What is the purpose of a pressure bandage?

• A. To control bleeding
• B. To reduce swelling by cooling
• C. To immobilize a limb
• D. To apply lotion

Answer: (B)

Pressure bandages are used to control bleeding by applying firm, even pressure to a wound. That sustained pressure helps compress blood vessels, slowing or stopping blood flow and reducing blood loss. While a snug wrap can help limit swelling to some extent by restricting fluid leakage, cooling the area is done with a cold pack, not the bandage. It isn’t intended to immobilize a limb or to apply lotion. After applying, monitor circulation beyond the bandage and loosen if there are signs of numbness, color changes, or tingling.
