Which symptom suggests fluid volume deficit?
Asked on Dec 23, 2025
Answer
Fluid volume deficit, commonly known as dehydration, can present with several clinical symptoms. One key symptom that suggests fluid volume deficit is orthostatic hypotension, which is a drop in blood pressure upon standing that can lead to dizziness or lightheadedness.
Example Concept: Orthostatic hypotension occurs when there is insufficient fluid in the vascular system, causing a decrease in blood pressure when changing positions from lying or sitting to standing. This symptom is a result of the body's inability to maintain adequate blood flow and pressure due to reduced fluid volume, and it is a critical indicator of dehydration in patients.
Additional Comment:
- Monitor vital signs, especially blood pressure and heart rate, for changes indicating fluid volume deficit.
- Assess for other signs of dehydration, such as dry mucous membranes, decreased skin turgor, and concentrated urine.
- Consider the patient's intake and output balance, and review recent history for potential causes of fluid loss.
- Remember the importance of rehydration and electrolyte balance in managing fluid volume deficit.
- Use ABCs (Airway, Breathing, Circulation) to prioritize care, ensuring patient safety and stability.
