The nurse is caring for a patient who returned 4 hours ago from having a lumbar laminectomy. Which change in assessment requires further action?

Clear yellow drainage from the Foley catheter is a normal finding postoperatively. Not having a bowel movement immediately after surgery is not unusual due to anesthesia and postoperative medications. Bowel function should be monitored. Numbness in both feet could indicate nerve injury, spinal cord compression, or other complications such as hematoma formation, and requires immediate attention. Pain is expected after surgery, but if the pain level is not well-controlled, it should be addressed. A pain score of 7/10 requires further assessment, but it is not as urgent as bilateral numbness.
