Final answer:
Cisatracurium is the neuromuscular blocking agent that does not require dose adjustment in severe hepatic impairment due to its Hoffman elimination. Avermectins inhibit helminth neural transmission, and a muscarinic agonist serves as an antidote to atropine poisoning.
Step-by-step explanation:
The question is focused on identifying the neuromuscular blocking agent that does not require dose adjustment in patients with severe hepatic impairment. Among the given options, cisatracurium does not require dose adjustment for severe hepatic impairment due to its unique Hoffman elimination pathway and organ-independent metabolism. This makes it a viable option for patients with compromised liver function.
In addition, addressing the reference information:
- Drug classes that inhibit neuronal transmission in helminths include avermectins.
- The antidote to atropine poisoning would be a muscarinic agonist.
- Types of drugs with anti-anxiety effects typically include benzodiazepines, SSRIs, and certain beta-blockers, although they are not directly listed in the provided options.
