resp 50 per min,high pitch cry,irritable,low bp,sz all pointing towards septicemia/meningitis and the Q is about wat exactly caused the pt sz...hmmmmm
i`ll go with Meningitis...
if thew options had hypernatrimia i`d have certainly opted for it....
hypocal will cause tetany which is diff fron sz .. option a
ther is no hypoglycemia... ....b
hypomanesemia will cause arrythmias.....c (it might have been accompanied with hypokalemia which is not give here, and accompanied decrease or absent bowel sounds)
intracranial h`rrage is not the possibility here...d
any other explanation is welcome, thx

It's meningitis... he is septic hence the low BP... his hypernatremia could be due to severe dehydration and Na retention to increase the BP...
