confused why this is not autonomic dysfunction or hyponatremia due to sweating and why is this orthostatic hypotension?

mdmofongo This one is tricky and come downs to choosing the “best” option. I can see why you were confused. However do note that in an autonomic dysfunction you will never present tachycardia as this patient does. I guess the key here is seeing how her BP normalizes once she is laying down? Sorry, this one is a kinda unusual presentation of Orthostatic hypo. +
