Which term refers to swelling of the limbs due to fluid buildup?

• A. Bradycardia
• B. Tachypnea
• C. Peripheral edema
• D. Hematuria

Answer: (C)

Peripheral edema is swelling of the limbs due to fluid buildup. Edema means too much fluid collecting in the tissue spaces, and when it occurs in the arms or legs it’s called peripheral edema. This term helps clinicians describe swelling that isn’t just a surface change but a fluid-related issue affecting the extremities, often related to fluid balance or circulatory problems. Knowing this term helps you recognize why the limbs look puffier and feel heavier.

For contrast, bradycardia means a slow heart rate, tachypnea is rapid breathing, and hematuria is blood in the urine. These describe other signs or conditions and aren’t the terms used for limb swelling from fluid buildup.
