A nurse is caring for a client who is receiving ondansetron IV. Which of the following findings is an indication that the ondansetron is effective?

A. Absence of peripheral neuropathy is not an indicator of ondansetron’s effectiveness. Ondansetron is used to prevent nausea and vomiting, not to treat neuropathy. B. Increased urinary output is not related to the effectiveness of ondansetron. This medication does not affect urinary output. C. Reduced dizziness can be a beneficial effect but is not the primary indication of ondansetron’s effectiveness. Ondansetron is primarily used to prevent nausea and vomiting. D. Decreased nausea is the primary indication that ondansetron is effective. Ondansetron is an antiemetic used to prevent and treat nausea and vomiting, so a reduction in these symptoms indicates that the medication is working.
