What is an effective nonpharmacological intervention for managing acute pain postoperatively?

A. Intravenous antibiotics are used to prevent or treat infection, not to manage pain, so they are not a nonpharmacological intervention. B. Cold application is an effective nonpharmacological method for managing acute postoperative pain. It helps reduce inflammation, swelling, and nerve conduction, providing temporary pain relief without medication. C. Epidural analgesia is a pharmacological intervention, not nonpharmacological, as it involves the administration of anesthetic or opioid agents. D. Acetaminophen administration is a pharmacological intervention; although effective for pain, it does not fall under nonpharmacological strategies.
