In this week of science we learned about sprains and strains. A foot sprain is ligament damage that is underneath the arches of the foot. Have the patient lay down and elevate the foot at or above the chest height. Apply an ice pack to the injured area to reduce swelling and pain. When using an ice pack you should place a cloth between the foot and the ice pack so there is no cold burn injury. In around 10-15 minutes take off the ice pack and wrap the foot in a pressure bandage. If the foot is discolored, numb, or not in alignment then it could be broken. For an ankle sprain there will be swelling and discoloration but no disformity. Apply an ice pack off and on for 15 minutes they are able to put some pressure on it. It is a sprain. If it is a break then it is unable to put any pressure on it at all. For a knee sprain apply an ice pack in intervals of 10-15 minutes to avoid ice burn. Wrap the knee e with a pressure bandage but avoid wrapping it too tight and cutting off circulation. For a sprained wrist apply an ice pack that is wrapped in a thin towel and place it on the wrist. Apply ice for ten to 15 minutes. Then wrap the area with a pressure or elastic bandage. Once the bandage is on you can reapply the ice for 10 to 15 minute intervals.
