A 3-year-old child is admitted with a Stage II Wilm's tumor. Which preoperative intervention(s) should the nurse implement? Choose all that apply.

A. Explain expected side effects of postoperative chemotherapy: Chemotherapy and its side effects are typically discussed after surgery when the treatment plan is clearer. The focus before surgery should be on preparing the child and family for the surgery itself. B. Monitor blood pressure every 2 hours for hypertension: Wilm's tumor can be associated with hypertension due to renin production from the tumor, so monitoring the child's blood pressure closely is essential to detect any signs of hypertension early. C. Provide parents with simple explanations and repeat often: Simplified, repeated explanations are key to helping parents understand the diagnosis and surgical procedure. This approach supports emotional comfort and ensures informed decision-making. D. Attend all healthcare provider and parent conferences: While it is important to support the family, the nurse’s role in attending all healthcare provider and parent conferences is not mandatory unless specifically needed for continuity of care. E. Measure the child's abdominal girth: Measuring abdominal girth is essential preoperatively to monitor for any abdominal changes, such as swelling or distension, which could indicate tumor growth or other complications related to the Wilm's tumor.
