuronal transmission in helminths, and a muscarinic agonist would serve as an antidote to atropine poisoning. Anxiolytics have anti-anxiety effects.
Step-by-step explanation:
The benzylisoquinolinium neuromuscular blocking agents (NMBAs) are a group of medications used to cause temporary paralysis by blocking the communication between nerves and muscles. The options provided do not include benzylisoquinolinium derivatives. However, to clarify, common benzylisoquinolinium NMBAs include Atracurium and Cisatracurium. Therefore, the correct answer to the question, 'Name the Benzylisoquinolinium NMBA's,' would be option C) Cisatracurium and Atracurium.
Turning to the additional question regarding the inhibition of neuronal transmission in helminths, the correct class of drugs is avermectins (option B).
As for the antidote to atropine poisoning, a muscarinic agonist would be the type of drug used (option C). Atropine poisoning results in the blockage of muscarinic acetylcholine receptors, and one way to counteract this effect is by administering a muscarinic agonist, which would activate the blocked receptors.
Lastly, drugs that would have anti-anxiety effects typically fall under the category of anxiolytics, although the options presented do not specify this class directly. Benzodiazepines and SSRIs are common examples of anxiolytics.
