A nurse is caring for a client who is postoperative and develops respiratory depression after receiving morphine for pain control. Which of the following medications should the nurse expect the provider to prescribe?

Rationale: A. Flumazenil: Flumazenil is used to reverse the effects of benzodiazepines, not opioids like morphine. It would not be effective in this situation since the client is experiencing respiratory depression due to morphine use. B. Diphenhydramine: Diphenhydramine is an antihistamine, and while it may help with symptoms like itching, it does not reverse respiratory depression caused by opioids. It is not appropriate for this scenario. C. Naloxone: Naloxone is an opioid antagonist used to reverse the effects of opioid overdose, including respiratory depression. It is the appropriate medication to administer in this situation to quickly reverse the respiratory depression caused by morphine. D. Calcium gluconate: Calcium gluconate is used to treat calcium channel blocker overdose or certain types of hyperkalemia, but it is not effective for reversing respiratory depression caused by opioids.
