A nurse is caring for a child who is postoperative following surgical removal of a Wilms' tumor. Which of the following assessments sacation.co continue NPO status?

A. Passing flatus every 30 minutes indicates bowel activity and suggests that the child may be able to resume oral intake. B. Absent bowel sounds indicate a lack of gastrointestinal function, which supports the continuation of NPO status until bowel function returns. C. An increase in abdominal girth, even by 1 cm, can be concerning postoperatively and may indicate fluid retention or other issues, warranting further assessment. D. Pain at the operative site is expected post-surgery, but it does not directly relate to the child’s ability to resume oral intake.
