A nurse working in the intensive care unit (ICU) is caring for a client in progressive hemorrhagic shock. When planning care for this client, which does the nurse anticipate?
A) A sustained decrease of 10mmHg of the client's mean arterial pressure (MAP)
B) A blood loss of 25%
C) A change from aerobic to anaerobic metabolism
D) A decrease in hydrostatic pressure within the capillary, shifting fluid into the interstitial space
Answer: C
In intermediate or progressive hemorrhagic shock, there is a change from aerobic to anaerobic metabolism due to cellular hypoxia from decreased perfusion. This stage of shock occurs when there is sustained decrease of 20 mmHg or more of the client's MAP and a blood loss of 35% to 50%. The acid by-products of anaerobic metabolism causes an increase, not decrease, in hydrostatic pressure within the capillary, shifting fluid into the interstitial space.
