What medication treats an opioid overdose?

Ketamine
Naloxone
Hydromorphone

The correct answer is: Naloxone

Naloxone is a medication used to treat an opioid overdose by reversing the effects of the opioid on the body's opioid receptors. This makes it the correct choice among the given options. Ketamine is not used to treat opioid overdoses and may even exacerbate the symptoms. Hydromorphone is an opioid itself and therefore cannot be used to treat an opioid overdose. It also has a longer duration of action compared to naloxone, making it less effective in emergency situations.
