The major toxicity associated with neuromuscular blocker overdose is: Select one: Explain the mechanism of action of the anesthetic agents nitrous oxide, propofol, and ketamine. Select one: a. Nitrous oxide, propofol, and ketamine antagonize NMDA receptors, thereby blocking cation movement and depolarization while enhancing the opioid mu receptors. b. Nitrous oxide, propofol, and ketamine potentiate NMDA receptors, thereby increasing cation movement and hyperpolarization with no effect on the opioid mu receptors. c. Nitrous oxide, propofol, and ketamine antagonize NMDA receptors, thereby blocking cation movement and depolarization while suppressing the opioid mu receptors. d. None of these are correct.
