All are features of hypernatremia except

Ans. is 'c' i.e., Periodic paralysis Periodic paralysis, is seen in hyponatermia Clinical features of Hypernatremia :? Most patients with hypernatremia are dehydrated and have the typical signs and symptoms of dehydration. Hypernatremia even without dehydration causes central nervous system symptoms that tend to parallel the degree of sodium elevation and the acuity of the increase. Patients are irritable, restless weak and lethargic Some have high pitched cry and hyperpnea. Ale patient are very thirsty. Hypernatremia causes fever although many patients have underlying process that contributes to the fever Except for dehydration, there is no clear direct effect of hypernatremia on other organs or tissues except the brain. Complication of hypernatremia :? Brain hemorrhage is the most devastating consequence of hypernatremia. As the extracellular osmolarity increases water moves out of brain cells, resulting in decrease in brain volume. This can result in tearing of intra cerebral veins and bridging vessels as the brain moves away from the skull and the meninges. Patient may have subarachnoid, subdural and parenchymal hemorrhage. Seizure and coma are possible sequale of the hemorrhage even though seizures are more common during t/t. Thrombotic complications are common in severe hypernatremic dehydration and include stroke, dural sinus thrombosis, peripheral thrombosis and renal vein thrombosis. The intracranial tension can be increased due to hemorrhage
