Which condition describes not having enough fluid in the body?

• A. Hyperhydration
• B. Electrolyte imbalance
• C. Dehydration
• D. Anemia

Answer: (C)

Not having enough fluid in the body means dehydration. It happens when fluid losses exceed intake, so there isn’t enough water to support vital functions like maintaining blood volume, regulating body temperature, and enabling kidney function. In older adults, dehydration is a common risk because thirst may be less noticeable, and certain medications or illnesses can increase fluid loss. Recognizing signs such as dry mouth, reduced urination with dark urine, dry skin, dizziness, or confusion helps prevent serious issues like urinary tract infections, kidney problems, or hypovolemia. Hyperhydration describes having too much fluid in the body, which can cause swelling and electrolyte problems. Electrolyte imbalance refers to disturbances in minerals such as sodium or potassium, which can occur with dehydration but is a separate issue from the fluid deficit itself. Anemia is a condition with low red blood cell or hemoglobin levels, not a direct description of fluid status.
