A client who had injection sclerotherapy for varicose veins is advised to wear compression (support) stockings. what is most important for the nurse to explain to the client about compression stockings?

Don the stockings before getting out of bed in the morning.

To prevent distention of the veins, stockings should be applied before the legs are placed in a dependent position. Stockings should be used preventively before the discomfort associated with venous pressure and edema occurs. Knee-high stockings should end 2 inches (5.1 cm) below the knee to avoid popliteal pressure, which limits venous return. Stockings apply uniform pressure. Elastic bandages may slip or develop wrinkles, creating uneven pressure and constriction; edema may result.
