Status epilepticus is a neurologic emergency and is defined as ongoing seizure activity or repetitive seizurwithout return of consciousness for greater than
Correct Answer: B
Rationale: Status epilepticus is defined as >30 minutof seizuror no recovery between, per ILAE, risking neuronal damage. Shorter is prolonged; longer (C-E) exceeds standard. Thirty minutguidintervention, making B the correct answer.
Question 2 of 5
An adolescent patient develops both proximal and distal weakness of the extremitiin an episodic, relapsing-remitting pattern; he also experiencnumbness and tingling. Of the following, the MOST likely diagnosis is
Correct Answer: D
Rationale: CIDP fits relapsing-remitting proximal/distal weakness with numbness, per neurology, from immune-mediated demyelination. CMT is progressive; myasthenia fatigable; hypothyroidism systemic; Guillain-Barré acute. CIDPs pattern makes D the correct answer.
Question 3 of 5
The triad of complete agenesis of the cerebellar vermis, cystic dilation of the fourth ventricle, and enlarged posterior fossa is seen in
Correct Answer: B
Rationale: Dandy-Walker malformation featurvermis agenesis, fourth ventricle cyst, and enlarged posterior fossa, per radiology texts. Corpus callosum agenesis affects midline; holoprosencephaly forebrain; hydranencephaly cortex loss. Triad specificity make B the correct answer.
Question 4 of 5
Ataxia is the inability to make accurate, smooth and coordinated movements, usually due to a dysfunction of the cerebellar pathways. Of the following, the MOST common cause of acute ataxia in childhood is
Correct Answer: D
Rationale: Postinfectious acute cerebellar ataxia is the most common cause of acute childhood ataxia, per pediatrics, often post-viral (e.g., varicella). Strokand MS are rare; postictal transient; tumors chronic. Postinfectious frequency makes D the correct answer.
Question 5 of 5
A state of responsiveness to pain but not to other stimuli is
Correct Answer: C
Rationale: Stupor is responsiveness to pain only, per neurology, with reduced arousal beyond lethargy or obtundation . Coma lacks response; consciousness full. Stupors definition makes C the correct answer.
