Enroute to the hospital, morphine is administered for pain control. Upon arrival, the patient rapidly develops respiratory failure and requires intubation and mechanical ventilation. She is administered pancuronium in preparation for intubation but suddenly develops severe bronchospasm and wheezing. Her blood pressure also quickly falls from 12080 mm Hg to 10060 mm Hg. Which of the following best explains the most likely etiology of this complication?? A: Autonomic stimulation, B: Drug interaction, C: Histamine release, D: Skeletal muscle paralysis, E: Underlying neuromuscular disease,  <response>: This is a clinical vignette describing a 62-year-old woman who was involved in a roadside accident and sustained severe chest trauma. She was given morphine for pain control and later developed respiratory failure requiring intubation. After being given pancuronium to facilitate intubation, she developed bronchospasm, wheezing, and hypotension. The question asks to identify the most likely cause of this complication. Based on the sequence of events, it appears that the patient had an adverse reaction after being given pancuronium. Pancuronium is a neuromuscular blocking agent that can trigger histamine release and lead to bronchospasm and hypotension. Therefore, the most likely explanation is histamine release caused by pancuronium administration.C: Histamine release
