A.oliguria secondary to dehydration >>>>>>>>>WRONG B.an increased effective arterial blood volume >>>>>WRONG .IT DECREASED DUE TO DEHYDRATION C.a hyperchloremic normal anion gap metabolic acidosis before treatment >>>>>>>>>WRONG .CL LOST IN THE FORM OF HCL DUE TO VOMITING +LOSS NACL IN URINE D.an initial dilutional hyponatremia >>>>>THINK AND THINK AND THINK E.expansion of the intracellular fluid compartment >>>>>>>>>>>WRONG IT IS DECREASED THE ANSWER IS DDD Because the ECF [glucose] is markedly elevated, ECF osmolarity also is elevated (glucose is an osmotically active solute). As a result of this hyperosmolarity of ECF, water shifts out of the cells to achieve osmotic equilibration between ECF and ICF, diluting the solutes in the ECF and decreasing the blood Na

tinitial EBV explansion with dilutional hyponatremia is soon replaced by polyuria and dehydration with abrupt EBV extraction and severe dehydration, manifested by serum hyperK and hyperNa.
