A Patient Who Has a Long-Term Addiction to Opioids Takes

A patient who has a long-term addiction to opioids takes an overdose of barbiturates. The nurse preparing to care for this patient will anticipate:

A) a severe abstinence syndrome when the effects of the barbiturates are reversed.
B) minimal respiratory depression, because the patient has developed a tolerance to opioids.
C) observing pinpoint pupils, respiratory depression, and possibly coma in this patient.
D) using naloxone [Narcan] to reverse the effects of the barbiturates, because cross-tolerance is likely.
