In the postanesthesia care unit, which client is likely to require immediate treatment with naloxone?

The selection of this particular client for immediate treatment with naloxone is based on the presence of symptoms indicative of an opioid overdose. Naloxone is an opioid antagonist used to rapidly reverse the effects of opioid overdose, making it a critical intervention in cases where a client exhibits respiratory depression, decreased level of consciousness, or other signs of opioid toxicity.

In the context of a postanesthesia care unit, clients who have received opioid pain medications during their surgical procedure are at risk for complications related to those drugs. If this client demonstrates significant respiratory distress or altered mental status shortly after surgery, naloxone would be necessary to quickly restore normal respiratory function and consciousness. This is especially relevant if there are no other identifiable causes for their deterioration in condition.

Moreover, clients who have not been administered opioids or who demonstrate appropriate postoperative recovery signs would not warrant immediate naloxone treatment. Therefore, focusing on a client showing clear and acute signs of opioid involvement confirms the need for immediate administration of naloxone to prevent further complications.
