Final answer:
Naloxone (Narcan) is the reversal agent for an opiate overdose, not Epinephrine. It is administered intranasally at a dose of 2mg to effectively reverse respiratory depression caused by opioid overdose.
Step-by-step explanation:
The reversal agent for an opiate overdose is Naloxone (Narcan), which can be administered intranasally at a dose of 2mg. Naloxone works by antagonizing the effects of opioids such as opium, heroin, fentanyl, morphine, oxycodone, and various prescription pain relievers. It effectively reverses the life-threatening respiratory depression caused by opioid overdose by competing for the same receptor sites in the brain. Unlike Naltrexone, Naloxone has a short duration of action and is typically given via parenteral routes. Epinephrine (Epi) 1 mg IVP is not used for opioid overdose reversal; it is primarily used in cases of severe allergic reactions (anaphylaxis) or cardiac arrest.
Therefore, the correct answer to the question "Reversal agent for Opiate OD are" is A) narcan IN 2mg.
