What is the rationale for including a toxicology screen in seizure evaluation?

• A. To evaluate kidney function.
• B. To assess lipid profile.
• C. To determine blood type.
• D. To assess exposure to drugs or toxins that could provoke seizures.

Answer: (D)

Seizures can be triggered by toxins or substances in the body, so a toxicology screen is included to identify any drugs or toxic exposures that could provoke seizures. Discovering a toxin or a drug in the system helps explain why the seizure occurred and guides immediate management—some substances require specific antidotes, dose adjustments, or different withdrawal treatments, and knowing what’s present helps prevent re-exposure and informs safety measures.

Other tests like evaluating kidney function, lipid profile, or blood type don’t directly identify a toxin or trigger for seizures; they may be useful for overall medical status or logistical reasons, but they don’t explain the seizure’s cause.
