As far as I remember correction of Hyponatraemia must be slow instead of fast in order to avoid central pontine lesion.
So C is the answer>

Additionaly I would go for NSAID as well as a wrong answer because I could not think any cause to be treated with it. Tetracyclin could be useful since pnumonia can be a cause and AB is a Tx for that.

Incorrect choices are:
b It's not caused by adenomas. It's caused be ectopics, intracranial masses and trauma.
c Hyponatemia should be corrected slowly
e NSAID makes SIADH worse by potentiating ADH effects.
Correct choices are:
a
d Tx is demeclocycline which blocks ADH effects.

Bellkicker,
why is a also a correct answer? I mean why isnt ADH measurable in SIADH, it is increased right? so we have measured it as increased....?

Meg,
ADH is normally unmeasurable. I don't know what kind of level it reaches in SIADH; all I know is that it becomes measurable.
