What is the primary reason for administering isotonic crystalloid IV fluids to a client with fluid volume deficit?

Rationale: A. Replacing lost blood components requires blood products, not isotonic crystalloids. B. Isotonic crystalloid fluids (e.g., 0.9% sodium chloride, lactated Ringer’s) are administered to restore extracellular fluid volume in clients with fluid volume deficit. C. While isotonic solutions contain electrolytes, their primary purpose is volume replacement, not rapid electrolyte correction. D. Correcting metabolic acidosis may require specific interventions; isotonic fluids alone do not address acid-base imbalances.
