Which action is most important for the nurse to implement to prevent nausea and vomiting in a patient who is prescribed intravenous (IV) chemotherapy?

b. Administer antiemetic drugs before administering chemotherapy.
c. Ensure that the chemotherapy is infused over a 4- to 6-hour period.
d. Assess the patient's responses every hour during the infusion period.
B
When emetogenic chemotherapy drugs are prescribed, the patient should receive antiemetic drugs as premedication before the chemotherapy drugs are administered. This allows time for prevention of chemotherapy-associated nausea and vomiting; however, the antiemetic therapy cannot stop until all risk for nausea and vomiting is passed. Patients become nauseated and vomit even when they are NPO.
