A nurse in an emergency department is caring for a client who is experiencing a morphine overdose. Which of the following medications should the nurse anticipate administering to the client?

Rationale: A. Disulfiram: Disulfiram is used to support alcohol abstinence by causing unpleasant reactions when alcohol is consumed. It does not reverse opioid overdose and is not indicated for morphine toxicity. B. Naloxone: Naloxone is an opioid antagonist that binds to opioid receptors and rapidly reverses the effects of morphine and other opioids. It is the first-line treatment for opioid overdose, effectively restoring respiratory function and alertness. C. Activated charcoal: Activated charcoal can adsorb certain ingested toxins in the gastrointestinal tract, but it is not effective for opioids already absorbed systemically, such as in a morphine overdose. D. Flumaren: Flumazenil (Flumaren) is a benzodiazepine antagonist used to reverse benzodiazepine overdose, not opioid toxicity. It has no effect on morphine or other opioids.
