A nurse is caring for a client who had abdominal surgery 24 hr ago. Which of the following actions is the nurse's priority?

A. Assessing fluid intake every 24 hr is important for a postoperative client, but it is not the priority action. The nurse should monitor fluid intake and output more frequently, such as every 8 hr or every shift, to detect any imbalances or complications. B. Ambulating three times a day is beneficial for a postoperative client, but it is not the priority action. The nurse should encourage early and frequent ambulation to promote circulation, prevent thromboembolism, and enhance bowel function, but only after ensuring that the client is stable and has adequate pain control. C. Assisting with deep breathing and coughing is the priority action for a postoperative client who had abdominal surgery. The nurse should help the client perform these exercises every 1 to 2 hr to prevent atelectasis, pneumonia, and respiratory failure, which are common and serious complications after abdominal surgery. D. Monitoring the incision site for findings of infection is important for a postoperative client, but it is not the priority action. The nurse should inspect the wound for signs of infection, such as redness, swelling, warmth, drainage, or odor, but this can be done during routine dressing changes or as needed.
