With her admisssion hypokalemia I would like to know what her serum glucose level was prior to administration of 5% dextrose. Insulin is often used to drive down potassium in clinical settings.

Me too, and what do you wanna bet they put a line in right at the scene? So the glucose level would have stabilized by the time she made it to the ED.

It's either insulin injection or some fairly rare undxed condition, probably endocrine.

That is what makes sense. Young, healthy female walking around with a semum K of 2.0...no diuretics, no evidence of buhlemia (only conjecture)....not likely with other electrolyte parameters normal. But a large injection of insulin......waiting......followed by an administration of glucose would make sense...just no evidence for it.
