Question 24

Elastic stockings are used to decrease edema.

Elastic stockings are primarily designed to reduce swelling, or edema, in the legs by applying graduated compression. This compression helps improve blood circulation and prevents fluid accumulation in the tissues.

A) decrease blood pressure

While elastic stockings may have some effect on venous return and overall circulation, they are not specifically intended to decrease systemic blood pressure. Their primary function is focused on promoting venous blood flow and reducing edema rather than affecting arterial blood pressure levels.

B) heal open areas

Elastic stockings are not designed to heal open wounds or areas of skin breakdown. Instead, their role is to provide support and compression to the legs, which aids in circulation but does not directly promote the healing of skin lesions or open areas.

C) decrease edema

This option accurately reflects the primary purpose of elastic stockings, which is to decrease edema. By providing graduated compression, these stockings help to prevent fluid from pooling in the legs, thereby reducing swelling and discomfort.

D) prevent pressure sores

Although elastic stockings can provide support and may indirectly reduce the risk of pressure sores by improving circulation, they are not specifically designed for this purpose. Pressure sore prevention typically involves repositioning and specialized cushioning rather than compression therapy.

Conclusion

The correct answer is C, as elastic stockings are specifically utilized to decrease edema by enhancing venous return and preventing fluid accumulation in the legs. Other options, while related to health concerns, do not accurately represent the primary function of elastic stockings, which is centered around managing swelling rather than blood pressure, wound healing, or pressure sore prevention.
