In case of a sprained ankle, placing an ice bag on the sprained part is the correct course of action. Ice helps to reduce swelling and inflammation by constricting blood vessels and numbing the area. This can provide immediate relief and prevent further damage. Rubbing the sprained part to keep it warm or applying hot water can worsen the swelling and increase pain. It is not advisable to let the friend walk to the school clinic as walking on a sprained ankle can cause further injury.
