Which of the following should be monitored with clients prescribed antiepileptic drugs (AEDs)?

• A. Toxicity
• B. Adherence to drug therapy
• C. Plasma concentration and effectiveness
• D. All of the above

Answer: (D)

Monitoring antiepileptic therapy involves watching three areas: safety, adherence, and drug levels to ensure seizures are controlled without harming the patient. Many AEDs have narrow therapeutic ranges and potential toxicities, so assessing for adverse effects and performing appropriate labs helps prevent harm. Adherence matters because missing doses often leads to breakthrough seizures; using patient education, reminders, and refill checks supports consistent dosing. Checking plasma concentrations alongside clinical effectiveness guides dose adjustments and helps detect nonadherence or drug interactions. Because all three aspects contribute to safe, effective seizure control, monitoring across toxicity, adherence, and plasma levels is the comprehensive approach.
