Eductional Objective: Hypovolemia due to loss of sodium and/or water causes increased concentration of red blood cells (ie, hematocrit) and albumin as both of these blood components are trapped within the intravascular space. Hypovolemia also triggers increased absorption of uric acid in the proximal renal tubule, resulting in an increased serum uric acid level.
