Final answer:
Lactated Ringer's is the appropriate fluid for prehospital management of hypovolemic shock due to its isotonic nature and electrolyte composition.
Step-by-step explanation:
The appropriate fluid for the prehospital management of hypovolemic shock is Lactated Ringer's. This solution is isotonic with respect to body fluids, which is essential to ensure that there is no net flow of water into or out of the body's cells, preventing cell damage. Lactated Ringer's contains electrolytes that are similar in concentration to those found in the body's own fluids, including sodium, potassium, calcium, chloride, and lactate, providing a balanced electrolyte replenishment.
