Explanation:

B

Explanation:

The most beneficial regimen to minimize nausea and vomiting associated with chemotherapy is to administer a 5-hydroxytryptamine-3 receptor antagonist (e.g., ondansetron) before the chemotherapy is begun. The goal is to prevent anticipatory signs and symptoms. The child will experience nausea with chemotherapy whether or not food is present in the stomach. Because some children develop aversions to foods eaten during chemotherapy, refraining from offering favorite foods is advised. Keeping the child NPO until nausea and vomiting subside will help with this episode, but the child will have discomfort and be at risk for dehydration.
