She's vomiting - Metabolic Alkalosis > loss of HCL > ie; acid, there would be increased HCO3
Anion gaps are usually with metabolic acidosis because in alkalosis there is high HCO3 which keeps gap normal.
For the K+ > vomiting > loose water along with the vomit > decreased blood volume > RAAS activation > aldosterone secretes H+ and K+ > hypokalemia

cause of metabolic alkalosis vomiting
in someone whos a bulemic, hypokalemia and hypochloremia are common.
anion gap formula Na-(Cl+bicarb)
Since we have excessive bicarb there shouldn't be a large gap. Normal is 8-12.
