The patient asks why preoperative application of compression stockings has been ordered. Which response by the nurse is most appropriate?
a. "They help to prevent any chance of blood clots after surgery.".
b. "They are measured from behind the knee to the heel.".
c. "They are connected to a pump that com-presses different parts of the leg at differ-ent times to help the circulation in your legs after surgery.".
d. "They put continual light pressure on your legs to improve venous return after sur-gery.".
D
The purpose of compression stockings is to promote circulation during periods of immobilization, reducing the risk of an embolism. They cannot prevent any chance of blood clots because blood clots can develop in other body areas for other reasons. The method of measurement doesn't answer the patient's question about why they are used. The devices connected to a pump to pro-mote circulation in the lower extremities are called sequential compression devices.
