The MOST common precipitant of status epilepticus in children is

Correct Answer: B

Rationale: Fever is the most common trigger of status epilepticus in children, often via febrile seizurprogressing to prolonged events, per studi(e.g., Chin et al.). CNS infection , medication change , trauma , and metabolic causare less frequent precipitants. Fevers prevalence in young children drivits dominance, making B the correct answer.

Correct Answer: A

Rationale: Personality change with seizursuggests an intracranial tumor , as mass effects or frontal/temporal lobe irritation can alter behavior and trigger epilepsy. Degenerative and metabolic diseascause diffuse symptoms, not focal personality shifts. Stimulants and congenital issulack this link. Tumors focal impact makes A the correct answer.

Correct Answer: C

Rationale: AED discontinuation is recommended after 2 years seizure-free, per AAN guidelines, balancing relapse risk (~30%) with drug burden. Shorter periods (A-B) increase recurrence; longer may be unnecessary. Two years stability, supported by trials, makes C the correct answer.

Correct Answer: D

Rationale: Aicardi syndrome, an X-linked disorder, featurcoloboma , retinal lacunae , corpus callosum agenesis , and severe seizur. Aminoaciduria is not associated; metabolic errors are absent. This neurologic-ocular focus makes D the exception and correct answer.

Correct Answer: D

Rationale: In status epilepticus, glucose , magnesium , and CBC are routine to identify reversible caus(e.g., hypoglycemia). CT assessstructural issues. MRI is not urgent; its detailed but delayed, unlike immediate labs or CT. This urgency distinction makes D the exception and correct answer.
