Following a sprained ankle, which discharge instruction is essential?

• A. Maintain cold application on and off every 20 minutes
• B. Apply ice to affected ankle for 2 to 3 days
• C. Wrap cold application in a towel before using
• D. Elevate the leg and keep it elevated

Answer: (B)

After a sprain, controlling swelling and pain early is crucial, and cold therapy is a key part of that plan. Applying ice to the injured ankle for about 15–20 minutes at a time, several times a day, for the first 2–3 days helps by causing vasoconstriction and reducing capillary leakage. This limits edema and eases pain, supporting faster return to activity. Always use a barrier, such as a towel or cloth, between the ice and skin to prevent frostbite, and discontinue if numbness, color change, or burning occurs. Elevation complements icing by helping reduce swelling, but the essential discharge instruction highlighted here is initiating ice therapy for the initial days to manage swelling and pain.
