Step-by-step explanation:
The treatment plan for ondansetron (also known by the brand name Zofran) under a Nausea/Vomiting Medical Directive involves its administration to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, or surgery. Ondansetron works by blocking the actions of chemicals in the body that can trigger nausea and vomiting. It is commonly provided in the form of tablets or intravenously, as depicted by a 4 mg vial of ondansetron for intravenous injection in the provided image.
For individuals undergoing treatment such as radiation therapy, prescription medications like ondansetron are an important part of the management plan to alleviate symptoms of nausea. This medication must be used as directed by a healthcare professional, and it is classified as a controlled substance due to its chemical properties and potential for misuse.
