What is the key nurse intervention in the initial management of a sprained ankle?

The application of ice is a critical intervention in the initial management of a sprained ankle because it helps to reduce inflammation and manage pain. Ice therapy works by causing vasoconstriction of the blood vessels, which decreases blood flow to the injured area, thereby minimizing swelling and inflammation. Additionally, the cold temperature provides immediate pain relief, which is essential in the acute phase of a sprain.

Applying ice should typically be done for 15 to 20 minutes at a time, and it's often recommended to repeat this process multiple times a day during the first 48 to 72 hours after the injury. This proactive approach aids in promoting recovery and helps prevent further complications or prolonged pain.

Constant immobilization, while it may seem beneficial, can lead to stiffness and delayed recovery if overdone. The act of immobilizing the ankle is important, but it should be balanced with the need to gently move the joint to maintain flexibility.

Performing heel stretches or any form of exercise is typically not appropriate immediately after a sprain, as it can exacerbate the injury. Similarly, elevating the leg is beneficial, but it should not be limited to just when swelling occurs; consistent elevation helps in promoting venous return and reducing edema right after the injury happens.
