MCQ - Neurology & Neuroprotection

Welcome to your Neurology and Neuroprotection

Which of the following documented episodes of neonatal hypoglycaemia specifically meets the criteria for referral for a brain magnetic resonance imaging (MRI) scan?

A single blood glucose reading of 1.5 mmol/L (27 mg) on day 1 in an infant with no abnormal signs.

Two consecutive blood glucose readings of 1.8 mmol/L (36 mg) in an infant who is feeding effectively.

A single blood glucose reading of 2.2 mmol/L (45 mg) in a neonate presenting with lethargy and reduced consciousness.

A transient blood glucose of 2.0 mmol/L (36 mg) in an asymptomatic infant of a diabetic mother.

A transient blood glucose of 0.8 mmol/L ( 14 mg) in an infant where the presence of acute neurological dysfunction is completely excluded.

None
