Final answer:
The nurse would anticipate the prescription of Naloxone (Narcan) for a patient who has overdosed on morphine, as it is an opiate antagonist designed to reverse opioid effects, including respiratory depression.
Step-by-step explanation:
In the case of a patient brought to the emergency department with a reported overdose of morphine, the drug that a nurse would anticipate being prescribed is Naloxone (Narcan). Naloxone is an opiate antagonist, which means it can rapidly reverse the effects of opioids like morphine, heroin, oxycodone, and others. This drug works by binding to opioid receptors in the brain, thus blocking the effects of the opioid and effectively reversing the respiratory depression that is often the cause of overdose deaths.
While other medications, such as Butorphanol (Stadol), Pentazocine (Talwin), and Flumazenil (Romazicon) have their own uses in different contexts, Naloxone is specifically used for acute narcotic overdose situations due to opioids. Flumazenil (Romazicon), for example, is an antidote for benzodiazepine overdose, and is not effective against opioids like morphine.
