A client who was rescued from a house fire is admitted to the burn unit with deep dermal, partial thickness (second degree) burns over approximately one-third of the back and upper thighs. The nurse begins administration of prescribed crystalloid fluids for the first 24-hours following the burn incident. Which physiological response is promoted by the administration of the fluids?

RationaleA. In the early phase following a burn injury, there is increased capillary permeability due to the release of inflammatory mediators. This results in fluid shifting from the intravascular space into the interstitial space (capillary leaking), leading to hypovolemia and decreased tissue perfusion. Administering crystalloid fluids helps to restore intravascular volume (fluid resuscitation) and improve tissue perfusion.B. Burn injuries can lead to increased evaporative water loss through damaged skin (insensible water loss). Crystalloid fluids help to replace this lost fluid and maintain adequate hydration status in the client.C. In severe burn injuries, there may be a need for blood transfusions due to hemorrhage or ongoing blood loss. Crystalloid fluids can help to extend plasma volume temporarily until blood products are available for transfusion, thereby supporting circulatory stability.D. Burn injuries can disrupt electrolyte balance due to fluid shifts and tissue damage. Crystalloid fluids contain electrolytes (such as sodium and chloride) that help to restore and maintain electrolyte balance in the body.
