A nurse is assessing a client following abdominal surgery. Which of the following findings should the nurse report to the provider?

A. Urinary output 20 mL/hr: A urinary output less than 30 mL/hr in an adult indicates potential renal hypoperfusion or urinary retention. This is a priority finding that should be reported to the provider promptly. B. Serous drainage on abdominal dressing: Serous drainage is a normal postoperative finding, indicating normal wound healing and fluid exudate. It does not require immediate provider notification. C. Temperature 37.6° C (99.7° F): This temperature is slightly elevated but within the expected postoperative range due to the inflammatory response. It does not indicate an urgent complication. D. Blood pressure 100/70 mm Hg: This blood pressure is within normal limits for many adults and is not necessarily concerning in a postoperative context unless accompanied by other symptoms such as tachycardia or dizziness.
