If a client is displaying signs of dehydration, which assessment finding is expected?

When a client is displaying signs of dehydration, an increased respiratory rate is expected due to the body's attempt to maintain oxygen levels and compensate for the decreased fluid volume. As dehydration progresses, the body may begin to show signs of distress, including a higher respiratory rate, as it tries to enhance oxygen delivery to tissues that might be compromised due to inadequate blood volume.

In contrast, improved peripheral edema would typically not be observed during dehydration, as edema is related to fluid retention rather than fluid loss. Elevated blood pressure is usually not expected since dehydration often leads to reduced blood volume, which can result in lower blood pressure. Stable electrolyte levels would not be commonly seen either, as dehydration affects the concentration of electrolytes in the body, often leading to imbalances. Therefore, the increased respiratory rate is a clear and relevant physiological response to dehydration.
