In brief: Yes and no

Yes, hypernatremia if severe enough, can be life threatening, although this is rare.
Hypernatremia itself is unlikely to cause delirium, (it can cause a coma, but not delirium), however the underlying cause of the hypernatremia can cause delirium.

In brief: Yes.

Both very high and very low sodium can cause delirium and death.
It takes a lot of things to go wrong to get your sodium that far out of line though. Usually there are many other tell tale signs and it is hard to say whether all the effect is due to sodium, the underlying cause of the disturbance, or to all the other things that get crazy when sodium is >150 or
