A nurse is monitoring a client following a lumbar laminectomy. The client has a drain and indwelling urinary catheter. The nurse should identify which of the following findings as an indication of a complication of the surgery?

Rationale: A. Oral temperature of 37.2° C (99° F): This is a normal postoperative temperature and does not indicate infection or any other complication. Mild elevations in temperature are expected after surgery. B. Clear drainage on the dressings: Clear drainage, particularly if it is watery and not tinged with blood, may indicate cerebrospinal fluid (CSF) leakage. This is a serious complication of spinal surgery and requires immediate evaluation to prevent infection and further neurological issues. C. Drain output 75 mL in 4 hr: This amount of drainage is within normal limits for the early postoperative period, depending on the surgeon's parameters. It is not inherently concerning unless it becomes excessive or has abnormal characteristics. D. Decreased bowel sounds in all quadrants of the abdomen: Decreased bowel activity is common after surgery due to anesthesia and immobility. It is expected in the immediate postoperative period and not necessarily a sign of a complication unless prolonged.
