Why do you think the BUN and creatinine are elevated?
Also what do the low Hgb and Hct levels indicate about the rapidity of C.W.'s blood loss?
Inadequate renal perfusion as a result of hypovolemia. An elevated BUN may also be secondary to
hemolysis related to digestion of blood in the GI tract.
Because the Hgb and Hct are low, the bleeding has probably taken place over several days.
Interstitial fluid has had time to move into the vascular compartment, diluting the red blood cells
(RBCs). In an acute bleed, the Hgb and Hct would be normal (undiluted).
