Select and explain. 
A. Glucose, B. Dexamethasone, C. Calcium gluconate, D. Normal saline
B: Dexamethasone
Answer: B: Dexamethasone 
Explanation: Coicosteroids should not be used, and although many paediatricians use mannitol, there is no evidence for its effectiveness. Babies with severe asphyxia may appear to settle relatively quickly after the resuscitation, but there is likely to be a deterioration after 6-12 hours or so as cerebral oedema develops.
