The client is brought to the emergency department with a reported overdose of morphine. Which drug does the nurse anticipate will be prescribed?

A. Butorphanol Butorphanol is a mixed opioid agonist-antagonist. It has both agonist and antagonist properties at opioid receptors. While it can be used for pain management, it is not commonly used for opioid overdose reversal. B. Naloxone Naloxone is an opioid receptor antagonist and is the drug of choice for reversing opioid overdose, including morphine overdose. It works by competitively binding to opioid receptors, blocking the effects of opioids. C. Flumazenil Flumazenil is a selective antagonist for benzodiazepines. It is used to reverse the effects of benzodiazepine overdose but does not have an effect on opioid overdose. D. Pentazocine Pentazocine is a mixed opioid agonist-antagonist. Like butorphanol, it has both agonist and antagonist properties at opioid receptors. It is used for pain management but is not commonly used for opioid overdose reversal.
