Final answer:
Dizziness is a recognized adverse effect of ondansetron IV and is the correct answer the nurse should recognize among the given options.
Step-by-step explanation:
The nurse is assessing a client who was administered ondansetron IV 1 hr ago. Ondansetron is a medication commonly used to prevent nausea and vomiting associated with cancer chemotherapy, radiation therapy, or surgery. Among the listed options, the adverse effect that the nurse should recognize as being associated with ondansetron is option (a) dizziness. Ondansetron can indeed cause dizziness which can be a common side effect, especially after intravenous administration due to its rapid absorption. It is important for the nurse to monitor for other adverse effects such as changes in blood pressure and heart rate, as well as symptoms of potential dehydration due to vomiting if applicable. Options (b) bradycardia, (c) tardive dyskinesia, and (d) dyspepsia are not typically associated with ondansetron.
