Which condition occurs when there is not enough fluid in the body?

• A. Hyperhydration
• B. Dehydration risk
• C. Dehydration
• D. Hyponatremia

Answer: (C)

Not enough fluid in the body is dehydration. Dehydration means the body’s water content is too low to support normal functions. It can happen from not drinking enough, sweating, fever, vomiting, or diarrhea, and it’s especially important to watch for in older adults who may have a reduced sense of thirst or take medicines that conserve or lose fluids. Signs include dry mouth, dark urine with reduced urine output, dizziness, confusion, and fatigue. If it worsens, dehydration can lead to electrolyte imbalances and kidney problems, so it’s vital to report and address it promptly. The other terms describe different situations: having too much fluid is hyperhydration; dehydration risk refers to a likelihood of becoming dehydrated rather than an actual current state; and hyponatremia is a low blood sodium level, which is an electrolyte issue that can occur with wrong fluid balance but is not the definition of not having enough body fluid.
