Step-by-step explanation:
The correct first aid for a sprained ankle is to wrap the ankle in an elastic bandage.
This helps to support the injured ankle and reduces swelling. It is important to keep the ankle elevated, so keeping the ankle below the heart level is not the correct action.
Applying heat immediately may actually increase swelling, so it is not recommended. Walking on the ankle quickly to restore motion can worsen the injury, so it should be avoided.
