After a client is diagnosed with a sprained ankle, which self-care measure shows an understanding of next steps?

Elevating the foot above the level of the heart is an important self-care measure following an ankle sprain because it helps reduce swelling and promotes proper blood circulation. Elevation assists in minimizing the accumulation of fluids in the affected area and can alleviate pain. When combined with other initial treatment approaches, such as rest and ice application, elevation plays a crucial role in the overall management of a sprained ankle.

In the context of the other options, applying heat is not appropriate for a fresh injury as it can increase inflammation and swelling. Walking on the sprained ankle is generally discouraged during the initial healing phase because it can exacerbate the injury and delay recovery. While avoiding weight-bearing activities can sometimes be necessary, doing so without proper context may not provide the balanced rest and rehabilitation needed to effectively manage the sprain.
