What does the 'I' in RICE stand for when treating a sprain?

The "I" in RICE stands for Ice. In the context of treating a sprain, applying ice is a crucial step in managing the injury. Ice helps to reduce swelling and numb the area, which can alleviate pain and prevent further damage. The mechanism behind using ice involves vasoconstriction, which decreases blood flow to the area, ultimately leading to reduced inflammation and pain.

While other options represent concepts relevant to injury management, they do not directly correspond to the "I" in RICE. For instance, inflammation is a result of the injury rather than a method of treatment, immobilization is a separate component that encourages rest and stability, and injury is a broader term encompassing the overall damage that has occurred. Focusing on the application of ice is fundamental to initiating the healing process for sprains effectively.
