A 50kg, 32-year-old man has sustained a stab wound to the right axilla with laceration of the axillary artery. The first response team notes a blood pressure of 80/20 mm Hg and rapidly infuses one liter of water instead of normal saline. The new condition of the body fluid compartments, as compared to the condition prior to infusion, is
a- expanded ECF volume and no change in body fluid osmolality
b- expanded ECF and ICF and decreased body fluid osmolality
c- expanded ECF and an increase in body fluid osmolality
d- expanded ICF and no change in body fluid osmolality
e- contracted ICF and expanded ECF with higher body
