Final answer:
The nurse should include interventions such as monitoring urine output, administering pain medication, and encouraging ambulation in the plan of care for a preschooler with Wilms' tumor.
Step-by-step explanation:
The nurse should include the following intervention in the plan of care for the preschooler with Wilms' tumor: Monitor and record the child's urine output regularly. This is important because Wilms' tumor can lead to kidney problems, and monitoring urine output can help assess kidney function. Additionally, this intervention can help identify any post-surgical complications or changes in the child's condition.
Administer pain medication as needed. Surgery can cause pain, and it is important to provide pain relief to ensure the child's comfort and well-being.
Encourage the child to ambulate independently post-surgery. Ambulation helps in preventing complications such as blood clots and improves overall recovery.
