A 15-year-old with Hodgkin's Lymphoma is receiving Chemotherapy as an inpatient. She has vomited multiple times today despite receiving Zofran around the clock (ATC). The nurse will message the doctor and see if an order for dropdown can be placed to help with the nausea and vomiting. This patient has lost weight for the past three days. If this continues the nurse can anticipate needing to dropdown.

Rationale for correct choices: • Dexamethasone: This corticosteroid is often used as an adjunct antiemetic in chemotherapy-induced nausea and vomiting, particularly when standard agents like ondansetron are insufficient. It reduces inflammation and influences the chemoreceptor trigger zone to help control symptoms.\ • Begin parenteral nutrition: This supplies nutrients intravenously, bypassing the gastrointestinal tract, which is beneficial when severe vomiting prevents oral or enteral feeding. It ensures adequate caloric and nutrient intake during prolonged intolerance to GI feeding. Rationale for incorrect choices: • Phenergan: This antihistamine is effective for motion sickness or mild nausea but is less preferred for severe chemotherapy-induced symptoms in pediatric patients due to sedative and anticholinergic effects. It is not a first-line adjunct to ondansetron in oncology cases. • Protonix: This proton pump inhibitor reduces gastric acid secretion and is used for GERD or ulcer prevention, not for managing chemotherapy-related nausea and vomiting. Its mechanism does not address the cause of the patient’s symptoms. • Flagyl: This antimicrobial targets anaerobic bacterial infections and certain protozoa. It has no role in treating chemotherapy-induced nausea or vomiting and would not alleviate the patient’s acute symptoms. • Initiate enteral feeding: This provides nutrition via a feeding tube if oral intake is insufficient, but persistent severe vomiting makes tolerance poor. Enteral feeding is avoided until nausea is controlled. • Consult a dietitian: Involving a dietitian can help develop nutritional strategies, but it is an indirect intervention. If weight loss continues with ongoing vomiting, more immediate nutritional support is required. • Increase caloric intake: Advising increased calories is ineffective if the patient cannot tolerate food due to persistent nausea and vomiting, making parenteral or other specialized interventions more appropriate
