Final answer:
Naloxone is a drug that can reverse an unresponsive state induced by opioid analgesics, by antagonizing the actions of opioids at the receptors and restoring normal breathing. Option C.
Step-by-step explanation:
If a client being given an opioid analgesic is found unresponsive to stimuli, a drug that might be ordered to reverse this state is naloxone.
Naloxone is an opiate antagonist that, when administered to individuals experiencing opioid overdose, can quickly reverse the effects, including respiratory depression. It works by antagonizing the actions of opioids like morphine at all its receptors.
Naloxone is recognized for its ability to restore breathing in patients experiencing an opioid overdose, and it is effective even in reversing the effects of narcotics in newborns whose mothers have received opioids during labor.
Hence, the right answer is option C.
