Which electrolytes should be closely monitored during pediatric seizures and antiseizure therapy?

• A. Sodium, calcium, magnesium
• B. Potassium, phosphate, chloride
• C. Iron, copper, zinc
• D. Sodium, calcium, magnesium; and monitor liver and kidney function for certain antiseizure medications.

Answer: (D)

The main idea here is that seizure control and safety during antiseizure therapy hinge on keeping the brain’s electrical environment stable and watching for medication-related toxicity. Sodium, calcium, and magnesium directly influence neuronal excitability and seizure threshold. Disturbances in these electrolytes can provoke seizures or worsen their control, so they are routinely monitored in kids with seizures. At the same time, many antiseizure drugs are cleared by the liver and kidneys, and some can harm these organs or alter lab values. Checking liver and kidney function helps dose adjustments, detect toxicity early, and keep treatment safe. That combination—electrolyte surveillance plus organ-function monitoring for certain meds—best captures what needs to be watched.
