A nurse administered ondansetron (Zofran) IV to a client 30 minutes ago. Which of the following findings should the nurse recognize as a complication of this medication?

A. Ondansetron (Zofran) can cause a prolonged QT interval, which may lead to arrhythmias. This is a known side effect and should be monitored. B. Spasms of the neck and face are more likely to occur with medications that have extrapyramidal side effects, such as certain antipsychotics, not ondansetron. C. Nausea and D. Vomiting are the symptoms ondansetron is intended to treat, so these are not complications.
