Which of the following is a sign of fluid overload?

• A. Dizziness
• B. Edema
• C. Increased appetite
• D. Fatigue

Answer: (B)

Edema is a significant sign of fluid overload because it indicates the accumulation of excess fluid in the body's tissues. When the body retains more fluid than it can effectively manage, it can lead to swelling, particularly in areas such as the legs, ankles, or around the eyes. This condition arises from increased blood volume and can result from various causes, including heart failure, kidney problems, or excessive fluid intake.

In contrast, dizziness, increased appetite, and fatigue can relate to numerous other health conditions and are not specific indicators of fluid overload. Dizziness could be a result of low blood pressure or dehydration, increased appetite may not necessarily indicate a fluid balance issue, and fatigue is a common symptom that can arise from various chronic conditions or lifestyle factors. Therefore, while these symptoms are important to monitor, they do not specifically signal fluid overload as clearly as edema does.
