A nurse is caring for a client who is experiencing respiratory depression after taking an excessive dose of oxycodone. Which of the following medications should the nurse expect to administer?

Choice A rationale Naloxone is an opioid antagonist that rapidly reverses the effects of opioid overdose, including respiratory depression. It binds to opioid receptors and displaces the opioid molecules, reversing their effects. Choice B rationale Bisacodyl is a stimulant laxative used to treat constipation. It does not have any effect on opioid-induced respiratory depression. Choice C rationale Flumazenil is a benzodiazepine antagonist used to reverse the effects of benzodiazepines, not opioids. It is not effective in treating opioid-induced respiratory depression. Choice D rationale Pentazocine is an opioid agonist-antagonist used for pain relief. It does not reverse opioid-induced respiratory depression and can potentially worsen the condition.
