Final answer:
A nurse assessing a client who is receiving morphine via IV bolus and is exhibiting a respiratory rate of 8 breaths per minute is observing signs of opioid-induced respiratory depression. In this scenario, the appropriate medication to administer would be Naloxone (Option A).
Step-by-step explanation:
The appropriate medication for a client exhibiting signs of opioid-induced respiratory depression from morphine is Naloxone, an opiate antagonist that reverses the effects of opioids.
This drug acts as an opiate antagonist, meaning it quickly reverses the effects of opioids such as morphine, which include pain relief or analgesia, euphoria, and potential respiratory depression in high doses.
Naloxone rapidly restores normal respiration by displacing opioids from the receptors they have bound to in the brain.
It is particularly useful in acute situations to counteract life-threatening depression of the central nervous system and respiratory system.
Hence, the correct answer is Option A.
