Which combination best reflects the limitations of prehospital fluid resuscitation in hemorrhagic shock?

In hemorrhagic shock, fluids used before reaching the hospital have several limitations that together explain why the most complete answer is all of the above. First, these fluids do not carry oxygen themselves; oxygen delivery depends on red blood cells and perfusion, so simply expanding volume doesn’t fix the underlying oxygen delivery problem. Second, introducing large volumes of crystalloids can dilute the blood’s clotting factors and platelets, worsening coagulopathy and potentially increasing ongoing bleeding. Third, raising intravascular pressure with fluids can raise hydrostatic pressure at injury sites, dislodging forming clots and promoting further hemorrhage. At the same time, substantial fluid administration can contribute to pulmonary edema, impairing gas exchange. Taken together, these factors illustrate why all of the above appropriately reflect the limitations of prehospital fluid resuscitation in hemorrhagic shock.
