Final answer:
During nausea related to medication therapy, a nurse should offer a child with leukemia bland and dry foods as they are gentle on the stomach and are more likely to be tolerated. These include toast, crackers, and plain rice. Hydration with water or clear broths is also critical.
Step-by-step explanation:
When a child with leukemia is experiencing nausea related to medication therapy, the nurse concerned about the child's nutritional status should offer bland and dry foods. Fatty and spicy foods might aggravate the nausea, and while carbonated beverages may sometimes help, they are not as mild and typically not as effective as bland and dry foods in managing nausea.
Example of bland and dry foods include items like toast, crackers, plain rice, and cereal, which are gentle on the stomach and more likely to be tolerated during episodes of nausea. Maintaining hydration is also important, and water or clear broths can be soothing. It's essential to provide nutrition that the child can keep down, ensuring a better chance for the necessary nourishment during treatment.
