A nurse is caring for a client who is two hours postoperative following a cholecystectomy and reports pain. Which of the following actions should the nurse take? (Select all that apply.)

A. Offer the client a back rub: A back rub can help alleviate mild discomfort and promote relaxation, which can be soothing for the client after surgery. B. Assist the client to ambulate: While ambulation can help with gas pain in a laparoscopic cholecystectomy, immediately post-op (2 hours) and if the client is reporting significant pain, forcing ambulation might be too early and increase discomfort. C. Remind the client to use incisional splinting: Incisional splinting is helpful for minimizing pain during coughing or movement. Reminding the client to use it is important for comfort and preventing strain on the incision. D. Change the client's position: Changing the client's position can help alleviate discomfort by relieving pressure on specific areas of the body and promoting better circulation. E. Identify the client's pain level: Assessing the client's pain level is critical to understanding the extent of discomfort and providing appropriate pain management interventions.
