What is the appropriate action by a nurse if a client shows signs of dehydration?

Administering IV fluids as prescribed is the appropriate action when a client shows signs of dehydration. Dehydration indicates that the body is lacking sufficient fluids and electrolytes, and intravenous fluid administration is a direct and efficient way to restore hydration levels. IV fluids can provide a rapid infusion of fluids, which is critical in situations where oral intake may be inadequate or impossible, especially in cases of severe dehydration.

This intervention allows for precise control over the amount and type of fluid and electrolytes delivered to the patient, enabling a more immediate correction of fluid balance. Nurses play a crucial role in monitoring and adjusting the IV fluid therapy based on the client’s response and clinical status.

In contrast, restricting fluid intake would exacerbate the problem by further dehydrating the client. Increasing solid food intake may not adequately address the immediate need for fluid replenishment. Encouraging heavy exercise could be harmful for someone who is dehydrated, as physical activity increases fluid loss and may lead to further deterioration of the client's condition.
