<prompt> All of the following are seen in persisting vomitting EXCEPTHypokalemiaDecreased K in urineElevated pH of bloodMetabolic alkalosis  <response>: Presistant vomitting causes loss of hydrochloric acid, K Na ions and body fluids. Loss of HCl leads to metabolic alkalosis. Loss of K leads to hypokalemia which fuher increases the pH of blood intracellular K ions come out in the ECF by exchanging with H ions of ECF. Hypokalemia should lead to decreased K in urine but this does not happen - Low Na and hypovolemia would lead to increased aldosterone secretion which would increase the reabsorption of Na ions in the distal renal tubular in exchange of K ions. Thus K ions excretion in urine is increased despite hypokalemia.
