Practice Question

Answer Choices:
Correct Answer:
Prolonged QT interval
Rationale:
💠 Mechanism: Ondansetron is a serotonin (5-HT₃) receptor antagonist used to prevent nausea and vomiting.
💠 Cardiac Risk: It can prolong the QT interval, increasing the risk for torsades de pointes and life-threatening arrhythmias.
💠 Contraindication: Avoid use in clients with existing QT prolongation or electrolyte imbalances (e.g., hypokalemia, hypomagnesemia).
💠 Monitoring: ECG monitoring is recommended in cardiac, elderly, or high-risk patients.
💠 Other Effects: Common mild effects include headache and constipation, not cardiac rhythm changes.
