Which measure directly helps to limit swelling by applying pressure?

• A. Elevation
• B. Rest
• C. Ice
• D. Compression

Answer: (D)

Compression directly applies external pressure to the injured area, which helps limit swelling by constraining fluid buildup in the tissues and aiding venous and lymphatic return. The added pressure reduces capillary leakage and helps push excess fluid back toward circulation, stabilizing the area and keeping swelling under control. Elevation and rest work by different means—elevation uses gravity to encourage fluid away from the injury, rest reduces stress on the area, and ice causes vasoconstriction to limit inflammation—so they don’t apply the direct external pressure that compressive wrapping provides. If using compression, ensure the bandage is snug but not too tight, and check for numbness or color changes, removing it if those occur.
