Not sure if this is correct thinking but how I got this right was:
1. She is hypovolemic
2. Likely retaining salt so water follows (ADH or just renal dynamics in general). This is how I ruled our hypokalemia and hyponatremia
3. If she is hyponatremic b/c sweating then why wouldn't she also be hypokalemic? so both have to wrong because both can't be right
4. Volume depletion ==> orthostatic hypotension
I thought that orthostatic hypotension was more of a chronic condition, but I fooled myself into believing that.
