Final answer:
The nurse should monitor a patient using Ondansetron (Zofran) for the adverse effects of prolonged QT interval, diarrhea, and headache. Shortened PR interval and Hyperglycemia are not typically associated with this drug.
Step-by-step explanation:
The nurse should monitor for several adverse effects of Ondansetron (Zofran), a medication commonly used to prevent nausea and vomiting caused by cancer chemotherapy, radiation therapy, or surgery. The options stated in the question include: a) prolonged QT interval, b) diarrhea, c) shortened PR interval, d) headache, and e) hyperglycemia. Ondansetron can indeed cause a prolonged QT interval, which refers to a condition of abnormal heart rhythm that can lead to serious health issues such as sudden cardiac death. The drug can also cause diarrhea and headache, which are common side effects. However, a shortened PR interval is not typically associated with ondansetron. Similarly, hyperglycemia, or high blood sugar, is not a known side effect of this medication. Thus, the nurse should closely monitor the patient, particularly for a prolonged QT interval, diarrhea, and headache.
