Which physical assessment technique will the nurse omit when caring for a 2-year-old child diagnosed with Wilms' tumor?

A. Percussing ankle and knee reflexes. Safe and non-invasive, and does not risk disturbing the tumor. B. Assessing for bowel sounds. Routine part of assessment and does not involve manipulating the tumor. C. Performing range-of-motion exercises on lower extremities. Safe and non-invasive, unrelated to the abdominal tumor. D. Palpating the abdomen. Palpating the abdomen in a child with Wilms' tumor is avoided to prevent the risk of tumor rupture and subsequent metastasis.
