What is the primary purpose of elastic stockings as prescribed for a resident with a fractured right hip?

Elastic stockings are primarily designed to promote venous return and prevent the formation of thrombi, particularly in individuals who are immobile or have limited mobility, such as a resident with a fractured hip. When a person is unable to move around freely due to an injury, blood circulation in the lower extremities can become compromised. This stagnant blood flow increases the risk of deep vein thrombosis (DVT), where blood clots form in the deep veins of the legs.

The compression provided by elastic stockings helps to support the veins, facilitating blood flow back to the heart and reducing the likelihood of clot formation in the legs. This proactive measure is crucial for residents with mobility issues, particularly after a hip fracture, as they may be confined to bed rest or limited in their movement for an extended period.

While elastic stockings may also provide some warmth and contribute indirectly to skin health by improving circulation, their main therapeutic purpose in this context is specifically to prevent thrombi from forming, making this answer the most appropriate choice.
