A 25 year old woman present to the emergency room with decrease reflexes, hypoventilation, hypotension, and fuced pupils, a family member who is accompanying the patient has bottle of diazepam which the label states was recently the family member also indicates that the patient has a depression. What intervention should the nurse expect to administer?
Explanation
Core Concept: Reversal of opioid toxicity. The clinical picture of hypoventilation, hypotension, and pinpoint (or fixed/fuced) pupils is the classic opioid toxidrome, for which Naloxone is the specific antidote. (Note: While diazepam is mentioned, benzodiazepine overdose typically presents with normal pupils; the presence of pinpoint pupils and severe respiratory depression strongly indicates an opioid co-ingestion requiring Naloxone).
Clinical Presentation: Opioid overdose presents with CNS depression, severe respiratory depression (hypoventilation), miosis (pinpoint pupils), hypotension, and decreased bowel sounds.
Diagnosis: Clinical diagnosis based on the classic toxidrome and history. First-line diagnostic steps include immediate ABC assessment, pulse oximetry, arterial blood gas (ABG), and a urine drug screen.
Management: Acute management prioritizes airway and breathing support. Administer IV Naloxone immediately to reverse respiratory depression. Long-term definitive management involves addiction medicine referral, counseling, and medication-assisted treatment (e.g., buprenorphine).
