A patient has been on opioid therapy, Oxycodone (Roxicodone) 15 mg po three times daily, for chronic back pain for the last 10 years. They are brought into the emergency department with altered mental status. Their partner reports they were recently diagnosed with early dementia and stopped eating in the last 48 hours. Their partner is worried they took too many doses of oxycodone. Upon exam, the patient is showing signs of respiratory depression. What should the Nurse Practitioner do FIRST?

A. Order stat naloxone intravenously to reverse the opioids: The patient is exhibiting respiratory depression, which represents an immediate life-threatening opioid toxicity. Naloxone rapidly displaces opioids from mu-receptors, reversing respiratory and central nervous system depression. Airway and breathing stabilization take absolute priority over all other interventions. B. Order intravenous fluids for likely dehydration: Dehydration may be contributing to altered mental status, especially after poor oral intake, but it does not address respiratory depression. Fluids do not reverse opioid-induced hypoventilation. This intervention is secondary once airway and breathing are stabilized. C. Order buprenorphine for opioid use disorder treatment: Buprenorphine is used for long-term management of opioid use disorder and is not appropriate in an acute overdose setting. Initiating it during active opioid toxicity can precipitate withdrawal. Acute stabilization must occur before considering maintenance therapy. D. Hold all opioid medications until his mentation is back to baseline: Holding opioids may prevent further exposure but does not reverse the opioid already causing respiratory depression. Passive withholding is insufficient in a patient with active hypoventilation. Immediate pharmacologic reversal is required to prevent hypoxic injury.
