A nurse is reinforcing teaching with the parents of a child who has a new diagnosis of Wilms' tumor. Which of the following information should the nurse include in the teaching?

A. "You should give your child captopril 200 mg PO daily.": Captopril is an antihypertensive medication and is not routinely part of Wilms' tumor management unless the child has hypertension. This instruction is not standard teaching for preoperative care. B. "Your child will not require further treatment after removal of the tumor.": Wilms’ tumor management often involves multimodal therapy, including surgery, chemotherapy, and sometimes radiation. Telling parents that no further treatment is needed is inaccurate and could create false expectations. C. "Your child should have surgery in 7 to 10 days to remove the tumor.": The timing of surgery depends on the tumor stage, size, and the child’s condition. Preoperative planning varies and is individualized by the provider; providing a specific timeframe without provider instruction is inappropriate. D. "You should not palpate your child's abdomen prior to surgery.": Palpating the abdomen can risk rupturing the tumor and spreading malignant cells. Parents should be instructed to avoid abdominal palpation until the tumor is surgically removed to prevent complications.
