Pediatric Neurology Question Bank Questions
Question 1 of 5
Higher risk of recurrence of the febrile seizure is associated with lower serum
Correct Answer: A
Rationale: Lower serum sodium increasfebrile seizure recurrence risk by lowering seizure threshold via hyponatremias effect on neuronal excitability. Potassium , chloride , calcium , and magnesium imbalancare less linked. Studi(e.g., Pediatrics) highlight sodiums role, making A the correct answer.
Question 2 of 5
Subtle seizurinclude all the following EXCEPT
Correct Answer: D
Rationale: Subtle seizurin neonatinclude blinking , mouthing , heart rate chang, and apnea , reflecting autonomic or minor motor signs. Hypotension episodare not a seizure feature; theyre systemic, not neurologic. This distinction seizure versus effect makes D the exception and correct answer.
Question 3 of 5
Status epilepticus is a medical emergency that should be anticipated in any patient who presents with an acute seizure. It is defined as continuous seizure activity or recurrent seizure activity without regaining of consciousness lasting for more than
Correct Answer: C
Rationale: Status epilepticus is defined as seizurlasting >30 minutor recurrent without recovery, per ILAE, requiring urgent treatment due to neuronal injury risk. Shorter durations (A-B) are prolonged seizures; longer exceed standard. Thirty minutclinical threshold makes C the correct answer.
Question 4 of 5
The aura associated with migraine is a neurologic warning that a migraine is going to occur. Of the following, the LEAST common type of typical auras is
Correct Answer: D
Rationale: Migraine auras include visual (C, most common, ~90%), sensory , and dysphasic types. Vertigo and distortion are rarer, with vertigo least frequent (~10%) per studies, often tied to vestibular migraine. Visual dominance makes D the correct answer.
Question 5 of 5
A slowly progressive ataxia that involvthe lower extremitito a greater degree than the upper extremities. The Romberg test result is positive; the deep-tendon reflexare absent (particularly at the ankle), and the plantar response is typically extensor (Babinski sign). Of the following, the MOST likely cause of this ataxia is
Correct Answer: B
Rationale: Friedreich ataxia matchthis profile: progressive lower limb ataxia, absent reflexes, positive Romberg (sensory loss), and Babinski sign, from GAA repeat expansion. Ataxia-telangiectasia adds telangiectasia; abetalipoproteinemia lipid issues; Roussy-Levy tremor; Ramsay Hunt is unrelated. Friedreichs genetics make B the correct answer.
