Question

Which non-depolarizing NMBD has an onset time closest to succinylcholine?

1) Rocuronium
2) Vecuronium
3) Atracurium
4) Cisatracurium

Answer 1

Rocuronium is the non-depolarizing neuromuscular blocking drug (NMBD) with an onset time closest to succinylcholine.

Step-by-step explanation:

Among the given options, the non-depolarizing neuromuscular blocking drug (NMBD) with an onset time closest to succinylcholine is rocuronium.

Rocuronium is an intermediate-acting NMBD and has a rapid onset of action, similar to succinylcholine. It is commonly used for rapid sequence induction and intubation in anesthesia.

Other non-depolarizing NMBDs like vecuronium, atracurium, and cisatracurium have slower onset times compared to succinylcholine.
