Which method can help with the swelling of an injured limb according to the RICE method?

Applying heat
Raising the limb
Massaging the area
Drinking fluids

The correct answer is: Raising the limb

The RICE method is a well-established first aid technique used to treat soft tissue injuries, such as sprains and strains. It stands for Rest, Ice, Compression, and Elevation. Raising the limb, as suggested in the correct answer, plays a critical role in managing swelling. By elevating the injured area above the level of the heart, you help reduce blood flow to the site of injury, which in turn decreases swelling and promotes better circulation, ultimately aiding recovery. The other methods mentioned in the choices do not align with RICE principles. Applying heat can increase blood flow and potentially worsen swelling. Massaging the area could aggravate the injury and increase pain. Drinking fluids, while important for overall health, does not specifically target swelling in an injured limb. Therefore, raising the limb is the most effective method in this context.
