Final answer:
The nurse should promote adherence to dietary restrictions with a matter-of-fact demeanor, reinforcing the importance and ensuring the parents understand the postoperative care plan.
Step-by-step explanation:
The best way for the nurse to promote adherence to the restrictions for a toddler on the pediatric unit after colorectal surgery is by handling dietary changes in a matter-of-fact way. By conveying the dietary restrictions with a straightforward, professional demeanor, the nurse establishes the importance of these changes as part of the recovery process. Furthermore, consistent reinforcement by the healthcare team—comprising the surgeon, nurse, and dietitian—about the importance of adhering to the postoperative dietary regimen can significantly impact the parents' approach to the child's food intake. It is essential to provide education and guidance that is understandable and manageable for the parents, who play a critical role in ensuring that their child follows the postoperative care plan.
