What clinical sign might suggest dehydration in a patient?

• A. Increased peripheral circulation
• B. Stable blood pressure
• C. Orthostatic hypotension
• D. Elevated oxygen saturation

Answer: (C)

Orthostatic hypotension is a clinical sign that can suggest dehydration, as it occurs when a person's blood pressure drops significantly when they stand up from a sitting or lying position. This drop in blood pressure can be attributed to a decrease in blood volume that often accompanies dehydration. When the body doesn’t have enough fluids, it struggles to maintain adequate blood circulation, particularly when the position changes, leading to symptoms such as dizziness or lightheadedness. In cases of dehydration, the body is unable to compensate for the loss of fluid. Therefore, when a patient experiences orthostatic hypotension, it can indicate that they are not maintaining adequate blood volume and are potentially dehydrated. Recognizing this sign is crucial for nursing care, as it can guide further assessment and timely interventions, such as administering fluids.
