Which of the following drugs would most likely be effective to decrease the patient's spontaneous breathing?

Correct Answer: B

Rationale: Vecuronium is a skeletal muscle relaxant that acts as a non-depolarizing neuromuscular blocker, making it effective in decreasing spontaneous breathing by causing muscle relaxation. Diazepam, Botulinum toxin, Dantrolene, and Baclofen do not directly target skeletal muscle function in the same way as Vecuronium. Diazepam is a benzodiazepine, Botulinum toxin is used for muscle spasms, Dantrolene is a muscle relaxant used for malignant hyperthermia, and Baclofen is a muscle relaxant used for spasticity. Therefore, Vecuronium is the most appropriate choice in this scenario.

Correct Answer: C

Rationale: The primary reason for using cisatracurium instead of tubocurarine in this patient is likely due to propofol induction, as cisatracurium is often preferred with propofol due to their compatibility. Liver or renal insufficiency or advanced age would not specifically dictate the choice between cisatracurium and tubocurarine. Diazepam administration is not directly related to the choice between these two neuromuscular blocking agents.
