Hypernatremia causes all Except 
Select and explain. 
A. Seizure, B. Thrombus, C. Brain haemorrhage, D. Central pontine myelinosis
B: Thrombus
Answer: B: Thrombus 
Explanation: Central pontine myelinolysis (CPM) is a neurological disorder that most frequently occurs after too rapid medical correction of sodium deficiency (hyponatremia). The rapid rise in sodium concentration is accompanied by the movement of small molecules and pulls water from brain cells. HYPERNATREMIA. Hypernatremia is defined as a serum sodium concentration in plasma >145 mEq/L. Whereas hyponatremia may cause seizures, hypernatremia is more likely to be a result of seizure activity (e.g., generalized tonic-clonic seizures). Intracellular glycogen is metabolized to lactate in muscle during seizures. Ref Davidson 23rd edition pg 367
