What action can help relieve edema in nephrotic syndrome?

Elevating the legs and feet is an effective action to help relieve edema in nephrotic syndrome. This position encourages venous return from the lower extremities to the heart, which can help reduce fluid accumulation in the tissues. By elevating the legs, gravity assists in decreasing the hydrostatic pressure within the blood vessels, allowing excess fluid to move back into the circulation rather than staying trapped in the interstitial spaces, where it contributes to swelling.

The other options are less beneficial for addressing edema specifically. Keeping the legs free from movement may not promote circulation or lymphatic drainage, which are important in managing fluid buildup. Completely restricting fluid intake can lead to dehydration, which is not a recommended treatment for nephrotic syndrome and may have systemic effects. Applying ice packs could provide localized relief from discomfort but does not significantly address the underlying fluid retention associated with edema.
