A 78-year-old patient is in the recovery room after having a lengthy surgery on his hip. As he is gradually awakening, he requests pain medication. Within 10 minutes after receiving a dose of morphine sulfate, he is very lethargic and his respirations are shallow, with a rate of 7 breaths/minute. The nurse prepares for which priority action at this time?

Choice A reason: Immediate intubation is premature without first reversing opioid-induced respiratory depression with naloxone. Morphine’s rapid onset of lethargy and shallow breathing (7 breaths/min) indicates overdose, reversible by naloxone. Intubation is invasive and reserved for non-responsive cases, risking unnecessary complications when reversal is feasible, delaying targeted treatment in this acute scenario. Choice B reason: Administering naloxone is the priority for opioid overdose, as evidenced by lethargy and respiratory depression (7 breaths/min) post-morphine. Naloxone, an opioid antagonist, rapidly reverses these life-threatening effects, restoring breathing and consciousness. Prompt administration is critical in older adults, who are more sensitive to opioids, ensuring patient safety and preventing hypoxia or death. Choice C reason: Observing for opioid tolerance is inappropriate in this acute situation. Lethargy and shallow breathing indicate overdose, not tolerance, requiring immediate naloxone. Monitoring tolerance delays critical intervention, risking prolonged hypoxia, brain damage, or death, especially in an elderly patient with increased opioid sensitivity post-surgery, where respiratory depression is life-threatening. Choice D reason: Assessing pain level is irrelevant when the patient exhibits opioid overdose symptoms like lethargy and respiratory depression. Pain assessment is secondary to reversing life-threatening respiratory compromise with naloxone. Delaying intervention for pain evaluation risks patient deterioration, as immediate action is needed to restore breathing and stabilize the patient post-morphine administration.
