Which finding should a nurse report to the provider following abdominal surgery?

The presence of yellow-green drainage on the surgical incision is a significant finding that should be reported to the provider. This type of drainage can indicate an infection or other complication at the surgical site, which may require intervention. Surgical incisions typically produce minimal drainage, and if drainage is present, it should be clear or serous in appearance. Yellow-green drainage suggests the possibility of purulent material, possibly due to infection, and needs to be evaluated promptly to prevent further complications.

In contrast, a blood pressure of 102/66 mm Hg is relatively stable and may be considered acceptable post-surgery, especially if the patient is alert and stable. Similarly, straw-colored urine from an indwelling catheter generally indicates normal hydration and kidney function, which does not usually warrant immediate reporting. A respiratory rate of 18/min is within the normal range and indicates adequate ventilation following surgery, making it an observation not requiring urgent attention.
