Which phrase describes the application method of TED hoses?

TED hoses, or thromboembolic deterrent stockings, are designed to provide graduated compression to the legs, which aids in promoting blood circulation and reducing the risk of blood clots. The phrase "tightly fitted for support" accurately describes their application method because the compression from these stockings is crucial for them to be effective. They need to fit snugly yet comfortable to ensure that they apply the correct amount of pressure at the ankle and gradually decrease as they move up the leg. This graduated compression helps in facilitating venous return in patients, especially those who are immobile or at risk for venous thromboembolism.

The other options do not align with the purpose and application of TED hoses. Loose fitting would not provide the necessary support to improve circulation; applying them only during sleep would limit their effectiveness in providing all-day support; and wearing them solely during physical activities does not utilize their primary function of preventative care for those who may be at risk for clot formation throughout the day.
