A nurse is caring for a client who is 2 days postoperative following abdominal surgery and has a prescription for opioid analgesia. Which of the following actions should the nurse implement to help facilitate the client's recovery?

A. Naloxone is an opioid antagonist used to reverse opioid-induced respiratory depression. A respiratory rate above 24/min indicates tachypnea, not opioid toxicity, so naloxone would be inappropriate and potentially harmful. B. Administering analgesics before activities such as ambulation, coughing, or deep breathing exercises helps manage pain effectively, promotes participation in postoperative activities, reduces the risk of complications (e.g., atelectasis, pneumonia, or venous thromboembolism), and facilitates recovery. This is a key nursing intervention to support mobility and rehabilitation. C. Opioids typically cause constipation, not loose stools. The nurse should instead provide teaching on preventing constipation through hydration, high-fiber diet, and stool softeners if appropriate. D. Withholding analgesics until pain becomes severe can impair mobility, disrupt sleep, and delay recovery. Opioids should be administered as scheduled or before activity, not only in response to pain, to maintain comfort and support rehabilitation.
