After administering naloxone, which elements should you monitor?

• A. Airway, breathing, circulation; reassess mental status; prepare for possible airway support
• B. Monitor only heart rate
• C. Check blood glucose only
• D. No monitoring needed after naloxone

Answer: (A)

Protecting the airway and watching the patient’s ventilation and circulation is essential after naloxone. Naloxone reverses opioid-induced respiratory depression, but its effect can wear off before the opioid’s does, so breathing can worsen again. So you continuously assess airway patency and adequacy of breathing (rate, effort, oxygen saturation) and keep an eye on circulation (heart rate, blood pressure). Reassessing mental status is also important because improvement, agitation, or withdrawal symptoms guides further care and potential additional dosing. Be ready to provide airway support if needed (oxygen, suction, bag-valve-mask, or advanced airway). This approach, rather than focusing on a single parameter or assuming no monitoring is required, keeps the patient safe as the effects of opioids wear off.
